A high speed flow cytometric cell sorter was modified to maintain a controlled anaerobic environment. This technology enabled coupling of the precise high-throughput analytical and cell separation capabilities of flow cytometry to the assessment of cell viability of evolved lineages of obligate anaerobic organisms from cocultures.

Background: The rumen fluke, Calicophoron daubneyi, is the major paramphistome species infecting ruminants within Europe. Adult flukes reside within the rumen where they are in direct contact with a unique collection of microorganisms. Here, we report a 1.

Background/objectives: Several independent studies have associated prostate cancer (PCa) with specific groups of bacteria, most of them reporting the presence of anaerobic or microaerophilic species such as (). Such findings suggest a prostate cancer-related bacterial dysbiosis, in a manner similar to the association between infection and gastric cancer. In an earlier exploratory study looking for such dysbiosis events, using a culturomics approach, we discovered that the presence of obligate anaerobes (OAs) along with was associated with increased prostate-specific antigen (PSA) levels in 39 participants.

() is a Gram-negative, obligate anaerobic, commensal bacterium residing in the human gut and holds therapeutic potential for ulcerative colitis (UC). Previous studies have indicated that capsular polysaccharide A (PSA) of is a crucial component for its effectiveness, possessing various biological activities such as anti-inflammatory, anti-tumor, and immune-modulating effects. We previously isolated and characterized the strain ZY-312 from the feces of a healthy breastfed infant, and extracted its PSA, named TP2.

A Gram-positive, rod-shaped, and obligate anaerobic bacterial strain OS1-26 was isolated from apple orchard soil in Iksan, South Korea. Interestingly, strain OS1-26 was observed to possess the functional genes involved in biological nitrogen fixation (BNF), including , which was actively transcribed during the anaerobic cultivation with excessive production of extracellular NH despite of presence of other fixed N nutrients. The BNF of strain OS1-26 was distinguished from the other well-known diazotrophs, such as and .

Dietary profiles of wild carnivores and Blastocystis occurrence: The case of the endangered Iberian lynx (Lynx pardinus) and systematic review.

Recent molecular and metagenomic studies have revealed that the obligate anaerobic protist Blastocystis is found more prevalently and with higher subtype diversities in herbivore species than in carnivore species. However, information on wild carnivore species is scarce. Here, we investigated the presence of Blastocystis by molecular methods in fecal DNA samples of free-ranging and captive Iberian lynxes from Spain (n = 243) and Portugal (n = 30).
