  • Prevalence of Intestinal and Urinary Schistosomaisis in Five Localities in Gezira State, Sudan

Abstract
Background: Schistosomiasis is a neglected parasitic disease caused by S. mansoni and S. haematobium in Sudan. It is causing a chronic inflammatory process affecting the intestine and urinary bladder leading to a serious and fatal complications. Mehods: A total of 690 participants from five localities in Gezira State in Sudan were enrolled between March and August, 2016 in this study. Data on socio-demographic and risk factors were obtained using structured questionnaires. Clean containers with corresponding labels were used for samples collection. After processing stool and urine sample were microscopically examined for the ova of S. mansoni and S. haematobium respectively. Results: From the 690 participants enrolled in this study 396(57.4%) were male and 294(42.6%) were female, aged between 5 – 55 years, with the mean age ±SD (17.3 ± 3.7). This study revealed that the prevalence of S. mansoni was 6.7% (46/690) and S. haematobium was 7.5% (46/690), and overall prevalence of Schistosomiasis in the five localities was 14.2%. S. haematobium (11,9%, 1.7% ) and S. mansoni (9.3%, 3.1% ) were infected males more than females respectively. Conclusion: There is still a high prevalence of schistosomiasis in the study area. Safe water supply, provision of sanitation facilities, health education and sustainable rounds of mass chemotherapeutic intervention with Praziquantel are highly recommended to reduce the prevalence of this disease..

  • Pathogenicity of Xanthomonas campestris pv. allii causing bacterial leaf blight of onion in sudan and antibacterial efficacy of plant extracts

Bacterial leaf blight of onion, caused by Xanthomonas campestris pv. allii, is a new disease of green bulb onion in Sudan. A study was conducted to test pathogenicity of the causative agent of onion bacterial leaf blight and evaluate the efficacy of certain plant extracts against the pathogen. Antibacterial activity of aqueous ethanolic plant extracts of desert rose (Adenium obesum), eucalyptus (Eucalyptus microtheca), button wood (Conocarpus erectus), tamarind (Tamarindus indica) and mesquite (Prosopis julifora), at different concentrations, was assayed in vitro by well diffusion technique. The bacterium X. campestris pv. allii was isolated from leaf lesions and its pathogenicity was confirmed on onion leaves. There were significant differences between the extracts in their effect on bacterial growth and the best results were obtained at a high concentration (420 ppm) of plant extracts. Among the test plant extracts, mesquite extract revealed a high anti-bacterial activity with inhibition zone up to 38.6 mm. It was followed by eucalyptus extract with inhibition zone of 38.3mm, button wood and tamarind with inhibition zone of 38 mm each. Desert rose extract displayed lower inhibition zone of 20.2 mm as dcompare to the standard control of stryptomicin having inhibition zone of 36 mm. Thus plant extracts of eucalyptus, mesquite, button wood, and tamarind were promising and may help in the non-toxic, eco-friendly management of onion bacterial leaf blight disease.

  • Modification of PLA with Chain Extender

In this study, oligomer JoncrylTM ADR was used to extend the chains and improve the
mechanical properties. The chain extender multifunction epoxide was used with concentrations of
0.5 and 0.9 wt %. Pure and modified PLAs were characterized using DSC, MFI and FT-IR. The
DSC results showed that Tg shifted to the high temperature and Tm increased slightly after chain
extending. The MFI of the blends decreased with increasing the content of the CE which means the
increase of molecular weight. The coupling between epoxy groups of CE and end groups of PLA
was confirmed by FTIR tests. This coupling led to significant improvement in tensile strength and
modulus.
