“…it is bedeviled by a high level of operator error, 24 and by cross-reactions with other chlamydophilae 25 and mycoplasma species. 26,27 In addition, some investigators support that the detection of C. pneumoniae antibodies may be a poor guide to the presence of infection.…”

Conflicting data exist regarding the relationship between Chlamydophila pneunoniae (C. pneumoniae) and hypertension. In this study, both C. pneumoniae IgG and IgA titres and Epstein-Barr virus antibody levels were measured in 146 sustained hypertensives defined by 24 h ambulatory blood pressure monitoring (ABPM) and 54 normotensives. C. pneumoniae antibodies were measured by microimmunofluorescence test. IgGX80 and IgAX40 were defined as elevated antibody titres. Epstein-Barr antibodies were measured in order to investigate whether a possible association exists between hypertension and other, similarly widespread in the general population, intracellular microorganisms. All participants underwent casual blood pressure (BP) readings and 24 h ABPM. Subjects having mean 24 h systolic/diastolic ambulatory BP4125/80 mmHg, with or without antihypertensive medication were defined as hypertensives. Controls were free of any history or clinical evidence of hypertension, cardiovascular or pulmonary disease. Of the total participants, 77 hypertensives (52.7%) and 10 normotensives (18.5%) had IgA titres X40 (crosstabs Po0.000), whereas 76 hypertensives (52.1%) and 15 normotensives (27.8%) had IgG titres X80, (crosstabs Po0.002). No difference was found in Epstein-Barr antibodies, between hypertensives and normotensives. In conclusion, C. pneumoniae, but not Epstein-Barr, antibody levels were found significantly higher in sustained hypertensives, suggesting high frequency of chronic C. pneumoniae, infections in this specific group of patients.

“…The role of wild pigeons and pheasants as source of Chlamydophila psittaci to humans and animals has been reported by Travnicek et al [13]. Chlamydophila psittaci may be transmitted from person to person in a hospital setting [17]. Domiciliary outbreak of chlmydiosis in dogs with potential zoonotic transmission is documented by Greshan et al [18].…”

Emerging zoonoses of varied etiologies constitute an important cause of morbidity and mortality in humans and in a wide species of animals. Among these, chlamydiosis caused by Chlamydiophila psittaci, is an infectious emerging zoonosis of considerable significance. The disease is reported from many countries of the world including India. The respiratory tract is recognized as the prime portal of entry. Clinical findings are variable, which include respiratory, gastrointestinal, neurological, musculoskeletal and dermatological. Mortality rate in untreated patients can be 10 to 20%. Chlamydiosis can be diagnosed by microbiological, immunological and molecular techniques. Tetracyclines and doxcycycline are considered the treatment of choice. It is imperative that patient with atypical pneumonia and history of contact with birds should be investigated for C. psittaci infection. Increased awareness about disease can help to shorten the diagnostic delay and improve patient outcome. It is emphasized that zoonotic transmission risk from pet birds and domestic animals should be further recognized. New approaches for the control of chalmydiosis in poor resource nations seem imperative. Stronger cordial cooperation is required among the veterinary, medical, public health and wild life scientists to control the emerging zoonoses including chlamydiosis. Keywords:

“…Even a short exposure to birds or bird wastes, as well as seemingly unrelated activities like gardening or lawn-mowing without a grass catcher, can result in infection (Telfer et al, 2005;Williams et al, 1998). Person-to-person transmission is possible but is considered rare (Hughes et al, 1997;Ito et al, 2002;Williams et al, 1998). C. psittaci should be handled carefully under conditions of biocontainment.…”
