Information on the biology and epidemiology of feline aelurostrongylosis is fragmentary, mainly due to the limits inherent in the classical diagnosis. In the present work, a two-step nested PCR based on the use of genetic markers in the second internal transcribed spacer (ITS2) of ribosomal DNA was established for\n            <jats:italic>A. abstrusus<\/jats:italic>\n            in different biological samples. Characterization of the ITS2 (321 bp of length) revealed a G+C content of 39.5%. To exploit the sequence difference between the ITS2 of\n            <jats:italic>A. abstrusus<\/jats:italic>\n            and those of other common feline endoparasites, specific primers were designed and tested by PCR for their specificities and sensitivities. The PCR assay was validated on a panel of fecal (i.e., feces, flotation supernatant, and Baermann sediment) and pharyngeal swab samples from cats with known histories of lungworm infections, and it showed a specificity of 100% and a sensitivity of up to 96.6%. Also, the nested PCR was able to identify cats that were actually infected but that tested negative by the classical diagnostic methods. This PCR method was shown to be a powerful tool for the molecular diagnosis of feline aelurostrongylosis, overcoming the constraints of the classical diagnosis. The implications of such a molecular tool for further bioepidemiological studies of both intermediate and definitive hosts have been discussed.\n          <\/jats:p>","DOI":"10.1128\/jcm.01612-07","type":"journal-article","created":{"date-parts":[[2008,3,27]],"date-time":"2008-03-27T01:00:42Z","timestamp":1206579642000},"page":"1811-1817","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":64,"title":["Diagnostic and Clinical Implications of a Nested PCR Specific for Ribosomal DNA of the Feline Lungworm\n            <i>Aelurostrongylus abstrusus<\/i>\n            (Nematoda, Strongylida)"],"prefix":"10.1128","volume":"46","author":[{"given":"Donato","family":"Traversa","sequence":"first","affiliation":[{"name":"Department of Comparative Biomedical Sciences, Faculty of Veterinary Medicine, Teramo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raffaella","family":"Iorio","sequence":"additional","affiliation":[{"name":"Department of Comparative Biomedical Sciences, Faculty of Veterinary Medicine, Teramo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Domenico","family":"Otranto","sequence":"additional","affiliation":[{"name":"Department of Public Health and Zootechny, Faculty of Veterinary Medicine, Valenzano, Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/nar\/25.17.3389"},{"key":"e_1_3_2_3_2","first-page":"163","year":"2000","unstructured":"Anderson, R.
