The pathogenic potential of vancomycin and methicillin-resistant coagulase-negative Staphylococci (VMRCoNS) on Egyptian poultry farms has received little attention. Therefore, this study aims to the prevalence CoNS in imported flocks commercial farms, evaluate presence virulence antibiotic resistance genes (sea, seb, sec, sed, see, mecA), assess their pathogenicity broiler chicks. Seven species were identified among 25 isolates, such as 8 S. gallinarum, 5 saprophyticus, chromogens, 3...
Multidrug resistance poses a global threat to the poultry industry and public health, so direction towards eliminating use of antibiotics finding alternatives is vital step solve this problem. Thyme microemulsion (10% oil/water) had nanodrop size 28.65 ± 0.89 nm, with polydispersity index (PDI) 0.28 greater homogeneity. It showed IC50 > 100 ug/ml on cytotoxicity assay 14 active components by GC-Mass. The study was carried out using 210 Cobb chicks divided into fourteen groups. infected...
The cytokine storm induced by duck hepatitis A virus type 1 (DHAV-1) infection significantly contributes to severe, rapid deaths and economic losses in the industry Egypt. This study aimed investigate potential inhibitory effect of a nano-emulsion containing turmeric black pepper oil on immune response pathogenesis DHAV-1 ducklings. total 105 ducklings from non-vaccinated breeders were divided into 5 experimental groups, each comprising 21 birds. negative control group (G1) remained...
LPAI H9N2 infection among the poultry population in Egypt constitutes an additional risk factor industry. This study aimed to determine prevalence of avian influenza virus (AIV) commercial and backyard chickens Egypt. A 2-year survey AIV farms backyards was carried out 2015 2016.Direct detection performed by detecting tracheal cloacal swabs using real-time polymerase chain reaction assays. total 20,421 samples were collected from 26 Egyptian governorates.In 2015, cases positive for numbered...
Mycoplasma gallisepticum (MG) infections cause significant economic losses to the poultry industry worldwide. Vaccination with live and inactivated vaccines administration of antibiotics are commonly used as control measures. Herein, we describe a 27-wk-old broiler-breeder vaccinated TS-11 MG vaccine at 10 wk age. The flock subsequently exhibited mild respiratory signs slight decrease in egg production 27 Serological examination serum samples using plate agglutination test revealed 32%...
Since it was first discovered, the low pathogenic avian influenza (LPAI) H9N2 subtype has established linages infecting poultry population globally and become one of most prevalent subtypes in domestic poultry. Several different variants genotypes LPAI viruses have been reported Egypt, but little is known about their pathogenicity how they evolved. In this study, four Egyptian were genetically antigenically characterized compared to representative from G1 lineage. Furthermore, three distinct...
This study was conducted to investigate the effect of dried cafeteria leftover food (DCLF) incorporation in growing APRI rabbit diets on nutrient digestibility, live body weight, weight gain, carcass traits, meat quality, blood parameters, and economic efficiency. Thirty-six rabbits (6 weeks age), after weaning, were randomly divided into three groups (12 rabbits/group, 613 ± 5 g). During experiment, aged 6-14 participated experiment. An approximate isocaloric isonitrogenous composition...
One of the most prominent viral diseases affecting poultry industry is hydropericardium syndrome caused by fowl adenoviruses. Hydropericardium has recently led to significant economic losses in Egyptian sector. Many outbreaks have been documented across country last few years. This research examined epidemiology and molecular characterization adenoviruses broiler chickens Egypt. Samples were taken from 26 commercial chicken farms Beheira Menofia governorates, Egypt, January 2021 March 2022....
paper presents a new technique for calibrating heliostat errors which affect the efficiency and production of thermal energy from reflected beam mirror to target.This is based on analyzing image identifying different deterministic error types in single facet small heliostat, such as pedestal tilt deformation due wind loading.The depends constructed beam.For each image, seven features are extracted stored.These moment invariant technique, insensitive translation, rotation, scale changes.The...
P arvoviruses cause significant economic losses for domestic waterfowl producers.From June 2020 to January 2022, eight mule and four pekin duck farms were investigated parvovirus in Al -Beheira governorate, Egypt.The affected ducks exhibited severe growth retardation with atrophied deformed beak, a protruding tongue, profuse white diarrhea, locomotor dysfunction lost their feathers, especially on the back, neck, wing.The mortality rate was 10 %-18% morbidity 60%-80% flocks.Histopathological...
Abstract In late 2016, Egypt was subjected to multiple introductions of reassorted highly pathogenic avian influenza viruses (HPAI) subtype H5N8. a previous study, we reported three distinct genotypes during the first wave infection represented by CAO285, SS19, and F446 that were isolated from wild birds, backyard, commercial farm, respectively. F466 has subsequently become predominant genotype currently circulating in been implicated emerging H5N2 virus. present investigated difference...
Highly pathogenic avian influenza virus (HPAIV) H5N1 is an endemic disease in Egypt and severe outbreaks have been reported even vaccinated flocks. Several H5 vaccines failed to protect birds against Egyptian virus. In this study, the antiviral effect of green tea extract (GTE) combination with inactivated vaccine was evaluated. GTE found be safe at high concentration on Vero cells decrease CPE infected cells. vivo, specific pathogen free chickens were allocated into four groups, 15 each....
