Lyme Disease Risk of Exposure to Blacklegged Ticks (Acari: Ixodidae) Infected with Borrelia burgdorferi (Spirochaetales: Spirochaetaceae) in Pittsburgh Regional Parks

open access: yesJournal of Medical Entomology, 2019
AbstractLyme disease is the most commonly reported vector-borne illness and sixth most commonly reported notifiable infectious disease in the United States. The majority of cases occur in the Northeast and upper-Midwest, and the number and geographic distribution of cases is steadily increasing.

Bacterial diversity in the clarki ecotype of the photosynthetic sacoglossan, Elysia crispata

open access: yesMicrobiologyOpen, Volume 9, Issue 9, September 2020., 2020
The bacterial diversity of the solar‐powered sea slug, Elysia crispata (clarki ecotype), was investigated. The results showed inter‐individual variability in bacterial diversity, suggesting that the bacteria live commensally with these sea slugs. Abstract Few studies have examined the bacterial communities associated with photosynthetic sacoglossan sea

Spirochetes: Borrelia and Brachyspira [PDF]

open access: yes, 2016
Spirochete infections of birds are caused by helical-shaped bacteria of the order Spirochaetales, family Spirochaetaceae. Two distinct syndromes exist because of differences in spirochete colonization, pathogenesis, and lesion production; non-relapsing ...

Drivers of Microbiome Composition Among Helminth Parasites Sharing the Same Insectivorous Bat Host

open access: yesMolecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Parasitic metazoans are increasingly recognised to form close associations with microbial taxa. Under the holobiont concept, these associations are an eco‐evolutionary unit under joint selection. However, for most parasitic helminth species and particularly those associated with wildlife, these interactions and their effect on parasite ...

Exploring the Potential of Microalgae Cocultivation on Bacterial Community Dynamics in a Nile Tilapia and Garlic Aquaponic System

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
The cocultivation of microalgae in aquaponic systems can improve nutrient removal and enhance water quality. Moreover, it can promote the biological and physicochemical balance in aquaponic ecosystems. However, the bacterial communities in aquaponic systems have not yet been comprehensively characterized and the effects of microalgae cocultivation ...

Associations Between Oral Microbiota Pathogens and Elevated Depressive and Anxiety Symptoms in Men

open access: yesDepression and Anxiety, Volume 2025, Issue 1, 2025.
Systemic inflammation is associated with depression. Certain oral bacterial species contribute to inflammation; however their potential association with mental disorders remains unclear. This study investigated the associations between oral microbiota pathogens and depressive and anxiety symptoms.
