Challenges in Chlamydial Serology: Insights from a Belgian and a Dutch Population Cohort.

Serology routinely serves as a diagnostic tool to confirm infections in humans. Particularly in delayed settings, such as post-outbreak scenarios where the acute phase of infection has subsided, serology is invaluable. Multiple studies, nonetheless, indicate deficiencies in specificity and sensitivity of current chlamydial antibody detection assays.

Chlamydia psittaci infected cell studies by 4Pi Raman and atomic force microscopy.

Chlamydia psittaci is an avian bacterial pathogen that can cause atypical pneumonia in humans via zoonotic transmission. It is a Gram-negative intracellular bacterium that proliferates inside membrane bound inclusions in the cytoplasm of living eukaryotic cells. The study of such cells with C.

, and are the most common spp. in chickens and have a confirmed or suggested zoonotic potential. No recent data are available on their prevalence and impact in the Belgian chicken industry or in the recreational chicken branch.

Three Cases of Atypical Pneumonia with : The Role of Laboratory Vigilance in the Diagnosis of Psittacosis.

is an established zoonotic agent causing respiratory disease in humans. An infection often remains asymptomatic but can also result in flu-like illness, pneumonia or even multi-organ failure. This paper describes three patients, hospitalised at AZ Sint-Lucas Hospital, with atypical pneumonia who were diagnosed with after an in-depth anamnesis and laboratory investigation in the midst of the COVID pandemic.
