Administration of a competitive exclusion culture (CE culture) has the potential to induce protective effects in very young chicks against caecal colonisation by EEC (= extended-spectrum β-lactamases [ESBL] and AmpC-type [AmpC] beta-lactamases producing Escherichia coli).

To investigate a possible transmission of blaCMY-2 along the food production chain, we conducted a nextgeneration sequencing (NGS)-based analysis of 164 CMY-2-producing E. coli isolates from humans, livestock animals and foodstuff from Germany.

The study was aimed to detect the occurrence and characterize extended-spectrum (ESBL) and AmpC (ACBL) beta-lactamases producing pathogenic E. coli (STEC) in diarrhoeal faecal samples collected from bovines. All the E. coli strains (13/21, 61.9%) isolated from bovine diarrhoea cases (n=21) were found to be ESBL producers. In total, 11 (84.6%) isolates were positive in cefoxitin– cloxacillin double-disc synergy (CC-DDS) test for AmpC production and the isolates were also confirmed by PCR for blaAmpC.

Enterobacteriaceae cause protean infections and are the common Gram negative isolates in a microbiology laboratory. Spectrum of multi-drug resistance includes AmpC, Extended spectrum beta lactamase and carbapenemase production with others. This was a cross sectional study to determine susceptibility pattern of AmpC and extended spectrum beta lactamase producing isolates against different antimicrobials.

Increasing drug resistance due to the production of AmpC β-lactamases and Extended spectrum β-lactamases (ESBLs) is an increasing cause of concern as it has left the clinicians with limited therapeutic options. Aims were detection of AmpC β lactamase in E. coli an comparison of the two phenotypic tests- AmpC disk test and Inhibitor based test using phenyl boronic acid. A total of 156 E. coli isolates from various clinical samples were collected for the study.

Acinetobacter the aerobic non fermenting GNCB are emerging as important pathogens in health care associated infection, exhibiting increased antimicrobial resistance by virtue of multiple resistant mechanisms with practically no therapeutic options. The objective was to determine the multitude of resistant mechanisms by phenotypic and genotypic characterization and the prevalent antimicrobial susceptibility pattern. 175 clinically significant non-duplicate Acinetobacter isolates were included.

Extended spectrum β-lactamases are often plasmid mediated and derived from mutations in bla-TEM, bla-SHV, bla-CTX-M, and bla-AmpC genes by one or more amino acid substitution around the active site. These genes are responsible for resistance to beta lactams in Pseudomonas aeruginosa. In this study, Pseudomonas aeruginosa were isolated from wound and burn infection patients admitted to Diwanyia Teaching Hospital.

The aim of this study was to analyze the extended spectrum of β lactamase (ESBL), metallo β lactamase (MBL) and AmpC production in Pseudomonas aeruginosa in various clinical samples. A Total of 100 clinical isolates of P. aeruginosa were collected from different clinical specimen and confirmed by standard tests. Antibiotic susceptibility was determined by the Kirby-Bauer disc diffusion method. ESBL screening was done using 3rd generation cephalosporins and confirmatory combined double disc test, imipenem-EDTA double disc synergy test for MBL enzyme and AmpC test using Cefoxitin disc.

Over the period of years infections caused by multidrug resistance organisms has emerged as a major public health problem. Their prevalence rates vary in different parts of the world and hence local data regarding these pathogens were important. Our study was aimed to identify the presence of ESBL and AmpC producing Enterobacteriaceae isolates from various clinical samples in our hospital setup various clinical samples were processed consecutively during the study period for microbiological analysis as per standard operating procedure.

Ventilator-associated pneumonia (VAP) is an important nosocomial infection in mechanically ventilated patients at intensive care unit (ICU). The administration of accurate and timely initial empirical antibiotic therapy is essential to reduce the morbidity and mortality from Ventilator-associated pneumonia. Initial empiric antimicrobial therapy for VAP greatly depends on the type of causative pathogen and its resistance pattern. During the six months study period, 196 patients received mechanical ventilation.
