Colibacillosis in calves: A review of literature
Colibacillosis is considered as one of the most important problems faced in livestock production, causing great economic losses. Calves become exposed to pathogenic E. coli in the environment when other infected or carrier calves and cows shed the bacteria in the feces. Diagnosing of E. coli infection in calves depends on an accurate history, clinical signs, culture of internal organs for bacte...
متن کاملAlterations in lipid profile in neonatal calves affected by diarrhea
AIM The aim of this study was to determine the alterations in the lipid profile, plasma alkaline phosphatase (ALP) activity, total and direct bilirubin levels of neonatal calves with diarrhea. MATERIALS AND METHODS A total of 25 calves with diarrhea as experimental group and 10 healthy calves as control group, 1-30 days old, were enrolled in the study. Blood samples were collected from jugula...
متن کاملExperimental neonatal colibacillosis in cows: serological studies.
Serological studies of passive immunity in experimentally induced bovine colibacillosis was studied in a 41-cow university herd. Pregnant dams were antigenized prepartum with two injections administered by the subcutaneous and intrammamary routes with one of four vaccine preparations (killed bacteria, live bacteria, culture supernatant, or heart infusion broth [control]). The data indicate that...
متن کاملPrevention of experimentally induced enteric colibacillosis in newborn calves.
Severe enteric colibacillosis, characterized by profuse watery diarrhea, dehydration, apathy, hypothermia, and inability to stand, was produced in seven of eight newborn, colostrum-fed calves from nonvaccinated dams after oral challenge of calves with 10(11) viable cells of Escherichia coli strain B44. Twenty-nine of 32 calves from dams vaccinated with various preparations of E. coli strain B44...
متن کاملExperimental neonatal colibacillosis in cows: immunoglobin classes involved in protection.
Pregnant cows were vaccinated with one of four vaccine preparations to induce passive immunity in their offspring against a homologous oral challenge with Escherichia coli strain B-44. Quantitative assays of specific antibody in colostral whey from both immunized and nonimmunized dams revealed that immunoglobulin G, immunoglobulin A (IgA), and immunoglobulin M (IgM) with anti-O (somatic) activi...
