Effect of water quality on causes of calf mortality in cattle-farm-associated epidemics.

Poor-quality drinking water plays a detrimental role in the suppression of calf immunity, giving rise to an increased rate of calf mortality. The present study aims to evaluate the causes of calf mortality in beef and dairy farms in relation to drinking water quality (DWQ). A convenience sample of 132 Egyptian cattle farms suffering from emerging epidemics was surveyed by collecting drinking water samples for physicochemical and microbial analysis and using a questionnaire to record hygienic risk factors affecting calf health.

Antimicrobial susceptibility and molecular typing of multiple Chlamydiaceae species isolated from genital infection of women in Egypt.

This study investigated the existence of vaginal Chlamydia infection and the prevalence of the disease in symptomatic gynecologically diseased women in Egypt. In addition, the antibiotics penicillin, tetracycline, and erythromycin were evaluated for their in vitro antichlamydial activity of the isolated strains. Vaginal swabs (n=160) were collected from females gynecologically diseased using cotton swabs.
