Commercial Day-Old Chicks in Nigeria Are Potential Reservoirs of Colistin- and Tigecycline-Resistant Potentially Pathogenic .

Frequent use of colistin (COL) and tetracyclines in the Nigerian poultry sector potentially triggers bacterial resistance against COL and tigecycline (TIG), which are last-line antibiotics used to treat multidrug-resistant infections. This study aimed to isolate COL- and TIG-resistant . from commercial day-old chicks distributed to poultry farmers in Nsukka Southeastern Nigeria, assess the production of extended-spectrum β-lactamase (ESBL) and carbapenemase by the isolates, and establish their pathogenic potentials.

Inhibitory effects of macrofungi on experimental benign prostatic hyperplasia in rats.

Objectives: This study was designed to investigate the protective effects of extract on testosterone-induced benign prostatic hyperplasia in rats.

Materials And Methods: In this study, 60 adult Sprague Dawley rats were randomly divided into six equal groups, one group served as the normal control, five of the groups were administered subcutaneous testosterone propionate for 28 days to induce benign prostatic hyperplasia, three of the five groups were simultaneously administered three graded doses of extract while one group was administered finasteride as the standard drug and the other left as untreated BPH model group given testosterone propionate only. BPH in the prostate gland was detected through gross appearance, prostate weight, and biochemical and histopathological analyses.

Epidemiology and Traits of Mobile Colistin Resistance () Gene-Bearing Organisms from Horses.

Mobile colistin resistance () genes (-1 to -10) threaten the efficacy of colistin (COL), a polymyxin antibiotic that is used as a last-line agent for the treatment of deadly infections caused by multidrug-resistant and extensively drug-resistant bacteria in humans and animals. COL has been used for more than 60 years for the prophylactic control and treatment of infections in livestock husbandry but not in horses. Polymyxin B is used for the prophylactic control and empirical treatment of infections in horses without conducting sensitivity tests.

A New Variant of Mutational and Polymorphic Signatures in the Gene of Fluconazole-Resistant .

Background: Resistance to antifungal drugs for treating infections remains a major concern globally despite the range of medications available. Most of these drugs target key proteins essential to the life cycle of the organism. An enzyme essential for fungal cell membrane integrity, lanosterol 14-α demethylase (CYP51), is encoded by the gene in species.

Reduction of the Adverse Impacts of Fungal Mycotoxin on Proximate Composition of Feed and Growth Performance in Broilers by Combined Adsorbents.

Synergistic interaction of adsorbents in reducing the adverse impacts of mycotoxin on performance and proximate composition of broiler feeds was investigated. Fungal growth was induced by sprinkling water on the feed. + bentonite, kaolin + bentonite or + kaolin adsorbent combinations (1.

, bentonite, and kaolin as adsorbents for reducing the adverse impacts of mycotoxin contaminated feed on broiler histopathology and hemato-biochemical changes.

Background And Aim: , bentonite and kaolin were used to reduce the adverse effects of mold-contaminated diet on broilers. The aim of the study was to evaluate the impact of , bentonite, and kaolin in reducing the adverse effects of mold (fungal) contaminated diet on broilers. Specifically, we investigated the histopathological, hematological, and serum biochemical changes associated with broilers fed mold-contaminated diets supplemented with these three adsorbents.

Molecular epidemiology, genetic diversity and antimicrobial resistance of Staphylococcus aureus isolated from chicken and pig carcasses, and carcass handlers.

The epidemiology of Staphylococcus aureus in food animals, associated products, and their zoonotic potential in Nigeria are poorly understood. This study aimed to provide data on the prevalence, genetic characteristics and antimicrobial resistance of S. aureus isolated from chicken and pig carcasses, and persons in contact with the carcasses at slaughterhouses in Nigeria.

Occurrence and antibiogram of species in raw pork, beef, and chicken meats marketed in Enugu State, Southeast Nigeria.

Aim: This study was undertaken to isolate (.) species from raw meats sold in markets in Enugu State, Southeast Nigeria, and to determine the antibacterial resistance profile.

Materials And Methods: Twenty-five grams of beef (n=144), chicken meat (n=144), and pork (n=144) were collected randomly from supermarkets and general markets in Enugu State.

CYPome of the conifer pathogen Heterobasidion irregulare: Inventory, phylogeny, and transcriptional analysis of the response to biocontrol.

The molecular mechanisms underlying the interaction of the pathogen, Heterobasidion annosum s.l., the conifer tree and the biocontrol fungus, Phlebiopsis gigantea have not been fully elucidated.

Analysis of the Phlebiopsis gigantea genome, transcriptome and secretome provides insight into its pioneer colonization strategies of wood.

Collectively classified as white-rot fungi, certain basidiomycetes efficiently degrade the major structural polymers of wood cell walls. A small subset of these Agaricomycetes, exemplified by Phlebiopsis gigantea, is capable of colonizing freshly exposed conifer sapwood despite its high content of extractives, which retards the establishment of other fungal species. The mechanism(s) by which P.

Evolutionary analysis of hydrophobin gene family in two wood-degrading basidiomycetes, Phlebia brevispora and Heterobasidion annosum s.l.

Background: Hydrophobins are small secreted cysteine-rich proteins that play diverse roles during different phases of fungal life cycle. In basidiomycetes, hydrophobin-encoding genes often form large multigene families with up to 40 members. The evolutionary forces driving hydrophobin gene expansion and diversification in basidiomycetes are poorly understood.

Comparative genomics and evolutionary analysis of hydrophobins from three species of wood-degrading fungi.

Hydrophobins are small, secreted proteins playing important roles at different stages of fungal life cycles. Their characteristic feature is the presence of eight highly conserved cysteine residues. Here we present an inventory and evolutionary analysis of hydrophobin genes from three wood-degrading basidiomycetes, Phlebia brevispora, Ganoderma sp.

Expression analysis of the impact of culture filtrates from the biocontrol agent, Phlebiopsis gigantea on the conifer pathogen, Heterobasidion annosum s.s. Transcriptome.

Phlebiopsis gigantea has been routinely used as the biological control agent for the conifer pathogen Heterobasidion annosum sensu lato, but the actual mechanism for the biocontrol process is not known. To investigate the effect of secreted molecules from culture filtrate produced by P. gigantea on the gene expression profile of H.

Differential expression of two hydrophobin genes (Pgh1 and Pgh2) from the biological control agent Phlebiopsis gigantea.

Phlebiopsis gigantea has been widely used as the biocontrol fungus against the root and butt rot disease of conifers caused by Heterobasidion annosum. We investigated the regulation of two hydrophobin genes (Pgh1 and Pgh2) in strong and weak antagonistic isolates of the biological control agent P. gigantea under diverse substrate conditions.
