Highly pathogenic avian H5N1 influenza A virus replication in ex vivo cultures of bovine mammary gland and teat tissues.
Article in Emerging microbes & infections, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Since early 2024, highly pathogenic avian influenza H5N1 viruses have been causing outbreaks in dairy cattle in the United States. Here, we compared the replicative capacity of A/dairy cattle/Texas/24-008749-001/2024 (H5N1; Cow-H5N1) isolated from a dairy cow, A/chicken/Ghana/AVL-76321VIR7050-39/2021 (H5N1; Chicken-H5N1) isolated from a chicken, and a human H1N1 2009 pandemic virus in ex vivo explant cultures of mammary gland and teat from lactating cows. We also examined the expression of influenza virus receptors in these organs. We observed that human influenza virus receptors are widely distributed throughout the epithelium of alveoli, ducts, and gland cisterns within the mammary gland, and in the teat cistern epithelium of dairy cattle, whereas avian influenza virus receptors are distributed on the alveolar, ductal, and teat cistern epithelium. We also found that Cow-H5N1 virus replicates more efficiently than Chicken-H5N1 or human H1N1pdm viruses in the gland cistern epithelium of dairy cattle. Notably, bovine H5N1 viruses replicated efficiently in the epithelium of the bovine teat cistern. These findings suggest that H5N1 viruses invade the mammary gland through the teat canal, which is easily accessed by viruses.
