Staphylococcus Pseudintermedius: Population Genetics And Antimicrobial Resistance, Ricardo Videla

Masters Theses

Staphylococcus pseudintermedius is a Gram-positive coagulase-negative coccus. It is a normal inhabitant of the skin of dogs. However, clinical disease can be observed in animals that are immunossuppressed or if the skin barrier is altered. This bacterium is recognized as the main cause of canine pyoderma and has also been associated with other conditions such as infection of the urinary tract, the ears, and surgical wounds.

Methicillin resistance and resistance to other antimicrobials regularly used by veterinarians is common among S. pseudintermedius which can complicate treatment. The first report of mecA, gene responsible for methicillin resistance, in S. pseudintermedius …

Efficacy Of Selected Disinfectants Against Salmonella Isolates From Broiler Breeders, Arslan Aslam

Graduate Theses and Dissertations

Salmonella have been causing huge losses in the poultry industry and have been a major cause food borne illness for many years. Salmonella infections in humans from poultry have been increasing. Good hygiene and biosecurity measures can reduce the incidence of Salmonella infections at poultry farms. Disinfection is a most important measure taken to prevent Salmonellosis in poultry. This research was conducted to determine the efficacy of 12 disinfectants against seven Salmonella isolates in the presence and absence of organic matter. A bacterial solution of a specific optical density value was prepared and .05x, .1x and .2x concentrations of disinfectants …

Determination Of Farm-Specific Lawsonia Intracellularis Seroprevalence In Central Kentucky Thoroughbreds And The Identification Of Factors Contributing To Equine Proliferative Enteropathy, Allen E. Page

Theses and Dissertations--Veterinary Science

Lawsonia intracellularis and the disease it causes in horses, equine proliferative enteropathy (EPE), is an emerging pathogen of increasing importance to the horse industry from both an economic and welfare standpoint. Long recognized as an economically important disease of swine, the hallmark of EPE is a protein-losing enteropathy, where affected horses suffer weight loss and some ultimately succumb to the disease despite aggressive treatment. There are currently no known EPE preventative measures and the epidemiology of the disease remains poorly defined. While EPE is a sporadic disease affecting less than 25% of exposed horses, some farms experience clinical cases year …
