Towards a sterile insect technique field release of <it>Anopheles arabiensis </it>mosquitoes in Sudan: Irradiation, transportation, and field cage experimentation
No full textAbstract Background The work described in this article forms part of a study to suppress a population of the malaria vector Anopheles arabiensis in Northern State, Sudan, with the Sterile Insect Technique. No data have previously been collected on the irradiation and transportation of anopheline mosquitoes in Africa, and the first series of attempts to do this in Sudan are reported here. In addition, experiments in a large field cage under near-natural conditions are described. Methods Mosquitoes were irradiated in Khartoum and transported as adults by air to the field site earmarked for future releases (400 km from the laboratory). The field cage was prepared for experiments by creating resting sites with favourable conditions. The mating and survival of (irradiated) laboratory males and field-collected males was studied in the field cage, and two small-scale competition experiments were performed. Results Minor problems were experienced with the irradiation of insects, mostly associated with the absence of a rearing facility in close proximity to the irradiation source. The small-scale transportation of adult mosquitoes to the release site resulted in minimal mortality ( Conclusion It is concluded that although conditions are challenging, there are no major obstacles associated with the small-scale irradiation and transportation of insects in the current setting. The field cage is suitable for experiments and studies to test the competitiveness of irradiated males can be pursued. The scaling up of procedures to accommodate much larger numbers of insects needed for a release is the next challenge and recommendations to further implementation of this genetic control strategy are presented.</p
Identification and Sensitivity of Aerobic Bacteria Isolated from Urine of Chronic Renal Failure Patients
No full textSudan is a large country with about 39 million people and an
annual incidence of chronic renal failure (CRF) of about 70-140
pmp/year. This study was conducted toevaluate the presence of urinary
tract infection (UTI) and identify the bacteria commonly associated with
this infection in Sudanese patients with CRF. Fifty patients were
randomly selected from patients with CRF being treated by
heamodialysis (HD) in the periodfrom March 2006 to May 2007.
The study revealed that the male: female ratio was 1.9:1 and all of
them were out patients. The prevalence of significant RBCs on urine was
42% and that of significant pyuria was 38%. The presence of bacterial
infection on urine culture was 74%.
The commonest organism isolated was Escherichia coli, accounting for
42%.The other isolates were Proteus mirabilis12% , Pseudomonas
aeruginosa6% , Staphylococcus saprophyticus 14% , Staphylococcus
caseolyticus14% , Staphylococcus intermedius12% , and
Staphylococcus aureus4%.
Of the isolated organisms, 98% were sensitive to one or more of
the tested antibiotics, and the best antibiotics of high effectiveness were
Gentamycin (96.7%) and Nalidixic acid (70%

Rational deployment of antimalarial drugs in Africa: should first-line combination drugs be reserved for paediatric malaria cases?
No full textArtemisinin-based combination therapy is exerting novel selective pressure upon populations of Plasmodium falciparum across Africa. Levels of resistance to non-artemisinin partner drugs differ among parasite populations, and so the artemisinins are not uniformly protected from developing resistance, already present in South East Asia. Here, we consider strategies for prolonging the period of high level efficacy of combination therapy for two particular endemicities common in Africa. Under high intensity transmission, two alternating first-line combinations, ideally with antagonistic selective effects on the parasite genome, are advocated for paediatric malaria cases. This leaves second-line and other therapies for adult cases, and for intermittent preventive therapy. The drug portfolio would be selected to protect the 'premier' combination regimen from selection for resistance, while maximising impact on severe disease and mortality in children. In endemic areas subject to low, seasonal transmission of Plasmodium falciparum, such a strategy may deliver little benefit, as children represent a minority of cases. Nevertheless, the deployment of other drug-based interventions in low transmission and highly seasonal areas, such as mass drug administration aimed to interrupt malaria transmission, or intermittent preventive therapy, does provide an opportunity to diversify drug pressure. We thus propose an integrated approach to drug deployment, which minimises direct selective pressure on parasite populations from any one drug component. This approach is suitable for qualitatively and quantitatively different burdens of malaria, and should be supported by a programme of routine surveillance for emerging resistanc
