Molecular detection of Chlamydia psittaci in wild birds, broiler chickens, and sheep in Egypt: a public health concern.
Article in BMC veterinary research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundChlamydia psittaci is a neglected pathogen of global concern, characterized by significant zoonotic and spillover potential, posing considerable risks to public health. This study aimed to investigate the prevalence of C. psittaci in broiler chickens, wild resident birds, and sheep in Egypt using molecular detection and sequence analysis to explore possible zoonotic relevance.
methodsA total of 230 oropharyngeal swabs were collected from apparently healthy animals, including broiler chickens (n = 100), resident wild birds (n = 80; hooded crows n = 20, cattle egrets n = 20, rock pigeons n = 20, and laughing doves n = 20), and sheep (n = 50). Genomic DNA was extracted and screened using PCR targeting the Chlamydia genus-specific 16S rRNA gene. Species identification of C. psittaci was confirmed by amplification of the ompA gene. Moreover, sequencing and phylogenetic analysis of the ompA gene were performed.
resultsThe overall prevalence of C. psittaci was 3.5% (8/230). Positive samples were identified in broiler chickens (5/100; 5%), hooded crows (1/20; 5%), rock pigeons (1/20; 5%), and sheep (1/50; 2%), while cattle egrets and laughing doves tested negative. Phylogenetic analysis of the ompA gene sequence showed close clustering with previously reported C. psittaci strains from seabirds, confirming a strong genetic relationship.
conclusionThe detection of C. psittaci in broiler chicken, wild birds, and sheep within the same geographic area highlights the potential circulation of this pathogen among multiple host species. These findings emphasize the importance of developing targeted surveillance systems and implementing One Health control strategies.
