Abstract: Sudden death is a serious problem in farm animals. It may occur due to microbial or non-microbial causes. Non-microbial causes may occur sporadically due to internal hemorrhage, severe trauma, rupture of the gut. Farm animals subjected to stressful conditions are highly susceptible to microbial causes of sudden death. It may occur due to bacterial infection as C. chauvoei with spread of vegetative form, producing active toxin. C. tetani produce tetanospasmin which attack CNS causing deaths due to respiratory failure. C. botulinuminfection end with complete loss of muscle tone. B. anthracis infection proceeds rapidly showing bleeding from the natural orifices after death. MRSA cause mortality in infected horses. S.equi infected horses show abscesses which obstruct breathing. Salmonella infection shows fever, bloody diarrhea, acute respiratory disease and deaths. Multifactorial diseases causing sudden death in newborn animals include colitis-X and calf scour. The impact of bacterial causes of sudden death in farm animals results in high economic losses due to costs of eradication, decontamination and vaccination programs. Accurate and rapid diagnosis of sudden death cases is essential for setting of control programs to improve animal husbandry.
