Abstract: A field experiment was conducted at Bel Air station, in Dakar using 15N isotope dilution technique and the non nodulating soybean (Glycine max) variety m129 as reference plant to test the compatibility of Dichlorofenthion-thiram (DCT) fungicide to the inoculation of common bean (Phaseolus vulgaris) Paulista variety with both Rhizobium etli ISRA 353 and R. tropici strain ISRA 554. Nodulation was not induced with R. etli ISRA 353 and nitrogen fixation did not occur. With R. tropici ISRA 554, a decrease in nodulation…

Abstract: Electrophoretic studies of multilocus-enzymes (MLEE) and whole-cell protein (SDS-PAGE) were carried out in order to evaluate the parity between different methods for the characterization of five Fusarium species recovered from cotton-growing areas in Egypt by numerical taxonomy methods. The obtained data revealed that SDS-PAGE and esterase isozymes are more efficient in grouping isolates in their respective species while peroxidase and malate dehydrogenase isozyme has much limited resolution in organizing all isola…

Abstract: Lactobacillus plantarum F1 and L. brevis OG1 isolated from Nigerian fermented food products, produced bacteriocins that had broad spectrum of inhibition against both pathogenic, food spoilage organisms and various lactic acid bacteria. The test organisms exhibited activities of 6400 and 3200 AU/ml respectively against Escherichia coli NCTC10418 and Enterococcus faecalis EF1, but did not inhibit Candida albicans ATCC10231 and Klebsiella sp. UCH15. Comparison of the antimicrobial spectra and characterization of the t…

Abstract: A 15-litre bench-top multipurpose bioreactor was designed and constructed. The vessel is a glass type with a stainless flat headplate incorporating 9 access ports allowing for a variety of interchangeable probes and actuators. The stirring speed ranges between 0 and 250 rpm, the aeration rate (0-2 l/m), the pH control loop uses HI 1131 probe, two 100 ml bottles of HCl and NaOH solutions and operates a close feedback system. The temperature control module is a close loop using a PT 100 RTD thermocouple and an auxili…

Abstract: In a survey of 200 pregnant women (mean age 24 years) attending a traditional birth home (TBH) in Abeokuta, Nigeria, 19 (9.5%) were found to be rhesus negative, 8 (42.1%) of which were primigravidae while 11 (57.9%) were multigravidae. 87.5% of the Rhesus negative primigravidae delivered at the TBH without being given the post partum injection of anti-D-gama globulin within 72 h of delivery, thereby having their systems likely sensitized (if baby is rhesus positive) against subsequent pregnancies involving Rhesus p…

Abstract: Three patients, 30, 2 and one and a half years, were diagnosed as having falciparum malaria and were placed on chloroquine therapy which failed. They were then placed on quinine therapy that then cleared the parasitaemia. This case report seeks to draw the attention of the presence of possible chloroquine-resistant falciparum malaria in Sokoto, North Western Nigeria.[...]

Abstract: The haematological changes observed with commercially available haematinics (Fagon 9® and Chemiron®) were compared with those of a local haematinic referred to as African Herbal Formula (AHF). Results showed that AHF produced effects in haemoglobin (Hb) and packed cell volume (PCV) levels which are reasonably comparable with the reference commercial and chemically defined haematinics.[...]
