a possible route for the introduction of rift valley fever virus into egypt during 1977.rift valley fever (rvf), which was enzootic in sudan in 1976 and epidemic in egypt in 1977-78, may have been introduced into egypt from sudan via sheep transported along lake nasser. a hypothesis is presented which describes sheep transport from holding areas in north-central sudan, where rvf was epizootic, to live animal markets in southern egypt. travel time from north-central sudan to the aswan area was less than 5 days, approximating the incubation period of rvf virus in sheep. reintroductio ...19863795324
serological evidence of crimean-congo haemorrhagic fever viral infection among camels imported into egypt.a serosurvey was conducted during 1986-87 to determine evidence of prior crimean-congo haemorrhagic fever (cchf) viral infection among camels imported into egypt from sudan and kenya. sera obtained from camesl arriving at the aswan quarantine station, southern egypt, were tested for cchf antibody by the agar gel diffusion (agd) and the indirect fluorescent antibody (ifa) techniques. cchf viral antibody was demonstrated in 14% (600/4301) of the camels, with both techniques yielding similar result ...19902112203
an epizootic of rift valley fever in egypt in epizootic of rift valley fever (rvf) occurred in egypt between april and august 1997. the signs among infected cattle and sheep were high fever, icterus, bloody diarrhoea and abortion. aborted sheep foetuses and sera from the affected herds were collected in the aswan and assiut provinces, upper egypt, for virological and serological examination. a cytopathic effect was detected in vero cell cultures 48 h after inoculation with the foetal liver and spleen suspensions. the same suspensions cau ...199910588018
recurrence of rift valley fever in egypt.rift valley fever (rvf) has been recorded in man and in domestic animals in egypt after a 12-year absence. human infections were first noted in the aswan governorate in late may, 1993. only cases of ocular disease, an infrequent and late manifestation, were reported. of 41 cases, 35 were tested serologically and 27 (77%) had rvf virus-specific igm antibodies. an estimated 600-1500 infections occurred in the region. abortions in cattle and buffalo were seen concurrently and antibodies to rvfv wer ...19937901480
animal hair as biological indicator for heavy metal pollution in urban and rural areas.animal hair is a good biomonitoring tool for heavy metals assessment and reflects the content of heavy metals in the forage and soil. heavy metals fe, mn, co and ni as well as toxic metals cd and pb were determined in goat, sheep and camel hair, forage and soil collected from four different environmental urban and rural regions. these regions are aswan city farms, allaqi desert pasture, kalabsha farms and halaiub desert pasture at far south of egypt. the results reveal that sheep hair contains t ...200516308777
