SEXUALLY TRANSMITTED DISEASES (STDs) AND ACQUIRED IMMUNODEFICIENCY SYNDROME (AIDS) IN NIGERIA
B.A Onile
African Journal of Clinical and Experimental Microbiology , 2002,
Abstract: The sexually Transmitted Diseases constitute major public health problems in Nigeria. There is early sexual maturity and considerable sexual activity between 9 and 15 years of age. Although there is a high awareness of the condom, people are unwilling to use them despite evidence of multiple sexual exposures. The STDs, including HIV infections, are on the increase. Tuberculosis is also on the increase because of a HIV/AIDS epidemic. Both categorical and integrated approach to the management of STDs and AIDS are being recommended. There is a need to step up basic research into the biology of HIV and subsidize the treatment of AIDS. Efforts at vaccine development should be initiated to stem the worsening HIV epidemic. (Af.

Genital ulcer disease in Ilorin, Nigeria
B.A. Onile, Tolu Odugbemi
African Journal of Clinical and Experimental Microbiology , 2002,
Abstract: This is a review of 32 consecutive cases of patients with genital ulcers or who were repeatedly reactive to serological tests for syphilis (STS) at the Venereology Clinic of the University Teaching Hospital, Ilorin, Nigeria, between January 1993 and April 1995. The criteria for diagnosis of the various conditions included the history, clinical presentation and the results of laboratory investigations. The commonest cause of genital ulcers was chancroid, accounting for 6(18.7%) of the 32 cases. Other common causes were lymphogranuloma venereum (LGV), gential herpes and primary syphilis, each acounting for 12.5 percent of the cases. An unusual presentation of oro-genital aphthosis, with hyperkeratosis and paraesthesia of a localized area on the palm, in addition to the usual genital and oral lesions was reported. Also reported were cases of perigenital cutaneous onchocerciasis and a case of leprosy presenting as chronic biological false positive (BFP) to STS. Patients with chancroid responded favourably to treatment with ceftriaxone (Rocephin) and so was the hyperkeratosis of oro-gential aphthosis to topical treatment with flumethasone pivalate/salicylic acid ointment (Locasalen). The importance of histological technique for making the diagnosis of some tropical conditions affecting the genitals was highlighted, and the exercise of caution in interpreting the results of STS was advocated.

Invitro antimicrobial susceptibility pattern of bacterial isolates from wound infections in university of Ilorin Teaching Hospital
S.S. Taiwo, A.B. Okesina, B.A Onile
African Journal of Clinical and Experimental Microbiology , 2002,
Abstract: The outcome of 532 wound swabs received from patients with wound infections in different units of the University of Ilorin Teaching Hospital Ilorin, Nigeria, over a one year period (July 2000 June 2001), and routinely procesed by Gram staining and culture in the Microbiology Laboratory, is reported. 444(83.5) of all samples cultured positive for bacterial pathogens while 88 (16.5%) were bacteriologically sterile. 272 swabs yielded single isolate while 172 yielded a mixture of two or more organisms. Staphylococcus aureus predominates (35.8%), followed by Pseudomonas spp (21.8%), Escherichia coli (15.3%), Klebsiella spp (13.4%), Proteus spp (5.6%), Coagulase Negative Staphylococci (3.1%), Streptococcus faecalis (2.8%), Streptococcs pyogenes (0.9%), Group B _-haemolytic Streptococci (0.9%), and Acinetobacter spp (0.3%). Both Gram-positive and Gram-negative organisms demonstrated moderate to high in vitro sensitivity to Ofloxacin and Ciprofloxacin (sensitivity rate 70-94%). In vitro sensitivity to Cloxacillin, Erythromycin, Azithromycin and Ceftazidime by Gram positive organisms ranged beween 55 and 90% while Gentamicin, Ceftrazidime and Azithromycin equally demonstrated moderate to high inhibitory effect on Gram negative organisms including Pseudomonas spp. (sensitivity rate 55-90%). The Fluoroquino lones are the favoured antimicrobial agents nowadays, as demonstrated in this study. In our environment however, a combination of Cloxacillin and Gentamicin is an effective empiric alternative when cost is considered and this combination can be used. The need for continuous antimicrobial monitoring of clinical isolates of wound infection for drug resistance, which is of paramount importance in the empiric selection of antibiotics, is emphasized.

