“…Our results strongly support previous studies reporting an association between C. pneumoniae infection markers and elevated BMI. [5][6][7][8]10,12 However, several other studies did not find such association. [27][28][29][30][31][32] Our study included over 5000 individuals, which is to the best of our knowledge, the largest study of the topic.…”

“…The seroprevalence of C. pneumoniae is higher among men than women, 10,13 thus implying that men may be more susceptible for this pathogen and/or that their antibody response against it is more efficient. Possibly, women have less efficient clearance of C. pneumoniae infections, which may predispose them for persistent infections and for dissemination of the pathogen from lungs to other tissues.…”

“…Also some bacteria, especially Helicobacter pylori and Chlamydia pneumoniae, have been reported to associate with elevated body mass index (BMI), overweight, obesity or metabolic syndrome in humans, both alone and in combination with other microbes. [5][6][7][8][9][10][11][12] However, the causality between infections and these conditions is not currently known.…”

“…19,20 Slightly elevated levels of serum C-reactive protein (CRP) are considered as a marker of systemic low-grade inflammation associated with obesity, insulin resistance and metabolic syndrome, 21 and future cardiovascular events. [21][22][23][24][25][26] Previous studies concerning the association between C. pneumoniae infection markers and overweight/obesity have focused only on BMI and/or have had rather small sample size, [5][6][7][8]10,12,[27][28][29][30][31][32] the results being contradictory. In our large (n ¼ 5044), well-defined population, our aim was to study whether C. pneumoniae-specific IgG antibodies are associated with elevated BMI, and whether the risk is more pronounced in those individuals with an ongoing inflammation, measured by elevated high-sensitive CRP (hsCRP) levels.…”

“…The risk of zoonotic transmission is presumably greater for immunocompromised individuals. C. felis infection has been associated with conjunctivitis and/or respiratory tract disease (4,15), community-acquired pneumonia (21), hepatosplenomegaly, glomerulonephritis, and endocarditis in humans (31).…”

Multilocus Variable-Number Tandem-Repeat Analysis Scheme for Chlamydia felis Genotyping: Comparison with Multilocus Sequence Typing

Chlamydia felis is an important ocular pathogen in cats worldwide. A multilocus variable-number tandem-repeat analysis (MLVA) system for the detection of tandem repeats across the whole genome of C. felis strain Fe/C-56 was developed. Nine selected genetic loci were tested by MLVA in 17 C. felis isolates, including the C. felis Baker vaccine strain, and 122 clinical samples from different geographic origins. Analysis of the results identified 25 distinct C. felis MLVA patterns. In parallel, a recently described multilocus sequence typing scheme for the typing of Chlamydia was applied to 13 clinical samples with 12 different C. felis MLVA patterns. Rare sequence differences were observed. Thus, the newly developed MLVA system provides a highly sensitive high-resolution test for the differentiation of C. felis isolates from different origins that is suitable for molecular epidemiological studies.

Following a large outbreak of community-acquired psittacosis in 2002 in residents of the Blue Mountains, New South Wales, Australia, we reviewed new cases in this area over a 7-year period from 2003 to 2009. Using the 2010 criteria from the Centers for Disease Control National Notifiable Diseases Surveillance System, 85 patients with possible psittacosis were identified, of which 48 were identified as definite or probable infection. Clinical features of these cases are summarized. In addition to Chlamydia -specific serology, specimens, where available, underwent nucleic acid testing for chlamydial DNA using real-time PCR. Chlamydophila psittaci DNA was detected in samples from 23 patients. Four of 18 specimens were culture positive. This is the first description of endemic psittacosis, and is characterized in this location by community-acquired psittacosis resulting from inadvertent exposure to birds. The disease is likely to be under-diagnosed, and may often be mistaken for gastroenteritis or meningitis given the frequency of non-respiratory symptoms, particularly without a history of contact with birds. Clinical characteristics of endemic and outbreak-associated cases were similar. The nature of exposure, risk factors and reasons for the occurrence of outbreaks of psittacosis require further investigation.
