Incidence and Virulence Factor Profiling of Species: A Study on Hospital and Community Wastewater Effluents.

This study aimed to determine the incidence and virulence factor profiling of species from hospital wastewater (HWW) and community wastewater effluents. Wastewater samples from selected sites were collected, processed, and analysed presumptively by the culture dependent methods and molecular techniques. A total of 270 isolates were confirmed as genus delineating into (27%), (9.

Molecular Characterization and Antibiotic Susceptibility Profile of Acinetobacter baumannii Recovered from Hospital Wastewater Effluents.

Acinetobacter baumannii (A. baumannii) plays a significant part in nosocomial infections world over and is re-emerging as a formidable pathogen due to the wide range of antibiotic resistance factors it acquires and environmental resilience. The high attendance of patients (outpatients and inpatients) into the health care facilities formed the basis for the selection of the hospitals.

Virulence and Antibiotic Resistance Characteristics of Isolates From Rustic Environmental Freshwaters.

The study investigated the occurrence of antimicrobial resistance genes and virulence determinants in species recovered from different freshwater sheds in rustic milieu. A total of 118 isolates comprising (n=41), (n=40) and (n=37) was identified by amplification of , and genes. The amplification of virulence genes indicated that .

keratinase liberated essential and nonessential amino acids from chicken feather degradation.

Keratinous biomass valorization for value-added products presents a high prospect in ecological management and the advancement of the bio-economy. Consequently, soil samples from the poultry dumpsite were collected. The bacteria isolated on the basal salt medium were screened for keratinolytic activity.

Characterization of a thermostable and solvent-tolerant laccase produced by Streptomyces sp. LAO.

Objectives: Decaying wood samples were collected, and actinomycetes were isolated and screened for laccase production. The identity of the efficient laccase-producing isolate was confirmed by using a molecular approach. Fermentation conditions for laccase production were optimized, and laccase biochemical properties were studied.

Chemokine Coreceptor Usage Among HIV-1 Drug-Naive Patients Residing in the Rural Eastern Cape, South Africa.

Sub-Saharan region in Africa still holds the highest burden of HIV/AIDS globally. HIV-1 requires coreceptor to gain entry into permissive cells to initiate infection. Molecular analysis of the chemokine coreceptor usage is important clinically and in the effective management of AIDS virus.

Molecular Genetics and the Incidence of Transmitted Drug Resistance Among Pre-Treatment HIV-1 Infected Patients in the Eastern Cape, South Africa.

Background: Transmitted drug resistance (TDR) remains a significant threat to Human immunodeficiency virus (HIV) infected patients that are not exposed to antiretroviral treatment. Although, combined antiretroviral therapy (cART) has reduced deaths among infected individuals, emergence of drug resistance is gradually on rise.

Objective: To determine the drug resistance mutations and subtypes of HIV-1 among pre-treatment patients in the Eastern Cape of South Africa.
