The distribution of the organism was centered on the airways, and extended progressively with age from the alveolar ducts to the alveoli. In a retrospective immunohistochemical study of 245\u00a0newborn to adult pigs which were necropsied between 1988 and 1995, P carinii infection was found in 87 pigs (35\u20105 per cent) aged between 17\u00a0days to seven months. In the pigs aged between one and three months the infection rate was 63\u20101 per cent. Pigs from herds in which suckler and weaner pigs shared the same air space were more heavily infected than those from the herds in which they were reared separately. There were no regional or seasonal variations in the level of infection, and the infection was not associated with any single disease.<\/jats:p>","DOI":"10.1136\/vr.147.19.544","type":"journal-article","created":{"date-parts":[[2010,10,8]],"date-time":"2010-10-08T14:05:40Z","timestamp":1286546740000},"page":"544-549","source":"Crossref","is-referenced-by-count":21,"title":["Immunohistochemical study of Pneumocystis carini infection in pigs: evaluation of Pneumocystis pneumonia and a retrospective investigation"],"prefix":"10.1002","volume":"147","author":[{"given":"H.","family":"Kondo","sequence":"first","affiliation":[{"name":"Ishikari Livestock Hygiene Service Center 3 Ban, Hitsujigaoka Toyohira Sapporo Hokkaido 062\u20100045 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Ito","sequence":"additional","affiliation":[{"name":"Central Institute for Experimental Animals Nogawa Miyamae Kawasaki 216 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Kadota","sequence":"additional","affiliation":[{"name":"National Institute of Animal Health Hokkaido Branch Hitsujigaoka Toyohira Sapporo Hokkaido 062\u20100045 Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2000,11,4]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/path.1711640212"},{"key":"e_1_2_6_3_1","first-page":"407","article-title":"Pneumocystis carinii pneumonia in Danish piglets","volume":"127","author":"BILLE\u2010HANSEN V.","year":"1990","journal-title":"Veterinary Record"},{"key":"e_1_2_6_4_1","doi-asserted-by":"crossref","first-page":"2670","DOI":"10.1128\/jcm.35.10.2670-2672.1997","article-title":"Natural transmission of Pneumocystis carinii in nonimmunosuppressed animals: early contagiousness of experimentally infected rabbits (Oryctolagus cuniculus)","volume":"35","author":"CERE N.","year":"1997","journal-title":"Journal of Clinical Microbiology"},{"key":"e_1_2_6_5_1","first-page":"262","article-title":"Pathogenesis of porcine reproductive and respiratory syndrome virus infection in mid\u2010gestation sows and fetuses","volume":"57","author":"CHRISTIANSON W.
