Aeromonas spp. are among the most ubiquitous microorganisms, as they have been isolated from different environmental niches including waters, soil, as well as wounds and digestive tracts of poikilothermic animals and humans. Although much attention has been paid to the pathogenicity of Aeromonads, the role of these bacteria in environmentally important processes, such as transformation of heavy...

BACKGROUND Not all patients infected with NDM-1-positive bacteria have a history of hospital admission in India, and extended-spectrum β-lactamases are known to be circulating in the Indian community. We therefore measured the prevalence of the NDM-1 gene in drinking water and seepage samples in New Delhi. METHODS Swabs absorbing about 100 μL of seepage water (ie, water pools in streets or ri...

Abstract: This study was conducted to investigate the prevalence, antimicrobial susceptibility, and molecular characterization of Aeromonas spp. from wild Nile tilapia Lake Manzala lake water. Swabs surface, gills, internal organs apparently healthy (n =100) water = 25) were collected examined bacteriologically for presence The isolates obtained tested their susceptibility 11 agents using disk ...

Aeromonas spp. are autochthonous in the aquatic ecosystem and some of them has been increasingly found, in patients with various diseases like enteritis, wound infection and even septicemia in amphibians, reptiles, frog, fish and in patients with impaired immunity. There are different virulence factors like aerolysin, hemolysins, cytotoxins, enterotoxins, proteolytic activity, lipolytic activit...

About 30% poultry samples harboured Aeromonas spp. Sensitivity tests of 100 selected strains against 12 antibiotics revealed that 20 100% were resistant to nine and 18 85% were sensitive to eight antibiotics, respectively. All isolates showed multiple resistance to six to nine antibiotics and thus pose a risk for both chicken farms and public health. Aeromonads are major causative agents of inf...

The genus Enterobacter was first proposed by Hormaeche and Edwards (1960a). However, the history of some species now placed in the genus Enterobacter can be traced, albeit with some confusion, to the end of the 19th century. “Bacillus lactis aerogenes” was isolated by Escherich (1885) from milk and renamed “Bacillus aerogenes” by Kruse (1896) and “Aerobacter aerogenes” by Beijerinck (1900). Unt...

(a) Project Summary Fishery has been recognized as a powerful income and employment generation source as it stimulates growth of a number of subsidiary industries and is a source of cheap animal protein. Fish diseases, however, are one of the major limiting factors in aquaculture production, especially with the recent increase of aquaculture practices in rural areas. Rural small-scale aquacultu...

Bacteria that are essentially polar flagellate, either monotrichous or multitrichous, may develop lateral flagella as well. These lateral flagella invariably have a shorter wavelength than the polar flagella. If this were not so, the organism could not readily be differentiated from the usual peritrichous types. The wavelength of the lateral flagella is generally about 1 ,u, regardless of the w...

This report describes the isolation of Aeromonas veronii biovar sobria as the causative enteropathogen of diarrhoea in an oncological patient after failure of detection of other infectious agents. The case points out the severe and long course of the infection, the diagnostic dilemma, and the prompt recovery after antibiotic treatment. K e y w o r d s: Aeromonas veronii, diarrhoea, foodborne pa...

In this study, molecular characterization of antimicrobial resistance of 116 Yersinia ruckeri strains isolated from rainbow trout (Oncorhynchus mykiss) with enteric redmouth disease (ERM) in commercial fish farms in the Northern and Eastern regions of Turkey was performed. The putative Y. ruckeri strains isolated were confirmed by PCR assays specific to the 16S rRNA gene of bacterium Y. ruckeri...
