The clinical signs and pathological lesions which developed in various ages of cattle experimentally infected intranasally with the "Strichen" strain of IBR virus were similar to, but generally milder than, those of the field disease. The clinical signs were most severe 4 days after infection and had almost wholly regressed after 12 days. Serum neutralizing(More)
Nicotine used at approximately 2 ppm in 0.25% toxaphene dip wash was found to be 95% effective in the treatment and control of bovine parasitic otitis after dipping clinically affected cattle twice weekly for twelve weeks. Only three of 64 clinically affected animals failed to recover completely following the above treatment regime. The viable(More)
An epidemiological survey of sarcoptic mange in 32 herds with a total herd size of 2,021 pigs was conducted in three representative climatic zones in Tanzania. The disease was present in all zones in varying prevalences. The overall prevalences were 52% and 21% when determined on the basis of clinical examination and mite isolation respectively and 91% of(More)
A serological survey to determine the prevalence of antibodies to bovine virus diarrhoea-mucosal disease (BVD-MD) virus was conducted on 419 bovine serum samples orignating from 18 of 20 regions (except Mwanza and Shinyanga) of the Tanzania mainland. The sera were a small proportion of samples collected for the appraisal of immune response to rinderpest(More)
Bovine parasitic otitis caused by Rhabditis boris is endemic in the Morogoro, Tanga, Coastal and Dar-es-Salaam regions of Tanzania with morbidites of over 70% (Jibbo, 1966). More recently cases have been diagnosed in the Dodoma, Arusha and Mbeya regions. Outside Tanzania the disease occurs in Botswana, Zimbabwe (Th~Jmpson, pers. comm.) and Kenya (Gacugia,(More)
Between January 1982 and December 1989 more than 5,000 clinical cases of bovine parasitic otitis were examined. Clinical signs were mild in early cases and were characterised by dullness, anorexia and occasional head shaking, but were severe in long standing cases where the major presenting clinical signs were dark brown aural discharges which soiled the(More)
In recent outbreaks of infectious bovine rhinotracheitis (IBR) in Britain a proportion of the animals affected developed a severe clinical disease characterised, at necropsy, by widespread damage to the respiratory tract. They had necrotising rhinitis, pharyngitis, laryngotracheobronchitis with extensive pseudomembrane formation and severe pneumonia with or(More)
