The title structure, 4-amino-benzoic acid 4-methyl-pyridine/4-methyl-pyridinium 4-amino-benzoate 0.58/0.42, 0.58(C6H7N·C7H7NO2)·0.42(C6H8N+·C7H6NO2-), has been redetermined from the data published by Kumar et al. (2015 ▸). Acta Cryst. E71, o125-o126. The improvement of the present redetermination consists in the introduction of disorder of the methyl group over two positions as well as in the c...

This study was conducted to characterize virulence genes of Escherichia coli isolates from water, sediment, fish, and crab in Aby Lagoon. Serogrouping was performed by EPEC antisera in 113 E. coli strains. The presence of diarrhea-associated genes (eae, stx, AggR, elt, and est) was assessed by multiplex PCR using specific primers. Based on the multiplex PCR, sixty-two isolates (42 from water, 1...

The so called enteropathogenic Escherichia coli (EPEC) O serogroups include typical and atypical EPEC, enterohaemorrragic E. coli, enterotoxigenic E. coli, and enteroaggregative E. coli. The aim of this article is to review the composition of each O serogroup and the major serotypes, clones, and additional virulence characteristics of each of these diarrheagenic categories. Their adherence patt...

background: the purpose of this study was to find out the frequency of different serotypes of enteropathogenic es­cherichia coli (epec) among healthy/diarrheal cases. methods: a total of 191 strains, 111 from diarrheal and 80 from asymptomatic persons were examined. determination of the epec sero­groups was performed by agglutination tests using polyvalent and monovalent o antiserum. pcr-rflp a...

─ Acute urinary tract infections consist of upper urinary tract infections, including pyelonephritis, prostatitis, intra-kidney abscesses, and around-kidney abscesses, and lower urinary tract infections, including urethra infection and bladder infection. These infections can independently or in combination result in irritation in various parts. They may appear as asymptomatic or as one of the c...

Research on the study of parasitocenoses in endometritis and mastitis cows, as well gastrointestinal respiratory diseases newborn calves, were carried out 12 farms Moscow region with a total number 4,445 cows 12,254 cattle. It was found that parasitocenosis cattle are vulnerable to factor infections composed S. agalactiae, dysgalactiae, uberis, pyogenes, pneumoniae, faecalis, aureus, albus, sap...

To evaluate the serogrouping-based diagnosis of diarrheagenic Escherichia coli, a total of 1,130 strains of E. coli isolated in several countries were studied. The strains were regarded as enterovirulent on the basis of their O-antigens determined using a commercially available kit containing 43 antisera, and the presence of diarrhea-associated genes (eae, stx, aggR, est, elt, ipaH) was evaluat...
