Determination Of Mycobacterium Tuberculosis Odour Compounds Detected By Cricetomys Gambianus Rats For Diagnosis Of Pulmonary Tuberculosis In Low-Income Settings

ABSTRACT Novel methods for rapid diagnosis of tuberculosis (TB) are urgently needed to complement the widely used smear microscopy in low income settings. Trained TB detection rats offer a promising tool for rapid diagnosis of TB in resource limited settings. The Mycobacterium tuberculosis (Mtb) specific volatile compounds detected by trained Cricetomys gambianus rats in sputum of TB patients are unknown. It is also not known whether rats detect odour signals from other mycobacteria and...

Single Nucleotide Polymorphisms In Insulin-Like Growth Factor (Igf) Genes And Their Associations With Growth In Local Guinea Fowls (Numida Meleagris) Of Ghana

ABSTRACT Due to the pivotal role of Insulin-like Growth Factor 1 (IGF1) and Insulin-like Growth Factor 2 (IGF2) in growth regulation of poultry, the IGF1 gene (gIGF1) and IGF2 gene (gIGF2) in guinea fowl were examined as candidate genes for early growth in helmeted guinea fowls (Numida meleagris) from three populations of Northern Ghana (TPNG). Keets hatched from eggs collected from 32 sample locations comprising 11 subpopulations across three main populations located in Upper East Regi...

Three Species Of The Genus Rhabdosargus Fowler, With Special Reference To The Ffwhite Stumpnose", R.Globiceps (Cuvier)

The Zoology Department of the u.c.T. has been making an ecological survey of South Afr1,can estuaries. The plant and animal lif'e of many estuaries has been studied in relation to physico-chemical conditions, and bottom fauna has been dealt with in great detail. Not much is known about the fish populations that occupy these estuaries. It was theref'·ore decided that some information about typical estuarine fish might be of use. For the first four months nettings were made at ...

Life history of Chrysichthys catfish in Volta Lake, Ghana

ABSTRACTThis study, undertaken during 1974 to 1977 in Volta Lake, investigatedthe identification, abundance and distribution, reproductive biologyand weight-length relationships of four Chrysichthys species (C . a u ratus,C. walkeri, C. velifer and C. furcatus). The species were separated onbasis of position of the dorsal fin, color of the barbels and the bodyand shape of the caudal fin and its lobes. Gill rakers also proved ofsome value.The Volta Lake, on the Volta River in Ghana, is the lar...

Effects Of Larval Diet On The Fitness And Insecticide Resistance Profile Of Anopheles Gambiae S.L. (Diptera: Culicidae) From Opeibea Area In The Greater Accra Region, Ghana.

Malaria is a life-threatening disease and is hyper-endemic in Ghana. The Anopheles gambiae complex is established to contain the main vectors that transmit malaria parasite, Plasmodium falciparum in Sub-Saharan Africa and it has been implicated as the main vector of malaria in Ghana. Vector control remains the most effective measure to prevent malaria transmission. This can largely be achieved by the use of insecticides. However, the effectiveness of insecticide-based...

Evaluation Of The Efficacy Of Wormatak® (Teflubenzuron And Cypermethrin) Against Anopheles Gambiae Sensu Lato And Its Impact On Non Target Organisms

This study investigated the efficacy of WormAtak® against Anopheles gambiae s.l. larvae, pupae and adults (Diptera: Culicidae) collected from Opeibea and Madina in Ghana and its effect on three non-target organisms under laboratory conditions. Anopheles gambiae s.l. and the non-target organisms were all exposed to five concentrations of WormAtak® (1.86 µM, 3.71 µM, 5.57 µM, 7.42 µM and 9.28 µM). Mortality was recorded for a period of 72 hours for Anopheles gambiae&n...
