The determination of prevalence and antibiotic sensitivity pattern of MRSA will help the treating clinicians for first line treatment in referral hospitals.
Totally 25 marine soil samples were collected from the region of Palk Strait of Bay of Bengal, Tamil Nadu, and were subjected to the isolation of actinomycetes. Sixty-eight morphologically distinct isolates were obtained and 37% (25) of them had antimicrobial activity. The potential producer was named as Streptomyces sp. VPTS3-1 and the phylogenetic evaluation on the basis of 16S rDNA sequence further categorized the organism as Streptomyces afghaniensis VPTS3-1. Further, the antimicrobial compound was extracted from the isolate using various solvents and the antimicrobial efficacies were tested against bacterial and fungal pathogens. In addition, in vitro optimization of parameters for the antimicrobial compound production revealed that the suitable pH as 7-8, the period of incubation as 9 days, temperature (30°C), salinity (2%), and starch and KNO 3 as the suitable carbon and nitrogen sources respectively in starch-casein medium.
We report a case of a 59-year-old male patient with a postoperative fungal infection of the left eye. A dark-pigmented yeast, Exophiala dermatitidis (previously known as Wangiella dermatitidis), was identified from the culture of the biopsy taken from the posterior capsule. The infection was successfully eradicated by a combination of surgical and medical (i.e., voriconazole and fluconazole) treatment. This is the first report of successfully treated E. dermatitidis endophthalmitis, which demonstrates that a prompt and aggressive antifungal therapy combined with surgical intervention is necessary to prevent vision loss in cases of endophthalmitis due to Exophiala species. Beside the case description, we also aim to provide a literature review of previously reported eye infections caused by Exophiala species in order to help the future diagnosis and management of the disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
