During the summer of 2022\u20132023 in Argentina and Uruguay, an explosive infestation of these insects occurred in pastures in which ruminants were grazing. This was believed to be associated with a severe drought, which had significantly reduced the flowering of crops. Three farms in Uruguay and one in Argentina were visited to examine the flocks and perform autopsies. Affected sheep had watery diarrhea, anorexia, depression, and ruminal atony. The average morbidity, mortality, and case fatality rates were 7.5%, 4.3%, and 68%, respectively. The main gross findings in all animals were in the jejunum; the serosa had multifocal hemorrhages, and the mucosa was necrotic and covered by a pseudomembrane. Microscopically, the mucosa had partial-to-complete necrosis of the lamina propria, as well as loss of villus and crypt epithelium with neutrophilic infiltration. Overlying the necrotic mucosa was a pseudomembrane of fibrin, cell debris, desquamated epithelial cells, degenerate neutrophils, and bacteria. Many specimens of A. atromaculatus were in all paddocks in which sheep grazed, as well as in the ruminal content of the autopsied animals.<\/jats:p>","DOI":"10.1177\/10406387241249180","type":"journal-article","created":{"date-parts":[[2024,5,6]],"date-time":"2024-05-06T05:30:30Z","timestamp":1714973430000},"page":"573-578","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Spontaneous intoxication of sheep by the pollen beetle\n                    <i>Astylus atromaculatus<\/i>\n                    : 4 outbreaks in Uruguay and Argentina"],"prefix":"10.1177","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7902-8676","authenticated-orcid":false,"given":"Carolina","family":"Matto","sequence":"first","affiliation":[{"name":"Ministerio de Ganader\u00eda, Agricultura y Pesca (MGAP), DILAVE \u201cMiguel C.