Chemical Composition of Musa sapientum (Banana) Peels
B.A. Anhwange
Journal of Food Technology , 2013,
Abstract: Musa sapientum peels were analysed for minerals, nutritional and anti-nutritional contents. The result of mineral content indicate the concentrations (mg g 1) of potassium, calcium, sodium, iron, manganese, bromine, rubium, strontium, zirconium and niobium to be 78.10, 19.20, 24.30, 0.61, 76.20, 0.04, 0.21, 0.03, 0.02 and 0.02, respectively. The percentage concentrations of protein, crude lipid, carbohydrate and crude fibre were 0.90, 1.70, 59.00 and 31.70, respectively. The results indicate that if the peels are properly exploited and process, they could be a high-quality and cheap source of carbohydrates and minerals for livestock.
The fish community of the Berg River estuary and an assessment of the likely effects of reduced freshwater inflows
B.A. Bennett
African Zoology , 2012,
Abstract: ENGLISH ABSTRACT: Data concerning the species composition, abundance and distribution of fishes in habiting the Berg River estuary are presented and used to assess the value of the estuary to fish, and the likely effects of reduced freshwater in flows. A total of 31 species was recorded, eight of which were classified as estuarine residents, 11 as marine estuarine-opportunist, six as marine stragglers and six were freshwater species. Liza richardsonii, an opportunist, was the most abundant (54% N) and widely distributed species encountered during the winter and summer seine-net surveys. Three other species (all residents) contributed more than 10% of the total catch; Atherina breviceps and Caffrogobius nudiceps occurring most abundantly in the lower estuary, and Gilchristella estuaria in the middle estuary. The low number of species compared with estuaries in other regions of the South African coast reflect a well-established marine biogeographical trend. The higher proportions of resident species, entirely dependent species and partially dependent species suggest, however, that west coast estuaries may be more important to the fish that inhabit them than are estuaries in other regions. It is concluded that the fish community of the estuary is already suffering the effects of habitat degradation and that further reducation in freshwater inflows are not desirable. ******** AFRIKAANSE OPSOMMING: Data betreffende die spesiessamestelling, talrykheid en verspreiding van visse wat die Bergriviermond bewoon, word aangebied en gebruik in 'n raming van die waarde van die mond vir die bewonende visse, en die moontlike gevolge van verminderde varswaterinvloei. 'n Totaal van 31 spesies is aangeteken, agt waarvan geklassiliseer is as mondinwoners, 11 as mariene trekvisse, ses as mariene swerwers en ses as varswateisoorte. Liza richardsonii, 'n trekvis, was die volopste (54%N ) en mees wydverspreide spesies wat te gekom is gedurende die winter- en someropnames. Die ander spesies (almal inwoners) het meer as 10% bygedra tot die totale vangs, met Atherina breviceps en Caffrogobius nudiceps wat volopste in die laer-, en Gilchristella estuaria in die middelgedeeltes van die strandmeer, voorkom. Die klein aantal spesies weerspie l 'n goed vasgelegde mariene biogeografiese neiging. Die groter proporsie van inwonerspesies, total afhanklike en gedeeltelik afhanklike spesies suggereer egter dat Weskusriviermonde belangrikerr mag wees vir die visse wat hulle bewoon as riviermonde in ander streke. Die gevolgtrekking word gemaak dat die visgemeenskap van die riviermonde reeds on
The Effects of Cooking Time on the Nutritional Parameters of Soya Milk
B.A. Orhevba
American Journal of Food Technology , 2011,
