Gram positive bacilli in the urine are usually dismissed as contaminants in urine specimens as these are commensal flora of skin and mucous membranes. Corynebacterium species were misidentified in the past due to complex biochemicals but the advent of modern diagnostics has made their identification quicker and accurate. Corynebacterium species have recently emerged as pathogens of nosocomial outbreak potential. C. striatum has been identified as opportunistic nosocomial pathogen causing various infections. We report first case of C. striatum as nosocomial urinary tract infection (UTI) pathogen in a child with bilateral renal disease. C. striatum causing UTI is very rarely reported.

While bioprocesses using Escherichia coli, Corynebacterium glutamicum, various species of Bacillus, lactic acid bacteria, Clostridia, the yeasts Saccharomyces cerevisiae and Pichia pastoris, fungi such as Aspergillus niger, and Chinese hamster ovary cells are well established, the high level of microbial diversity has not yet been exploited industrially. However, the use of alternative organisms has the potential to significantly expand the process window of bioprocesses. These extensions include the use of alternative substrates (e.

The ocular surface microbiome (OSM) is a low-density, low-diversity microbial ecosystem influenced by host and environmental factors, including age, hygiene, contact lens use, and systemic disease. Unlike other mucosal sites, the eye lacks a well-defined core microbiome, and its microbial composition varies significantly between individuals. Advances in metagenomics have revealed that commensals such as and may contribute to immune regulation and homeostasis.

Cattle are a reservoir for the zoonotic human foodborne pathogen Shiga toxin-producing Escherichia coli (STEC), the causative agent of many disease outbreaks associated with contaminated fresh leafy greens. Concentrated animal feeding operations (CAFOs) housing cattle generate fugitive dust, however the potential risk of STEC movement by means of the aerosolized dust is not well known. In this investigation, we used metagenome sequencing of air samples collected in an agricultural setting to investigate airborne transfer of STEC from a large CAFO to the surrounding area.

Background: Breast milk represents the optimal feeding strategy for newborns, supporting not only nutrition but also the establishment of a unique microbiota. The bacterial composition and diversity of this microbiota are shaped by various maternal and infant-related factors.
Objectives: This single-center prospective study aimed to examine the breast milk microbiota and determine the maternal and infant-related factors influencing its composition and diversity over the time.

Background: Early-onset neonatal sepsis (EOS) is a critical condition primarily caused by maternal-fetal transmission of bacterial pathogens during delivery, with Escherichia coli and Group B Streptococcus being the most prevalent. However, neonatal sepsis can also involve other rare bacteria, including Corynebacterium amycolatum, which was first described in 1988 and is widely recognized as an emerging pathogen in infectious diseases.
Case Presentation: A male infant was admitted to the neonatal intensive care unit (NICU) due to premature birth and tachypnea.
