“…This is in agreement with the results of a previous study in Sudan by Mustafa and Awad Elkarim (1971) in which they found an incidence of 3.5% in the Kassala and Butana areas using the tube agglutination test. These results compare with the incidence of 20% reported from Egypt (Zaki, 1948), 4.4% from Ethiopia (Domenech, 1977) and 1% from Nigeria (Okoh, 1979) Brucella infection was more common in camels sampled at Gedaref in the Eastern Region of Sudan than in the other regions.

“…1). However, in Egypt, Zaki (1948) reported that 26% of female camels and 14% of males had Brucella antibodies. In their study of Sudanese camels, Mustafa and Awad Elkarim (1971) did not specify the sex of the animals from which their samples were drawn.…”

“…Although B. suis biovar 1 presence in swine has been reported previously in Egypt, its current distribution is unknown [21], and it had not been reported in cattle before. Brucellosis infection in swine has been described in the country usually by means of serological techniques [3, 22] that cannot distinguish between infections by the different Brucella spp. In Egypt, swine (with an approximate population of 30,000 animals [3]) may live in small groups in contact with other animals and humans [23].…”

Brucellosis is endemic in most parts of Egypt, where it is caused mainly by Brucella melitensis biovar 3, and affects cattle and small ruminants in spite of ongoing efforts devoted to its control. Knowledge of the predominant Brucella species/strains circulating in a region is a prerequisite of a brucellosis control strategy. For this reason a study aiming at the evaluation of the phenotypic and genetic heterogeneity of a panel of 17 Brucella spp. isolates recovered from domestic ruminants (cattle, buffalo, sheep, and goat) from four governorates during a period of five years (2002–2007) was carried out using microbiological tests and molecular biology techniques (PCR, MLVA-15, and sequencing). Thirteen strains were identified as B. melitensis biovar 3 while all phenotypic and genetic techniques classified the remaining isolates as B. abortus (n = 2) and B. suis biovar 1 (n = 2). MLVA-15 yielded a high discriminatory power (h = 0.801), indicating a high genetic diversity among the B. melitensis strains circulating among domestic ruminants in Egypt. This is the first report of the isolation of B. suis from cattle in Egypt which, coupled with the finding of B. abortus, suggests a potential role of livestock as reservoirs of several zoonotic Brucella species in the region.

“…Brucellosis (Brucella abortus and Brucella melitensis) is endemic in almost all camel-producing countries, particularly in herds that commingle with other domestic ruminants [61,[65][66][67][68][69][70]. With the development of commercial camel dairies in several countries, this disease should be seriously considered because of its impact on human health.…”

Infectious causes of reproductive loss in camelids

et al. 2006

View full text Add to dashboard Cite

Reproductive losses in camelids are due to infertility, pregnancy loss, udder diseases and neonatal mortality caused by a variety of infectious diseases. Uterine infection and abortion represent the major complaint in camelid veterinary practice. The major infectious organisms in endometritis and metritis are E. coli and Streptococcus equi subspecies zooepidemicus. Abortion rates due to infectious diseases vary from 10% to more than 70% in some areas. Leptospirosis, toxoplasmosis and chlamydiosis have been diagnosed as the major causes of abortion in llamas and alpacas. In camels, brucellosis and trypanosomiasis represent the major causes of infectious abortion in the Middle East and Africa. Mastitis is rare in South American camelids. The prevalence of subclinical udder infection in camels can reach very high proportions in dairy camels. Udder infections are primarily due to Streptococcus agalactiae and Staphylococcus aureus. Neonatal mortality is primarily due to diarrhea following failure of passive transfer and exposure to E. coli, rotavirus, coronavirus, Coccidia and Salmonella. This paper reviews the etio-pathogenesis of these causes of reproductive losses, as well as the major risk factors and strategies to prevent their occurrence.
