Experimental Chlamydia gallinacea infection in chickens does not protect against a subsequent experimental Chlamydia psittaci infection [PDF]

, 2021
Chlamydia psittaci was considered the predominant chlamydial species in poultry until Chlamydia gallinacea was discovered in 2009. C. psittaci is a zoonotic obligate intracellular bacterium reported in more than 465 bird species including poultry.

A Family Outbreak of Chlamydia psittaci Infection

Journal of the Japanese Association for Infectious Diseases, 1996
A family outbreak (3 cases) of Chlamydia psittaci infection was reported. The first case, a 56-year-old man was admitted with fever and general fatigue. Chest X-ray film revealed a consolidation in the right lower lung. One month before admission he had purchased 2 parakeets (chick) and one parakeet died.

Comparative Analysis of Chlamydia psittaci Genomes Reveals the Recent Emergence of a Pathogenic Lineage with a Broad Host Range

mBio, 2013
Chlamydia psittaci is an obligate intracellular bacterium. Interest in Chlamydia stems from its high degree of virulence as an intestinal and pulmonary pathogen across a broad range of animals, including humans. C.

Studies of human immune responses to various antigenic proteins of Chlamydia trachomatis [PDF]

Chlamydiae are gram-negative bacteria which cause diverse diseases of humans and animals. Chlamydia trachomatis, the focus of this work, causes the blinding eye disease trachoma, and reproductive tract infections.

Extranodal Marginal Zone Lymphoma: Integrating Etiology, Microenvironment, and Genetics Into Clinical Decision‐Making

European Journal of Haematology, Volume 117, Issue 4, Page 849-863, October 2026.
ABSTRACT Extranodal marginal zone lymphoma (EMZL) represents a unique paradigm among indolent B‐cell neoplasms, in which lymphomagenesis is frequently driven by chronic antigenic stimulation within tissue‐specific microenvironments. Persistent infectious or autoimmune triggers promote the development of ectopic lymphoid tissue and sustain B‐cell ...

A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

Advanced Science, Volume 13, Issue 26, 8 May 2026.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...
