ABSTRACT Entrohemorrhagic Escherichia coli O157:H7 is a major food borne pathogen causing severe disease in humans worldwide. Healthy cattle are the reservoir of Escherichia coli O157:H7, and bovine food products and fresh produce contaminated with bovine waste are the most common source for disease out breaks in the United States. Escherichia coli O157:H7 also survives well in the environment. The abilities to cause human disease, colonize the bovine gastrointestinal tract, and require tha...
INTRODUCTION Ugba also called ukpaka is a popular food delicacy in Nigeria especially among Ibo ethnic group. It is rich in protein and is obtained by a solid state fermentation of the seed of African oil bean tree (Pentaclethra macrophylla Benth). It is essential food item from various traditional ceremonies where it is mixed with slices of boiled stock fish (ugba and okpoloko). The natural fermentation of the seed which at present is still done at the house-hold level, renders the product...
ABSTRACT Despite more than 100 years of research since the discovery of malaria parasite in human blood, it still remains one of the most common vector-borne diseases widespread in tropical and subtropical regions and constituting a major global health problem. This deadly parasitic disease is caused by the plasmodial parasite species which is vectored by female Anopheles mosquito and can be transmitted to people of all ages. From Quinine to Artemisinin Combination Therapy (ACT), antimalarial...
ABSTRACT Anthrax is an infection caused by the bacterium Bacillus anthracis. its symptoms begin between one day and two months after contracting the infection. Anthrax is spread by contact with the spores of the bacteria, which are often from infectious animal products. Contact is by breathing, eating, or through an area of broken skin. It does not typically spread directly between people. Risk factors include people who work with animals or animal products, travelers, postal workers, ...
Food poisoning syndrome results from ingestion of water and wild variety of food contaminated with pathogenic organisms (bacteria) and their toxins. Food poisoning must be suspected when an acute illness with gastrointestinal or neurological manifestation affect two or more persons or animals who have share a meal during the previous 24 to 72 hours. The term generally used encompasses both food related infection and food related intoxication. Food borne illness (FBI) often called food ...
SECTION 1 1.0 Introduction Aspergillus species are ubiquitous opportunistic moulds that cause both allergic and invasive syndromes. The genus comprises approximately 180 species, of which 33 have been associated with human disease. Most infections are caused by Aspergillus fumigatus, Aspergillus flavus, Aspergillus terreus, and Aspergillus niger (Lee J.Y., et al. 2001). Less commonly, Aspergillus nidulans can be implicated as the causative pathogen, especially in the setti...

INTRODUCTION The Millennium Summit in September 2000 and held in New York City was described as the largest gathering of global leaders in history. The three-day summit was one where 149 global leaders gathered on the table of brotherhood. Three days after, the leaders arrived at the Millennium Declaration which automatically became known as the Millennium Development Goals (MDGs). The millennium development goals (MDGs) is a set of eight point agenda adopted by all member states includ...
INTRODUCTION The term probiotic (opposite of antibiotics) is used when we refer to bacteria associated with beneficial effects on humans and animals. It was invented in the early twentieth century by Nobel Prize winner, Eli Metchnikoff, and introduced in his study, the prolongation of Life. (Metchnikoff, 1907).Metchnikoff has shown since 1907 that Lactobacillus bulgaricus is able to eliminate pathogenic bacteria from the intestinal microflora. The actual introduction of the concept belongs to...
INTRODUCTION DEFINITION AND HISTORY Bacteriocins are bacterial ribosomally synthesized peptides or proteins with antimicrobial activity. As ribosomally synthesised peptides, bacteriocins are encoded by a plasmid- or chromosome-borne structural gene which is often clustered with genes coding for immunity protein(s) and dedicated transport. Bacteriocins are proteinaceous toxins produced as a tiny molecule by bacteria to inhibit the growth of similar or closely related bacterial strain(s) produc...
INTRODUCTION Mycotoxins are pharmacologically active mold metabolites produced in a strain-specific way that elicit some complicated toxicological activities (Bennett, 2003). Mycotoxins could also be described as secondary metabolites produced by a wide variety of organisms categorized as fungi, including mushrooms, yeasts and molds. The term mycotoxin was used for the first time in 1961 in the aftermath of a veterinary crisis in England, during which thousands of animals died. The disease wa...
INTRODUCTION A fungus is any member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, Fungi, which are separate from plants, animals, protists, and bacteria. One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants and some protists, which contain cellulose, and unlike the cell walls of bacteria. These and ot...
ABSTRACT Nitric oxide is produced in high amount from the break down of arginine by a group of enzyme called nitric oxide synthase. Nitric oxide is an intercellular messenger that has been recognized as one of the versatile player in the immune system. Cells of the innate immune system such as macrophages, neutrophil and natural killer use pattern recognition receptors to recognize the molecular patters associated with pathogens. The specific role nitric oxide plays depend on the place of i...
INTRODUCTION Jock itch gets its name because it is common in people who sweat a lot, majorly the athletes. It is also more likely to occur in people who are overweight. Although often uncomfortable and bothersome, jock itch usually is not serious. Jock itch (tinea cruris) is a fungal infection that affects the skin of the genitals, inner thighs and buttocks. Jock itch causes an itchy, red, often ring-shaped rash in these warm, moist areas of the body. groin area clean and dry and applying t...
INTRODUCTION Agricultural microbiology is a branch of microbiology dealing with plant-associated microbes and plant and animal diseases. It also deals with the microbiology of soil fertility, such as microbial degradation of organic matter and soil nutrient transformations. Agricultural microbiology is a scientific discipline oriented to satisfy the request of new knowledge from the society, consumers and producers, needed for the exploitation of microbial resources in the main frame of agric...
