five common tetracycline resistance genes tet(a), tet(b), tet(m), tet(o) and tet(s) were studied by polymerase chain reaction in 100 bacteria isolated from iranian fish farms. in the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. nine isolates out of 46 aeromonas spp. contained either tet(a/m/s) resistant genes as follows: tet(a) in a. ...

The use of untreated water for drinking and other activities have been associated with intestinal and extraintestinal infections in humans due to Aeromonas species. In the present study aeromonads were isolated from 48.7% of 1,000 water samples obtained from wells and other miscellaneous sources. Aeromonas species were detected in 45% of samples tested in spring, 34.5% in summer, 48% in autumn ...

Sir, The genus Aeromonas comprises 14 species, although its taxonomy has not yet been resolved. The main species considered to be pathogenic in humans are Aeromonas hydrophila, Aeromonas caviae and Aeromonas veronii biotype sobria. These species can cause both gastrointestinal and extraintestinal infectious diseases. Aeromonas gastroenteritis is generally self-limiting and, except in immunocomp...

Human infection with Aeromonas species is uncommon and most often due to trauma with exposure to contaminated water or soil. A 43-year-old HIV- and hepatitis C virus (HCV)-infected male, after a two-week course of corticosteroid therapy for an autoimmune anemia, developed diarrhea, dermatologic manifestations and a multiple organ dysfunction syndrome, resulting in death. Although stool samples ...

A small subset (n = 18) of highly discriminatory tests was derived from the feature frequency of 50 tests used in the study of 167 predominantly clinical Aeromonas strains. Seven of these eighteen tests were used to construct a flexible, dichotomous key, Aerokey II, for identifying clinical aerontonads: esculin hydrolysis, gas from glucose, acid from arabinose, indole production, acid from sucr...

OBJECTIVE The aim of the present study was to isolate and identify Aeromonas (A.) species and assess their toxin producing ability in foods of animal origin from North East India. MATERIALS AND METHODS A total of 332 animal food samples (fish, poultry meat, pork and chevon) of which 38 (11.44%) isolates were identified by the 16S rRNA technique were included in the study. The enterotoxigenici...

Aeromonads infect human through potable water and causes various infections. Their existence in animal are being assessed as potential risk for human health. The aim of this study was to investigate clonal relationship among 52 Aeromonas strains isolated from human with diarrhea (14 strains), healthy food workers (2 strains), animals (24 strains) and drinking water (12 strains) by pulsed-field ...

Rubber band ligation (RBL) for the treatment of oesophageal varices is a common procedure with low morbidity and mortality. Significant complications such as bacteraemia have been reported in less than 6% of patients treated with RBL for bleeding oesophageal varices. Septic complications following RBL for non-bleeding varices are, however, very rare. Although antibiotic prophylaxis is indicated...
