This study aimed to investigate antibiotics resistance pattern and phenotyping of Aeromonas species isolated from different aquatic sources in Melaka, Malaysia. A total of 53 Aeromonas species were isolated from the following sources: sediment (n = 13), bivalve (n = 10), sea cucumber (n = 16) and sea water (n = 14) and resistance to 12 antibiotics - Tetracycline (30 μg), Kanamycin (30 μg), Oxyt...

SYNOPSIS The influence of medium composition, pH, serum, and magnesium on the action of tobramycin is compared to that on the action of gentamicin. The minimum inhibitory concentration of tobramycin, gentamicin, kanamycin, and streptomycin was determined for 472 strains including 19 species: tobramycin was found to be the most active against Ps. aeruginosa and kanamycin against Providence, but ...

Introduction: Uropathogenic Escherichia coli (UPEC) is among the primary cause of urinary tract infections (UTIs). This study was conducted to determine the antibiotic resistance pattern of E. coli isolates from UTIs in Kermanshah. Methods: In this study, 180 midstream urine samples were collected from outpatients for five months. Based on differential biochemical tests such as oxidase, Indole,...

Naegleria fowleri was causative agent of primary amoebic meningoencephalitis (PAM). Accroding to the failure of treatment, several researches reported the activity of chemotherapeutic drugs against N. fowleri but we did not know the drug resistance of the amoebae. The purpose of this study was to examine the effects of drugs (amphotericin B, artesunate, azithromycin, voriconazole, chlorpromazin...

Background: Multidrug resistance in Salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. Methods: Salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to PCR and identified as Salmonella enteritidis. For detection and ide...

Pseudomonas aeruginosa NCGM1588 has a novel chromosomal class 1 integron, In151, which includes the aac(6')-Iaj gene. The encoded protein, AAC(6')-Iaj, was found to consist of 184 amino acids, with 70% identity to AAC(6')-Ia. Escherichia coli transformed with a plasmid containing the aac(6')-Iaj gene acquired resistance to all aminoglycosides tested except gentamicin. Of note, aac(6')-Iaj contr...

Problem statement: Increased emergence in microbial resistance to antibiotics is a growing problem in Bangladesh, a tropical country with a large agrarian population having limited medical facilities. Wide spread use of antimicrobials in poultry farming here is a concern of multi-drug microbial resistance development that can potentially be transmitted to human pathogens even from non-pathogeni...

BACKGROUND Acinetobacter baumannii plays an important role in some types of nosocomial infections as an opportunist microorganism which increases levels of resistance to antibacterial drugs and disinfectants. OBJECTIVES The aim of this study was to determine the resistance and sensitivity of A. baumannii to different antibiotics and evaluate the minimal inhibitory concentration (MIC) for Cipr...

An outbreak of gentamicin- and tobramycin-resistant Pseudomonas aeruginosa infection occurred in a surgical ward over a three-month period. Resistant Ps. aeruginosa strains with the same serological, phage, and pyocin type were cultured from the urine of six patients. Identical organisms were found on urine bottles, bedpans, and the hands of attendant staff. Inadequate disinfection played a maj...
