Despite its importance, few studies investigating the epidemiological aspects of infection by this parasite have been conducted. The aim of this study was to report the occurrence of lungworm infection in beef cattle herds reared in an area of livestock production in the northeastern region of Brazil. From September 2020 to August 2021, monthly fecal samples (n = 493) were collected from 46 beef cattle. Among all the animals assessed, lungworm larvae were detected in 8.7% (4\/46). None of them presented any clinical sign suggestive of infection by lungworm parasites. Twenty larvae were retrieved, with the minimum number (n = 1) detected in October and December, and the maximum number (n = 13) in November. These presented a mean length of 363 \u03bcm (\u00b1 28.65 \u03bcm) and mean width of 19 \u03bcm (\u00b1 1.03 \u03bcm), and were morphologically similar to Dictyocaulus sp.. This study reports the occurrence of this parasite in this livestock production area. Lastly, local veterinarians need to be aware of inclusion of this parasite in the differential diagnosis of other respiratory infections in beef cattle.<\/jats:p>","DOI":"10.1590\/s1984-29612022047","type":"journal-article","created":{"date-parts":[[2022,8,22]],"date-time":"2022-08-22T09:03:39Z","timestamp":1661159019000},"source":"Crossref","is-referenced-by-count":4,"title":["Larvoscopic study on Dictyocaulus sp. in the faeces of beef cattle in northeastern Brazil"],"prefix":"10.1590","volume":"31","author":[{"given":"Lucia Oliveira de","family":"Macedo","sequence":"first","affiliation":[{"name":"Universidade Federal do Agreste de Pernambuco,  Brasil; Universidade Federal Rural de Pernambuco,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos Roberto Cruz","family":"Ubirajara Filho","sequence":"additional","affiliation":[{"name":"Universidade Federal do Agreste de Pernambuco,  Brasil; Universidade Federal Rural de Pernambuco,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renata Silva","family":"Brito","sequence":"additional","affiliation":[{"name":"Universidade Federal do Agreste de Pernambuco,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karlla Keyla Ferreira dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Universidade Federal do Agreste de Pernambuco,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla Lopes de","family":"Mendon\u00e7a","sequence":"additional","affiliation":[{"name":"Universidade Federal Rural de Pernambuco,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00edlcia Aparecida de","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Universidade Federal do Agreste de Pernambuco,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0347-9358","authenticated-orcid":false,"given":"Rafael Antonio Nascimento","family":"Ramos","sequence":"additional","affiliation":[{"name":"Universidade Federal do Agreste de Pernambuco,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2022]]},"reference":[{"issue":"11","key":"ref1","doi-asserted-by":"crossref","first-page":"853","DOI":"10.1016\/S1995-7645(12)60159-X","article-title":"Study on small ruminant lungworms and associated risk factors in northeastern Iran","volume":"5","author":"Borji H","year":"2012","journal-title":"Asian Pac J Trop Med"},{"issue":"7","key":"ref2","doi-asserted-by":"crossref","first-page":"1286","DOI":"10.1590\/1678-5150-pvb-5225","article-title":"Gastrointestinal and pulmonary nematodes in calves naturally infected in the cities of Botucatu and Manduri, in the Brazilian state of S\u00e3o Paulo.
