Parachlamydia acanthamoebae and Its Zoonotic Risk


Borel, N; Pospischil, A; Greub, G (2010). Parachlamydia acanthamoebae and Its Zoonotic Risk. Clinical Microbiology Newsletter, 32(24):185-191.

Abstract

Parachlamydia acanthamoebae has been implicated as an emerging agent of pneumonia in humans. Recently, it has been linked to miscarriage and neonatal infections. In contrast, its role in atherosclerosis remains controversial. In animals, there is strong evidence for Parachlamydia as a new abortigenic in cattle, and further data on this agent in other animal species is accumulating. New diagnostic methods, such as specific real-time PCR and immunohistochemistry with specific anti-Parachlamydia antibodies to detect the organism within lesions, are now available to facilitate the diagnosis of parachlamydial infections in humans and animals. This review discusses parachlamydial infections in clinical settings in humans and animals, as well as their zoonotic potential and possible modes of transmission. Current diagnostic tools are presented, and finally, the antibiotic susceptibility of Parachlamydia is described for potential future preventive and therapeutic options. Nevertheless, more data on Parachlamydia and Chlamydia-like organisms are needed to elucidate their host range and pathogenic potential in humans and animals.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
