Enterohemorrhagic Escherichia coli O157:H7 is an important intestinal pathogen of humans with a main reservoir of domesticated ruminants, particularly cattle. It is anticipated that the risk of human infection can be reduced by controlling the organism within its reservoir hosts. Several options for the control of E. coli O157:H7 in cattle have been proposed, but none have been demonstrated to ...
From November 2011 through March 2012, we surveyed 272 babies in our neonatal intensive care unit for rectal colonization with vancomycin-resistant enterococci (VRE). Using Spectra VRE medium (Remel Diagnostics, Lenexa, KS), we identified one neonate colonized with vancomycin-resistant Enterococcus faecium. In addition, 55 (13%) of the surveillance cultures yielded false-positive results with v...
INTRODUCTION In contrast to industrialized countries, until recently Group B Streptococcus (GBS) was infrequently reported in the developing world. This study was aimed at investigating the prevalence of GBS maternal colonization and to analyze the serotype distribution among the isolates. METHODS Vagino-rectal swabs collected from pregnant women were cultured for GBS using conventional media...
Rapid and accurate identification of carriers of resistant microorganisms is an important aspect of efficient infection control in hospitals. Traditional identification methods of antibiotic-resistant bacteria usually take at least 3 to 4 days after sampling. A duplex real-time PCR assay was developed for rapid detection of ampicillin-resistant Enterococcus faecium (ARE). Primers and probes tha...
Campylobacter cinaedi and C. fennelliae have been associated with proctocolitis, bacteremia, and asymptomatic rectal infection, primarily in homosexual men. To more directly assess the pathogenic role of these organisms, we studied their disease-producing potential in 12- to 25-day-old pig-tailed macaques (Macaca nemestrina). Four infant monkeys were challenged with 10(8) to 10(9) C. cinaedi, t...
cutaneous metastases of rectal carcinoma is a rare event. it occurs in fewer than 4% of all patients with rectal cancer. when present, it typically signifies a disseminated disease with a poor prognosis. early detection and proper diagnosis of metastatic rectal cancer can significantly alter treatment and prognosis. we report a 70-year-old male who underwent rectal resection with permanent colo...
OBJECTIVES To describe the investigation and molecular characterization of a vancomycin-resistant Enterococcus faecium (VREF) strain responsible for a nosocomial outbreak in the haematology unit of a tertiary-care university hospital. PATIENTS AND METHODS Two patients admitted to the haematology unit developed infection/colonization with VREF over a 3 month period when compared with none in t...
OBJECTIVE Vancomycin resistant enterococci (VRE) colonization and the spread decrease with compliance and isolation guidelines. For the isolation methods to succeed, compliance with the isolation guidelines needs to be overseen. In this study, VRE outbreak among the Pediatric Ward patients, the preventative efforts to control this outbreak, and the impact of scoring tables used in controlling t...
background: radiotherapy is one of the most important factors which results in negative effects on wound healing and increases anastomosis leakage. diverting loop ileostomy has been usually performed after colorectal anastomosis in cases of colorectal cancer with a history of neoadjuvant radiotherapy to decrease the chance of leakage. considering the side effects of diverting loop ileostomy, th...
inflammatory bowel diseases are one of the important reasons of the referral to gi practitioners in our country and ulcerative colitis is the more frequent type of these disease in iran. in this study 200 cases of ulcerative colitis, which has been referred to imam khomeini hospital during that last 5 year, were studied. data was collected using the patient's records and face to face inter...
