isolation of brucella abortus from experimentally infected dromedary camels in sudan: a preliminary report.six camels were experimentally infected with two strains of brucella abortus, four with s19 and two with a field bovine strain. in all cases antibody titres were detected within 6 to 11 days. serum agglutination titres peaked between days 11 and 32 and complement fixation titres between days 11 and 52; both titres then declined steadily. no clinical signs were observed in the four camels inoculated with s19. slight non-specific symptoms were seen in the two camels infected with the field bovine ...19892517155
prevalence of antibodies to some viral pathogens, brucella abortus and toxoplasma gondii in serum from camels (camelus dromedarius) in sudan. 19872825450
enzyme-linked immunosorbent assay to differentiate the antibody responses of animals infected with brucella species from those of animals infected with yersinia enterocolitica o9.enzyme-linked immunosorbent assays using antigens extracted from brucella abortus with n-lauroylsarcosine differentiated natural brucella-infected animals from brucella-vaccinated or yersinia enterocolitica o9-infected animals. a field trial in mongolia showed cattle, sheep, goat, reindeer, camel, and human sera without infection could be distinguished from brucella-infected animals by conventional serological tests.200312853409
brucellosis in camels (camelus dromedarius) in darfur, western a field outbreak of brucellosis in 21 camels mixed with cattle, sheep and goats, five camels, three of which showed clinical signs, were serologically positive. in a subsequent abattoir survey of apparently healthy camels, six animals were seropositive, albeit with titres that tended to be lower than those found in the field outbreak. of the six seropositive slaughtered camels, five were shown to have lymph nodes (prescapular and supramammary) infected with brucellae (brucella melitensis biov ...200818346482
genotyping of brucella melitensis strains from dromedary camels (camelus dromedarius) from the united arab emirates with multiple-locus variable-number tandem repeat analysis.camel brucellosis is a widespread zoonotic disease in camel-rearing countries caused by brucella melitensis and brucella abortus. the aim of this study was the first genetic analysis of b. melitensis strains isolated from dromedary camels (camelus dromedarius) using multiple-locus variable-number tandem repeat analysis (mlva). mlva 16 and its mlva 8 and mlva11 subsets were used to determine the genotypes of 15 b. melitensis isolates from dromedary camels (11 strains) and other host species (4 st ...201627016751
serological survey of brucella abortus antibody prevalence in the one-humped camel (camelus dromedarius) from eastern sudan.a five year investigation of brucella antibody prevalence in camel sera was conducted in 1502 one-humped camels of both sexes and different ages. the average (mean +/- sd) incidence rate of positive results was 6.95 +/- 1.55%. among adult one-humped camels, the rate was 4.94 +/- 2.51% in males and 13.76 +/- 4.41% in females. juvenile one-humped camel calves showed a 0% incidence rate in males and a 1.82 +/- 3.64% in females. antibodies against brucella abortus were prevalent in one-humped camel ...19902128713
in vitro antibacterial effects of five volatile oil extracts against intramacrophage brucella abortus 544.brucellaabortus is a gram-negative facultative intracellular bacterium that can cause a highly contagious disease in sheep, goats, cattle and one-humped camels. it is responsible for one of the most important zoonosis in human. the aim of this study was to evaluate the role of mentha piperita, origanum majorana, citrus lemon, cinnamomum verum and myristica fragrans essential volatile oil extracts on human macrophages infected by b. abortus 544.201223115441
viral and bacterial infections associated with camel (camelus dromedarius) calf diarrhea in north province, saudi arabia.diarrhea and deaths in new-born camel calves were noticed by veterinary investigators and pastoralist in saudi arabia to be very high. hence, it is thought to be necessary to investigate this problem from the virological and bacteriological point of view. the role of pathogenic bacteria and viruses in six different towns of north province (al-assafia, arar, domat aljandal, hail, skaka and khoa) in saudi arabia was studied. survey was conducted in diarrheic camel calves aged 12 months or younger. ...201123961160
mastitis in camelus dromedarius and the somatic cell content of camels' hundred and sixty-three camels from 400 herds of local sudanese camel breeds were investigated for the prevalence of mastitis, identification of its bacterial causes and determination of the leucocyte contents of camel's milk. one hundred and forty-nine (19.5 per cent) of the 763 camels examined were diagnosed as mastitis cases based on clinical signs. one hundred and fifty-nine (47.3 per cent) of the 336 randomly selected milk samples were reactive in a rapid mastitis test and 16 of the 1 ...19968819195
first report on the isolation of brucella abortus biovar 3 from camel (camelus dromedarius) in the sudan.three isolates of brucella abortus biovar 3 were recovered out of 38 different samples obtained from free-ranging camels (camelus dromedarius) in eastern sudan. the biochemical characters of the isolates were identical to those of the other types of b. abortus except that they were oxidase negative.19947770659
brucellosis in camels.camels are highly susceptible to brucellosis caused by brucella melitensis and brucella abortus. difficulties can arise in diagnosis of camel brucellosis, especially as this disease provokes only few clinical signs in contrast to its clinical course in cattle. because none of the commonly used serological test can be perceived as a perfect test for brucella diagnosis in camel and most serological tests used for camels have been directly transposed from cattle without adequate validation, an inco ...201121632084
