Pathophysiologic correlates of acute porcine pleuropneumonia

American Journal of Veterinary Research, 2000
Abstract Objective—To develop and evaluate an in vivo model to study early events in the pathogenesis of acute porcine pleuropneumonia. Animals—Thirty-six 6- to 8-week-old pigs. Procedure—Pigs were inoculated intranasally or endotracheally with Actinobacillus pleuropneumoniae; inoculation routes were compared by evaluation

Porcine Haemophilus pleuropneumonia: Microbiologic and pathologic findings

Journal of the American Veterinary Medical Association, 1984
SUMMARY Haemophilus pleuropneumoniae was isolated from 11% of porcine lung specimens submitted to the University of Illinois Diagnostic Laboratory during 1979-1982. Acute necrotizing fibrinous bronchopneumonia was the most common diagnosis; 65% of lungs had severe involvement of the caudal lobes; 10% of lungs had unilateral involvement only.

Toxicity of Haemophilus pleuropneumoniae to porcine lung macrophages

Veterinary Microbiology, 1989
Viable Haemophilus pleuropneumoniae bacteria were toxic for porcine alveolar macrophages in vitro. This cytotoxic effect proved to be dose-related. A cell-free extract of H. pleuropneumoniae, heat-killed bacteria, and a Pasteurella multocida field strain were nontoxic. When macrophages were cultured with H.

Role of Haemophilus pleuropneumoniae lipopolysaccharide endotoxin in the pathogenesis of porcine Haemophilus pleuropneumonia

American Journal of Veterinary Research, 1987
SUMMARY Intact Haemophilus pleuropneumoniae cells (strain Shope 1, serotype 1), highly purified lipopolysaccharide (lps) obtained from this strain of H pleuropneumoniae, as well as from Escherichia coli 0111:B4, filter-sterilized H pleuropneumoniae cell-free culture supernatant fluid, and heat-inactivated supernatant fluid were given intranasally to ...

AN OUTBREAK OF PORCINE PLEUROPNEUMONIA DUE TO HAEMOPHILUS PARAHAEMOLYTICUS

Australian Veterinary Journal, 1979
An outbreak of porcine pleuropneumonia in an intensive piggery in south-eastern Queensland is described. Haemophilus parahaemolyticus was isolated from weaner piglets at post-mortem examination. The disease began in weaners and later occurred in suckling piglets 3 weeks of age.

Detection and localization of ApxI, -II and -III genes of Actinobacillus pleuropneumoniae in natural porcine pleuropneumonia in natural porcine pleuropneumonia by in situ hybridization.

Veterinary pathology, 2001
In situ hybridization techniques that employed a nonradioactive digoxigenin-labeled probe were used to detect and localize ApxI, II and III genes in tissue sections of pneumonic lung naturally infected with Actinobacillus pleuropneumoniae. In pigs infected with either serotype 2 or 6, a hybridization signal for apxIICA, apxIIICA, apxIBD, and apxIIIBD ...

Necrosis from needlestick injury with live Actinobacillus pleuropneumoniae porcine vaccine

BMJ, 2011
Actinobacillus pleuropneumoniae causes porcine pleuropneumonia, a highly infectious and commonly lethal disease in pigs.1 It is present in porcine respiratory tract wherever pig production is industrialised, but it is not considered to be zoonotic.2 To our knowledge, no cases of infection have been reported in animals other than pigs or in humans ...

Experimental reproduction of acute lesions of porcine pleuropneumonia with a haemolysin-deficient mutant of Actinobacillus pleuropneumoniae

Veterinary Record, 1991
The role of the heat-labile haemolysin of Actinobacillus pleuropneumoniae in acute porcine pleuropneumonia was examined. A virulent strain was compared with an isogenic haemolysin-deficient mutant in experimental infections. The pigs which received the virulent strain showed clinical signs of acute respiratory disease whereas the animals infected with ...

Oral immunization against porcine pleuropneumonia using the cubic phase of monoolein and purified toxins of Actinobacillus pleuropneumoniae

Vaccine, 2014
The main goal of this work was to obtain an orally administered immunogen that would protect against infections by Actinobacillus pleuropneumoniae. The Apx I, II and III toxins were obtained from the supernatants of cultures of serotypes 1 and 3 of A. pleuropneumoniae.

Antigenic relationship betweenHaemophilus influenzae andHaemophilus isolated from porcine pleuropneumonia

Current Microbiology, 1979
Comparative double immunodiffusion techniques were used to study capsular and O antigenic relationships betweenHaemophilus influenzae types a-fandH. pleuropneumoniae types 1–5 and a strain (202) closely related toH. pleuropneumoniae. Culture fluids or culture supernatants were used as antigens and rabbit antisera were produced against cell suspensions ...
