Equine intestinal clostridiosis in a group of polo ponies in Dubai, U.A.E.

An acute outbreak of a C. perfringens Type C enterotoxemia in a polo club killed 8 polo ponies in less than 24 hours. Hay with a massive fungal contamination (Aspergillus and Fusarium sp.) is suspected to have triggered the enterotoxemia. Our cases show numerous similarities with the previously reported cases of EIC. However, acute toxic tubulonephrosis in the necropsied horses and longstanding elevation of AST and gamma GT-levels in survivors is unique in our cases.

[Blood parameters and enzyme values of healthy and sick racing camels (Camelus dromedarius)].

Camel races have a long tradition in Arabia. Since the oil boom of the 1960s a tremendous revival of the old Bedouin tradition of camel racing has occurred in the United Arab Emirates. These camel races are comparable to horse races in Europe and the U.S.A. Since 1985 the most valuable racing camels of Dubai are routinely tested in the Central Veterinary Research Laboratory (CVRL) for their stamina and endurance. Blood and serum enzyme values, which have been statistically ascertained through testing of 10000 healthy racing camels, are now generally accepted as reference values. Besides these check-ups of healthy racing camels, hematological tests, enzyme and substrate estimations are performed on sick racing camels. These tests support the diagnosis, therapy and prognosis of sick camels. In this connection three diseases are discussed: B. cereus intoxication, Clostridium perfringens enterotoxemia and Trypanosomiasis.

Avian paramyxovirus serotype 1 (Newcastle disease virus)--infections in falcons.

From eight falcons and one pigeon which died from NDV over a period of 15 months in Dubai, United Arab Emirates, PMV-1 viruses were isolated on quail embryo cell cultures. The identification of all 9 strains were achieved with the haemagglutination inhibition test against polyclonal chicken PMV-1 antiserum, against mouse monoclonal antibodies as well as with the immunoperoxidase test. Intracerebral pathogenicity index and intravenous pathogenicity index tests were also carried out. Although the virus isolates in this study fell into two distinct groups, the overall clinical symptoms displayed by the falcons tailed to demonstrate any trends or specificity unique to a group. The isolate obtained from a pigeon was similar to the isolates from one group of the falcons and showed no identity with the pigeon variant virus.

Severe heart muscle degeneration caused by Clostridium perfringens type A in camel calves (Camelus dromedarius).

Clostridium perfringens type A was isolated from different organs and intestines from three to five weeks old camel calves which have died from heart muscle necrosis. No other bacterial pathogens were isolated. Virus isolation on two different cell lines including a fetal camel skin were also negative. Mice which were injected with bacteria free filtrates prepared from intestinal contents of necropsied camel calves died after one to six hours demonstrating the presence of clostridial toxins. Our findings suggest that the cardiac muscle necrosis is caused by Clostridium perfringens type A toxins.

The barren camel with endometritis--isolation of Trichomonas fetus and different bacteria.

This study constitutes the first reported isolation of Trichomonas fetus from the uterus of breeding camels. Twenty-four of 68 camels, which were barren for 1-4 years were found to be positive for T. fetus. One preputial washing of a camel bull which had served the herd was found to be positive for T. fetus. The uterine flora of all camels were examined. Ten different bacterial and 2 fungal species were isolated. All samples were negative for Campylobacter sp., Taylorella equigenitalis and Streptococcus zooepidemicus.

Predisposing factors in enterotoxemias of camels (Camelus dromedarius) caused by Clostridium perfringens type A.

C. perfringens type A was isolated from different organs and intestines from breeding and racing camels which died from peracute and acute enterotoxemias in two separate outbreaks. Pathological changes in the digestive tract were mild in breeding camels, and severe in racing camels. A polyvalent clostridial antiserum of bovine origin given intravenously had a life-saving effect on breeding camels, but not on racing camels. In the two outbreaks, fifty percent of the breeding camels were suffering from an acute Trypanosoma evansi infection, and 25% of the racing camels had developed a salmonellosis. It is suggested that both infections played an important role as predisposing factors for the outbreak of C. perfringens enterotoxemias.

[Seroepidemiologic studies of the detection of antibodies to Brucella, Chlamydia, Leptospira, BVD/MD virus, IBR/IPV virus and enzootic bovine leukosis virus (EBL) in dromedary mares (Camelus dromedarius)].

Camels which are bred for the purpose of racing were tested serologically for 6 different animal diseases. The group were split into racing and breeding camels. The following results were achieved: Brucellosis, breeding camels 2%, racing camels 6.6%; Chlamydiosis 24%, 15%; Leptospirosis 2.5%, 5.6%; BVD/MD 9.2%, 3.6%. No antibodies were detected against IBR/IPV- and EBL-virus. The results are discussed under an epidemiological point of view.

Bovine brucellosis in the southern regions of the Somali Democratic Republic.

For the first time a survey of the prevalence of bovine brucellosis in three regions of the Democratic Republic of Somalia has been carried out. Blood sera were tested by the SAT and CFT and milk samples by the MRT. An average prevalence rate of 9.5 per cent (SAT) and 12.0 per cent (MRT) was found. There was considerable differences between regions and the reasons for this are discussed.
