Clinical Fusariosis in India: Taxonomy, Pathogenesis, and Therapeutic Challenges
Abstract: Fusarium species are emerging opportunistic pathogens in humans, responsible for a wide spectrum of infections ranging from superficial keratitis and onychomycosis to life-threatening disseminated disease in immunocompromised hosts. Historically regarded as plant pathogens and environmental saprophytes, these hyaline moulds have become clinically relevant with the increasing use of intensive chemotherapy, haematopoietic stemcell and solidorgan transplantation, and widespread use of broadspectrum antibiotics and corticosteroids. In India, Fusarium assumes particular importance due …

Curvularia spp. and Curvularia Infections: A Comprehensive Review
Abstract: Curvularia spp., dematiaceous (melanin-pigmented) fungi in the family Pleosporaceae, emerge as opportunistic pathogens that cause phaeohyphomycosis, allergic fungal rhinosinusitis, and keratitis. This review dissects their pathogenesis via melanized cell walls, conferring tissue invasion, protease secretion, and immune evasion in immunocompromised hosts. Clinical manifestations span cutaneous (70%), sinopulmonary (20%), disseminated (5-10%), and CNS forms, mimicking aspergillosis or mucormycosis. Laboratory diagnosis hinges on histopathology (irregular septate hyphae, 3-8 µm, brown on Fontana-Masson), …

UV Induced Increase in Activity of Subtilisin from Bacillus subtilis MTCC441
Abstract: Microorganisms are constantly exposed to varying physical, chemical and biological conditions which induce morphological, biochemical and genetic changes in them. These changes may be deleterious to some organisms whereas others develop mechanisms to overcome such stresses. This study was conducted to understand the microbiological and biochemical changes in bacteria under conditions of UV stress. Bacillus subtilis MTCC441, a ubiquitous, spore forming bacterium was chosen as the model organism for this …

Frequency and Effect of CCR5 Alleles on HIV-1 Disease Progression among Untreated Seropositive Individuals Visiting Gondar University Teaching Hospital
Abstract: Abstract:The natural history of HIV-1 infection varies considerably from one individual to another, with some individuals progressing to AIDS rapidly after primary infection, while others remain clinically asymptomatic with no evidence of immune dysfunction. Recent studies have shown that reasons for progression and non-progression are multi-factorial and may involve genetic, virological and immunological factors that influence HIV disease progression in various ways. Chemokine receptors act as important co-receptors mediating the …

Biochemical, Antimicrobial Characterization of Dooars Tea (Camellia sinensis) Clone during CTC Manufacturing
Abstract: Industrial manufacturing of CTC tea includes different stages. The polyphenol content catechins are oxidized from stage 1–4 (including withering, cutting/tearing, fermentation/oxidation and drying processes). The catechins are polymerized to tannins with the help of enzyme polyphenol oxidase (PPO), both classes of compounds show differential antioxidant (total flavonoid content, UV absorbing compounds content, antioxidant enzyme Phenylalanine ammonia lyase activity is changed), antimicrobial and therapeutic potentials, usually reduced in late (dried) stages. …

Impact of PPAR-γ2 pro12Ala Gene Polymorphism and Susceptibility of Type 2 Diabetes Mellitus in Patients Visiting Gondar University Teaching Hospital
Abstract: Type 2 diabetes mellitus (T2DM) is characterized by hyperglycemia that can occur through mechanisms such as; impaired insulin secretion, insulin resistance in peripheral tissues and increased glucose output by liver. Type 2 diabetes clearly represents a multifactorial disease, and several findings indicate that multiple genetic and environmental factors are important contributing factor involved in the pathogenesis of this disease. Recently great emphasis has been given to genetical factors to combat …

Potentiality of Bacteriocins as the Attachment Inhibitors of HIV-1 gp120
Abstract: It is postulated that some bacteriocin derivatives are consummate candidates to inhibit the binding of HIV gp120 to CD4 T-cell. From the discovery of bacteriocin compounds in 1925 and forth, nearly 300 bacteriocins have been identified. Of various bacteriocins, there are some which have been used successfully for inhibiting both animal and human pathogens. Unfortunately, no large extent research has been found in the development of various bacteriocins as HIV …
