zinc deficiency in sudanese desert sheep.reduced appetite, skin lesions and deaths occurred in sheep feeding on rhodes grass (chloris gayama) at a farm near khartoum north. the concentration of zinc in the grass and in the serum and liver of affected animals was low. these findings, the skin lesions and the favourable response to the injection of zinc (to be reported) suggest that the clinical condition was due to a deficiency of zinc in the diet of the sheep.19836643758

current situation of peste des petits ruminants (ppr) in the sudan.the current situation of ppr in sudan was investigated. a total of 61 tissue samples were collected from various ppr suspected outbreaks in sheep in sudan during 2008. collected tissue samples were tested for ppr antigen using icelisa, ppr antigen was detected in 26 out of 61 samples (42.6%). highest antigen detection rate was in specimens collected from western sudan. a total of 1198 serum samples were collected from sheep (n = 500), camels (n = 392), and goats (n = 306) from different areas in ...201019548103
a molecular survey of cystic echinococcosis in sudan.a survey of cystic echinococcosis in livestock was conducted from may 2001 to july 2003 in central, western and southern sudan. hydatid cysts were present in 59% (466/779) of camels, 6% (299/4893) of cattle, 11% (1180/10,422) of sheep and 2% (106/5565) of goats, with little variation among different geographical areas. 532 of these cysts were examined by pcr and could be overwhelmingly (98.7%) allocated to echinococcus canadensis g6/7 (all of 215 cysts from camels, 112 of 114 cysts from cattle, ...201020138433
