Resistance patterns, virulence determinants, and biofilm genes of multidrug-resistant Pseudomonas aeruginosa isolated from fish and fish handlers.

Pseudomonas aeruginosa (P. aeruginosa) is an opportunistic bacterium that is widely distributed in aquatic environments and causes major economic losses in fish and public health hazards.This study aimed to identify the occurrence of P.

Antifungal and antibiofilm effects of probiotic , zinc nanoparticles, and zinc nanocomposites against from Nile tilapia (), water and humans.

Introduction: () can form biofilms; a critical virulence factor that provides effective protection from commercial antifungals and contributes to public health issues. The development of new antifungal therapies, particularly those targeting biofilms, is imperative. Thus, this study was conducted to investigate the antifungal and antibiofilm effects of (), zinc nanoparticles (ZnNPs) and nanocomposites (ZnNCs) on isolates from Nile tilapia, fish wash water and human fish sellers in Sharkia Governorate, Egypt.

Cross-sectional analysis of risk factors associated with in retail fish markets concerning methicillin-resistant and .

Introduction: and methicillin-resistant (MRSA) are potent bacterial pathogens posing major hazards to human health via consuming fish harboring these pathogens or by cross-contamination beyond the contaminated environment. The aim of this study was to determine risk variables associated with the presence of certain pathogenic bacteria from fish in retail markets in Egypt. The virulence genes of and were also studied.

Antibacterial and anti-biofilm activities of probiotic against isolated from milk, chicken and pregnant women.

() is a foodborne pathogen that poses significant risks to public health and food safety. The present study aimed to identify the presence of spp. in various samples, including pasteurized milk, chicken fillets, and stool samples from pregnant women in Sharkia Governorate, Egypt.

Interplay between cross sectional analysis of risk factors associated with infection in pregnant women and their domestic cats.

Toxoplasmosis is a global zoonotic disease caused by (). The primary aim of this study was to identify hygienic and cat management practices that could affect the occurrence of in cats and their owners in Sharqia Governorate, Egypt. infection was evaluated in 80 pregnant women and 29 domestic cats using Real-time PCR.

Molecular identification and antiprotozoal activity of silver nanoparticles on viability of Cryptosporidium parvum isolated from pigeons, pigeon fanciers and water.

Cryptosporidium is a protozoan that causes acute gastroenteritis, abdominal pain, and diarrhea in many vertebrate species, including humans, animals and birds. A number of studies have reported the occurrence of Cryptosporidium in domestic pigeons. Thus, this study aimed to identify Cryptosporidium spp.

Antimicrobial Resistance of and Isolated from Laying Hens, Table Eggs, and Humans with Respect to Antimicrobial Activity of Biosynthesized Silver Nanoparticles.

is one of the most common causes of foodborne illness worldwide. Contaminated poultry products, especially meat and eggs are the main sources of human salmonellosis. Thus, the aim of the present study was to determine prevalence, antimicrobial resistance profiles, virulence, and resistance genes of Enteritidis () and Typhimurium ( Typhimurium) isolated from laying hens, table eggs, and humans, in Sharkia Governorate, Egypt.

Molecular identification of avian influenza virus subtypes H5N1 and H9N2 in birds from farms and live bird markets and in respiratory patients.

Background: Avian influenza viruses (AIVs) have been endemic in Egypt since 2006, and the co-circulation of high-pathogenic avian influenza H5N1 and low-pathogenic avian influenza H9N2 subtypes in poultry has been reported; therefore, Egypt is considered a hotspot for the generation of new subtypes and genotypes. We aimed to characterize AIVs circulating on commercial farms and in live bird markets (LBMs) during the winters of 2015 and 2016 in the study area and to identify H5N1 and H9N2 viruses in respiratory patients.

Methods: In total, 159 samples were collected from ducks, pigeons and quails on farms ( = 59) and in LBMs ( = 100) and screened by real-time RT-PCR for H5N1 and H9N2 subtypes.

Molecular Characterization of Cronobacter sakazakii in Egypt, Survival and Thermoresistance at Different Temperatures: A Potential Public Health Risk.

Cronobacter sakazakii has been implicated in causing serious infections in neonates due to consumption of contaminated infant powdered milk. The zoonotic potential of the organism was not clear due to scarce evidence about the role of food animals in the transmission of infection. C.

Listeria monocytogenes in raw milk, milking equipment and dairy workers: Molecular characterization and antimicrobial resistance patterns.

Objectives: The aim of this study was to evaluate the genetic relatedness and patterns of antimicrobial resistance amongst L. monocytogenes isolated from raw milk, milking equipment, and hand swabs from workers in dairy farms.

Methods: A total of 300 samples of raw milk, milking equipment, and hand swabs were collected from four dairy farms to examine the presence of Listeria species.

Seroprevalence and risk factors associated with Toxoplasma gondii infection in domestic rabbits and humans.

A cross-sectional study was conducted from September 2014 to December 2015 to determine seroprevalence and potential risk factors associated with Toxoplasma gondii (T. gondii) infection in domestic rabbits and humans in Egypt. In total 290 blood samples were collected from humans (n=140) and slaughtered rabbits (n=150) and were analyzed using ELISA for T.
