1 · What the graph read from it

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.

2 · The registry

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

backgroundTick-borne pathogens are increasingly recognized as important threats to veterinary and public health. However, the epidemiological role of cats in the transmission of Anaplasma phagocytophilum-related strains and Hepatozoon spp. remains unclear. In Türkiye, A. phagocytophilum-like 1 (AP-like 1) has been reported in ruminants and ticks; however, molecular evidence in feline hosts has not been documented. This study aimed to investigate the molecular prevalence and genetic diversity of A. phagocytophilum-related strains and Hepatozoon spp. in domestic cats from eastern Turkey.

methodsBlood samples from 93 domestic cats from animal shelters in Van and Batman provinces were screened using PCR targeting the 16S rRNA gene of Anaplasma spp. and the 18S rRNA gene of Hepatozoon spp. Positive samples were characterized by restriction fragment length polymorphism and sequencing, followed by phylogenetic analysis using the Maximum Likelihood method.

resultsAnaplasma DNA was detected in 78.5% (73/93) of cats, and RFLP analysis indicated that all positive samples were consistent with AP-like 1, representing the first molecular evidence of this variant in domestic cats in Türkiye. Phylogenetic analyses revealed that the feline isolates clustered with ruminant-derived strains, suggesting shared transmission cycles and low host specificity. Hepatozoon spp. DNA was detected in 8.6% (8/93) of the samples. Based on sequencing and phylogenetic analyses of a subset of positive samples, the isolates were identified as Hepatozoon felis genotype I. The absence of other variants in the sequenced subset may suggest regional differences; however, this finding should be interpreted cautiously due to the limited number of sequences analyzed.

conclusionThese findings demonstrate a high prevalence of AP-like 1 and support the circulation of Hepatozoon felis genotype I in domestic cats from eastern Türkiye, highlighting the potential role of feline hosts in regional transmission dynamics. This study expands current knowledge of the host range and epidemiology of A. phagocytophilum-related strains and Hepatozoon spp. and underscores the importance of integrated molecular surveillance and vector control strategies within the One Health framework.
