BoHV1 - infectious bovine rhinotracheitis Canine HV1 Feline HV1 Porcine HV1 Aujeczky disease (pseudorabies) Gallid HV2 Mareks disease Herpes virus replicates in tonsils - viraemia - goes to organs with lower temp ( thats is why neonates are more succeptible)

BoHV1.1trans: Resp or genital secretion (semen) and conjuctivapyrexia, RED NOSE, cough, viraemia, abortionsfirst in epithelial cells of nasal mucosaN. trigeminus - latent until stress

Alphaherpesvirus - pseudorabiesporcine - main host and shed virus. NOt zoonoticResp and CNS signs

1. under 1 week - fever, CNS, dog sitting, anorexia -death
2. 3-4 week - resp. signs , gravel voice(pharyngeal lesions), CNS
3. 1-3 montsh - mild fever, anorexia, resp. signs, mild CNS - can recover
4. Adults - anorexia, resp, sings, cough, nasal discharge, pneumonia, abortions, CNS RARE

Report If in carnivores - SEVER PRURITUS and other CNS signs, death in 48 hours. same for RUminants

1. Infectious canine hepatitis - CAV-1. Direct or indirect. First lymph then parenchyma of kidney, liver. cause necrosis and haemorragis. also RT
2. Bovine adenovirus - digestive + RT in calves. less severe than canine one, but 2nd bac. inf. can make it dangerous.
3. Porcine adenovirus
4. Equine adenovirus- mild respiratory, Arabian foals with immunodeficiency.

Papillomaviridae - papillomatosis virus Mostly cattle, can affect Eq. worldwide. 6 types but 1 and 2 most common.

• skin warts, usually regress due to immune response. Inf. through damaged skin.
• Affects keratinocytes and fibroblast causing bening papillomas, firbropapillomas.

vaccine BANNED IN EU also - canine papilloma virus - oral mucosa and lips

Caliciviridae - calicivirus NOT ZOONOTICTrans: saliva, rupture vesicles, fecesonly in US - pigs feed undercooked fish (resevoir)

1. Transmissible gastroenteritis of swine virus - piglets - destruction of epithelial of small intestine. watery smelly diarrhea
2. Feline infectious peritonitis virus - orofecal. Virus mutates and then able to replicate in Macrophages - systemic intracellular pathogen

• Wet FIP - ascites, pleural effusion
• Dry FIP - CNS, ocular, granuloma in peritoneum
