Actinobacillus pleuropneumoniae is a Gram-negative bacterium and the causative agent of porcine pleuropneumonia, highly contagious disease pigs characterised by fibrinohaemorrhagic necrotising pneumonia. Although it has been well controlled in some developed countries, outbreaks can occur all ages contact with asymptomatic carriers, leading to significant economic losses swine industry due high...

1. Among eight strains or variants, included in four different immunological types of pleuropneumonia-like microorganisms, all grew on chorioallantoic membranes; those belonging to Klieneberger's Type L(5) (Sabin Type A) grew very poorly; and those included in three other types grew with varying degrees of vigor. 2. In all instances, strains of pleuropneumonia-like microorganisms tested grew be...

BACKGROUND Septic pleuropneumonia is a common cause of morbidity and mortality in horses, but there is limited data available regarding factors associated with survival. HYPOTHESIS/OBJECTIVES To identify factors predictive of survival in horses with septic pleuropneumonia. ANIMALS A total of 97 horses with septic pleuropneumonia at 2 referral institutions. METHODS A retrospective study wa...

Some strains of pleuropneumonia-like organisms (PPLO) of human origin grow quite sparingly in vitro; therefore, attempts were made to determine if these organisms could be sustained better in the developing chick embryo. A semiquantitative comparison of growth on artificial media and in the chick embryo is presented. As pleuropneumonia-like organisms aIe frequent inhabitants of the genitourinar...

Smith, Paul F. (University of Pennsylvania, Philadelphia) and George H. Rothblat. Comparison of pleuropneumonia-like and L-type organisms. J. Bacteriol. 83:500-506. 1962.-The content of total lipid and nonsaponifiable lipid depended upon the type of organism; the greatest amounts were found in pleuropneumonia-like organisms that required cholesterol for growth and in L-1, the L-form of Streptob...

The isolation of organisms of the pleuropneumonia group from the human genital tract has aroused considerable interest in view of the attention now being paid to the aetiology of non-specific (non-gonococcal) urethritis. The first isolation of a pleuropneumonia-like organism from man was made by Dienes and Edsall (1937) from a Bartholin's abscess. Dienes and his associates (Dienes, 1940; 'Diene...

Langenfeld, M. G. (University of South Dakota, Vermillion) and P. F. Smith. Phosphorus distribution in pleuropneumonia-like and L-type organisms. J. Bacteriol. 86:1216-1219. 1963.-Sterol-requiring and sterol-nonrequiring pleuropneumonia-like organisms, salt-requiring and salt-nonrequiring L forms, and their parent bacteria, were analyzed for total, acid-soluble, lipid, and nucleic acid phosphor...

this study was carried out at the razi institute during 2005-2006 with inspecting 12168 lung tissue of slaughtered sheep and goats at the ziaran abattoir. pneumonia were diagnosed in 282 cases and the affected lung tissue was collected and transferred to the bacteriology and pathology departments for isolating of pasteurella spp. and interpretation of histopathologic lesions. pasteurella multoc...

Contagious caprine pleuropneumonia (CCPP) is now a well-defined disease that is caused by Mycoplasma capricolum subsp. capripneumoniae. CCPP is infectious, contagious and fulfils the classic Koch postulates that characterise such types of disease. The distribution of the disease is not exactly known, but reports of mycoplasma isolation and official declarations to the Office International des E...
