Plasmid Profile and Multidrug Resistance Pattern of Escherichia coli Isolated from Swine in Abia State

Nwiyi, Paul Okechukwu*

Plasmid is known to play a very vital role in the emergence of multi-drug resistant bacteria in veterinary and human health. A total of 90 isolates of Escherichia coli out of 100 swab samples were recovered from cloacal swabs of swine (neonate, piglet and adults). All the isolates were morphologically and biochemically identified, while 20 of the representative isolates were confirmed using mol...

ERIC-PCR and Protein Patterns of Staphylococcus aureus isolated from Nigerian HIV-Positive Patients Admitted in different Hospitals in Imo State Nigeria

Ijeoma Emeka-Nwabunnia*, Francisca O. Nwaokorie, Viviane Nakano, Mario J. Avila-Campos, Ikechukwu N. E. Onwurah

Opportunistic infections due to endogenous microorganisms have been a global problem in immune compromised Human Immunodeficiency Virus (HIV) positive patients. Staphylococcus aureus is a significant opportunistic pathogen among HIV patients in both nosocomial and community settings. There is scarce information on the relatedness of S. aureus strains isolated from HIV patients in Nigeria. The g...

Determination of Phytochemical and Antimicrobial Activities of Corn Starch Extract on Escherichia Coli and Salmonella Typhi

Erhimu Loveday Obakpororo*, Tasie Floretta, Nwachukwu Ujunwa Felicia, Obodo Chidubem Nathaniel

The phytochemical and antimicrobial effect of cornstarch extracts was investigated. Corn starch of yellow and white corn variety were extracted successively with ethanol, methanol and distilled water. These crude extracts were assessed for antimicrobial activities against Escherichia coli and Salmonella typhi. Escherichia coli were sensitive to the methanolic and ethanolic extracts of white cor...

Nasal Colonization as a Risk Factor for Staphylococcal Infection: a Systematic Review and Meta-Analysis

Shuaibu Suleiman Adeiza*, Josiah Ademola Onaolapo, Busayo Olalekan Olayinka

Staphylococcus aureus (S. aureus) is a gram-positive bacterium found in clinical and community settings across the world. It is a major cause of both nosocomial and community-acquired staphylococcal infections. Nasal carriage rates of S. aureus and Methicillin resistant Staphylococcus aureus (MRSA) among hospital and non hospital centres have been reported in several Nigerian studies. Neverthele...

Itaconic Acid Production by Aspergillus terreus Using Pod of Moringa oleifera as Substrate in Solid State Fermentation

Ajiboye, A.E*, Babatunde, S.K, Adedayo, M.R., Ajuwon, LB, Labinjo, Z.Y

Itaconic acid was produced by Aspergillus terreus under solid-state fermentation using the pod of Moringa oleifera as substrate. Grinded Moringa pod was weighed into separate shake flasks containing salts and Aspergillus terreus (3.2x 104spores/ml) was added. The substrate was left to ferment for 5 days. Carboxylmethylcellulose (CMC) was used as a control substrate. Itaconic acid was assayed us...

Environmental Distribution and Antibiotic Resistance Patterns of Bacterial Isolates from Open Drainage Systems in Port Harcourt, Southern Nigeria

David N Ogbonna*, Rentier R Nrior, Blessing A Erheriene

Bacterial isolates from wastewater and sediments of the Ntanwogba open drainage system in Port Harcourt city was tested for their susceptibility to antibiotics. Wastewater samples were collected twice a week for a period of six months from February through July using standard analytical methods. Results obtained showed that the sediment samples had Escherichia coli with the highest percentage o...

Influence of Environmental and Nutritional Factors on The Vegetative Growth of Pleurotus pulmonarius

Segun Gbolagade JONATHAN*, Fatade Oluwabusola O

Pleurotus pulmonarius is an edible macrofungus that is produced commercially. Cultural studies to determine the most suitable culture media for the vegetative growth was carried out. The effect of environmental and nutritional factors was also investigated. Temperature ranging between 10-25°C and pH values (4.0-8.0) influences was determined on different chemically defined medium (potato dextro...

Seroprevalence of Newcastle Disease Virus from Locally Bred Chicken in Kaduna South Local Government Area. Kaduna State, Nigeria.

Abraham, O. J*, Onwuatuegwu, J.T.C, Nwobodo, A.H., Zakka, A. W., Egbunu, Z. K, Oruma, Y.U, Ahmed, S.f, Ngbo, F. S.

Newcastle disease (ND) is a highly contagious viral disease of domestic poultry, caged, aviary and wild birds caused by the Newcastle disease virus (NDV). Sero prevalence of Newcastle disease virus was determined with 250 sera samples collected from unvaccinated local chickens marketed and slaughtered in Kaduna South Local Government Area, Kaduna State. Northern Nigeria using the Haemagglutinat...

Salmonella Biovars Isolated From Poultry Farms in Abia And Imo States South Eastern Nigeria

Nwiyi, P. O*, Chah, K. F, Shoyinka, V. O.

The aim of this study was to evaluate the biovars of Salmonella that are found in poultry farms in Abia and Imo States, Southeastern Nigeria. Forty Salmonella isolates obtained from previous studies were subjected to molecular identification using the polymerase chain reaction (PCR) with Salmonella universal and species specific primers. Six different Salmonella serotypes were screened to deter...

Susceptibility of Two RNA Viruses of Public Health Significance to Selected Nigerian Medicinal Plants

ObiR.K*, Shenge J.A

Background/Aim: The lack of effective therapies and/or vaccines for several viral infections, and the rapid emergence of new drug-resistant viruses have necessitated the need for developing new and effective antiviral agents. In this study we evaluate the antiviral potentials of three plants indigenous to Nigeria on vaccine strains of Yellow fever virus (YFV) and Polio virus (PV) in order to in...
