  Trisodium Phosphate (TSP) as a food additive was studied for its effects on controlling the growth of halotolerant bacteria in the traditional Egyptian salted fish, faseikh. The experimental design included dividing the fish samples to 5 groups. First salted fish group was randomly purchased from the retail market as represent commercial product on retail sale. The other 4 groups were laboratory processed like simulated commercial condition using dry salting technique; in which two groups treated by addition of 0.5% TSP (w/w) with the salt mixtures and the other two groups were kept as control. Treated and control groups were stored at room (22°C) and chilling (4°C) temperatures for 60 day till ripening. When the obtained results were statistically compared to the markets group, 0.5% TSP significantly reduced (p<0.05) the counts of halotolerant bacteria by 2.5 and 3.7 logs in the treated fish groups stored at 22 and 4°C, respectively. Significant reduction (p<0.05) in the halotolerant bacterial counts was obtained in that control group stored at 4°C by 1.55 log10 CFU g-1. Combined reductions in the frequency of halotolerant strains by 2.58 were observed, when addition of 0.5% TSP with storage of salted fish groups at 4°C. Moreover, decreasing the storage temperature from 22 to 4°C resulted in complete reduction (100%) of the halotolerant pathogens in treated salted fish group. New regulations for salted fish products are required in order to establishing microbiological performance standards for halotolerant bacteria contamination and advice for the addition of 0.5% TSP as food additives to the products.

  Daily intraperitoneal administration of d-amphetamine sulphate at a dose of 8 mg kg 1 body weight to rats during 6-15 days of gestation has resulted in significant effect on sensory and motor reflexes of their pups. These pups have shown increased righting and rotating reflexes and cliff avoidance activity. Significant increase in brain noradernaline, 5-hydroxytryptamine and decrease in monoamine oxidase activity was observed in these pups and their mothers compared to their control counterparts.

  Gumboro disease associated with Colibacillosis in exotic layer and broiler chicks was reported in eastern Sudan. Mortality rate of the disease, 1.8% in layer and 1% in broiler chicks was recorded. In addition to, Escherichia coli (E. coli) was isolated from a layer chick. Factors which contributed to this were stated. Moreover some recommendations were outlined.

  This study was conducted to estimate the prevalence of the parasitic diseases in different animal species in Kassala area, eastern Sudan during 2004 up to 2006. A total of 1396 samples which were referred to Kassala Veterinary Research Lab were retrospectively studied. The samples were collected from different animal species; 1185 bovine, 139 ovine, 19 caprine, 46 equine and 7 camels. The study detected the following parasitic diseases: Anaplasmosis, theileriosis, trichostrogyliasis, microflariasis, coccidiosis, trypansomaiasis, moniezia sp. and mange.

  A case of aprosopia (facelessness) was described in a lamb at Elgash West abattoir in Kassala State, Eastern Sudan. The maxillary and mandibular bones of the deformed animal were completely absent (agnathia). There were 2 ears without external and internal orifices. Internally, the esophagus was opening in the larynx and 2 livers bilaterally were observed. The congenitally deformed lamb was hermaphrodite.
