Studies on the Efficacy and Safety of Certain Fasciolicidal Drugs in Sudanese Desert Sheep

The efficacy and safety of three fasciolicidal drugs; nitroxynil, niclofolan and triclabendazole against mature (11-week-old) and immature (5-week-old) Fasciola spp. infection were investigated in male desert sheep. Nitroxynil (Trodax®) at a dose rate of 10 mg/kg, Subcutaneously caused a 99% reduction of mature fluke burden while the drug at the same dose was 70% effective against immature...

Pathogenicity of Some Bluetongue Viruses Isolated In the Sudan in Sudanese Cattle and Sheep

The pathogenicity of bluetongue viruses isolated from sheep, cattle or Culicoides sp. midges were studied in sheep and cattle of local breeds. Twelve sheep and 12 calves of 6 to 12 months old were initially screened for the presence or absence of antibodies against bluetongue virus. Susceptible animals were divided into four groups A, B, C and D. Each group contained 3 sheep designated as A1, B...

Identification and Pathogenicity of Mycoplasmas Isolated From Natural Cases of Contagious Caprine Pleuropneumonia In the Sudan

Mycoplasmas from pneumonic goats in six Geographic areas in the Sudan were studied. The isolation was carried out from 249 samples consisting of 180 pneumonic lungs and 69 pleural fluids. 18 Mycoplasma isolates were recovered. Using biological, biochemical and serological tests, the 18 isolates were categorized into 4 different groups. The first group included 3 strains of M. mycoides subsp....

Studies on the Susceptibility to Fasciola gigantica Infection in Goats with Special Reference to Levamisole Treatment

The susceptibility of Nubian goats to the experimental infection with Fasciola gigantica was investigated in connection with primary infection, reinfection, cross infection with Schistosoma bovis and vaccination with F. gigantica-irradiated metaceraariae. Immunomodulatory effect of Levamisole (L-tetramisle) was also evaluated on the primarily infected animals and with vaccination with...

The Effect of Experimental Fasciola gigantica Infection on the Performance of Male Nubian Goats

The effect of experimental Fasciola gigantica infection on the clinical health and performance was investigated in male Nubian goats. Eight (6-7 months old) bucks were infected with 200 F. gigantica metacercariae and kept for 14 weeks for clinical observation and evaluation of feed lot performance, feed digestibility and semen quality. Four uninfected bucks of the same age and breed were also...

Studies on Naturally Occurring and Experimental Ovine Fascioliasis in the Sudan

Fascioliasis is one of the most important parasitic diseases of domestic ruminants in the Sudan. The disease causes tremendous economic losses through partial condemnation of infected livers and total condemnation of whole carcasses on account of general emaciation, characteristic of the chronic infection. The disease is prevalent in many areas of the Sudan especially the White Nile area which...

Studies on Camel Haemonchosis Caused by Haemonchus Longistipes (Railliet and Henry, 1909) in the Sudan

The clinico-pathological features and parasitological aspects of naturally-occurring and experimentally-induced Haemonchus longistipes infection of camels together with that induced in a co-habiting host, the goat, were studied. The infected animals were examined ante-mortem and post-mortem and jugular blood was obtained from each animal for haematological and biochemical determination. It was...

Study of the Pathogenicty of Experimental Borrelia Anserina Infection in Chickens

The pathogenicity of experimental Borrelia anserina infection was studied and compared in White Leghorn and indigenous Baladi fowls. Both breeds were kept under tick-proof pens. Birds of different age groups were inoculated intravenously with infected blood and only one virulent strain of B. anserina was used throughout. White Leghorn fowls were found more susceptible to infection than Baladi...

Epidemiological Studies on Bovine Fascioliasis in the White Nile Province

The survey showed that most animal owners in Kosti district lead a nomadic way of life moving with their herds within and outside the district in search of grass; usually well known migration routes are annually followed by the tribes. Fascioliasis proved to be endemic in the White Nile Province and the prevalence rate of the disease in cattle varies in different localities; this may have...

The Role of Nutrition on the Pathogenesis of Schistosoma bovis in Sheep and the Effect of Infection on Carcass Characteristics

Eighteen Desert sheep were divided into four groups (A, B, C and D). Each animal in groups C and D was daily given four kg of ration consisting of three parts green lucerne and one part sorghum grains while group A and B were provided half of that amount. Water was provided ad libitum. Animals in groups A and C were infected percutaneously with 4000 Schistosoma bovis cercariae. Animals in...
