Article Synopsis
  • The study analyzed 49 strains of a common hospital pathogen from humans, dogs, and cats using NGS technology, revealing that standard identification methods (MALDI-TOF) were inadequate for some newly discovered isolates.* -
  • Notably, different sequence types were identified among the strains, with human isolates showing higher resistance to multiple antibiotics, including extensive drug-resistant types, whereas animal isolates were generally less resistant.* -
  • The research indicated inconsistencies between observed resistance patterns and genetic data, suggesting a need for more extensive studies to understand antimicrobial resistance across various sources, highlighting the importance of a One Health approach in monitoring infections in Egypt.*

Article Synopsis
  • Brucellosis is a sickness caused by bacteria that affects both people and animals, causing health problems and money loss in farming in Türkiye and other countries.
  • Researchers studied the genes of 106 samples from animals and humans in Türkiye to understand how they differ from each other and from samples in other countries.
  • The study found different types of the bacteria in Türkiye, showing they are also related to bacteria from neighboring countries and some European countries, which means travel might help spread the disease, so better controls are needed to keep it from spreading.

Edible films and essential oil (EO) systems have the potency to enhance the microbial quality and shelf life of food. This investigation aimed to evaluate the efficacy of chitosan films including essential oils against spoilage bacteria and foodborne pathogens associated with meat. Antimicrobial activity (in vitro and in vivo) of chitosan films (CH) incorporated with oregano oil (OO) and thyme oil (TO) at 0.

Brucellosis is among the most prevalent zoonotic infections in Middle Eastern and North African (MENA) countries, critically impacting human and animal health. A comprehensive review of studies on antibiotic susceptibility and therapeutic regimes for brucellosis in ruminants and humans in the MENA region was conducted to evaluate the current therapeutic management in this region. Different scientific databases were searched for peer-reviewed original English articles published from January 1989 to February 2021.

Article Synopsis
  • * Out of 50 milk samples collected, a total of 17 enterococci and 8 coliform isolates were successfully grown, revealing a high rate of vancomycin resistance and confirming that all isolates were ESBL-producing using the VITEK 2 system.
  • * Genetic testing identified multiple resistance-associated genes, with the presence of various virulence genes and specific serotypes, indicating significant antimicrobial resistance and potential health risks related to dairy products.

Aim: This study aimed to characterize the genetic diversity, evolutionary level, and prevalence of genotypes of common isolates of ( Enteritidis and Typhimurium). Using one of the most advanced molecular recognition techniques, multilocus variable number of tandem repeat analysis (MLVA), we characterized the genotype and prevalence of . Enteritidis and .

Background And Aim: is one of the emerging gram-negative bacteria, which associated with foodborne illness. Researches affirmed that distinguish between and are difficult, as they are phylogenetic related. The evolution of multidrug resistance of strains gained more concern for recognition of the pathogen which supports in controlling the disease and minify its threat.

This study aimed to investigate how efflux pump activity contributes to high fluoroquinolone (FQ) resistance in Campylobacter jejuni and Campylobacter coli isolates and to evaluate the modulatory effects of α-tocopherol and aspirin on FQ phenotypic resistance profiles. Minimum inhibitory concentration (MIC) values were obtained for different FQ agents following exposure to different efflux pump inhibitors (EPIs), including PaβN (50 μg/mL), which targets the cmeABC efflux system, and chlorpromazine (45 μg/mL) and verapamil (120 μg/mL), which target the MFS efflux system. The modulatory effects of aspirin (100 and 200 μg/mL) and α-tocopherol (4 and 10 μg/mL) on FQ resistance profiles were examined.

The public health importance of the genus Campylobacter is attributed to several species causing diarrhea in consumers. Poultry and their meat are considered the most important sources of human campylobacteriosis. In this study, 287 samples from chicken (131 cloacal swabs, 39 chicken skin, 78 chicken meat, and 39 cecal parts) obtained from retail outlets as well as 246 stool swabs from gastroenteritis patients were examined.
