-
Diagnosis:
- ELISA tests: detect FeLV antigen in the blood.
- IFA testing: detect infected leukocytes and platelets in blood.
- Chemistry profiles: reveal abnormalities based on affected organs.
- Radiology: confirm thoracic and abdominal effusions.
- Fluid analysis:
- High total fluid protein with more than 50% globulins suggests FIP.
- Low nucleated cell count and pyogranulomatous exudate in FIP fluid.
- Stringy or sticky fluid that clots when refrigerated.
- Cerebrospinal fluid analysis: reveals high protein concentration and elevated nucleated cell count.
- FCoV antibody titers in serum or effusions:
- Positive but low titer: FIP is possible, but clinically confirmed.

- There is no known cure for FIP.
- Prevention of FIP includes vaccination against FCoV and CPIV.
- D-lysine therapy may reduce the replication of FHV.
- Bordetella vaccination (killed vaccine) may also be considered.
- Intranasal (modified live-virus vaccine [MLV]) vaccines provide better protection.
- Immunity for Bordetella lasts for 6 months or less.
- Vaccination is not 100% effective.
- FIP is not transmissible to humans.
Canine Infectious Tracheobronchitis (Kennel Cough)
- Kennel cough is caused by a combination of viruses and bacteria.

- Preventative measures include vaccination and isolating new dogs for 3 weeks.
- Kennel cough is not transmissible to humans.
Rabies
- Rabies is caused by a virus of the Rhabdoviridae family.
- Rabies is a zoonotic disease, meaning that it can be transmitted from animals to humans.
- Wild animals such as skunks, raccoons, bats, foxes, and coyotes are reservoirs for the virus.
- Rabies is transmitted through saliva, usually by a bite wound.
- The incubation period for rabies can range from 2 to 8 weeks or longer depending on the location of the wound.
- Rabies is fatal in both humans and animals.
- Early symptoms of rabies can be nonspecific and include fever, headache, and lethargy.
- Preventative measures include vaccination, especially for people at high risk.
- If a dog or cat bites a human, it should be confined, isolated, and observed for 10 days.
- If a wild animal bites a human, euthanasia and testing are required.
- If the exposed animal is unvaccinated, euthanasia is recommended.
- If euthanasia is not allowed, isolation is required for 6 months.

Systemic Bacterial Infectious Disease
Leptospirosis
- Leptospirosis is caused by bacteria of the genus Leptospira.

- Prevention of rabies in humans is critical, as clinical cases are fatal.
Feline Leukemia Virus (FeLV)
- Infected queens can shed the virus in their milk.
- Exposure typically occurs through direct contact like grooming, bite wounds, and sharing food/water bowls.
- FeLV can be transmitted transplacentally.
- FeLV survives in the environment for a maximum of 48 hours and is easily destroyed by disinfectants.
Pathogenesis of FeLV
- After entry, FeLV replicates in lymphoid tissue throughout the body.
- If the immune response is effective, the infection may be eliminated.
- FeLV infects bone marrow, leading to the circulation of infected leukocytes and platelets.
- FeLV infects glandular cells, and the virus is shed in body secretions.
Clinical Signs of FeLV
- FeLV-related neutropenia or thrombocytopenia could occur.
- Secondary infections are common and may include viral, fungal, protozoal, Mycoplasma, and bacterial causes.
- Peripheral lymph node hyperplasia can be seen, especially in young adult cats.
- Immune-mediated disorders such as immune-mediated hemolytic anemia, immune-mediated thrombocytopenia, immune-complex glomerulonephritis, polyarthritis, pemphigus, and systemic lupus erythematosus-like syndrome may occur.
- Infected queens may have reproductive failure. This includes infertility, fetal resorption, abortion, stillbirth, fading kitten syndrome, and milk-borne transmission.
Diagnosis of FeLV
- Test all cats before vaccination and before bringing a new cat into the house or cattery.
Feline Infectious Peritonitis (FIP)
- FIP occurs when the enterotropic FCoV mutates, allowing it to infect and replicate in macrophages.
- Macrophages carry the mutated virus to peritoneum, pleura, kidney, uvea, and the nervous system.
- The immune reaction to the virus causes disease.
Epidemiology of FIP
- Seroprevalence for FCoV is high, but few cats develop FIP.
- Prevalence is highest in catteries and shelters.
- Young cats (6 months to 3 years) are at increased risk of FIP.
- Cats in catteries, shelters, or multiple cat households are at higher risk of FIP.
- Anything that causes increased replication of FCoV, such as CAV-2, herpesvirus, reovirus, and mycoplasmas, may play a role.
Clinical Signs of FIP
- Effusive FIP is characterized by accumulation of fluid in the body cavities, especially the abdomen.
- Noneffusive (dry) FIP is characterized by pyogranulomatous inflammation and necrotizing vasculitis in multiple organs.
- Affected organs include the kidney, liver, spleen, visceral lymph nodes, uvea, retina, brain, lungs, and testicles.
- Meningoencephalitis and myelitis are common, leading to ataxia, tremors, vestibular dysfunction, seizures, paresis, and behavioral changes.
- Hydrocephalus can occur.
Diagnosis of FIP
- Hematology and serum chemistries: Total serum protein and globulins are increased in most cases. Albumin is commonly decreased, leading to a decreased serum albumin:globulin ratio (<0.8), strongly suggesting FIP.
Canine Distemper
- Canine distemper is a highly contagious viral disease affecting dogs.
- The virus is a morbillivirus, related to measles in humans and rinderpest in cattle.
- Canids (dogs, wolves, coyotes, foxes, jackals) are naturally susceptible. Other animals like raccoons, ferrets, skunks, lions, ocelots, bears, pandas, and hyenas can also be infected.
Transmission of Canine Distemper
- Primarily inhalation through respiratory secretions.
- Virus shed in all secretions and excretions for up to 1 to 2 weeks after recovery.
- Virus survives for a few days in the environment and is easily killed by disinfectants.
Pathogenesis of Canine Distemper
- Infection of the upper respiratory tract starts the process.
- CDV spreads to lymphoid tissues, including liver, spleen, and GI tract, causing severe immunosuppression.
- Viremia occurs, and CDV spreads to epithelial tissues and the central nervous system (CNS), influencing the outcome based on the immune response.
Clinical Signs of Canine Distemper
- Young puppies usually show high fever, vomiting, diarrhea, dehydration, and anorexia.
- In susceptible adult dogs, infection is usually subclinical.
- Infection in utero near the end of gestation or within the first few weeks of life can result in cerebellar hypoplasia, leading to ataxia and intention tremors.
Diagnosis of Canine Distemper
- Diagnosis is based on clinical signs in an unvaccinated kitten.
- Leukopenia can be profound and last for 2 to 4 days.
- If leukopenia persists for more than 5 days or nonregenerative anemia is present, consider FeLV infection.
- Definitive diagnosis requires fecal PCR or virus isolation.
Treatment of Canine Distemper
- Treatment is supportive (intensive fluid therapy, antibiotics, antiemetics, dietary restriction).
Prognosis of Canine Distemper
- Prognosis is poor if hypothermia, shock, jaundice, or DIC develops.
Prevention of Canine Distemper
- Vaccination is highly effective.
- Maternal antibodies interfere with protection by vaccination, leading to a 2- to 4-week period during which puppies are susceptible to infection but refractory to vaccination.
