Detection of Antibodies against Bovine Brucellosis in ElHawata area, ElGadarif State, Sudan


The main objective of this research was to study bovine brucellosis in ElHawata area, ElGadarif State (2007). A total of 121 bovine sera were collected randomly from cattle of different age and breeds. Data regarding the history of the disease (frequent abortion) in the area were recorded. Samples were 1st subjected to serological investigation using Rose Bengal Plate Test (RBPT). Nineteen samples (15.7%) were found positive for antibodies against Brucellosis. The result was confirmed with (competitive ELISA) c-ELISA. The result of both tests was almost identical with one exception (one additional sample was found positive with c-ELISA). Only positive samples were tested with Serum Agglutination Test (SAT). The result confirmed that of c-ELISA and revealed antibody titer ranged between 17-1280. Regardless of age, the disease was detected in all groups, and it was more prevalent in cross breeds. It was concluded that bovine brucellosis is prevalent in ElHawata area, ElGadarif State, Sudan.

Brucellosis is a zoonotic disease with public health and economic implications. Losses in animal production due to brucellosis include diminution of milk and meat, abortion, infertility, longer calving intervals and higher culling rates.1 The disease poses great hazard to human health specially in countries where no proper program for disease control and the microbiological quality of milk is rarely checked. The first isolation of Brucella organism from animals was made by Bang2 who was the first to report contagious abortion in cattle and other animal species and he named his isolate Bacillus abortus, which was followed by other names, including Corynebacterium abortus, Bacterium abortus and Alcaligenes abortus.

 Lateral Rock Characteristic Evidence of Hydrocarbon Restoration from Post-Stack Impedance Inversion: A Case Study of ZED-field Offshore Niger Delta Lateral predictions of rock properties that are descriptive of a reservoir have been studied using a model-established seismic inversion approach that was used to convert input seismic data into an acoustic impedance structure to optimize hydrocarbon restoration in the field. This was actualized by integrating wireline logs and 3D post stack seismic data procured from ZED-Field offshore Niger Delta. The inversion system employed in this study comprises of forward modelling of reflection coefficients starting with a low-frequency impedance model induced from well logs and convolution of the reflection coefficients with the source wavelet extracted from the seismic input. P-impedance analysis at reservoir C5000 delineated from the control well gave a near perfect correlation of 0.998109 (≈ 99.8 %) between the original P-impedance log, in...

Prediction of Ionic Liquids Methane Hydrate Average Depression Temperature via COSMO-RS COSMO-RS is a tool used to pre-screen and pair ionic liquids for gas hydrate mitigation. However, the ionic liquids properties estimated from COSMO-RS lack direct connectivity to the determination of the safety margin (hydrate depression temperature) the inhibitor can alter on the hydrate phase boundary conditions. In this study, a parametric function that relates COSMO-RS estimated ionic liquid surface area and hydrogen bonding energies to the methane hydrate average depression temperature (∆T) have been presented. The statistical model in this study was developed using multiple linear regression techniques on about 90 data samples at 10 wt.% ionic liquids. The developed model in this work accurately predicts the methane hydrate average depression temperature with standard error of 3.14 and average deviation error of 0.92. Also, the ionic liquid surface area and hydrogen bonding energy contribute t...

 How to Treat Cancer Properly Cancer is one of the deadliest diseases in the world, chemotherapy is effective under some conditions, but has too heavy side effects, and it is not effective to a considerable proportion of cases while the side effects are often life-threatening, drugs (not unhealthy addictive drugs mentioned in reference four, the drug in reference four only mean those makes people addictive but does no good to health, destroying health quickly) are not always available to improve the condition. However, sport is a potential treatment that is effective to cancer before the cancer is disseminated, this gets little attention but is true both in theory and practice. The physical activities that have moderate intensity and duration should have devastating effects on cancer cells, they make the body hot and reduce the nutritional resources that cancer cells can get, also renew the proteins in the body and improve one’s mood, cancer cells are hard to live when one is activ...
