rift valley fever virus infections in egyptian cattle and their prevention.rift valley fever virus (rvfv) causes consistently severe outbreaks with high public health impacts and economic losses in livestock in many african countries and has also been introduced to saudi arabia and yemen. egypt with its four large outbreaks in the last 40 years represents the northernmost endemic area of rvfv. the purpose of this study was to provide an insight into the current anti-rvfv antibody status in immunized as well as non-immunized dairy cattle from the nile delta of egypt. du ...201728116860
using synoptic systems' typical wind trajectories for the analysis of potential atmospheric long-distance dispersal of lumpy skin disease virus.lumpy skin disease virus (lsdv) is an infectious, arthropod-borne virus that affects mostly cattle. solitary outbreaks have occurred in israel in 1989 and 2006. in both years, the outbreaks occurred parallel to a severe outbreak in egypt, and lsdv was hypothesized to be transmitted from egypt to israel via long-distance dispersal (ldd) of infected vectors by wind. the aim of this study was to identify possible events of such transport. at the first stage, we identified the relevant synoptic syst ...201726011073
q fever in cattle in some egyptian governorates: a preliminary study.q fever, caused by coxiella burnetii, is a zoonosis with great public health significance and can cause financial losses to animal owners. the knowledge of the epidemiology of q fever in egypt is limited. reports on this disease are scarce. in 2012 and 2013, we carried out this investigation to estimate the seroprevalence of antibodies to coxiella burnetii in dairy cows of nine farms located in the lower egyptian governorates of dakahlia, damietta and port said. 1,194 blood sera were randomly co ...201425481509
molecular typing of isolates obtained from aborted foetuses in brucella-free holstein dairy cattle herd after immunisation with brucella abortus rb51 vaccine in egypt.bovine brucellosis is endemic in egypt in spite of application of surveillance and control measures. an increase of abortions was reported in a holstein dairy cattle herd with 600 animals in damietta governorate in egypt after immunisation with brucella (b.) abortus rb51 vaccine. twenty one (10.6%) of 197 vaccinated cows aborted after 3 months. all aborted cows had been tested seronegative for brucellosis in the past 3 years. b. abortus was isolated from four foetuses. conventional biochemical a ...201627664334
detection of lumpy skin disease virus antigen and genomic dna in formalin-fixed paraffin-embedded tissues from an egyptian outbreak in 2006.an outbreak of lumpy skin disease (lsd) was reported in 2006 in egypt affecting 16 provinces. biopsies and post-mortem tissue samples were collected from calves that showed typical clinical signs of lsd and fixed in formalin. these samples were collected from a private dairy farm in the damietta province of egypt. formalin-fixed paraffin-embedded tissue samples were assessed using histology, and skin lesions were classified as either acute or subacute/chronic. both lumpy skin disease virus (lsdv ...201121699673
molecular and immunological detection of bovine herpesvirus-1 in clinical specimens.a nested polymerase chain reaction (nested-pcr), utilizing glycoprotein b (gb) gene of bovine herpesvirus-1 (bhv-1) as a target, virus isolation (vi), indirect immunofluorescence (ifa) and in situ immuno-peroxidase (ipr) staining in cell culture were conducted for detection of bhv-1 in suspected cattle, buffalo and sheep clinical specimens. the specimens were obtained in the form of nasal swabs, buffy coats and sera from different localities in egypt (ei-sharquia, dumyat and ei-fayoum). a total ...200517977217
