The koala biovar of Chlamydia pneumoniae was identified in lung tissue from a sick, free-ranging giant barred frog (Mixophyes iteratus) by using electron microscopy, C. pneumoniae-specific fluorescent-antibody staining, cell culture, and sequencing of the ompA, ompB and 16S rRNA genes. This is the first report of a chlamydial strain infecting both a homeotherm and a poikilotherm and only the fo...

There are two main human pathogens in the family of Chlamydiaceae. Different serovars of Chlamydia ii TABLE OF CONTENTS

Streptococcus pneumoniae is the most common cause of CAP, at a rate of 9.6% to 48.8% of cases with an etiologic diagnosis. Mycoplasma pneumoniae is one of the primary causes of pneumonia in young patients, mainly those under 20 years old. Chlamydia pneumoniae can affect young patients and adults with underlying diseases, causing 5%-15% of CAP episodes. Chlamydia psittaci and Coxiella burnetii a...

Elicited macrophages from 129sv mice with a functional deletion of the natural-resistance-associated macrophage protein 1 gene (Nramp1) were shown to be as susceptible as wild-type mice to infection with the Chlamydia trachomatis mouse pneumonitis and L3 serovars and to Chlamydia pneumoniae. Furthermore, the two groups of mice were shown to be similarly susceptible to an intranasal infection wi...

Mycoplasma pneumoniae and Chlamydia spp., which are associated with community-acquired pneumonia (CAP), are difficult to propagate, and can cause clinically indistinguishable disease patterns. During 2011-2012, we used molecular methods to test adult patients in Germany with confirmed CAP for infection with these 2 pathogens. Overall, 12.3% (96/783) of samples were positive for M. pneumoniae an...

Chlamydia trachomatis and Chlamydophila pneumoniae are human pathogens; the former being the etiologic agent for trachoma as well as a prevalent sexually transmitted bacterium, while C. pneumoniae is a respiratory pathogen responsible for community-acquired pneumonia. Patients with reactive arthritis show evidence of present or past Chlamydial infection. Chlamydia spp., has been strongly implic...

Chlamydia trachomatis is currently, the major cause of bacterial sexually transmitted infections (STIs) worldwide. Infection prevalence peaks in women younger than 25 years. There is increasingly more evidence that infection with Chlamydia trachomatis can cause adverse pregnancy and infant health outcomes (stillbirth, premature rupture of membranes, puerperal infections, miscarriage, ectopic pr...
