A molecular survey of Chlamydia spp. infection in commercial poultry and detection of Chlamydia pneumoniae in a commercial turkey flock in Iran.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundChlamydiaceae are a group of gram-negative intracellular bacteria which can infect a wide variety of hosts. Some chlamydial agents are capable of crossing the host barrier and though they are potentially a risk to very different species. They also pose a zoonotic risk for human and different chlamydial agents are linked to several medical maladies.
objectivesIn this study, the presence of chlamydial agents in different commercial poultry flocks in Iran was investigated.
methodsSwab and tissue samples were collected from 435 birds in 24 different commercial poultry flocks. These samples were examined using a Chlamydiaceae-specific real-time PCR assay targeting 23S rRNA gene. Positive samples then were subjected to intergenic spacer rRNA (IGS) gene and major outer membrane protein gene (ompA) PCRs. Finally, positive PCR products were sequenced and analysed.
resultsOnly one flock of commercial turkey became positive. Partial DNA sequencing of IGS gene revealed that all positive samples from the infected flock were Chlamydia pneumoniae and were identical to previously studied isolates from koala (LPCoLN) and frog (DC9). Further investigations showed slight dissimilarity in ompA gene of C. pneumoniae from different hosts. The detected turkey isolates were located in a different clade of phylogenetic tree, close to Western barred bandicoot and koala isolates.
conclusionC. pneumoniae has passed the cross-species barrier in the past and therefor it could potentially be zoonotic. To the best of authors' knowledge, this is the first report of C. pneumoniae infection in commercial turkey.
