Pasteurella is an important bacterial infection rabbit owners and farmers should understand because it can affect much more than the nose.
The bacterium most commonly associated with pasteurellosis in rabbits is Pasteurella multocida. It can be associated with respiratory disease, eye problems, ear infections, abscesses, pneumonia and, in more serious cases, infection involving other parts of the body.
However, finding Pasteurella in a rabbit does not automatically mean that the rabbit is sick.
Some apparently healthy rabbits can carry the organism without showing obvious signs of disease. This makes proper veterinary diagnosis particularly important.
A rabbit that is sneezing should therefore not automatically be diagnosed with Pasteurella, and owners should never begin antibiotics simply because they have read about the condition online.
This guide explains what Pasteurella in rabbits is, possible symptoms, how veterinarians diagnose it, how infections may be treated, how it can spread between rabbits, and what owners can do to reduce the risk of disease.
What Is Pasteurella in Rabbits?
Pasteurella multocida is a bacterium capable of colonising rabbits and causing a condition known as pasteurellosis.
The organism is particularly associated with the respiratory system but can also affect several other parts of the body.
An important point is that some rabbits can carry Pasteurella without appearing ill.
These rabbits are sometimes described as asymptomatic carriers.
Because carriage can occur without disease, identifying the bacterium in a sample does not necessarily prove that it is responsible for every symptom a rabbit is showing.
Veterinarians consider the rabbit’s symptoms, physical examination and laboratory findings together before reaching a diagnosis.
Is Pasteurella the Same as Snuffles?
Not exactly.
“Snuffles” is an informal term commonly used for upper respiratory disease in rabbits.
Pasteurella multocida is an important cause of snuffles, but it is not the only possible cause.
Other bacteria and medical problems can cause similar symptoms.
A rabbit with sneezing or nasal discharge may therefore require diagnostic testing rather than being automatically labelled as having Pasteurella.
This distinction matters because the correct treatment depends on the actual cause.
How Common Is Pasteurella in Rabbits?
Pasteurella exposure and carriage can be relatively common in rabbit populations.
Some rabbits may carry the organism while remaining healthy, whereas others develop clinical disease.
Whether a rabbit becomes sick can depend on several factors, including:
- The strain of bacteria involved
- The rabbit’s general health
- Immune status
- Housing conditions
- Ventilation
- Sanitation
- Other illnesses
- Stress
- Population density
The presence of Pasteurella alone does not tell you how severely a rabbit will be affected.
What Can Trigger Clinical Disease?
A rabbit carrying Pasteurella may not show signs continuously.
Disease can sometimes become apparent when the animal is placed under additional physical or environmental stress.
Possible contributing factors may include:
- Poor ventilation
- Overcrowding
- Poor sanitation
- Inadequate nutrition
- Another illness
- Major environmental changes
- Reproductive stress
- Poor air quality
This does not mean stress directly “creates” Pasteurella.
The bacteria must already be present for pasteurellosis to occur.
Instead, stressful or unhealthy conditions may reduce the rabbit’s ability to keep infection under control.
Symptoms of Pasteurella in Rabbits
Pasteurellosis can look different depending on which part of the body is affected.
Some rabbits develop relatively mild respiratory symptoms, while others may become seriously ill.
Possible presentations include respiratory disease, eye problems, ear infections, abscesses, pneumonia, reproductive infections and systemic illness.
1. Sneezing and Nasal Discharge
One of the most familiar presentations is upper respiratory disease.
Possible signs include:
- Repeated sneezing
- Nasal discharge
- Wetness around the nose
- Thick or pus-like discharge
- Noisy breathing
- Reduced activity
Nasal discharge may begin relatively thin and become thicker as disease progresses.
However, sneezing by itself does not diagnose Pasteurella.
Dusty hay, environmental irritation, foreign material and other infectious organisms can also cause respiratory symptoms.
Persistent sneezing or discharge should therefore be assessed by a veterinarian.
2. Matted Fur on the Front Paws
Rabbits frequently wipe their noses and faces using their front paws.
Because of this, respiratory or eye discharge may sometimes be noticed on the front legs rather than directly around the nose.
Owners may see:
- Wet fur
- Matted fur
- Crusted material
- Thinning of fur
around the inside of the front paws.
