Abstract:

Food is essential for the survival of man and animals in the planet but this necessity sometimes becomes the means of destruction from the planet. Most infections that man get are either from food or water. In the last 20 years there have been several cases of food borne pathogens causing deleterious infections in man and animals. Some of these pathogens are just newly emerging and not much has been studied on them until recent times. The bulk of pathogens of food are of bacterial origin. In this review we looked at current trends in emerging food pathogens globally as it concerns the health o

Abstract:

Abstract Microorganisms adopt a unique mechanism for sequestration and transport of bound iron by producing iron-chelating molecules called siderophores. Siderophores play an important role in colonization of microbes in iron-deficient sites of the host, hence acting as an important virulence factor and promising carriers of antimicrobials to target sites inside the microbial cells. The research was conducted to identify and characterize the siderophores of pathogenic Escherichia coli isolates obtained from different parts of India. A total of 534 confirmed E. coli isolates were tested for the

The presence of Ha-NhaD conferred tolerance of E. coli KNabc to NaCl up to 0.6 mol·L–1 and to LiCl up to 0.2 mol·L–1 and to an alkaline pH. pH-dependent Na+(Li+)/H+ antiport activity was detected from everted membrane vesicles prepared from E. coli KNabc/pUC-nhaD but not those of KNabc/pUC18.

Food is universal to man as well as animals which also provide a bulk of the food needed by man. The current population of the world stands at about 7 billion. With this increasing population is also the increasing need to provide not just food but also healthy food for the consumption of man. In this paper we examine the integrated approach to food safety in order to meet the need for healthy food by man and in a healthy manner to all the occupants of the planet whether plants or animals.

SUMMARY A comprehensive study of 223 Escherichia coli isolates from pigs with colibacillosis included determination of O serogroups, detection of heat-labile enterotoxin, heat-stable enterotoxin (STa and STb), and identification of K88, K99, 987-P, F-41, and type 1 fimbriae. The incidence of the various E coli types among isolates of pigs of different ages was also determined. Escherichia coli bearing K88 fimbriae accounted for 48% of all isolates studied, were most often of serogroup 0157, 0149, or 08, and usually produced labile toxin alone or in combination with STa or STb.

Enteric disorders are related with the fimbriae F4 (K88), F5 (K99), F6 (987P), F41, and F18. In addition to ETEC, another category of E. coli , porcine pathogenic E. coli (PEPEC),can cause diarrhea in pigs; it produces the porcine attaching and effacing-associated (Paa) adhesin in, which is capable to cause a typical lesion known

Abstract:

This study evaluated the antimicrobial activity of a Ricinus communis-based experimental dentifrice for denture hygiene against the following standard strains: Staphylococcus aureus, Escherichia coli, Streptococcus mutans, Enterococcus faecalis, Candida albicans and Candida glabrata. The minimum inhibitory concentration (MIC) assay was performed with R. communis in pure oil at 2.5%. Only E. coli was not inhibited by R. communis, but the MIC (0.0781%) was effective against the other microorganisms. From these results it was determined the R. communis concentrations for experimental dentifrices,

Abstract The present study aimed to compare the effectiveness of QMiX and 17% EDTA associated to passive ultrasonic irrigation (PUI) or manual agitation (MA) on the reduction of E. faecalis, E. coli and LPS from root canals. Forty single rooted human teeth were randomly divided into four groups (n=10), according to the final irrigation protocol: EDTA+MA, QMiX+MA, EDTA+PUI, QMiX+PUI. Sample collections were obtained from the root canal content immediately before preparation (baseline-S1), after instrumentation (S2), after final irrigation protocol (S3) and 7 days after instrumentation and final

Abstract:

ABSTRACTEnteropathogenicEscherichia coli(EPEC) and enterohemorrhagicE. coli(EHEC) are related attaching and effacing (A/E) pathogens. The genes responsible for the A/E pathology are carried on a chromosomal pathogenicity island termed the locus of enterocyte effacement (LEE). Both pathogens share a high degree of homology in the LEE and additional O islands. EHEC prevalence is much lower in areas where EPEC is endemic. This may be due to the development of antibodies against common EPEC and EHEC antigens. This study investigated the hypothesis that EPEC infections may protect against EHEC infe

Resumo O teste a frio (Cold Test) é um processo inovador no Brasil com relação aos testes em motores diesel. Esse processo foi implementado em uma empresa fabricante de motores diesel, com o intuito de ser o principal teste de validação antes de os motores serem enviados ao cliente. Partindo-se dessa hipótese, surgiu o principal motivo desta investigação: é possível a substituição plena do teste a quente (Hot Test) pelo teste a frio (Cold Test)? Essa foi uma pergunta impactante, visto que o Hot Test é um processo confiável e consagrado há mais de 18 anos. O método utilizado nesta pesquisa foi

Abstract Introduction Evening and nocturnal exposure to cold and warm temperature can respectively blunt or enhance vasodilation needed to initiate sleep. However, the effects of temperature exposure several hours prior to bedtime on sleep have not been well studied.

Abstract:

ABSTRACT Escherichia coli O157:H7 is a food-borne pathogen causing hemorrhagic colitis and hemolytic-uremic syndrome, especially in children. The main virulence factor responsible for the more serious disease is the Shiga toxin 2 (Stx2), which is released in the gut after oral ingestion of the organism. Although it is accepted that the amount of Stx2 produced by E. coli O157:H7 in the gut is critical for the development of disease, the eukaryotic or prokaryotic gut factors that modulate Stx2 synthesis are largely unknown. In this study, we examined the influence of prokaryotic molecules releas

A morte do socialismo de Estado não determina necessariamente um futuro de infortúnios para esse grupo de países, inclusive o Brasil. Alguns países do “Sul” escapam de um destino obscuro, mas outros não, dependendo da competência de suas elites e de suas forças políticas para definir e implementar um projeto de desenvolvimento nacional. Este artigo trata do contexto em que o Brasil e a América Latina estão após a Guerra Fria.

Abstract:

Abstract The aim of this study was the expression of goose parvovirus capsid protein (VP3) and its epitopes in Escherichia coli cells. Expression of the whole VP3 protein provided an insufficient amount of protein. In contrast, the expression of two VP3 epitopes (VP3ep4, VP3ep6) in E. coli, resulted in very high expression levels. This may suggest that smaller parts of the GPV antigenic determinants are more efficiently expressed than the complete VP3 gene.

In fact, maximal renal toxicity of aminoglycosides was observed when the drug was given during the rest period, while a lower toxicity was observed when the drug was injected during the activity period. The aim of the present study was to evaluate temporal variations in the effectiveness and renal toxicity of gentamicin in an experimental model of pyelonephritis in rats.
