ABSTRACT With the ongoing adverse effects of using Chemical fertilizers to both the plants, human and animal life, it has become imperative to seek an alternative to this menace. A biofertilizer is a substance which contains living microorganisms which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Some common agents in biofe...
Abstract Despite the early success demonstrated with the hepatitis B vaccine, no other recombinant engineered vaccine has been approved for use in humans. It is unlikely that a recombinant vaccine will be developed to replace an existing licensed human vaccine with a proven record of safety and efficacy. This is due to the economic reality of making vaccines for human use. Genetically engineered subunit vaccines are more costly to manufacture than conventional vaccines, since the antigen must...

Chlamydia infection, often simply known as Chlamydia, is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis.
ABSTRACT The bacteriological quality of snacks and beverages locally produced in RUGIPO were investigated using Standard Microbiological methods. The total bacterial density ranged between 36-49x103cfu/ml, the total coliform count ranged between 5-12x103 and the total yeast/mould count ranged between 6-23x103. A total of nine bacterial genera; E. Coli, Bacillu sp., Enterococcus sp., Enterobacter sp., Klebsilla sp., Proteus sp., Micrococcus sp., and Salmonella sp while a total four mould...
Effect of pesticides on soil and microorganisms benefitting the soil and degradation.
ABSTRACT Erythromycin is antibiotics produced from a strain ofStreptomyces erythreus (later changed to "Saccharopolyspora erythraea") which belongs to the group of macrolides which tends to inhibit the growth/development of bacteria. It sometimes exhibits bactericidal characteristics when administered in high concentration. It carries out its bacteriostatic actions by binding to the 23s RNA component of the 50s ribosome of the bacteria, thereby interfering with the assembly of the 50...
Virus is transmitted by infected mosquitoes that act as vectors to infect individuals during a mosquito bite. The viruses are not reported to be transmitted from person to person, although theoretically this could happen in some rare instances (blood transfusions, organ transplants, sexual contact, and from mother to fetus). Some investigators suggest that transfer of Zika virus may be transmitted by sexual contact more frequently than first suspected, thus providing another way the virus ...
ABSTRACTGastro Intestinal Helminthiasis was investigated among primary school children in Ihengwu village, Oko between February and March 2015. Sixty samples of freshly collected faeces from sixty randomly selected primary school children between the age of four and ten years from two selected primary schools; Gaius Benton and Pope John primary schools, Oko were analyzed. A small quantity of each faecal sample was collected from the specimen bottle and emulsified on a clean microscopic slide ...
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...