This can be an important clue that the rabbit has been repeatedly wiping discharge from its nose or eyes.
3. Eye Problems
Pasteurella may be associated with eye and tear-duct problems in some rabbits.
Possible signs include:
- Watery eyes
- Thick eye discharge
- Redness
- Squinting
- Wet fur beneath the eye
- Repeated rubbing of the face
However, rabbit eye discharge has several possible causes.
Dental disease can also affect the tear ducts, and irritation or other infections may cause similar symptoms.
A persistent runny eye should therefore not automatically be treated as Pasteurella.
Veterinary examination may be necessary to identify the underlying problem.
4. Pneumonia and Lower Respiratory Disease
Pasteurella can sometimes be involved in infection of the lungs.
Pneumonia is considerably more serious than a mild upper respiratory infection.
Possible warning signs include:
- Rapid breathing
- Difficult or laboured breathing
- Reduced appetite
- Severe lethargy
- Weakness
- Reduced activity
Any rabbit struggling to breathe needs urgent veterinary attention.
Do not wait for respiratory symptoms to become severe before seeking help.
5. Ear Infections and Head Tilt
Pasteurella can be associated with infection of the middle or inner ear.
Possible signs of ear disease include:
- Head tilt
- Loss of balance
- Circling
- Difficulty standing normally
- Ear discomfort
- Abnormal head position
However, head tilt is not specific to Pasteurella.
Other conditions, including infections caused by other bacteria and neurological disease associated with Encephalitozoon cuniculi, can produce similar symptoms.
A rabbit with head tilt requires veterinary assessment to determine the cause.
Imaging such as X-rays or CT scans may sometimes be required when middle or inner ear disease is suspected.
6. Abscesses
Pasteurella can also be associated with abscess formation.
Rabbit abscesses are different from the thin, easily drained abscesses people may be familiar with in some other animals.
Rabbit pus is often extremely thick.
Abscesses can develop:
- Beneath the skin
- Around the face
- Around the jaw
- Near tooth roots
- In deeper tissues
- Within internal organs
A lump on a rabbit should not automatically be assumed to be a Pasteurella abscess because several other conditions can cause swelling.
Veterinary investigation is necessary.
Why Rabbit Abscesses Can Be Difficult to Treat
Rabbit abscesses often contain thick material surrounded by a substantial capsule.
Simply squeezing or opening an abscess at home is not appropriate treatment.
Depending on the location and severity, veterinary management may involve surgical removal, cleaning of affected tissue, antimicrobial treatment and investigation of any underlying cause.
Facial abscesses, for example, can sometimes be related to dental disease.
This makes proper diagnosis important.
7. Reproductive Tract Infection
Pasteurella can sometimes be associated with infection of the reproductive system.
Female rabbits may develop infection involving the reproductive tract, while males may also experience genital infections.
However, Pasteurella is not the only organism capable of causing reproductive disease.
Signs such as abnormal genital discharge, swelling, pain, infertility or illness should therefore be investigated by a veterinarian rather than diagnosed from symptoms alone.
8. Septicaemia and Severe Systemic Disease
In severe cases, bacteria may spread through the bloodstream and cause systemic infection.
This is potentially life-threatening.
A severely affected rabbit may become:
- Extremely weak
- Unresponsive
- Unable to eat
- Very lethargic
- Seriously ill
Sudden death can occur in severe disease, although this is not how every Pasteurella infection develops.
Any rabbit showing severe weakness, respiratory distress, collapse or rapidly worsening illness needs urgent veterinary attention.
How Is Pasteurella Diagnosed?
A veterinarian should not diagnose pasteurellosis from sneezing alone.
Diagnosis normally starts with:
- Medical history
- Physical examination
- Symptoms
- Assessment of the respiratory system and other affected areas
Depending on the case, further investigation may include bacterial culture and antimicrobial susceptibility testing.
Blood tests may also be useful.
For deeper infections, pneumonia, abscesses or ear disease, diagnostic imaging may be recommended.
This can include:
- X-rays
- Ultrasound
- CT scanning
The tests needed depend on where the infection is suspected.
Why Bacterial Culture Is Important
A bacterial culture attempts to identify organisms present in a sample.
