Reports about ringworm in donkeys are scanty and refer to zoonotic agents such as Trichophyton mentagrophytes and Trichophyton verrucosum. Seventeen Asino Amiatina donkeys semi-extensively farmed in paddocks showed alopecic nummular, scaling areas mainly on head and neck. Microsporum racemosum cultivated from the lesions was identified by morphology and PCR. Affected animals healed spontaneously. The present record reports for the first time the occurrence of ringworm due to M. racemosum in naturally infected animals.

Phylogenetic studies of the family Arthrodermataceae have revealed seven monophyletic dermatophyte clades representing the genera Trichophyton, Epidermophyton, Nannizzia, Lophophyton, Paraphyton, Microsporum, and Arthroderma. Members of the genus Nannizzia are geo- or zoophiles that occasionally infect humans. With the newly proposed taxonomy, the genus Nannizzia comprises thirteen species, i.

Previously, seventeen 2-phenoxy-benzo[g][1,2,4]triazolo[1,5-a]quinazoline derivatives were prepared and characterized by physicochemical and spectral means. This study was conducted to evaluate their activities in vitro against five Gram-negative and five Gram-positive of clinically pathogenic bacterial strains and ten fungal strains. The antimicrobial activity was assessed, and the minimum inhibitory concentration values of the tested compounds were determined in μg ml, using the diffusion agar technique.

Background: The antimicrobial activity of a synthesized series of 28 2-thioxobenzo[ g]quinazolin-4(3H)-one derivatives was evaluated in vitro against five Gram-positive bacteria, including Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus pyogenes. The antibacterial activity was extended to include five Gramnegative bacteria: Pseudomonas aeruginosa, Escherichia coli, Proteus mirabilis, Klebsiella oxytoca and Enterobacter cloacae. Furthermore, the antifungal activity was evaluated against 10 fungal strains, including Aspergillus fumigatus, Syncephalastrum racemosum, Geotricum candidum, Candida albicans, Aspergillus niger, Cryptococcus neoformans, Candida tropicalis, Penicillium expansum, Microsporum canis and Trichophyton mentagrophytes.

Background: The present study was carried out to evaluate the antimicrobial activity of a synthesized 2-methylthio-benzo[g][1,2,4]triazolo[1,5- a]quinazoline series. The compounds (1-21) were tested against a variety of Gram-positive bacterial species including Bacillus subtilis (RCMB 01001 69-3), Enterococcus faecalis (RCMB 0100154-2), Staphylococcus aureus (RCMB 0100183-9), Staphylococcus epidermidis (RCMB 0100183-9) and Streptococcus pyogenes (RCMB 0100172-5). In addition, Gram-negative bacteria were also tested including Pseudomonas aeruginosa (RCMB 0100243-5), Escherichia coli (RCMB 010052-6), Proteus mirabilis (RCMB 01002 54-2), Klebsiella oxytoca (RCMB 01002 83-4) and Enterobacter cloacae (RCMB 01002 64-5).
