Feline Leukemia is a retrovirus. As a member of the retrovirus family, the feline leukemia virus’s genetic material is transmitted as RNA. Once the virus infects the cell, DNA copies of the virus are transcribed and these copies are inserted randomly into the host’s genetic material. Once the DNA is integrated within the genome, any cell division that occurs will cause both of the new cells to contain the virus.
Feline Calicivirus (FCV) is an important and common cause of Upper Respiratory Infection (URD) and oral disease in cats. This virus occurs worldwide with various strains that vary greatly in virulence (the ability to produce disease). Clinical disease may vary from subclinical (not clinically apparent) to combinations of oral, respiratory disease, and lameness. There are more than 40 strains of FCV, one of which may have high mortality rates and is referred to as the virulent systemic (VS), or the hemorrhagic form of FCV.
Rabies is a virus that may infect the central nervous system of any warm blooded animal. Rabies is typically spread by the saliva from infected animals. Horses are most likely to contract rabies by the bite of a wild carnivore, bats, or unvaccinated cats. Rabies is essentially 100% fatal once clinical signs attributed to the disease are exhibited.
In the year 2001 there were nearly 7,500 cases of rabies that were reported to the Centers for Disease Control and Prevention in the US. Of those cases, 51 were members of the Equine Family.
Ticks are essentially large mites that are covered with a leathery integument. A tick’s sole purpose is sucking blood from mammals, birds and reptiles, and then reproducing to provide the next generation. Ticks are not insects, but arachnids. An adult will have eight legs and three body segments. As arachnids, ticks are related to spiders, chiggers, scorpions and mites.
Commonly known as "snuffles," nasal catarrh, or pasteurellosis, is a highly contagious bacterial infection affecting rabbits. Snuffles produces a discharge from the nose and eyes.
Kennel Cough--or Infectious Tracheobronchitis--is an easily transmitted combination bacterial/viral disease in the canine patient. It is caused by a bacterial infection of Bordetella bronchiseptica and viral components parainfluenza and canine adenovirus. Tracheobronchitis is a highly infectious condition seen 5 to 10 days following exposure to the causative agents.
