Infection with intestinal parasites is one of the main health issues in poor nations. It is estimated to affect 3.5 billion people worldwide, and 450 million people are thought to be ill as a result of such illnesses, with children making up the majority of those who are ill. By using several stool concentration techniques, this study was aimed at...

The amount of environmental contamination brought on by the careless disposal of plastic garbage has increased to 400 million tons every year on a global scale. These synthetically generated traditional polymers are not easily biodegradable. This work was therefore undertaken to isolate Bacillus subtilis from soil with potential to produce bioplast...

This work concentrated on the isolation of lead tolerant strains of bacteria, identification of the isolated strain with the highest lead tolerance capacity using microgen identification kit.

This study characterized multi-drug resistant M. tuberculosis phenotypically by the LJ-proportion method and genotypically by GenoType MTBDR plus LPA. Out of the forty M. tuberculosis isolates tested, two (5.0%) were found to be multi-drug resistant by the LJ proportion method and one (2.5%) was MDR by LPA. None was found to be mono-resistant to an...

The problem of tuberculosis (TB) in Nigeria has been made worse by the issues of drug resistant Mycobacterium tuberculosis. Resistance associated with treatment failures has become a common occurrence worldwide. Of particular concern is the increasing prevalence of multi drug resistant M. tuberculosis; organisms resistant to isoniazid and rifamp...

Biofilm producing bacteria are associated with many recalcitrant infections and are highly resistant to antimicrobial agents, hence notoriously difficult to eradicate. This study aimed at determining the biofilm forming capacities of bacterial isolates recovered in the raw wastewater and treated effluent from Wastewater Treatment Plants of Ahmadu B...

To control and prevent poultry diseases, breeders are known to administer subtherapeutic and therapeutic levels of antimicrobial agents to chickens via feed and water, which improves feed efficiency and accelerates weight gain but provides a selective pressure for antibacterial resistance. This study was aimed at evaluating the rational use of anti...

Industrial effluent causes serious problem to the environment, it contain toxic chemicals such as heavy metals, dyes and other substances which affect water bodies, soil and other parts of the ecosystem. Heavy metals such as Lead (Pb), Cadmium (Cd), Chromium (Cr) and Copper (Cu) are very hazardous to human life, when released through human anthropo...

Sugarcane bagasse is an agro-waste produced by sugar industries and can be burnt to generate energy in sugar and ethanol mills, which in turn causes environmental pollution. This residue from sugar industries is rich in complex materials and can be used for the growth of fungal species. The aim of the present work was to evaluate the potential of s...

Large volume of wastewater is generated by tannery industry, which contains heavy metals such as Chromium, Cadmium, Lead, Copper, Zinc, Mercury and Arsenic. Chromium (Cr) is one of the common and toxic heavy metal pollutants released by industries in their effluent. In this study, tannery effluent was collected from Challawa industrial estate, Kano...

The in vitro antimicrobial activities of ethanol extracts of ginger (Zingiber officinale), garlic (Allium sativum) and clove (Syzygium aromaticum) were evaluated against some bacteria (Staphylococcus aureus and Escherichia coli) and moulds (Aspergillus niger and Rhizopus stolonifer) isolated from food samples by agar well diffusion method and poiso...

In this study, the possibility of using tomato juice as an alternative medium for growing fungi was tested. Four isolates; Penicillium sp., Aspergillus sp., Fusarium sp. and Candida sp. were inoculated on Tomato Juice Agar (TJA), Tomato Juice Agar supplemented with 1g of glucose (TJA+1g Glc), Tomato Juice Agar supplemented with 2g of glucose (TJA +...

This study was conducted to determine the antimicrobial and synergistic activity of honey and ginger extracts on Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA).Agar well diffusion method was used to determine susceptibility of the test organisms using honey and ginger extracts individually, and the Minimum Inhibitory...

This study was aimed at evaluating the efficacy of three (3) different commercial disinfectants commonly used in some selected Hospitals laboratories in Sokoto metropolis, the disinfectant preparations were investigated against Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi by using tube dilution and agar diffusion methods respe...

Abstract This study was designed to assess the potential risk of transmitting E. coli O157:H7 through vegetables. Suspensions (25g of vegetable in 225ml of distilled water) of 100 vegetables, 20 each of spinach, carrot, cabbage, lettuce and tomatoes were separately cultured on Eosine Methylene Blue Agar (EMBA) for the viable count and isolation of...

Diarrheal disease is a global public health problem causing considerable morbidity and mortality among infants and children especially in the developing countries. Acute diarrhea due to Escherichia coli infections is an important cause of Morbidity and mortality in infants and young children in most developing countries including Nigeria. The aim o...

The study was carried out to compare the the production capabilities and the biosurfactant activity of the bacteria, Bacillus subtilis and Pseudomonas aeruginosa using engine oil and diesel as the substrate respectively. The test organisms were isolated from engine oil contaminated soil as in the case of the Bacillus subtilis, which was collected f...

The antibacterial potency of aqueous and methanol extracts of garlic was determined invitro against three bacterial isolates (Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa) by agar well diffusion method. Preliminary phytochemical screening revealed the presence of tannin, flavonoid, carbohydrate, protein, saponin, alkaloid and...

This study was carried out to evaluate the microbiological quality and nutritional values of sliced fruits vended in some parts of Kano metropolis, northern Nigeria. Two hundred and forty (240) sliced fruit samples comprising of pineapple (60), pawpaw (60), water melon (60) and coconut (60) purchased at the point of sales were analyzed using standa...
