Diagnose via virus isolation, immunofluorescence, RT-PCR. Persistently infected immunotolerant animals. Transplacental spread may cause abortion, gross abnormalities, Transmitted via contact, fomites, contaminated feed. Disease generally mild and self limiting, however mucousal disease is fatal.Control is only in humans, vaccination & mosquito control After bite, virus replicates locally, causes Range from fever, CNS signs, blindness, lethargy, sweating, collapse, death. Piggs show no signs, pregnant sows may abort. Infects people, pigs, horses, birds, cattle dogs & other vertebrates.Infects fibroblast, vascular endothelium & cells of reticuloendothelium. Important respiratory disease of chickens.Production of antibody causes arthus-type reaction Severity of infectionĭependant on ability of FIP to infect monocytes & macrophages. Mutation of feline enteric coronavirus.Can detect via virus isolation, HI or virus neutralisation. Replication in the vagus causes gastric stasis -> vomiting. Causes either encephalomyelitis or vomiting & wasting disease.Immunofluorescence, PCR & antigen capture ELISA used to diagnose. Mortality & morbidity vary between farms. Similar disease to TGE, but virus is unrelated.Deletion mutant of TGE, causes inaparent respiratory disease.Diagnose via immunofluorescence on SI, antigen ELISA on faecal samples, PCR to distinguishįrom PRCOV. Requires high biosecurity to prevent introductionįoxes, dogs & cats may harbour virus. High mortality in young piglets, unthriftyness. Vaccination to increase lactogenic immunity Virus can be detected in faeces via neutralisation ELISA, electron microscopy. Virus replicates in vilous enterocytes in small intestine & colon. second most significant cause of diarrhea.Porcine haemagglutinating encephalomyelitis.Non-contagious, spread by cullicoides, cause vasculitis.Replicate in nucleus causing intranuclear inclusion bodies.Via vaccination and reduction of skin abrasions. Transmission viaĬontaminated environment, inhalation of aerosols, or mechanical by insects.
