Abstract: The virulence of eight isolates of Metarhizium anisopliae and four isolates of Beauveria bassiana (Ascomycota: Hypocreales) to adult Cylas puncticollis (Coleoptera: Curculionidae) was tested in the laboratory. Insects were sprayed with a standard concentration of 1.0 107 conidia mL21 using Burgerjon’s spray tower. All the isolates tested were pathogenic to C. puncticollis. Mortality varied between 77.5% and 84.2% with isolates of B. bassiana and between 62.5% and 89.2% with isola...
INTRODUCTION There has been world wide explosion of infectious diseases with emerging diseases such as HIV/AIDS pandemic as well as old diseases like cholera, tuberculosis, dengue, or malaria. These infectious diseases are on a sudden increase due to many factors amongst which; climate change, transformation of ecosystems, socio-economic problems and Public health systems deterioration in many countries in the world. Generally, numerous diseases have emerged and re-emerged (Sanjeev et al., 20...
This seminar report provides an in-depth examination of the microorganisms causing soft rot of tomato. Tomato (Solanum lycopersicum) is a red edible fruit having many varieties which are widely grown, often in greenhouses in cooler climates and open fields. It is consumed in diverse ways, including raw, as an ingredient in many dishes and sauces, in drinks and as a vegetable for culinary purposes. Diseases are a major limiting factor for tomato production. Diseases can be classified into two ...
Abstract: Nosemosis is a parasitic disease caused by microsporidian pathogens of the genus Nosema infecting both the Western honey bee, Apis mellifera, and the Asian honey bee Apis cerana. The disease may adversely affect bee colonies and eventually result in high losses in apiculture and agriculture. We determined the Nosema species infecting honey bees and their prevalence in two islands of the Comoros Archipelago (Grande Comore (GCO) and Mohéli (MOH)) in the Southwest Indian Ocean. In Co...
ABSTRACT Livestock production is one of the farming systems and has a great impact on food and economic security in most developing countries. Animal African trypanosomiasis is a major limitation to livestock production in Africa, particularly cattle production. The disease is caused by Trypanosoma spp., a broad range of protozoan parasites of wild and domestic animals through cyclical and mechanical transmission. Cross-sectional studies conducted in Ghana reveal the common species of trypano...
Abstract: In the past few decades, the control of pests and diseases of cultivated plants using natural and biological measures has drawn increasing attention in the quest to reduce the level of dependence on chemical products for agricultural production. The use of living organisms, predators, parasitoids, and microorganisms, such as viruses, bacteria, and fungi, has proven to be a viable and sustainable pest management technique. Among the aforementioned, fungi, most importantly the insect...
ABSTRACT This study was conducted to document the occurrence and characteristics of mycotic agents isolated from trade horses and donkeys in Obollo-Afor, Enugu State. A total of 497 horses and 65 donkeys presented for sale at Obollo-Afor horse/donkey market during the wet season (June to August 2014) and dry season (January to March 2015) were examined for skin lesions. For each horse/donkey examined, the location of skin lesion as well as the sex of the animal was recorded. Each skin lesion...
ABSTRACT Background Nosocomial infections are a major public health problem worldwide and are on the increase despite significant efforts by hospital infection control measures. Nosocomial infection comprises infection occurring in a patient who is receiving treatment in a health care settings. Infection acquired by health care workers and people visiting the hospital is considered nosocomial infection. These infections affect about 2 million people globally resulting in 5% to 15% of them sp...
Abstract: Many microorganisms have the potential to cause diseases for which the human body is prone. The discovery of antibiotics has, however, provided important tools to combat bacterial diseases. But due to the indiscriminate use of commercial antimicrobial drugs in the treatment of infectious diseases multiple drug resistance has developed among some pathogens. This creates a need for searching new effective and safe antimicrobial therapeutic agents. The aim of this study was to test th...
Abstract: Intestinal protozoan parasites are among the most common human infections globally. They are distributed throughout the world with high prevalence rates especially in developing countries including Ethiopia. This study was conducted to assess the prevalence of intestinal protozoan parasitic infections among School children and their associations with parasitological quality of water sources in Gursum Woreda, eastern Ethiopia. The design of the study was a descriptive cross-sectiona...

ABSTRACT Human systemic fungal infections have increased in the past decade due to the dramatic increase in immunocompromised patients hence the emergence of resistant fungal strains. It is therefore necessary to discover new antifungal compounds with novel mode of action. This study was aimed at isolating and characterizing antifungal agents from wood decaying fungi (WDF). The growth conditions for maximum production of bioactive agents from WDF were first tested. It was observed that miner...
Abstract Concern about the spread of infections in the hospital setting has prompted regulatory agencies to mandate infection control standards. Each hospital department is required to have written policies and procedures which describe measures to prevent and control the spread of infections (hospital acquired infections), along with quality assurance programs to assure that procedures are followed. The Department of Nuclear Medicine, as other departments, should have procedures which addr...
Abstract: Globally, orange is one of the major fruit crops contributing to nutrition and monetary income. False codling moth (FCM), Thaumatotibia leucotreta, is one of the major constraints of orange production. Before this study, little was known regarding the bioecology of FCM in orange and vegetables in Kenya and Tanzania and the potential use of dry conidia of entomopathogenic fungi for control of T. leucotreta moths has not been tested. There is also no IPM strategy available for FCM in...
ABSTRACT Cryptococcus is the most incriminated fungal pathogen that causes cryptococcal meningitis in HIV-infected patients and is known to constitute a major cause of mortality in AIDS patients. Previous studies, mostly from Africa have indicated that positive serum cryptococcus may precede the development of cryptococcal meningitis and cause early mortality among patients with advanced HIV infection. There is no published data on the burden of cryptococcal infections among HIV patients in ...
