Effect of dry period immunization of Salmonella Dublin latent carriers with a commercial live culture vaccine on intrauterine transmission based on the presence of precolostral antibodies in offspring.

Salmonella Dublin latent carrier cows represent a high risk for infection of newborn calves via intrauterine transmission and shedding of bacteria in feces and colostrum at calving. Vaccination of these latent carrier dams during late gestation boosts immunity against Salmonella Dublin. This could reduce the activation of the dormant bacteria during the periparturient immune dysfunction period, thereby reducing the risk of early-life infection in the offspring.

Review: Dublin in dairy cattle.

serovar Dublin (. Dublin) is a bacterium host-adapted to cattle with increasing prevalence in dairy facilities. It can severely affect cattle health, producing high morbidity and mortality in young calves and reducing the performance of mature animals.

Gene Expression of Aquaporins (AQPs) in Cumulus Oocytes Complex and Embryo of Cattle.

Aquaporins () are proteins with various functions related to proper cell function and early development in mammals. The aim of this study was to evaluate the presence of and determine their mRNA levels in the cumulus oocyte complex (COC) of four bovine breeds and in blastocysts of five bovine crosses. Grade I, II and III COCs were collected by ovum pick up from non-lactating heifers of the Brahaman, Holstein, Gir and Romosinuano breeds.

Molecular identification of fluoroquinolone resistance in spp. isolated from broiler farms and human samples obtained from two regions in Colombia.

Background And Aim: is one of the most common foodborne pathogens, the emergence of antibiotic-resistant strains of which is increasing. The aim of this study was to phenotypically and genotypically characterize the fluoroquinolone resistance of isolates from broiler and humans in two regions of Colombia.

Materials And Methods: strains (n49) were evaluated.

Antibiotic resistance in spp. isolated from poultry: A global overview.

is the most important foodborne pathogen, and it is often associated with the contamination of poultry products. Annually, causes around 93 million cases of gastroenteritis and 155,000 deaths worldwide. Antimicrobial therapy is the first choice of treatment for this bacterial infection; however, antimicrobial resistance has become a problem due to the misuse of antibiotics both in human medicine and animal production.
