Neopterin as a Tool for Primate Ecoimmunology: Current Knowledge, Practical Application, and New Directions From Captivity to the Wild

American Journal of Primatology, Volume 87, Issue 10, October 2025.
Neopterin is a sensitive and specific biomarker of intracellular pathogen infection and chronic inflammation, and affected by environmental, life‐history, and sex‐contextual factors. This review offers best‐practice guidelines and practical advice on sample collection, storage, and analysis in primates when used for ecoimmunological conservation and ...

Construction and Characterization of Novel Shuttle Expression Vectors for Actinobacillus succinogenes

Biotechnology and Applied Biochemistry, Volume 72, Issue 5, Page 1265-1273, October 2025.
ABSTRACT Actinobacillus succinogenes is a ruminal microorganism of biotechnological importance due to its capacity to produce succinic acid at high yields. Despite the scientific interest in this organism, molecular vehicles for the transfer and expression of genetic material are limited compared to the existing demand.

Production of a capsule of Neisseria gonorrhoeae [PDF]

Infection and Immunity, 1977
Neisseria gonorrhoeae can be induced to form a large capsule that can be visualized with India ink. Encapsulated gonococci appeared to be resistant to non-antibody-mediated phagocytosis compared with unencapsulated gonococci of the same strain and colony type.
