Prevalence of the bla CTX-M-1 group and their transferability in resistant clinical isolates of Salmonella serogroups from several hospitals of Tehran.
Article in Iranian journal of microbiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
BACKGROUND AND
objectivesSalmonella is an important food-borne pathogen in humans. Strains of Salmonella spp. that producing extended-spectrum β-Lactamases have become a concern in medicine regarding both antimicrobial treatment and infection control program. The objective of this study was to describe the antibiotic susceptibility, ESBL production and determining the prevalence of the bla CTX-M-1 group among clinical isolates of Salmonella spp. MATERIALS AND
methodsA total of 110 Salmonella isolates collected from four Tehran hospitals during May 2012 and April 2013. The specific monovalan Salmonella antisera were used for serogrouping of Salmonella isolates. Antibacterial susceptibility was determined by disk diffusion and ESBL phenotype was confirmed by combination disk method. The bla CTX-M-1 group was identified by PCR with specific primers. The transferability of the bla CTX-1 group was tested by conjugation with broth matting method.
resultsThe prevalence of Salmonella serogroups consist of 56.4% serogroup D, 13.6 % serogroup C, 10 % serogroup B, and 1.8 % serogroup A and 18.2% other serogroups. Maximal resistance in Salmonella isolates was noticed against trimethoprim-sulfamethoxazole (63.6%) and nalidixic-acid (47/3%). All isolates were susceptible to imipenem and ciprofloxacin. Four isolates (3.6%) showed ESBLs phenotype. All Salmonella spp. that produce ESBls have bla CTX-1 genes group. A conjugative plasmid containing bla CTX-1 group was found in one Salmonella isolate.
conclusionThis study demonstrates the predominant presence of the gene encoding CTX-M-1 group among ESBLs producing of Salmonella spp. They can transmit to bacteria of this genus or even other genera of enteric bacteria.
