Low blood 2 calcium often occurs in older cows around calving and impairs subsequent health and milk yield. 3 Second lactation or greater cows in 2 commercial dairies with effective milk fever prevention 4 were divided into contro...
coxiella burnetii is the causative agent of the zoonotic disease q fever, and ruminants being considered as the main source for human infection. although the main route of infection in human is inhalation of contaminated aerosols, oral transmission by contaminated raw milk or unpasteurized dairy products is also a possible route of infection. raw milk or dairy products produced from unpasteuriz...
The effect of seven diseases on culling was measured in 7523 Holstein cows in New York State. The cows were from 14 herds and had calved between January 1, 1994 and December 31, 1994; all cows were followed until September 30, 1995. Survival analysis was performed using the Cox proportional hazards model to incorporate time-dependent covariates for diseases. Different intervals representing sta...
Coxiella burnetii isolates from a variety of clinical and geographical sources were screened for antigenic variation of lipopolysaccharides (LPSs) by sodium dodecyl sulfate-polyacrylamide gel electrophoresis coupled with silver staining or immunoblotting. All isolates from chronic Q fever or other sources possessed a phase I-type LPS. These LPSs appeared to fall into three groups based on the s...
BACKGROUND Antenatal immunization of mothers with influenza vaccine increases serum antibodies and reduces the rates of influenza illness in mothers and their infants. We report the effect of antenatal immunization on the levels of specific anti-influenza IgA levels in human breast milk. (ClinicalTrials.gov identifier NCT00142389; http://clinicaltrials.gov/ct2/show/NCT00142389). METHODS AND F...
Background: Q fever is a widespread zoonotic disease that is caused by obligate intracellular bacteria, Coxiella burnetii. Raw milk or dairy products that are produced from unpasteurized milk may contain virulent Coxiella burnetii. The objective of this study was to determine the prevalence rate of C. burnetii in raw and unpasteurized cow bulk tank milk samples of traditional domestic dairy pro...

Background With more than 500,000 new cases annually, human brucellosis is the commonest zoonotic disease worldwide. In some endemic countries, its prevalence is more than 10 per 100,000 population. Objective The aim of this study was to determine the magnitude of the problem and the clinical features, laboratory findings, treatment given and complications seen in children with brucellosis in...
