Survival of Clostridium difficile in an aerobic environment is possible because of spore formation. When sodium taurocholate is substituted for the egg yolk of a selective medium, cycloserine-cefoxitin-fructose-agar (CCFA), enhanced recovery of C. difficile spores is shown. This selective medium (TCCFA) does not improve recovery of vegetative forms. In this study, dry and saline-moistened swabs...

Mycoplasma synoviae (M. synoviae) is a major worldwide poultry pathogen that causes serious economic losses in the poultry industry. This study was designed to detect M. synoviae through culture isolation and polymerase chain reaction (PCR) assay to demonstrated the involvement of M. synoviae infection in trachea and the lung/air sac samples taken from commercial broiler chicken farms in 3 m...

INTRODUCTION Approximately 10-40% of all the nosocomial infections are pulmonary, which lead to grave complications. Elderly, debilitated, or critically ill patients are at a high risk. The respiratory care equipments which include ventilators, humidifiers, nebulizers may have been identified as the potential vehicles which cause major nosocomial infections if they are colonized by fungi or bac...

In response to a bioterrorism attack in the Washington, D.C., area in October 2001, a mobile laboratory (ML) was set up in the city to conduct rapid molecular tests on environmental samples for the presence of Bacillus anthracis spores and to route samples for further culture analysis. The ML contained class I laminar-flow hoods, a portable autoclave, two portable real-time PCR devices (Ruggedi...

Hatchery contamination can result in ingested or inhaled microbes that may modify colonization of the intestinal and respiratory tract, with potential to influence early growth, inflammation, overall health. Six experiments were completed compare chick quality, health between two hatcheries (H1 H2). On embryonic d0, 45 eggs from same breeder flock set at each hatchery. length, abdominal height,...

The Gen-Probe Group A Streptococcus Direct Test (GASDT), which detects the presence or absence of group A streptococci directly from pharyngeal specimens, utilizes a specific relative light unit (RLU) cutoff of 4,500 to differentiate between positive and negative test results. In response to a report by a manufacturer that the background RLU values for the Copan rayon swabs with liquid media we...

The current study described the isolation and molecular detection of Mycoplasma gallisepticum (Mg) and Mycoplasma synoviae from tracheal swabs of diseased birds showing signs of respiratory distress in selected commercial (layer and broiler) farms and from yolk and an open air of pens of vaccinated breeder flocks in Sudan. A number of 45 Mycoplasma isolates were recovered from chickens in Khart...
