Abstract:

Introduction: The treatment options for multi drug resistant (MDR) and extensively drug resistant (XDR) Gram negative bacterial infections are limited. Colistin based combination therapy remains the last option for such infections. The emerging resistance to colistin, especially the transferrable mcr-1 gene mediated resistance poses a global threat. Objectives: This study aims to determine the colistin susceptibility among the multi drug resistant (MDR) clinical isolates of Escherichia coli, Kebsiella pneumoniae and Pseudomonas aeruginosa and also to determine the prevalence of mcr-1 gene in t

Abstract:

AbstractMultidrug resistance (MDR) continues to be a growing global issue. The problem of MDR is fuelled in part by the spread of the genes encoding resistance horizontally which is linked particularly to conjugation involving plasmids. Studies have demonstrated the presence of plasmids in drug resistant isolates, few have shown a link between these plasmids and drug resistance via plasmid curing especially in our locale. This study set out to explore this link inEscherichia coliisolates from Port Harcourt, Nigeria. Plasmid curing was done on a selection of clinical and non-clinical bacteria u

Abstract:

Background Urinary tract infections (UTIs) caused by bacteria occupy the second highest rank of common infectious diseases in the world. Empirical use of antibiotics may give rise to multidrug-resistant (MDR) bacteria because of irrational prescription. Choice of antibiotics to treat UTIs is limited because of MDR bacteria. Thus, this study was conducted to investigate the bacterial antibiotic susceptibility patterns in inpatients and outpatients in Jakarta and Tangerang. Methods Bacterial isolates were obtained from midstream urine specimens from 43 inpatients and 43 outpatients with UTIs in

Most of the Antibiotic Resistance Genes were plasmid determined, so it was, the first attempt to study the effect of curing agent (Ethidium-Bromide ) on Antibiotic Resistance of Uropathogenic E. coli isolates. (106) samples were collected from patients suffering from Urinary Tract Infection (U.T.I.). Samples were implanted on the c

Objectives: This study aims to characterize at the molecular level the genes encoding resistance in Salmonella and explain the molecular mechanisms underlying resistance to ceftriaxone, cefepime, amoxicillin-clavulanate, tetracycline, trimethoprim-sulfamethoxazole, chloramphenicol, colistin and azithromycin in Salmonella. It aims as well to characterize the 16S rRNA gene region by restriction fragment length polymorphism (RFLP) to investigate if this region constitutes an appropriate ‘coincidental’ marker to distinguish important pathogenic Salmonella species. Finally, determine the lineages o

Background: Tuberculosis (TB) accounts for over 40% of all mortality cases from communicable diseases in Europe.Multidrug-resistant TB (MDR-TB) is TB that does not respond to at least isoniazid and rifampicin, the 2 most powerful anti-TB drugs. 30 countries worldwide are classified as high multi drug resistant (MDR) TB burden countries, nine are in the European Region. The emergence of combined resistance to rifampicin and isoniazid (MDR-TB) is a matter of global concern. Methods and Objectives: Over a period of 10 years we examined patient specimens for TB.

Abstract:

Acinetobacter baumannii, a Gram-negative, nosocomial, opportunistic pathogen is commonly infectious in immunocompromised patients. More specifically patients develop healthcare-associated infections (HAI) spanning beyond sepsis, pneumonia, meningitis, and urinary tract infections. Due to its rapid ability to acquire antibiotic resistance, it has raised the necessity to discern a novel therapeutic treatment that can be effectively used against the multidrug resistant (MDR) A. baumannii. Cooper University Hospital (CUH) faced an increased case load of patients that were infected with MDR A. baum

Abstract:

Background: The surge in the prevalence of multidrug-resistant (MDR) Gram-negative bacterial infections with limited treatment options and the decrease in the development of new antibiotics are challenges that lead to the reuse of colistin to treat infections caused by MDR pathogens. This study aimed to determine economical, simple, and reliable colistin susceptibility testing methods as an alternative to the time and effort-consuming microdilution technique and identify the colistin resistance's genetic determinants to find if it affects the testing method.

Abstract:

Carbapenem-resistant Acinetobacter baumannii (CRAB) poses a significant threat to global health, particularly in intensive care units (ICUs). This study investigated the molecular epidemiology and risk factors associated with CRAB infections in four Iraqi ICUs. A total of 164 patients with invasive MDR A. baumannii infections were included. Demographic and clinical data were collected prospectively, and antimicrobial susceptibility testing was performed on 172 isolates (164 clinical and 8 environmental). Multiplex PCR was used to identify four key carbapenem resistance genes. The study reveale

Abstract:

Campylobacter spp. are the most common bacterial cause of foodborne illness in the UK, with chicken considered to be the most important vehicle for this organism. The UK Food Standards Agency (FSA) agreed with industry to reduce Campylobacter spp. contamination in raw chicken and issued a target to reduce the prevalence of the most contaminated chickens (those with more than 1000 cfu per g chicken neck skin) to below 10 % at the end of the slaughter process, initially by 2016. To help monitor progress, a series of UK-wide surveys were undertaken to determine the levels of Campylobacter spp. on

Abstract:

Frozen, breaded, ready-to-cook chicken products have been implicated in outbreaks of salmonellosis. Some of these outbreaks can be large. For example, one outbreak of Salmonella Enteritidis involved 193 people in nine countries between 2018 and 2020, of which 122 cases were in the UK. These ready-to-cook products have a browned, cooked external appearance, which may be perceived as ready-to-eat, leading to mishandling or undercooking by consumers. Continuing concerns about these products led FSA to initiate a short-term (four month), cross-sectional surveillance study undertaken in 2021 to det

Abstract:

Seedless cultivars dominate the table grape industry. In these cultivars it is mandatory to apply gibberellin (GA) to stimulate berry development to a commercially acceptable size. These cultivars differ in their sensitivity to GA application, and it frequently results in adverse effects such as decreased bud fertility and increased fruit drop. Our long term goals are to (1) understand the molecular basis for the differential sensitivity and identify markers for selection of sensitive cultivars (2) to develop new strategies for targeted manipulation of the grape berry response to GA that will
