Occurrence of Shiga toxin-producing Escherichia coli carrying antimicrobial resistance genes in sheep on smallholdings in Bangladesh.
Article in Veterinary medicine and science, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundShiga toxin-producing Escherichia coli (STEC) are zoonotic foodborne pathogens and a significant concern with the emergence of antibiotic resistance. Close human contact might have a higher chance of being transmitted to humans from sheep if the sheep population is a potential reservoir of antimicrobial-resistant STEC. Therefore, this study aimed to examine the sheep population in rural Bangladesh for antimicrobial-resistant STEC.
methodsWe screened 200 faecal samples collected from sheep in three Upazilas from the Chattogram district. Randomisation of sampling was not performed due to the smaller flock size (two to six animals per smallholding). Phenotypically positive E. coli isolates were examined for two Shiga toxin-producing genes - stx1 and stx2. PCR-positive STEC isolates were investigated for the presence of antimicrobial resistance (AMR) genes - bla
resultsIn total, 123 of the 200 tested samples were confirmed positive E. coli using culture-based methods. PCR results show 17 (13.8%) E. coli isolates harboured ≥ one virulent gene (stx1 or/and stx2) of STEC. The AMR profile of STEC isolates was determined utilising the disc diffusion method. Of the STEC isolates, 82, 76, 71 and 71% were susceptible to chloramphenicol, gentamicin, ciprofloxacin and ampicillin. In contrast, 47% of isolates were resistant to trimethoprim-sulfamethoxazole, and 41% were resistant to amoxicillin. In addition, six of the tested STEC isolates exhibited the bla
conclusionTo our knowledge, this study is the first to reveal a substantial percentage of STEC isolated from sheep in rural Bangladesh harbouring AMR genes.
