Drug-resistant Acinetobacter baumannii-calcoaceticus complex, Klebsiella pneumoniae, and methicillin-resistant Staphylococcus aureus colonize and infect combat casualties from Iraq and Afghanistan. We retrospectively evaluated relatedness, by pulsed-field gel electrophoresis and antibiotic susceptibility testing, of isolates colonizing and infecting casualties over 2 years. Colonizing organisms...

D-gluconate which is primarily catabolized via the Entner-Doudoroff (ED) pathway, has been implicated as being important for colonization of the streptomycin-treated mouse large intestine by Escherichia coli MG1655, a human commensal strain. In the present study, we report that an MG1655 Deltaedd mutant defective in the ED pathway grows poorly not only on gluconate as a sole carbon source but o...

Ocimum tenuiflorum, O. gratissimum, and basilicum are medicinal plants extensively used in the traditional medicine of Kerala. The study is aimed at investigating endophytic mycoflora associated with these species their ability to produce enzymes vitro. A total 149 fungal endophytes were isolated from roots, stems, leaf segments July November 2021. They grouped into 27 morphotypes, including fi...

Leaf composts were studied for their suppressive effects on Pythium ultimum sporangium germination, cottonseed colonization, and the severity of Pythium damping-off of cotton. A focus of the work was to assess the role of fatty-acid-metabolizing microbial communities in disease suppression. Suppressiveness was expressed within the first few hours of seed germination as revealed by reduced P. ul...

The capacity of Azospirillum brasilense to enhance the accumulation of K, P, Ca, Mg, S, Na, Mn, Fe, B, Cu, and Zn in inoculated wheat and soybean plants was evaluated by using two different analytical methods with five A. brasilense strains originating from four distinct geographical regions. A Pseudomonas isolate from the rhizosphere of Zea mays seedlings was included as a control. All A. bras...

Oropharyngeal candidiasis is an opportunistic infection considered to be a harbinger of AIDS. The etiologic agent Candida albicans is a fungal species commonly colonizing human mucosal surfaces. However, under conditions of immune dysfunction, colonizing C. albicans can become an opportunistic pathogen causing superficial or even life-threatening infections. The reasons behind this transition, ...

Zooplankton consumption of aggregates, such as marine snow, is an important factor in determining the efficiency biological carbon pump. However, feeding rates aggregate-associated small harpacticoid and poecilostomatoid copepods are largely unknown, factors that influence these rates. We measured functional responses pellet production (PP) aggregate-feeding on appendicularian houses, algal det...

Although gastrointestinal colonization by the opportunistic fungal pathogen Candida albicans is generally benign, severe systemic infections are thought to arise due to escape of commensal C. albicans from the gastrointestinal (GI) tract. The C. albicans transcription factor Efg1p is a major regulator of GI colonization, hyphal morphogenesis, and virulence. The goals of this study were to ident...
