Description
Renée Petri and three co-authors search the stomach microbiome of calves for a signature of perforated ulcers, in a 2026 Canadian study. Perforating ulcers of the abomasum, the fourth stomach, kill young beef calves and are usually found only after death. Microbes have been blamed on circumstantial evidence.
The team sequenced microbes from the stomach tissue of twenty-seven calves with ulcers and seventeen without. Overall community makeup did not differ significantly between the groups. A deeper sequencing pass on eighteen samples found the usual gut families at low levels everywhere. One Streptomyces species was less abundant in ulcer calves, hinting at a link to gut health. A resistance gene tied to a drug class appeared more in calves that had received antimicrobial treatment. Predicted metabolic functions differed numerically but not significantly. The authors call for larger studies before blaming any microbe.
