In a period of nine months, 225 strains of Gram-negative bacilli isolated from burns were identified by a variety of tests in two burn centers in Tehran. The most common species were Pseudomonas aeruginosa, Pseudomonas fluorescens, Escherichia coli, Enterobacter agglomerans, Enterobacter cloacae and Klebsiella pneumoniae. Many strains of acinetobacter spp, providencia spp, proteus spp, ser...

BACKGROUND The gastric microbiota has recently been implicated in the causation of organic/structural gastroduodenal diseases (gastric and duodenal ulcers, gastric cancer) in patients with Helicobacter pylori (H. pylori) infection. We aimed to ascertain, in patients harbouring H. pylori, the role of the gastric microbiota in the causation of symptoms (chronic dyspepsia) in the absence of organi...

OBJECTIVES To determine the prevalence of class A extended spectrum β-lactamases (ESBL)-producing Escherichia coli and Klebsiella spp., and to investigate clonality among ESBL-producing isolates of nosocomial and community infections. METHODS The study involved 354 nosocomial infections samples and 992 community infections samples, obtained between 2003 and 2006 at Caxias do Sul, RS. The dete...

A total of two hundred and thirteen (213) bacterial isolates were obtained gastrointestinal, urogenital and urinary tract specimens Specialist Hospital and Decent Laboratory in Kofar M The isolates were screened for the production of β method. β-lactamase production w lactamase production among Gram negative and G found to be 141(70.15%) and 5 (41.67%) respectively Haemophilus spp. 1(100%), Sal...

Background Reports of nosocomial infection due to carbapenem resistant Serratia spp. have become significantly more common. This resistance may be due to production of distinct carbapenemases, such as KPC [1,2]. This enzyme, initially described in Klebsiella pneumoniae isolates, has also been detected among other organisms, such as Serratia marcescens, emphasizing the global risk of interspecie...

The objective of this study was to determine the aerobic bacteria and fungi associated with raw camel’s milk. Samples were collected from farms in Bahri (Khartoun North) area in the Sudan. The isolated aerobic bacteria (one hundred and fifteen isolates) were identified as (85.26%) Gram–negative, while (14.73%) were Gram-positive. The Gram-negative bacteria were 39.13% Escherichia coli serotypes...

Successful multidrug-resistant clones are increasing in prevalence globally, which makes the ability to identify these clones urgent. However, adequate, easy-to-perform, and reproducible typing methods are lacking. We investigated whether DiversiLab (DL), an automated repetitive-sequence-based PCR bacterial typing system (bioMérieux), is suitable for comparing isolates analyzed at different geo...

The species of total coliform bacteria isolated from drinking water and untreated surface water by the membrane filter (MF), the standard most-probable-number (S-MPN), and modified most-probable-number (M-MPN) techniques were compared. Each coliform detection technique selected for a different profile of coliform species from both types of water samples. The MF technique indicated that Citrobac...

U-76,252 is the prodrug of U-76,253. MICs of U-76,253 were 0.015 to 0.06 microgram/ml for greater than or equal to 90% of the strains of Streptococcus spp., Haemophilus influenzae, and Proteus mirabilis; 0.25 to 1 microgram/ml for Branhamella catarrhalis, Escherichia coli, Klebsiella spp., and Citrobacter diversus; 1 to 8 micrograms/ml for Staphylococcus spp.; and 2 to greater than 16 microgram...
