Epidemiology of rotavirus caused diarrhoea in infants in Oman E. M , Ebtihag; Y.H , Ali To investigate the epidemiology of rotavirus associated diarrhoea in children under 5 years of age in Sultanate of Oman. Methods: Data about the incidence of gastroenteritis, reported clinic visits, hospitalization during 2006-2008 was collected and statistically analyzed. Two regions were selected for the study (North and South Batinah). ELISA for detection of group A rotavirus antigen was applied on 200 fecal samples collected from diarrhoeic infants in the study area. Results: During 2006-2008 North Batinah had reported the highest prevalence rate (51.5%) of 2672 rotavirus tested feacal samples. Most of rotavirus positive cases were at 7-12 months of age. The incidence of diarrhea was slightly more in males (54- 55%). Out of 200 ELISA tested faecal samples in 2008, rotavirus antigen was detected in 125 (62.5%), of which 69.6% were in North Batinah while only 30.4 were in South Batinah. Highest prevalence of rotavirus was observed in 7-12 months of age (59%). Males comprised 53.6% of total positives. Conclusions: Rotavirus infection is found to be widely distributed in Oman. Highest prevalence of rotavirus was observed in 7-12 months of age (59%). Rotavirus associated diarrhea is more prevalent in North Batinah area in Oman. article

Investigation on the Decline of Balanites aegyptiaca (Heglig) tree Associated with the Cerambycid Beetle, Macrotoma palmata, in the Blue Nile area � Middle Region of Sudan Faris , Elsideeg Mohmedali Ahmed This study was done to assess the impact of the longhorn beetle, Macrotoma palmata,on Balanites aegyptiaca in the Sudan. The research was to investigate the phenomenon of the decline of the wood of the tree by the wood boring beetle. A total of 14 plots were randomly selected from Khour Abuseif forest, regenerated by B. aegyptiaca wood tree species. Each selected plot had a square shape, with an area of � hectare. In each selected plot, trees were counted and grouped into 2 different categories: sound trees and infested ones. For further recognition of the infested trees, dissection of the suspected branches was done to ensure the presence of one or all developmental stages of the pest. Mean frequency of infestation in the trees was determined in each selected plot by counting the infested ones in each chosen plot. Approximately, the overall mean frequency of infestation was 24% from the whole computed trees. In each selected plot, different growth parameters were measured in sound trees and compared with those of infested ones. High significant reductions, in the parameters of the infested trees, were recorded. The mean reductions in diameter at breast height (dbh), height (h), volume (v) and mean annual increment (m.a.i) of the infested trees in reference to sound ones was15.62%, 17.90%, 41.53% and 40.6% respectively. article

Effect of organic manures on yield and yield components of rain-fed sorghum in the Gedarif State. Ibrahim , Ibrahim Elsadig; Hassan , Ali Eltoum; Elasha , Elasha A.; Elagab , Salih Field experiments were executed for two seasons (2007/08 and 2008/09), at northern and southern Gedarif state with an objective to study the impact of organic manures addition on yield of rain-fed sorghum. The organic fertilizers used were; farm yard manure (FYM) and chicken manure (CM) at levels of 5, 10, 15 and 20 tons/ha for each manure (manually soil incorporated) plus a control. The experiment was sown to Arfa-Gadamak and arranged in a randomized complete block design with three replications. The land was twice ploughed and the crop was sown in rows of 80 cm apart at 20 cm between plants, thinned to 1-2 and 2-3 plant/hole after three weeks at the northern and southern Gedarif respectively, and weeded thrice. Sowing was on the 23rd at Kilo-6 and 26th of July at Doka in the first season, and on the 31Ist at Kilo-6 and the 13th of July at Doka in the second season. The data recorded in both seasons were, plant height, number of heads, grain yield, 1000 grain weight and straw yield. Statistical analysis was carried using MSTATC package and treatment means were compared using the least significant difference at 5 %. Also, the data were economically evaluated to test the efficiency of organic manures on the productivity of rain-fed sorghum and to find the most economical and optimum at level of these manures through assessing their profitability. The results showed that the addition of organic manure resulted in significant differences among all the measured attributes. Irrespective of the first level of farm yard manure (5 tons/ha), other treatments significantly increased sorghum grain yield also. Generally, the application of chicken manure was superior to farm yard manure and the highest grain yield was obtained at 20 ton/ha (1975 kg/ha) followed by 15 tons/ha (1552 kg/ha), 10 tons/ha (1390 kg/ha) and then by 5 tons/ha (994 kg/ha). The economic analysis showed that the chicken manure had both the highest net return and marginal rate of return (584 %) compared to farm yard manure especially at 5 tons/ha and was found as the most economic and optimum level for sorghum production under Gedarif State. From both statistical and economic analysis, the study recommended the application of chicken manure at 5 tons/ha (i.e. 2.1 tons/ feddan) for sorghum production in the Gedarif state. article

Studies on congenital infections in infants in Sudan: Seroprevalence of cytomegalovirus M , Nahla Kh; Y.H. , Ali; K. A. , Enan The occurrence of congenital infections in Khartoum State and the presence of human cytomegalovirus (HCMV) antibodies among pregnant women (IgG) and neonates (IgM) were studied. During 2002-2007 the total of births reported at Omdurman was 122503 with 2.4% deaths. In Khartoum province during 2004-2007 out of 6138 deliveries, 178 had died. The main reported congenital infections were jaundice, anomalies, hydrocephalus, and respiratory infections. In Omdurman the total infected neonates were 3189 with 873 deaths, retardation of growth had the higher percentage in infected cases and deaths. In Sudan during 2005-2007, respiratory infections had the higher number of reported clinical signs and Khartoum had the higher number of infections. Using ELISA 59 out of sixty (98.3%) pregnant women at last stage of pregnancy were positive for CMV IgG. Fifty out of 53 neonates plasma were positive for CMV IgM (94.3%). CMV was found to be highly prevalent in Khartoum State and it has a major role in causing congenital infections. article
