TLR2 c.374C>T variant linked to natural resistance against brucellosis in Italian Mediterranean river buffalo.
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundBrucellosis poses a significant threat to human health and the livestock industry, particularly affecting small-scale farmers. Several studies have demonstrated that TLR2 can recognize the Brucella abortus (B. abortus) surface lipoproteins (i.e. Omp10, Omp16 and Omp19), thus activating the immune response. This process can be altered by single nucleotide polymorphisms (SNPs) in TLR gene. This study aims to investigate whether the presence of SNPs in TLR2 could influence the resistance against brucellosis in Italian Mediterranean river buffalo, through case-control study and computational analysis. The study involved 194 Italian Mediterranean buffaloes, from three herds located in Caserta (Campania, Italy), grouped into 98 positive and 96 negative to brucellosis. Both groups, aged 40-90 months, were raised under similar environmental and management conditions to ensure consistency in the sampling.
resultsThe integration of association study with in silico analysis demonstrated that the c.374T, located in exon 2 of the TLR2 gene, could be associated with resistance to brucellosis (OR = 0.61; p-value = 0.037).
conclusionsThis study highlights how TLRs genetic variations may influence protein activity and resistance to brucellosis. The genotyping analysis combined with in silico investigation could be considered an efficient approach for detecting possible candidate marker of resistance to buffalo brucellosis.
