During a study on Trypanosoma equiperdum propagation in adult male Wistar rats, four rats died spontaneously. Two of the dead animals were subjected to post mortem examination. From different organs of the rats, chlamydiae were isolated and confirmed by PCR and DNA sequencing as Chlamydophila psittaci. The results show that infection with Chlamydophila psittaci may occur in laboratory rats. Suc...

Bacteria belonging to the family Chlamydiaceae cause a broad spectrum of diseases in a wide range of hosts, including humans, other mammals and birds. However, very little is known about chlamydial infections in birds in our region. In the present study, we examined 28 clinically normal birds in illegal captivity that were confiscated in the province of C6rdoba, Argentina. The objective was to ...

BACKGROUND AND OBJECTIVE Chlamydophila psittaci is a lethal bacterium that causes endemic avian chlamydiosis, and respiratory psittacosis. Laboratory diagnosis of Chlamydophila psittaci is difficult by culture. This study was design to investigate the presence of Chlamydophila psittaci in collected pharyngeal swabs from asyptomatic pigeons by PCR. MATERIALS AND METHODS Pharyngeal samples from...

The aim of the study was to investigate the prevalence of Chlamydophila felis infection in cats from Wroclaw city. Fiftytwo cats with ocular signs of chronic conjunctivitis, selected on the basis of anamnesis, ophthalmological examination, and clinical symptoms, were included in the screening study. Using cotton swabs, conjunctival samples were collected from all animals. The samples were analy...

Consolidation and Ground-Glass Opacities (GGO) are common findings on chest Computed Tomographic (CT) scans. Consolidation and GGO can be divided into segmental, non-segmental and interstitial pneumonia types based upon distribution pattern. The aim of this review is to highlight the importance of the non-segmental distribution pattern, and to explain its relevancy in various conditions. Non-se...

The aims of this work was documentation of the reactivity of feline conjunctival epithelial cells in chronic conjunctivitis and the investigation of a possible correlation of histological findings in conjunctiva with a limitation in detection of the pathogen. In this observational study, conjunctival swab samples collected from six cats suffering from chronic conjunctivitis were monitored for C...

Summary of a study, which may be published alone or as an introduction to a full scientific paper. A-DROP score Severity scoring system developed by the Japanese respiratory society that includes the following parameters: Age (male ≥ 70 years, female ≥ 75 years) Dehydration (blood urea nitrogen (BUN) ≥ 210 mg/l) Respiratory failure (SaO2 ≤ 90% or PaO2 ≤ 60 mm Hg) Orientation disturbance (confus...

BACKGROUND Chlamydophila pneumoniae and Mycoplasma pneumoniae are associated with acute exacerbation of bronchial asthma (AEBA). The aim of this study was to evaluate the correlation between these acute bacterial infections and the severity of AEBA. METHODS We prospectively analysed consecutive patients admitted to the Emergency Department with acute asthma exacerbation. In every patient peak...

Free-living amoebae feed on bacteria, fungi, and algae. However, some microorganisms have evolved to become resistant to these protists. These amoeba-resistant microorganisms include established pathogens, such as Cryptococcus neoformans, Legionella spp., Chlamydophila pneumoniae, Mycobacterium avium, Listeria monocytogenes, Pseudomonas aeruginosa, and Francisella tularensis, and emerging patho...

The phylogenetic relationships among Chlamydia spp. were investigated by comparing 16S rRNA gene sequences. In this analysis we used 14 strains of Chlamydia psittaci, including seven feline isolates, two avian isolates, two human isolates, one bovine isolates, one ovine isolate, and one koala isolate; and nine strains of Chlamydia trachomatis, including six human isolates, two swine isolates, a...
