Role Of Some Passeriformes Birds In Experimental Transmission Of Newcastle Disease Under Sudan Conditions

Five species of wild birds were inoculated with velogenic viscerotropic Newcastle disease virus (VVNDV) to determine their susceptibility to it. Host response was monitored by virus reisolation, clinical signs, postmortem lesions and antibody response. All the five species of wild birds were shown to be susceptible to infection with the virus with minor variations within species. Durra birds...

The Aetiology of Abscess Disease of Sheep in the Sudan

A survey was carried out in Khartoum Commissionaire and North Kordofau Province to determine incidence and aetiological agents of abscesses among sheep. Examination of 2962 sheep at Omduman Central Abattoir, ELmasara Farm at Hulfyat Elmulok, EL Baggaire and EL Kadaro areas, the University Veterinary Hospital at Shambat and Hamrat ELwiz in Northern Kordofan revealed that 372 (12.6%) animals had...

Mycoplasmas Isolated From the Respiratory and Genital Tracts of Camels in the Sudan

Mycoplasma isolates (2.2%) were recovered from 363 samples, collected from various camel sources. Six isolates were obtained from 148 (4.05%) nasal swabs. Two isolates were obtained from 145 (1.37%) pneumonic lungs. No isolate was recovered from 47 tracheal swabs and from 23 vaginal swabs. Two isolates, one from a pneumonic lung and the other from a nasal swab were lost during subculture and...

Bacteriology of Processed Meat in Sudan

A total of 204 specimens of meat were purchased from butcheries groceries, suppermarkets and public markets distributed throughout the National Capital. The meat specimens that included sausages, ground meat hamburger, kuftta, sun dried meat (sharmoot) and pastorma were either stored at 4C (refrigerated) or kept at -12C (frozen). The period of storage before sale was unknown. The specimens...

Prevalence and Properties of Clostridium perfringens in Broilers in the Sudan

In this study, 79 samples collected from the local breeds of birds and foreign breeds of broilers for the presence of C. perfringens; 131 isolates were obtained. These organisms were also recovered from poultry feeds, oyster's-shell, soil and litter with low incidence compared with poultry. Of the 120 samples, only 89 isolates were recovered. Bacteriological, bio- chemical and serological tests...

Study on the Recovery and Properties of Cold Injured Bacteria Isolated From Processed Meat

Studies were carried on the effect of low temperatures on the recovery of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Clostridium perfringens isolated from processed meat. These four organisms were found susceptible to low temperatures, and this susceptibility appeared in forms of death or injury. Ps. aeruginosa and C. perfringens were the highly susceptible ones to the...

Comparative studies on the properties of C. chauvoei (Sudanese Kad1 strain and CH3 strain) and the prevalence of C. chauvoei and C. septicum on livers and spleens of slaughtered cattle

Comparative studies were carried on a local Sudanese strain (Kad1) of C. chauvoei and a highly immunogenic strain (CH3). The studies demonstrated the ability of both strains to grow well both on an alkaline pH medium and at a temperature ranging from 30-40C. The response of both strains to change in pH and temperature was found to be the same. Studies on growth requirements revealed that C....

Studies on the properties of Clostridium chauvoei and Clostridium septicum and their role in Blackleg disease

A newly isolated local Sudanese strain Clostridium chauvoei (Kad1) was studied (compared with C. chauvoei (CH3) and C. septicum obtained from the Commonwealth Serum Laboratories, Australia. Properties of C. chauvoei and C. septicum were studied to determine the requirements of these organisms and their role in the aetiology of blackleg disease. The cell wall of C. chauvoei was found to be more...

Studies on the Properties of Clostridia of AS-gangrene Group and Enterotoxaemia Group with Special Reference to Their Fatty Acids Products

Biochemical properties of Clostridia of the Enterotoxaemia group and gas gangrene group were studied. Variations in the behaviour of different strains were reported. Short chain fatty acids extracted from the culture media of the strains representing these two groups were analysed using the gas liquid chromatography. The strains of the Enterotoxaemia group (not including Clostridium sordellii...

Mycoplasmas Associated with Caprine Pneumonia in the Sudan

The present study was concerned with isolation, characterization and pathogenicity of mycoplasmas from pneumonic goats. Of all samples examined culturally for presence of mycoplasmas, 15 isolates were recorded. These were identified as mycoplasmas according to generally accepted biological criteria. According to biochemical and serological tests, the isolates fell into two groups. None of the...
