Abstract:

Dysbiosis is a pathological condition caused by violating the normal coexistence of bacterial organisms in one or more body systems. This disease arises due to the action of many ethological factors, the mechanisms of which arise from each other. Klebsiellosis of bee colonies is a relatively new disease of Apis mellifera, caused by pathogenic enterobacteria, which leads to the mass death of bees with signs of acute dyspepsia, particularly in the spring and autumn periods. To prevent klebsiellosis in bees, it is necessary to carry out veterinary and sanitary measures in apiaries every year, inc

In farm animals, the amount of transient pathogenic enterobacteria Salmonella enteritidis and Yersinia enterocolitica did not exceed 0.22-0.12%. Among wild animals, the proportion of pathogenic Salmonella enteritidis and Yersinia enterocolitica did not exceed 0.24-0.11%, while Shigella dysenteriae and Shigella flexneri were isolated

Abstract:

The present investigation has been carried out to assess the microbial safety and pathogenic potentialities of enterobacteria in poultry feeds. From the results it was observed that total aerobic plate count of poultry feeds samples were recorded as 2.8 × 105 to 5.8 × 109 cfu/g and 100% samples contained ≥106 cfu/g while the highest mean of cfu was counted as log10 8.797/gm. Large number of coliforms were recorded in different poultry feed samples and the ranges of cfu were counted as 1.2 × 104 to 5.2 × 107/g while average 75% samples were contaminated with coliform bacteria with ≥104 cfu/g an

Abstract:

To investigate the inhibitory effect of indigenous enterobacteria on pathogenic Escherichia coli, a challenge trial with postweaning pigs was conducted. A pathogenic E. coli strain was administered to all animals and their health was closely monitored thereafter. Faecal samples were taken from three healthy and three diarrhoeic animals. Samples were cultivated on MacConkey agar and isolates were subcultured. A soft agar overlay assay was used to determine the inhibitory activity of the isolates. A total of 1,173 enterobacterial isolates were screened for their ability to inhibit the E. coli ch

Opportunistic bacteria are the cause of many animal diseases. Infections caused by them have a prolonged character, the pathogenetic basis of which is the persistence of the pathogen in the host body. Bacterial exotoxins damage the plasma membrane of cells.

Abstract:

The evaluation of workers as potential reservoirs and disseminators of pathogenic bacteria has been described as a strategy for the prevention and control of healthcare-associated infections (HAIs). The aim of this study was to evaluate the presence of Enterobacteriaceae in the oral cavity of workers at an oncology hospital in the Midwest region of Brazil, as well as to characterize the phenotypic profile of the isolates. Saliva samples of 294 workers from the hospital’s healthcare and support teams were collected. Microbiological procedures were performed according to standard techniques. Amo

Out of the 120 studied birds, 60 belonged to the test group and 60 to the control group. At 1, 7, 12, 18, 23 and 28 days of age, the chickens and rations were weighed and mortality and morbidity were determined. Then, the birds were sacrificed and the pH of the crop content was measured, ileum fragments were collected for morphometric analysis and the enterobacteria in the ceca

The research was carried out during the years 2011-2022 in PHMI TMA Buiucani, 12496 samples were processed and 129 strains (1.03%) were isolated. The major causative agents of acute diarrheal disease were pathogenic enterobacteria Salmonella spp. (90.7%) and Shigella spp. (9.3%). The dominant serovars were Salmonella Enteritidis (53.49%) and S. Typhimurium (37.21%), and Shigella serogroups constituted 4.65% each. The isolation rate of Salmonella and Shigella strains decreased ranging from 1.67% (year 2011) to 0.12% (year 2022), except for 2014 (2.01%) and 2015 (1.78%). To mitigate acute bacter

Probiotic Escherichia coli Nissle 1917 (EcN) possesses excellent antibacterial effects on pathogenic enterobacteria. The microcins MccM and MccH47 produced in EcN played critical roles, but they are understudied and poorly characterized, and the individual antibacterial mechanisms are still unclear. In this study, three EcN mutants (ΔmcmA, ΔmchB, and ΔmcmAΔmchB) were constructed and compared with wild-type EcN (EcN wt) to test for inhibitory effects on the growth of Escherichia coli O157: H7, Salmonella enterica (SE), and Salmonella typhimurium (ST).

Tap outlets have been found to contain biofilms, which are a consortium of bacteria, fungi, viruses and protozoa. These microorganisms, especially Gram negative bacteria, could be pathogenic and highly resistant to antibiotics, leading to an increase in the prevalence of diseases worldwide. The university community depends on water from boreholes for consumption and domestic uses; as such, the need to identify the Gram negative bacteria is expedient. The main objective of this research is to determine the potability of the water released from the taps, and ultimately reduce the incidence of bi

In the present study, we describe protein film voltammetry in which the activity of E. coli cytochrome c nitrite reductase is challenged by the presence of a number of small molecules. These results are discussed in light of the environment(s) that the enzyme may face before and after colonization of a hum