Antimicrobial susceptibility testing can then help determine which antibiotics may be effective against the cultured organism.
This is particularly important because bacterial resistance can make some treatments ineffective.
However, Pasteurella can sometimes be found in clinically normal rabbits.
A positive result must therefore be interpreted together with the rabbit’s symptoms and examination findings.
In other words:
Positive Pasteurella test + no appropriate clinical evidence does not automatically equal Pasteurella disease.
Your veterinarian has to interpret the whole case.
Can Pasteurella in Rabbits Be Treated?
Yes, clinical pasteurellosis can often be treated or managed, but the outcome depends on factors such as:
- Location of infection
- Severity
- Duration of disease
- Antibiotic susceptibility
- Presence of abscesses
- Other health problems
- Individual response to treatment
Chronic Pasteurella infection can be difficult to eliminate completely.
Treatment may control clinical signs without necessarily removing the organism permanently.
Relapses can therefore occur in some rabbits.
Antibiotic Treatment
Antibiotics are often part of treatment for bacterial Pasteurella infections.
However, the exact antibiotic, route and duration should be determined by a veterinarian.
Whenever practical, culture and susceptibility testing can help guide treatment.
Never Self-Medicate a Rabbit With Antibiotics
This point is extremely important.
Do not give a rabbit leftover human antibiotics, dog medication, cat medication or antibiotics purchased without veterinary direction.
A rabbit’s digestive system is highly sensitive to disruption of normal gut bacteria.
Certain antibiotics, particularly when given by inappropriate routes, can cause severe and potentially fatal intestinal disease in rabbits.
An antibiotic that is safe for a dog or human may therefore be dangerous for a rabbit.
Only use an antimicrobial medication under veterinary guidance.
Supportive Treatment
Depending on the rabbit’s condition, veterinary treatment may involve more than antibiotics.
Supportive care can sometimes include:
- Fluids
- Pain management
- Anti-inflammatory treatment
- Nutritional support
- Eye medication
- Ear treatment
- Nebulisation
- Treatment of tear-duct disease
- Surgery for certain abscesses
Not every rabbit requires all of these treatments.
The treatment plan should be based on the individual disease presentation.
What Is Nebulisation?
Nebulisation may sometimes be used as part of veterinary management of respiratory disease.
A nebuliser turns liquid into a fine mist that can be inhaled.
However, rabbit owners should not place medication into a nebuliser without veterinary instructions.
The appropriate solution and whether nebulisation is useful depend on the rabbit’s condition.
What Happens If a Rabbit Stops Eating?
Ill rabbits may reduce or stop food intake.
This is particularly concerning in rabbits because their digestive systems depend on regular movement and fibre intake.
If a rabbit with suspected respiratory disease significantly reduces food intake or stops eating, contact a veterinarian promptly.
Veterinary care may include nutritional support after the rabbit has been examined and the underlying problem assessed.
Do not assume that respiratory disease is the only reason for appetite loss.
Can Pasteurella Be Cured Completely?
Not always.
Some rabbits respond very well to treatment and remain free of clinical signs for long periods.
Other rabbits develop chronic or recurring disease.
Veterinary sources note that antimicrobial treatment may control symptoms without completely eliminating the organism.
For a rabbit with chronic disease, the goal may become maintaining:
- Comfortable breathing
- Good appetite
- Stable weight
- Normal activity
- Acceptable quality of life
rather than guaranteeing permanent eradication.
This is why follow-up veterinary care can be important.
Is Pasteurella Contagious Between Rabbits?
Yes. Pasteurella can spread between rabbits.
Transmission can occur through close contact with infected secretions and contaminated materials.
Possible routes include contact with:
- Nasal discharge
- Eye discharge
- Pus from infected areas
- Contaminated bowls
- Contaminated equipment
- Bedding and housing materials
Direct rabbit-to-rabbit contact is an important route of transmission.
Because some rabbits can carry the organism without obvious symptoms, completely preventing exposure can be difficult.
Should a Sick Rabbit Be Separated?
A rabbit showing signs of a potentially contagious respiratory illness should be assessed promptly.
Where several rabbits are kept together, veterinary advice should be sought regarding isolation and management.
