Lumpy skin disease (LSD), a of cattle and buffaloes, has recently become widely prevalent in Egypt. The aim this study was to ascertain the potential role Rhipicephalus (Boophilus) annulatus ticks transmission disease. Samples collected from suspected lumpy virus (LSDV) infected cows that had previously been vaccinated with Romanian sheep pox (SPPV) various Egyptian governorates were obtained between May November over two consecutive years, namely 2018 2019. Ticks morphologically identified...
The quantity of healthy cells in a sample is known as cell viability. For all types culture, measuring viability crucial to ensuring high-quality lines through setup, preparation and storage. Although cryopreservation used both scientific clinical research, there are still certain restrictions. At low temperatures, such −196 °C metabolize almost nothing, which has unavoidable side effects, genetic drift toward biological variations cell-associated changes lipids. Also, can be harmed by...
Mastitis is considered a significant disease of lactating animals. There are new attitudes for recognizing genes responsible causing this to overcome and change the manipulation problem. This study aimed isolate identify Staphylococcusaureus strains from mastitic bovine animals detect some specific biofilm-forming (icaA, icaD, biofilm-associated protein [bap] clfA, fnbA, agrI, agrII, agrIII, agrIV, cna).A total 121 milk samples were analyzed using biochemical tests (catalase test,...
This study aimed to detect and characterize current genotypes of canine parvovirus (CPV) in Egypt during 2018.A total 50 fecal swabs were collected from clinically infected domestic dogs 2-5 months age, suspected suffer CPV infection, Cairo Giza Governorates. The samples subjected qualitative antigen detection using the rapid test, followed by isolation on Madin-Darby Canine Kidney (MDCK) cells, molecular characterization with partial amplification VP2 gene polymerase chain reaction (PCR),...
Newcastle disease (ND) is one of the most significant poultry viral diseases threatening industry worldwide.Despite mass vaccination against ND, genotype VII.1.1 epidemics in vaccinated and non-vaccinated flocks are still recorded, indicating an urgent need to generate a new vaccine candidate.In this study, live Orthoavulavirus javaense (AOAV-1) strain (CH-EGY-GIZA-VVTNRC-2021) (Genbank accession number MW603772) was attenuated by combining passaging with limiting 10-fold dilutions allantoic...
Ruminants are concerned as the prime reservoir for Shiga toxin-outputting Escherichia coli (STEC). Knowledge of STEC incidence in live animal is substantial to constituting informed deductions about food safety. A total 138 bacterial cultures (96 and 42 obtained from apparently healthy cattle sheep feces respectively. real time PCR was conducted using detect E. species. On other side, a conventional performed determine amplification toxin genes (stx1 stx2). isolates were confirmed by all...
Foot-and-mouth disease viral strains SAT2/EGY/2012, A Iran 05, and FMDV O PanAsia-2 could remain contagious after freeze-drying with minimum losses in infectivity, or without additives to virus suspensions. Over 12 months of storage at different temperatures, the infectivity titers freeze-dried viruses were evaluated on a regular basis. Additive solutions required prevent degradation throughout minimize loss during 4°C 20°C. Six added as stabilizers forming 6 mixtures: 1-Culture medium...
Aedes aegypti (L), (Diptera: Culicidae) is a major vector for the spread of several dangerous arboviral diseases, including Dengue Fever.Dengue fever (DF) one most common mosquito-borne viral zoonosis, affecting over 100 countries worldwide.Dengue and dengue haemorrhagic (DHF) are caused by four viruses serotypes (DENV-1 to DENV-4).The purpose this study was determine prevalence Ae. mosquitos their virus carriers in Egypt's Red Sea governorate between 2019 2020.From September December 2020,...
