Intranuclear coccidiosis caused by Cyclospora spp. in calves

Control of Coccidiosis in Calves by Vaccination

The immunizing effect of inactivated sporulated oocyst and inactivated sonicated vaccines against bovine coccidiosis was observed in calves. Indirect haemagglutination (IHA) test was developed for detecting antibodies to coccidian. Serum antibody levels in calves were measured against soluble oocyst (sporulated) antigen. IHA antibody titer was significantly higher (P<0.05) in calves vaccinated ...

Case Report of Meningoencephalitis in Calves Caused by Escherichia coli

Calf Note #17 – A Review of Coccidiosis in Calves

Coccidiosis, caused by protozoa of the genus Eimeria, results in health and economic problems to several classes of livestock. The disease reduces feed consumption, body weight, and feed efficiency and may cause mortality of 24% in some cases (Fitzgerald, 1975). An estimated 77 million young cattle in the United States could be infected by coccidia during the first year of their life. Of these,...

Bacteraemia caused by Campylobacter spp.

The genus Campylobacter has become increasingly recognised as the cause of various infections. Campylobacter jejuni and C coli cause acute gastroenteritis in man all over the world. C jejuni enteritis can lead to bacteraemia, but its actual incidence remains unknown. Seven cases of bacteraemia caused by C jejuni or C coli are reported, from the blood of seven patients: five immune deficient adu...

Cyclospora spp. in Drills, Bioko Island, Equatorial Guinea

To the Editor: More than a decade has passed since major outbreaks of Cyclospora cayetanensis infection in the United States and Canada drew attention to this newly emerging infection (1,2). Awareness of these infections was highlighted again by large outbreaks in the summer of 2013 (3). However, many questions remain unanswered regarding this organism, including aspects of its life cycle, geog...
