Summer mortality syndrome bacterial pathogens in farmed Nile tilapia ().

Background: The high summer mortality in many fish farms, which had detrimental economic and social implications, was a serious challenge that the fish industry had to deal with.

Aim: With an examination of the most effective antibiotic, the ongoing research was intended to shed light on the identification of the main bacterial pathogens associated with the summer mortality syndrome in the diseased farmed Nile tilapia.

Methods: Six hundred dead Nile tilapia samples that had suffered from summer mortality were collected from several fish farms between May and October of 2022.

Transcriptional responses of cytokines, immunoglobulin A, and nitric oxide genes in 1-day-old chicks post infection: An experimental study.

Background: has become one of the hazards prevalent foodborne pathogens causing different diseases in chickens. However, (ST), a nonhost-specific serovar, is a major avian agent that causes severe disturbance in young chicken wellness.

Aim: The occurrence of in chickens and their antimicrobial resistance were explored in this study.

Molecular Characterization and Antimicrobial Susceptibilities of Isolated from Caseous Lymphadenitis of Smallholder Sheep and Goats.

Caseous lymphadenitis (CLA) is a bacterial infection caused by () that affects sheep and goats, leading to abscess formation in their lymph nodes. The present study aimed to isolate and identify from CLA in smallholder sheep and goats, and determine the resistance patterns, virulence, and resistance genes of the isolates. Additionally, genotypic and phylogenetic analysis of the isolates was conducted using ERIC-PCR and DNA sequencing techniques.

Emergence of Colistin and Carbapenem Resistance in Extended-Spectrum β-Lactamase Producing Isolated from Chickens and Humans in Egypt.

This study investigated the frequency of carbapenem and colistin resistance in ESBL-producing (ESBLK) isolates recovered from chickens and their environment, contact farm workers and hospitalized patients in Egypt. Further, the phenotypic and genotypic relationships between the community and hospital-acquired isolates in the same geographical area were investigated. From 272 total samples, 37 (13.

Prevalence, antimicrobial resistance, and genotyping of Shiga toxin-producing Escherichia coli in foods of cattle origin, diarrheic cattle, and diarrheic humans in Egypt.

Shiga toxin-producing Escherichia coli (STEC) is a pathotype of E. coli that causes enteric and systemic diseases ranging from diarrhoea to severe hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS). The emergence of multidrug-resistant (MDR) STEC from cattle sources has increased public health risk and limited treatment options.

Diversity, virulence and antibiogram traits of Escherichia coli recovered from potable water sources in Gharbia, Egypt.

This study aimed to assess the public health risk of coliforms and Escherichia coli contamination of potable water sources in Egypt. A total of 150 water samples (100 tap and 50 well) were collected from five districts in Gharbia governorate, Egypt. High rates of coliforms contamination were recorded in 52 and 76% of examined tap and well water samples, respectively.

Genetic Diversity of Isolated From Avian and Human Sources in Egypt.

() are able to colonise and infect domestic poultry and also pose a risk for humans. The aim of this study was to determine the extent of genotypic diversity among isolates recovered from avian and human sources in Egypt. Furthermore, the short variable region (SVR) of flagellin A () gene was analysed for the presence of allelic variants.

Molecular characterization, antibiotic resistance pattern and biofilm formation of Vibrio parahaemolyticus and V. cholerae isolated from crustaceans and humans.

Human infection with pathogenic vibrios is associated with contaminated seafood consumption. In the present study, we examined 225 crustaceans collected from retail markets in Egypt. Stool samples from gastroenteritis patients were also examined.
