pasteurella in rabbits, treatment options in SG

updated 19 May 2026

pasteurella in rabbits is one of those conditions that gets underestimated until something goes seriously wrong. it is also more pressing than ever for Singapore owners, because our climate creates near-ideal conditions for chronic respiratory illness in rabbits. temperatures between 28 and 32°C year-round, combined with humidity sitting at 70 to 90%, put constant pressure on a rabbit’s immune system. add limited airflow in many HDB flats and the occasional stressful MRT ride to the vet, and you have a recipe for flare-ups that can spiral quickly if not treated correctly. knowing what pasteurella looks like and what options exist in SG is practical, not optional.

what is pasteurella?

pasteurella multocida is a gram-negative bacterium that many rabbits carry in their upper respiratory tract without ever showing symptoms. the infection becomes a problem when the immune system is weakened or overwhelmed, whether by heat stress, a poor diet, dental disease, a sudden change in environment, or concurrent illness.

once active, pasteurella does not stay neatly in one location. it can spread from the nasal passages to the inner ear, eyes, jaw, lungs, uterus, or spine. this systemic spread is what makes early treatment important. catching it at the snuffles stage is far easier to manage than catching it after an abscess has formed or after a rabbit has developed a head tilt.

signs to watch for

the classic presentation is snuffles: persistent sneezing, nasal discharge ranging from clear to thick white or yellow, and the tell-tale crusty fur on the inside of the front paws from wiping the nose.

other signs include:

  • watery or crusty eyes, sometimes just on one side
  • noisy or laboured breathing
  • head tilt, circling, or loss of balance, which suggests inner ear involvement
  • a lump or swelling on the jaw, cheek, or neck from an abscess
  • reduced appetite, hunched posture, or hiding more than usual

in Singapore’s heat, a rabbit with a respiratory infection can deteriorate faster than you might expect. if your rabbit is breathing with visible effort, has developed a sudden head tilt, or has stopped eating for more than 12 hours, do not wait. contact a SG exotic vet as soon as possible.

how vets diagnose it in SG

a thorough diagnosis matters because treatment should be guided by which antibiotics the specific bacterial strain responds to, not by guesswork.

your vet will start with a physical exam and a full history of your rabbit’s symptoms. from there, common diagnostic steps include:

  • nasal or abscess culture and sensitivity testing: a lab swab identifies the bacteria and maps which antibiotics will work against it. results typically come back within several days.
  • x-rays or CT imaging: shows whether infection has spread into the skull, tooth roots, or chest cavity. CT scanning for rabbits is available at a small number of SG specialist facilities as of 2026.
  • blood work: a complete blood count and biochemistry panel helps the vet assess organ health before committing to a long antibiotic course.

diagnostic workups in SG for rabbit respiratory conditions can range from SGD 150 for a basic exam and x-ray to SGD 500 or more if culture testing and CT imaging are both involved. costs vary significantly by clinic and case complexity.

it is worth asking upfront whether the vet has specific experience with exotic animals. a vet who mainly sees cats and dogs may not be familiar with rabbit-specific antibiotic contraindications or the techniques required for rabbit abscess management.

treatment options available in SG

there is no single protocol. treatment is shaped by where the infection is, how severe it is, and what culture results show.

antibiotics are the foundation of treatment. commonly used options include enrofloxacin, azithromycin, and trimethoprim-sulfa, sometimes in combination regimens. your vet should ideally base the choice on culture and sensitivity results rather than empirical guessing. the course length is typically long: four to eight weeks is common, and chronic or severe cases may require significantly longer.

important: penicillin-family antibiotics, including amoxicillin, ampicillin, and amoxicillin-clavulanate, are toxic to rabbits. they disrupt gut flora in a way that is often fatal. a rabbit-experienced vet will never prescribe these, but knowing this yourself is useful if you are ever given a prescription by a general practice clinic.

abscess treatment requires a different approach than in cats or dogs. rabbit abscesses contain thick, caseous pus that cannot be drained like a fluid abscess. the standard approach is surgical: complete removal of the abscess capsule or aggressive debridement, followed by long-term antibiotic therapy. jaw abscesses arising from tooth root infections are particularly complex. surgical procedures for abscesses in SG can range from SGD 400 to over SGD 1,200 depending on location, size, and which structures are involved.

supportive care runs alongside any medical treatment. your rabbit needs to keep eating; gut stasis is a real risk when a rabbit is in pain or on antibiotics. Oxbow Critical Care, syringe-fed if necessary, helps maintain gut motility. keeping your rabbit’s living space cool with AC set to 22 to 24°C reduces immune stress during recovery.

eye treatment often accompanies nasal pasteurella, because the same bacteria can travel through the nasolacrimal duct to the eye. antibiotic eye drops or ointment prescribed by your vet can manage conjunctivitis while systemic antibiotics address the underlying infection.

living with a pasteurella-positive rabbit

a full cure is not always possible. many rabbits carry pasteurella for life, with flare-ups triggered by stress, illness, or environmental changes. the goal shifts from cure to management: reducing the frequency and severity of episodes while keeping your rabbit’s quality of life high.

practical steps for SG owners:

  • keep the environment consistently cool: heat above 30°C is a known immune stressor for rabbits. AC is not a luxury for a pasteurella rabbit, it is part of the treatment plan.
  • hay as the dietary foundation: a rabbit eating unlimited timothy hay or orchard grass has better gut health and stronger immunity than one on a pellet-heavy diet. this matters for long-term resilience.
  • twice-yearly vet checks at minimum: more often if your rabbit has active or recurring symptoms.
  • quarantine new rabbits: pasteurella spreads between rabbits in close-contact living situations. any newly adopted rabbit should be kept separate for at least 30 days and ideally screened before living with your existing rabbit.
  • reduce environmental stressors: construction noise, frequent handling changes, and nearby predator animals all suppress rabbit immunity. a calmer home environment supports a more stable immune response.

what owners often get wrong

stopping antibiotics early: this is the most common mistake. your rabbit looks better at week two, so you stop. pasteurella does not clear that quickly. incomplete courses drive antibiotic resistance and almost guarantee a relapse, often worse than the first episode.

assuming sneezing is seasonal or minor: rabbits are obligate nasal breathers. repeated sneezing with discharge is not hay fever. it is a clinical sign that warrants examination by an exotic vet, not watchful waiting at home.

delaying to avoid vet costs: exotic vet fees in SG are real. but an early nasal infection treated promptly is far less expensive than abscess surgery or managing permanent inner ear damage. the longer an infection spreads, the more complex and costly treatment becomes.

medicating with non-prescribed antibiotics: giving your rabbit leftover cat or dog antibiotics is dangerous. some antibiotics safe for other animals are lethal to rabbits. only use medications prescribed by a vet who has confirmed experience with rabbits.