Abstract: In this study, the effect of cooking time on the nutritional quality of soya milk was determined with a view of obtaining the approximate time at which soya milk should be cooked to have its optimum benefit for man. Standard laboratory conditions, methods and instruments were used to obtain the results of the experiments. The soya milk samples were cooked for 15, 30 and 45 min, respectively and there were significant differences in the nutritional composition of soya milk cooked between these time intervals. Soya milk cooked for 15 min was characterized by a moisture content of about 93.45%; ash 4.17%; protein 3.72%; lipids 12.0%; carbohydrates 80.11% and energy value of 443.32 kcal/100 g. On the other hand, the soya milk prepared for 30 min contained moisture content level of 92.29%; lipids 6.48%; energy value of 409.08%, ash 5.83%, crude protein 4.23% and carbohydrates 83.46%. The sample of soya milk prepared for 45 min was characterized by ash content of 6.0%, crude protein 4.74% and lower moisture content 90.36%, lipids 6.17%, carbohydrates 83.09% and energy value of 406.00 kcal/100 g. The minerals investigated gave the following results under treated time of 15, 30 and 45 min, respectively; sodium: 27, 23 and 27 mg/100 mL, potassium: 41, 60 and 62 mg/100 mL, magnesium: 32.2, 31 and 35 ppm and calcium: 109.5, 81 and 90.0 ppm, respectively. It was evident that there were varying degrees of changes that occurred in each of the chemical composition of the soya milk with respect to the different periods of cooking.
Underwater Telemetry as a Tool in Aquaculture Research and Development
B.A. Holand
Modeling, Identification and Control , 1987, DOI: 10.4173/mic.1987.1.2
Abstract: Small acoustical transmitters may be used to obtain data from free swimming fish. The main principles behind this technique are described together with some of the equipment developed. Some examples are briefly discussed where heart beats, depth and temperature are measured to describe fish behaviour. Automatic fish tracking equipment that has been used to track fish within an enclosed area is also described.
Trends in the control of heartwater : tick-borne diseases
B.A. Allsopp
Onderstepoort Journal of Veterinary Research , 2010, DOI: 10.4102/ojvr.v76i1.69
Abstract: Heartwater is an economically serious tick-borne disease of ruminants caused by the intracellular bacterium Ehrlichia ruminantium. The disease has traditionally been controlled by four different approaches : controlling the tick vector by dipping, establishing endemic stability, performing immunisation by infection and treatment, and preventing the disease by regular administration of prophylactic antibiotics. The first three of these methods are subject to failure for various epidemiological reasons, and serious disease outbreaks can occur. Prophylaxis is effective, but very expensive, and the logistics are daunting when large herds of animals are involved. The development of a safe, cheap and effective vaccine is the only likely way in which heartwater can be economically controlled, and over the past 15 years three new types of experimental vaccine have been developed: inactivated, attenuated, and recombinant vaccines. These new vaccines have shown varying degrees of promise, but none is as yet sufficiently successful to be marketable. We describe the experimental products, and the various technical and biological difficulties which are being encountered, and report on ways in which new technologies are being used to improve vaccine effectiveness.
How age affects auditory-cognitive interactions in speech comprehension
B.A. Schneider
Audiology Research , 2011, DOI: 10.4081/audiores.2011.e10
Abstract: To participate effectively in multi-talker conversations, listeners need to do more than simply recognize and repeat speech. They have to keep track of who said what, extract the meaning of each utterance, store it in memory for future use, integrate the incoming information with what each conversational participant has said in the past, and draw on the listener’s own knowledge of the topic under consideration to extract general themes and formulate responses. In other words, to acquire and use the information contained in spoken language requires the smooth and rapid functioning of an integrated system of perceptual and cognitive processes. Here we review evidence indicating that the operation of this integrated system of perceptual and cognitive processes is more easily disrupted in older than in younger adults, especially when there are competing sounds in the auditory scene.
