Article Synopsis
- - Biofloc (BF) shrimp farming shows promise for sustainability, but optimizing conditions like density and feeding is essential for its success.
- - A study comparing low density (LD) and high density (HD) stocking of white-leg shrimp revealed that shrimp in the LD group had better growth rates, survival, and protein content, while the HD group had higher harmful bacterial counts.
- - Immune gene expression was notably higher in the LD group, suggesting better health, whereas the HD group showed increased stress markers, emphasizing the need for careful management of shrimp farming densities.
Prevalence of multidrug resistance Salmonella species isolated from clinical specimens at University of Gondar comprehensive specialized hospital Northwest Ethiopia: A retrospective study.

Department of Immunology and Molecular Biology, School of Biomedical and Laboratory Sciences, College of Medicine and Health Sciences, University of Gondar, Gondar, Ethiopia.
Background: Multidrug resistance Salmonellosis remains an important public health problem globally. The disease is among the leading causes of morbidity and mortality in developing countries, but there have been limited recent studies about the prevalence, antimicrobial resistance, and multidrug resistance patterns of Salmonella isolates from various clinical specimens.
Objective: Aimed to assess the prevalence, antimicrobial resistance, and multidrug resistance patterns of Salmonella isolates from clinical specimens at the University of Gondar Comprehensive Specialised Hospital, northwestern Ethiopia.
Isolation and identification of multidrug resistance bacterial agents implicated in duck enteritis with first record of subspecies arizonae in Egypt.
Open Vet J
January 2024
Faculty of Veterinary Medicine, Veterinary Hospital, Zagazig, Egypt.
Background: Bacterial infections causing digestive problems are among the most serious threats to Egypt's duck industry, owing to their effects on feed utilization and body weight gain.
Aim: As a result, the goal of this study was to identify bacterial pathogens causing enteritis in ducks as well as testing their antimicrobials resistance capabilities.
Methods: Forty-two duck flocks from different localities at four Egyptian Governorates (El-Sharkia, El-Gharbia, El-Dakahlia, and El-Qaliobia) have been subjected to clinical and postmortem examination as well as bacterial isolation and identification.
Arg-73 of the RNA endonuclease MazF in Salmonella enterica subsp. arizonae contributes to guanine and uracil recognition in the cleavage sequence.

Electronic address:
The sequence-specific endoribonuclease MazF is widely conserved among prokaryotes. Approximately 20 different MazF cleavage sequences have been discovered, varying from three to seven nucleotides in length. Although MazFs from various prokaryotes were found, the cleavage sequences of most MazFs are unknown.
