Prevalence of granulomatous pleuropneumonia associated with Actinobacillus pleuropneumoniae serotype 2 in slaughter pigs.
A total of 14,818 slaughtered pigs were examined macroscopically. Of these, 25 pigs with porcine pleuropneumonia were collected and the relations among Actinobacillus spp. and granulomatous lesions in organs (lungs and tonsils) were evaluated. In the lungs, only Actinobacillus pleuropneumoniae serotype 2 was isolated from 20 of the pigs. Histologically, granulomatous pneumonia with A. pleuropne...
متن کاملSerotyping reanalysis of unserotypable Actinobacillus pleuropneumoniae isolates by agar gel diffusion test
We observed increasing unserotypable (UT) Actinobacillus pleuropneumoniae isolates using agar gel diffusion (AGD) test. To reanalyze their serovar, we performed rapid slide agglutination (RSA) test and multiplex PCR for 47 UT isolates. Of these, 25 were serovar 1 (UT-serovar 1), 20 were serovar 2 (UT-serovar 2) and 2 were serovar 15 (UT-serovar 15). We examined serotyping antigen extraction tem...
متن کاملPrevalence and Characterization of Actinobacillus pleuropneumoniae Isolated from Korean Pigs
Actinobacillus pleuropneumoniae causes porcine pleuropneumoniae which is one of severe threats to the swine industry. In total, 54 strains of Actinobacillus pleuropneumoniae were isolated from 443 pigs between 2012 and 2013 in Korea. Isolates were classified into serotypes 1, 2, 5, 7, 12, and unclassified by multiplex PCR. Genotypes of isolates were divided into three groups according to the se...
متن کاملIdentification and serotyping of Haemophilus pleuropneumoniae by coagglutination test.
A coagglutination test for the identification and serotyping of Haemophilus pleuropneumoniae is described. A total of 360 H. pleuropneumoniae strains were isolated from pulmonary tissues of feeder pigs which died of acute pleuropneumonia. All of the isolates were serotyped by coagglutination, and the results were confirmed by the ring precipitation test. The most common serotype isolated in Que...
متن کاملGarlic reduces effect of Actinobacillus pleuropneumoniae infection in pigs
Lung diseases in pigs are among the most important health problem in pig husbandry, and generally treated with antimicrobials. To reduce the amount of antimicrobials used in pigs, we tested the preventive effects of freeze dried garlic added to feed on an infection with Actinobacilluspleuropneumoniae (APP). Thirty male pigs of about seven weeks of age were aerosol challenged with APP serotype 2...