This is especially important in:
- Breeding facilities
- Rabbit farms
- Rescue centres
- Boarding environments
- Multi-rabbit households
However, bonded rabbits can also become stressed by sudden separation.
The correct decision may therefore depend on the disease, severity, housing situation and relationship between the rabbits.
Ask a rabbit-experienced veterinarian how best to manage the affected animals.
Quarantine New Rabbits
Introducing a new rabbit directly into an established group can increase the risk of introducing infectious disease.
A quarantine period allows time to observe the new rabbit for signs such as:
- Sneezing
- Nasal discharge
- Eye discharge
- Diarrhoea
- Parasites
- Skin disease
- Poor appetite
- Other illness
Veterinary sources commonly recommend isolating newly acquired rabbits for approximately one month before introducing them to existing rabbits.
Quarantine should involve separate equipment and good hygiene rather than simply putting the new rabbit in a cage beside the others.
Improve Ventilation
Good air quality is particularly important when trying to reduce respiratory disease.
Rabbit housing should provide good ventilation without exposing rabbits to extreme weather.
Poor ventilation can allow ammonia from urine to accumulate.
High ammonia levels can irritate the eyes and respiratory tract and create poor living conditions.
Remove waste regularly and make sure fresh air can circulate through the rabbitry.
In Ghana and other warm climates, ventilation also plays an important role in preventing heat stress.
Keep Housing Clean
Good sanitation cannot guarantee that Pasteurella will never occur, but it is an important part of disease management.
Regularly:
- Remove accumulated waste
- Clean dirty feeding equipment
- Keep drinking containers clean
- Replace heavily soiled bedding
- Keep housing dry
- Wash hands between groups where necessary
- Clean shared equipment
Avoid overcrowding.
Crowded conditions can increase stress, reduce air quality and make infectious disease more difficult to control.
Reduce Unnecessary Stress
Stress alone does not cause Pasteurella infection, but poor conditions can contribute to disease problems in rabbits already carrying infectious organisms.
Maintain:
- Consistent feeding
- Appropriate housing
- Suitable temperatures
- Good ventilation
- Adequate space
- Clean water
- Appropriate companionship
- Predictable handling
Major changes should be introduced as calmly as possible.
Pasteurella Management on Rabbit Farms
Pasteurella can be particularly important in commercial or breeding rabbitries because respiratory infection can spread through groups of animals.
Farmers should pay attention to:
- Quarantine
- Ventilation
- Stocking density
- Cleaning
- Equipment sharing
- Breeding records
- Sick-animal identification
- Veterinary investigation of outbreaks
Do not treat an entire rabbit population repeatedly with antibiotics without appropriate veterinary guidance.
Unnecessary antimicrobial use can contribute to resistance and may also expose rabbits to avoidable medication risks.
If several rabbits begin sneezing or developing discharge at the same time, seek professional veterinary help to investigate the outbreak.
Pasteurella and Rabbits in Hot African Climates
Warm climates introduce additional management considerations.
Rabbit houses in Ghana and similar regions should have enough ventilation to control both heat and air quality.
The building should remain:
- Shaded
- Dry
- Properly ventilated
- Easy to clean
- Protected from heavy rain
- Free from excessive waste accumulation
During the rainy season, closing every opening to stop rain may cause ventilation problems.
Housing should therefore protect rabbits from weather without creating a sealed, humid environment.
Good rabbitry design supports both respiratory health and temperature control.
Can Humans Catch Pasteurella From Rabbits?
Pasteurella multocida can infect humans, although human infections are much more commonly associated with exposure to animals such as cats and dogs.
Basic hygiene is still sensible when caring for rabbits, particularly sick rabbits.
Wash your hands after:
- Handling nasal or eye discharge
- Cleaning wounds or abscess material
- Cleaning dirty housing
- Handling contaminated equipment
Avoid allowing an animal to lick an open wound.
Anyone bitten or scratched who develops increasing redness, swelling, pain or other signs of infection should seek appropriate medical advice.
People with weakened immune systems should take particular care with animal hygiene and discuss concerns with a healthcare professional.
Can Pasteurella Be Prevented Completely?
It may not always be possible to guarantee that a rabbit will never encounter Pasteurella.
The practical goal is to reduce disease risk and detect problems early.
