Prevalence of Hemoplasma infection in periparturient cows and neonatal calves

Observation of lymphocyte function in perinatal cows and neonatal calves.

The changes in lymphocyte transformation rate and proportion of E-rosette forming cells (ERFC), in addition with serum concentration Qf IgG and certisol were examined on dairy cows in the perinatal period. The cows were bled at the various stages of pregnancy, parturition and post-parturient period. Also in calves, the lymphocyte transformation rate and proportion of ERFC were examined on the b...

Passive protective effect of anti-K99 antibodies against enterotoxigenic E.coli infection in neonatal calves

BACKGROUND: BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is the main causative agents of neonatal calf diarrhea. Passive transfer of antibodies that is derived from the dams of the calves through their colostrum plays an important role in disease prevention. OBJECTIVES: To determine the presence of natural specific antibodies against K99 antigen in dam’s serum and colostrum as well as in...

Hemoplasma Infection in HIV-positive Patient, Brazil

Hemotrophic mycoplasmas infect a variety of mammals. Although infection in humans is rarely reported, an association with an immunocompromised state has been suggested. We report a case of a Mycoplasma haemofelis-like infection in an HIV-positive patient co-infected with Bartonella henselae.

Prevalence and risk factor analysis of bovine hemoplasma infection by direct PCR in Eastern Hokkaido, Japan.

The prevalence and risk factors of 2 bovine hemoplasma species-Mycoplasma wenyonii (Mw) and "Candidatus Mycoplasma haemobos" (CMh)-were examined by direct PCR using whole blood samples collected from 343 cattle in Eastern Hokkaido, Japan. The sensitivity of the direct PCR assay was 10-fold higher than the standard PCR assay, detecting 5 copies of bovine hemoplasma DNA per reaction. An epidemiol...
