A cross sectional study was conducted from February to May 2017 to investigate the prevalence of abomasal nematodes infection and to assess the relationship between the occurrence of these parasites and factors of age, sex, locality, body condition and breed in slaughtered sheep in Khartoum State, Sudan. A total of 350 abomasi were collected from three slaughterhouses namely: Karary, Nasr eldeen and Sabaloga in Karary, East Nile and Umbada localities respectively, and examined using pos...
ABSTRACT Bedbugs are blood-sucking insects of the order Hemiptera and family Cimicidae that derive nutrition from vertebrates, including humans, their feeding is allied to the transmitting several fungal, bacterial and viral infections. A rise in international travels and emergence of insecticide resistant bedbugs within the past decade has led to renewed interest in studying these insects. Anecdotally, bedbugs exist in homes, boarding houses, hotels and other human dwellings in Ghana but hav...
ABSTRACT Background: Dengue and malaria are two important mosquito-borne diseases. Together, both diseases are indistinguishable due to similarities in clinical and laboratory characteristics. These similarities have contributed immensely to the overdiagnosis of malaria and the under-recognition of dengue in many countries in subSaharan Africa. No baseline study has yet been conducted in Ghana to estimate the burden of dengue. This study therefore set out to estimate the prevalence of dengue ...

INTRODUCTIONChlamydiae are small gram-negative obligate intracellular microorganisms that preferentially infect squamocolumnar epithelial cell (www. Google. Com.2010). Chlamydia is the most prevalent sexually transmitted disease resulting in urethritis, with frequencies exceeding those of Neisseria gonorrhoeae. In the United State for instance, roughly four million cases are reported annually mostly occurring in men and women under the age of 25 (Barners, 1990). In Nigeria and indeed most ...
Logistic regression model deals with the relationship that exists between a dependent variable and one or more independent variables. It provides a method for modeling a binary response variable, which takes values 1 and 0. Further, Logistic regression is useful for situations in which you want to be able to predict the presence or absence of a characteristic or outcome based on values of a set of predictor variables. It is similar to a linear regression model but is suited to models where th...
ABSTRACT Inflation Targeting as a monetary policy has been adopted widely by many countries both developed and developing. The Bank of Ghana, adopted Inflation Targeting in 2002 but made an official announcement of its use in 2007, making Ghana the second country to adopt Inflation Targeting in Africa after South Africa. This study sought to determine the effects of Inflation Targeting on the Inflation Rate, Economic Growth, the Exchange Rate and the growth in Money Supply of Ghana. The study...
Abstract Background Grains of important food and export crops in Africa are susceptible to contamination by toxin-producing moulds. Aflatoxins are mycotoxins associated with liver damage and cancer in humans and animals. These toxic substances are produced by fungi (such as Aspergillus flavus and Aspergillus parasiticus) in food and feed exposed to poor conditions during crop cultivation, storage or processing of harvest. The presence of aflatoxins in especially maize and peanuts in Kenya is...
Abstract: In agricultural ecosystems, insect pests, pathogens, weather patterns, and reduced soil fertility pose major challenges to crop productivity and are responsible for significant yield losses worldwide. Iris yellow spot virus (IYSV) vectored by Thrips tabaci Lindeman,is a major hindrance to onion production in eastern Africa. Control measures often rely on insecticides with deleterious effects. Endophytes are one key alternative as they can play important roles in mediating induced s...
ABSTRACT Microbial examination of spoilt Avocado fruits was carried out to obtained the causal organism. A total of 60 avocado from Ogbete Main market and New market Enugu were examined by culturing on nutrient agar and sabourand dextrose agar (SM), for bacteria and fungi causing post – harvest spoilage on the fruits; six bacterial species and six fungal species were isolated. The bacteria include Erwinia SP (66.7%), Streptococcus sp, *25%), E. Coli (18.9%) and staphycoccus sp (33.3...
