Wolbachia is a widespread and well-known bacterium that can induce a wide range of changes within its host. Ants specifically harbor a great deal of Wolbachia diversity and are useful systems to study endosymbiosis. The turtle ants (Cephalotes) are a widespread group of tropical ants that rely on gut microbes to support their herbivorous diet for their survival, yet little is known of the extent of this diversity. Therefore, studying their endosymbionts and categorizing the diversity of bacteria within Cephalotes hosts could help to delimit species and identify new strains and can help lead to a further understanding of how …

A new, simplified protocol for determining particulate adenosine triphosphate (ATP) levels allows for the assessment of microbial biomass distribution in aquatic systems at a high temporal and spatial resolution. A comparison of ATP data with related variables, such as particulate carbon, nitrogen, chlorophyll, and turbidity in pelagic samples, yielded significant and strong correlations in a gradient from the tributaries of the Chesapeake Bay (sigma-t = 8) to the open North Atlantic (sigma-t = 29). Correlations varied between ATP and biomass depending on the microscopic method employed. Despite the much greater effort involved, biomass determined by microscopy correlated poorly with other …

Viral metabolic reprograming of marine prokaryotes, through the use of virally encoded auxiliary metabolic genes (AMGs), plays a critical role in marine ecosystem function by influencing biochemical cycles and genetic diversity in these environments. Despite the fundamental role viruses play in global environmental ecosystems, they remain an understudied aspect of microbial ecology and evolution, in part due to the methods available for studying virus host interactions in natural systems. Thus far, metagenomic analyses have been used to study the interactions of virus host pairs, but these types of analyses have their limitations in accurately linking viruses to hosts, or culture-based …

Bacteriophages are viruses that infect a wide variety of host bacteria with some strains having medical and industrial significance. These highly abundant and genetically bacterial viruses constitute a large amount of unexplored genetic information. Because bacteriophages are highly specific, they can be used therapeutically to combat bacterial infections by selecting a phage to target and kill harmful bacteria. Thus, phage therapy is currently being explored to aid in the fight against antibiotic resistance. Actinobacteriophages are viruses that specifically infect Phylum Actinobacteria hosts including the environmentally abundant Gordonia terrae. Some species of Gordonia, including G. terrae, have also …

The northern coastal zones of Puerto Rico, including the San Juan Bay and Rio Grande de Loiza watersheds, are increasingly becoming focal points of environmental concern due to wastewater originating from human activity. This runoff, which consists of effluents from sewage treatment, septic tanks, and animal husbandry, enters coastal lagoons and estuaries, posing critical threats to these vital ecosystems. This study aims to determine the presence of Leptospira in over 100 samples from 16 sub-basins over 2 years as well as identify the major sources of fecal pollution using molecular source tracking techniques. End point PCR assays for Leptospira (LipL32), …
