ABSTRACT Fresh healthy carrot promote good health but harbour a wide range of contaminants. To assess the microbial quality of carrots sold in Ibadan, a total of fifteen samples were purchased from five vendors. Samples were analyzed to study the density of microorganisms by standard plate count. ...
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...
ABSTRACT Antibacterial activity of honey obtained from two different locations in Enugu State (Nsukka & Ugwuaji) Nigeria on Staphylococcus aureus, Escherichia coli and Streptococcus pyogens isolated from wound was studied. Agar well diffusion method was used to determine the antibacterial activity of the honey on the test microorganisms. The result revealed that the two honey samples have heavy antibacterial activities against the test organisms and zones of inhibition were obtained showing h...
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 A comparative study was done on the physico-chemical and antioxidant properties of some culinary herbs and local spices. Piper Guiness (Uziza), Xylopia aethopica (Uda), Monodora Myristica (Ehuru) and Trtraleura Tetraopera (Oshsho). The proximate analysis of these spices were done to determine their moisture content, ash content, crude fat crude fibre and protein content. Extraction of the Oleorasin from the spices and soybean oil were done using soxhlet extraction unit with h...
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...
ABSTRACT Thirty ripe mango fruits were pluked under sterile conditions from different geographical locations in Enugu metropolis. The mango fruits were exposed to open environment for 5 – 7 days to allow decay. The decaying mango fruits were washed with sterile water to extract the microorganisms. Using the streak plate method, the microorganisms were inoculated unto a petridish of nutrient agar and incubated for 24 hours at room temperature of 250C. A mixture of bacteria, moulds and ...
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...
ABSTRACT Chickenpox is a highly contagious viral illness caused by primary infection with the Varicella zoster virus (VZV). It is characterized by vesicular skin lesions and fever. It causes an itchy rash that looks like tiny blisters. The rash usually starts on the face, stomach, chest or back, and spreads to other parts of the body. A mild fever, tiredness, and slight body discomfort usually come with the rash. Anyone who hasn’t had chickenpox already can get it, but it is most common amo...
ABSTRACT The antibacterial activity of sweet orange(citrus smensin) on staphylococcus aureus and Escherichia coli isolated from would infection was studied. A total number of 100 wound sample were collected form different individual from different age range within 5-8years and examined,. The test organisms S auras and E coli were cultured separately on Nutrient and macconkey agar plate and incubated for 24 hrs at 37)c. the highest isolation of bacterial organisms was obtained in staphylococcu...
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...
