A novel bivalent Pasteurellosis-RHD vaccine candidate adjuvanted with Montanide ISA70 protects rabbits from lethal challenge.

In the present study, a bivalent vaccine against and rabbit hemorrhagic disease virus (RHDV) was formulated with Montanide™ ISA70 oil adjuvant (Seppic, Paris, France). Its efficacy was evaluated and compared to similar monovalent preparations and commercially available monovalent vaccines. White new Zeeland rabbit groups (n = 10) received 2 successive doses of the tested vaccines and were challenged 2 weeks after 2nd dose with and RHDV or either pathogens according to their vaccination schedule.

The occurrence of disinfectant and antibiotic-resistant genes in isolated from chickens in Egypt.

Aim: This work aimed to determine the occurrence of antibiotic and disinfectant resistance genes in isolated from chickens in Egypt.

Materials And Methods: Organs (liver, lung, heart, yolk sac, and bone marrow) of 1500 chicken samples were collected from diseased chickens suffered from colibacillosis with PM findings as CRD, diarrhea and omphalitis from different governorates of Egypt as: Giza, EL-Bahira, Fayoum, El-Dakahlia, El-Ismalia, and El-Sharkia during 2015-2016. These samples were labeled and transported immediately on ice to the Reference laboratory for quality control on poultry production (RLQP).

Isolation of antimicrobial producing from soil samples.

Emergence of multidrug resistant bacteria has made the search for novel bioactive compounds from natural and unexplored habitats a necessity. have important bioactive substances. The present study investigated antimicrobial activity of isolated from soil samples of Egypt.

Preparation of goat and rabbit anti-camel immunoglobulin G whole molecule labeled with horseradish peroxidase.

Aim: As the labeled anti-camel immunoglobulins (Igs) with enzymes for enzyme-linked immunosorbent assay (ELISA) are unavailable in the Egyptian market, the present investigation was directed for developing local labeled anti-camel IgG with horseradish peroxidase (HRP) to save hard curacy.

Materials And Methods: For purification of camel IgG whole molecule, camel sera was preliminary precipitated with 50% saturated ammonium sulfate and dialyzed against 15 mM phosphate-buffered saline pH 7.2 then concentrated.

Comparative studies for serodiagnosis of haemorrhagic septicaemia in cattle sera.

Haemorrhagic septicaemia caused by Pasteurella multocida is a major epizootic disease in cattle and buffaloes in developing countries with high morbidity and mortality rate. In the present study, a total of 88 P. multocida isolates were isolated from 256 nasopharyngeal swabs and lung tissues samples (34.

Molecular characterization of Escherichia coli O157:H7 recovered from meat and meat products relevant to human health in Riyadh, Saudi Arabia.

Raw meat can harbor pathogenic bacteria, potentially harmful to humans such as Escherichia coli O157:H7 causing diarrhea and hemolytic-uremic syndrome (HS). Therefore, the current study was carried out to evaluate the prevalence and the molecular detection characterization of E. coli serotype O157:H7 recovered from raw meat and meat products collected from Saudi Arabia.

Molecular and serotyping characterization of shiga toxogenic Escherichia coli associated with food collected from Saudi Arabia.

Shiga toxin-producing Escherichia coli (STEC) strains are considered as one of the major food-borne disease agents in humans worldwide. STEC strains, also called verotoxin-producing E. coli strains.
