Zoonoses

Yesterday we had a discussion on fish borne zoonoses.Now lets have some discussions over other agents of zoonoses.Bird is known to be a very potent cause of zoonoses as they carry various tick vectors.Diseases like Kyasanur Forest Disease,West Nile Virus,Eastern and Western Equine Encephalomyelitis,Tick typhus, Q fever,tularaemia,Crimean Haemorrhoeagic fever are often carried by birds.It is widely believed that Kyasanur Forest Disease was introduced by birds in India by carrying the tick vector Haemophysallis spinigera.We all know how migratory birds and wild waterfowl can carry the dangerous bird flu.Besides monkeys also carry zoonoses like Group C and Guama group of virus,Venezuelan Equine Infectious encephalomyelitis and Kyasanur forest disease.Antibodies of Dengue has been found in monkeys as well.Small mammals carry Largat ,Powanan,Naples,Gr-A,B,C and Guama group of virus,Colorado tick fever,Russian Spring Summer Encephalitis etc.Rat carrying the vector Xenopsyla cheopis is a potent agent of Yernsinia pestis causing plague.
Below is a list of zoonoses by domestic animals

Pig-Cysticercosis,Taeniasia
Cattle-FMD,Cow pox,Brucellosis,Anthrax
