With the universal adoption of antibiotic prophylaxis prior to prostate biopsy, the current risk of post-biopsy infection (including sepsis) is <2%. Preoperative prophylactic antibiotic regimens can vary, and although fluoroquinolones have emerged as the standard of care, there is no universally agreed upon preoperative antibiotic regimen. Recently, an increase in the proportion of postoperativ...

In this study, the intestinal bacteria of wild Antarctic fish (family Nototheniidae) were examined using traditional culture-based techniques. Bacterial flora of the gut contents of four marine fish species (Notothenia coriiceps, Trematomus bernacchii, Trematomus hansoni, and Trematomus newnesi) was investigated to describe the allochthonous bacteria inhabiting these Nototheniidae fish. A set o...

Many pathogens are capable of causing a fulminant infection in pulmonary tissues of mammals. Animal models have provided an extensive understanding of the genetic and molecular mechanisms of bacterial pathogenesis as well as host immune response in the lungs. Many clinically relevant Gram-negative bacteria are host-restricted. Thus, the powerful, informative tools of mouse models are not availa...

Interdisciplinary scientific evaluation of the human microbiota has identified three enteric microbial biotransformations of particular relevance for human health and well-being, especially cancer. Two biotransformations are counterproductive; one is productive. First, selective bacteria can reverse beneficial hepatic hydroxylation to produce toxic secondary bile acids, especially deoxycholic a...

We have previously shown that antibodies raised in rabbits to certain enteric bacteria will specifically lyse, in a 51Cr release assay, the peripheral blood lymphocytes (PBL) of 80% of HLA-B27 positive patients with ankylosing spondylitis (B27+ AS+) but not the PBL of HLA-B27 positive normal controls (B27+ AS-). Other laboratories have been unable to reproduce these findings. This study was des...

The nucleotide sequences, genetic organization, and distribution of plasmids pEU30 (30,314 bp) and pEL60 (60,145 bp) from the plant pathogen Erwinia amylovora are described. The newly characterized pEU30 and pEL60 plasmids inhabited strains isolated in the western United States and Lebanon, respectively. The gene content of pEU30 resembled plasmids found in plant-associated bacteria, while that...

BACKGROUND Surgical site infection remains a significant problem, and peri-operative strategies to reduce wound exposure to bacteria are needed urgently. Plastic ring wound retractors, used to gain access to the abdominal cavity, may shield the incision site from bacteria. AIM To evaluate exposure of the surgical incision site to bacteria using a plastic ring wound retractor in gastrointestin...

in recent years due to changes in lifestyle and eating behavior of the human populations, disease caused by contaminated food has increased significantly. listeria monocytogenes, escherichia coli o157:h7 and salmonella enteric are three of the most important food borne bacterial pathogens and can lead to food borne diseases. also today wide spread of resistance to antibiotics among bacteria occ...

BACKGROUND No studies so far have examined enteric infections in patients undergoing bone marrow transplantation (BMT) in developing countries where asymptomatic carriage and colonization with enteric pathogens is frequent. METHODS A prospective study followed 65 patients who underwent BMT in South India between 1995 and 1998. Patients were screened for enteric pathogens before transplantatio...
