Induced Proteins Profile In The Haemolymph Of Desert Locust (Schistocerca Gregaria) Following A Trypanosomatid Flagellate (Trypanosoma Brucei Brucei) Challenge

ABSTRACT Innate immunity has a key role in the control of microbial infections in both vertebrates and invertebrates. In insects, including vectors that transmit parasites that cause major diseases such as trypanosomosis, leishmaniasis and filariasis, antimicrobial peptides and agglutinins form an important component of innate immunity and participate in regulating parasite development. In this study, induced haemolymph peptides from a non-vector, nonheamatophagous insect, Schistocerca grega...

Isolation And Purification Of Mosquito Larvicidal Compounds From Extracts Of A Basidiomycete Jo5289

ABSTRACT Mosquitoes present a worldwide, public health and nuisance challenge since they transmit human diseases including west Nile virus, malaria, dengue, Japanese encephalitis, filiarisis and other viral diseases throughout the globe. An obvious method for preventing the spread of these diseases is to control mosquito vector population by insecticides and synthetic agents, which have been developed and employed in the field with considerable success. As a result of insects’ resistance a...

The Spectrum Of Bacteria Causing Urinary Tract Infection Among Pregnant Women Attending Sabasaba Clinic And Their Susceptibility To Antimicrobial Agents

ABSTRACT Urinary tract infections (UTI) during pregnancy can lead to serious obstetric complications, poor maternal and perinatal outcomes. The purpose of this study was to determinethe prevalence of bacterial UTI in pregnant women in Morogoro municipality, Tanzania. This study was conducted at SabaSaba Health Centre from May 2014 to July 2014 involving 196 pregnant women. Mid stream of urine samples were obtained and analyzed by dipstick and processed for culture. Out of 196 pregnant women ...

Dynamic Buckling Of Imperfection- Sensitive Elastic Structures Under Slowly- Varying Time Dependent Loading

ABSTRACT The dynamic buckling loads of some imperfection-sensitive elastic structures subjected to slowly varying time dependent loading are determined using perturbation procedures. First, we consider an elastically imperfect column resting on a softening nonlinear elastic foundation. The governing differential equation has two small parameters. We determine the dynamic buckling load of this column subjected to the stipulated loading for three different cases. The cases are when the small p...

Comparison Of The Susceptibility And Pathology Of Velogenic Newcastle Disease Virus Infection In Broilers And Pullets

ABSTRACT The greatest human nutritional problem in Nigeria is that of inadequate animal protein in the diet of a large proportion of the population. The development and sustenance of the poultry industry in Nigeria appears to be the fastest means of meeting human need for dietary animal protein supply. However, diseases constitute a major problem to the development of the poultry industry and Newcastle disease (ND) is the most important of these diseases. Newcastle disease is caused by ...

Effects Of Npk Fertilizer And Fungicide Application Rates On The Perfomance And Management Of Late Blight (Phytophthora Infestans) In Irish Potatoes (Solanum Tuberosum L)

ABSTRACT Food insecurity has been an issue in developing nations worldwide including Kenya. This is as a result of soil related problems, climate change, crop pests and diseases among food crops. Late blight disease caused by Phytophthora infestans in Irish potato (Solanum tuberosum L) is a major challenge among the small-scale farmers in the highlands of Kenya. Yield losses as a result of late blight in Kenya are about 40 - 50%. The appropriate use of fungicides and fertilizers application r...

A Sedimentologic and Stratigraphic Study of the Maastrichtian-Pateocene Sediments in Yuil Area, Bauchi State

ABSTACT The Maas trichian-Pale ocene sediments in Yuli area me composed of the Gombe Sandstone and the Kerri-Kerri Formation. They cover 400 square kilometres have a thichess of more than 100 metres. Six stratigraphic sections were studied, representing the entire stratigraphic succession of the Gombe Sandstone i n the Yuli area, The formation has a thickness of about 30 metres in the studied area. The Gombe Sandstone consists of folded beds of sandstone, siltstone and mudstone. The sandstone...

Development Of Extruded Instant Mixed Mushroom Soup

EXTENDED ABSTRACT A study was conducted to develop extruded instant mixed mushroom soup supplemented with banana, soybean and orange fleshed sweet potatoes. The nutritional qualities, physical properties, sensory acceptability and the shelf life of the developed product were evaluated. Proximate compositions were determined to evaluate the potential of the product to supply energy and required nutrients. Moisture, ash, protein, fiber, ether extract, carbohydrate and energy content ranged fro...

Prevalence Of Cryptosporidium Species And Giardia Lamblia Infection In Patients Attending Siaya County Referral Hospital, Kenya

ABSTRACT Cryptosporidiosis and giardiasis are common infections in humans in Kenya and Cryptosporidiosis in particular is an opportunistic infection in HIV-infected individuals. Diarrhoeal disease caused by these parasites is a major public health problem particularly in countries with poor socioeconomic status. The study on Cryptosporidium species and Giardia lamblia was carried out in Siaya county referral hospital and was conducted to assess the prevalence and risk factors associated with ...

Evaluation Of The Quality Characteristics Of Wheat - Plantain Composite Flour Bread Containing Gum Arabic From Acacia Senegal Var Kerensis

ABSTRACT The uses of composite flour in bread making are becoming more important as people become health conscious and accept the role of functional foods globally. The effect of partial replacement of wheat with 10% to 40% plantain flour and the subsequent effect of 1% to 3% gum arabic addition on composite bread quality attributes was investigated. It was hypothesized that wheat- plantain flour physicochemical properties did not differ from the control (100% wheat); and that neither substit...

Prevalence Of Bovine Cysticercosis, Taeniasis And Associated Zoonotic Risk Factors In Kajiado County, Kenya.

ABSTRACT Taeniasis is a common zoonosis whose epidemiology is estimated at 50 million cases of infestation worldwide with economic losses in Kenya amounting to $1.289 million by 2003. The infection has been grouped among the neglected tropical diseases thus its impact has been trivialized. A slaughter house survey was undertaken to determine the prevalence rate of bovine cysticercosis in carcasses slaughtered within selected abattoirs in Kajiado County and establish the viability of Cysticerc...
