Optical maps were generated for 33 uropathogenic Escherichia coli (UPEC) isolates. For individual genomes, the NcoI restriction fragments aligned into a unique chromosome map for each individual isolate, which was then compared with the in silico restriction maps of all of the sequenced E. coli and Shigella strains. All of the UPEC isolates clustered separately from the Shigella strains as well...

Background and Objective: Biofilm formation plays a crucial role in wound infections and increases the bacteria resistance to treatment. The present study investigated the relationship between the biofilm formation, ESBL, AmpC, and KPC enzymes in Acinetobacter baumannii isolated from the wound specimens. Materials and Methods: Eighty- nine A. baumannii isolates were collected from wound specim...

Bacterial diarrheal diseases cause substantial morbidity and mortality in sub-Saharan Africa, but data on the epidemiology and antimicrobial susceptibility patterns of enteric bacterial pathogens are limited. Between May 1997 and April 1998, a clinic-based surveillance for diarrheal disease was conducted in Asembo, a rural area in western Kenya. In total, 729 diarrheal specimens were collected,...

fertility status and distribution of mating type alleles of gibberella moniliformis and g. intermedia, both the causal agents of the foot rot and bakanae of rice, as well as stalk and root rot of corn were studied using specific primers. one hundred and twenty eight single-spore isolates were collected from rice growing areas of guilan and mazandaran and from various corn-growing areas of iran....

Salmonella enterica causes health problem worldwide. The relationships among strains that are from the same serotype but different hosts, countries, and continents remain elusive. Few genome sequences are available from S. enterica isolates from South America. Therefore, we sequenced the genomes of 33 strains from diverse sources isolated in Chile and determined that they were of different sero...

BACKGROUND Biosurfactants are surface-active compounds produced by some microorganisms. OBJECTIVES In this study, we collected surface skin samples from breast of poultry (chicken, turkey, and, quail) and screened for biosurfactant-producing bacteria. We also determined the genera of cultured strains. MATERIALS AND METHODS 33 hemolytic bacterial strains (15, 11, and 7 isolates from chicken,...

The adhesin pertactin (Prn) is one of the major virulence factors of Bordetella pertussis, the etiological agent of whooping cough. However, a significant prevalence of Prn-deficient (Prn(-)) B. pertussis was observed in Japan. The Prn(-) isolate was first discovered in 1997, and 33 (27%) Prn(-) isolates were identified among 121 B. pertussis isolates collected from 1990 to 2009. Sequence analy...

A total of 111 Pasteurella multocida isolates recovered from healthy and diseased rabbits were typed for capsular and somatic antigens by the typing systems of Carter and Heddleston, respectively. The major serotypes of the 48 P. multocida isolates recovered from nasal cavities of healthy rabbits were serotypes 12:A (33%), nontypable:A (50%), and nontypable:D (10%). Similarly, the major serotyp...

Background: Milk is a reservoir for several groups of microorganisms, which may pose health risks. The aim of this work was to assess the antibiotic resistance and biofilm production in catalase-positive Gram-positive cocci isolated from Brazilian pasteurized milk. Methods: The bacteria were isolated using Baird-Parker agar and identified by Matrix-Assisted Laser Desorption/Ionization-Time-Of-...