Important preventive measures include:
- Quarantining new rabbits
- Providing good ventilation
- Avoiding overcrowding
- Maintaining clean housing
- Providing appropriate nutrition
- Reducing unnecessary stress
- Monitoring rabbits daily
- Separating equipment where disease is suspected
- Obtaining veterinary assessment for persistent respiratory signs
Is There a Pasteurella Vaccine for Rabbits?
There is no routinely used Pasteurella vaccine for ordinary pet rabbits comparable to the standard vaccination programmes used for some major viral rabbit diseases.
Disease control therefore relies heavily on good husbandry, hygiene, quarantine, monitoring and appropriate veterinary management.
Vaccine availability and recommendations can differ by country and production system, so commercial rabbit farmers should discuss local disease-control options with an appropriate veterinarian.
When Should You See a Veterinarian?
Contact a rabbit-experienced veterinarian if you notice persistent:
- Sneezing
- Nasal discharge
- Eye discharge
- Head tilt
- Balance problems
- Abscesses or unusual lumps
- Reduced appetite
- Weight loss
- Lethargy
Seek urgent veterinary attention if the rabbit develops:
- Difficulty breathing
- Open-mouth breathing
- Severe weakness
- Collapse
- Inability to eat
- Rapid deterioration
Respiratory problems can become serious and should not be managed solely using home remedies.
Frequently Asked Questions About Pasteurella in Rabbits
Does Every Sneezing Rabbit Have Pasteurella?
No.
Sneezing can have several causes, including environmental irritation and other respiratory infections.
Persistent symptoms should be investigated by a veterinarian.
Can a Healthy Rabbit Carry Pasteurella?
Yes.
Apparently healthy rabbits can carry Pasteurella multocida without showing clinical disease.
This is why laboratory results must be interpreted together with symptoms and veterinary examination.
Is Snuffles Always Caused by Pasteurella?
No.
Pasteurella is an important cause of rabbit respiratory disease, but other organisms can cause similar symptoms.
“Snuffles” describes a clinical respiratory problem rather than identifying one guaranteed bacterial cause.
Can Pasteurella Cause Head Tilt?
Yes, Pasteurella-associated middle or inner ear infection can result in head tilt.
However, there are other causes of head tilt in rabbits, including E. cuniculi and other ear diseases.
Veterinary diagnosis is necessary.
Can Pasteurella Cause Abscesses?
Yes.
Pasteurella can cause abscesses in rabbits, although other bacteria and conditions can also cause them.
Rabbit abscesses often require specialised veterinary treatment because their contents are very thick.
Can I Treat Pasteurella at Home?
No.
Suspected Pasteurella infection requires appropriate veterinary diagnosis and treatment.
Do not administer antibiotics without veterinary direction.
Will Antibiotics Permanently Cure Pasteurella?
Not necessarily.
Antibiotics can help control clinical infection, but chronic disease can recur and complete elimination of the organism may be difficult.
The outcome depends on the location and severity of disease and the rabbit’s individual response.
Should I Separate a Rabbit With Snuffles?
Potentially contagious disease needs careful management, particularly when several rabbits live together.
However, separation decisions should take the rabbit’s social relationships and disease status into account.
Ask your veterinarian how to manage the affected rabbit and its companions.
Final Thoughts
Pasteurella in rabbits is more complicated than simply seeing a rabbit sneeze and calling the condition “snuffles.”
Pasteurella multocida can be associated with respiratory disease, pneumonia, eye and tear-duct problems, ear disease, abscesses, reproductive infections and serious systemic illness.
At the same time, some healthy rabbits can carry the organism without showing disease.
This is why proper diagnosis matters.
Persistent respiratory symptoms should be evaluated rather than treated with random antibiotics or home remedies.
Where bacterial infection is suspected, veterinary examination and laboratory testing can help determine whether Pasteurella or another organism is involved and which treatment is appropriate.
For rabbit owners and farmers, prevention centres on good husbandry: clean housing, good ventilation, appropriate nutrition, sensible quarantine, low stocking density and close daily observation.
If a rabbit develops difficulty breathing, severe weakness, significant appetite loss or rapidly worsening symptoms, seek veterinary help promptly.
Early investigation gives both the rabbit and veterinarian a better chance of managing the problem effectively.
