Mycoplasma hyopneumoniae ( M. ) is considered the primary causative agent of porcine enzootic pneumonia (EP), a chronic contagious respiratory disease that causes economic losses. Obtaining new pathogenic isolates and studying genome virulence factors are necessary. This study performed complete sequencing analysis two Brazilian strains, UFV01 UFV02, aiming to characterize in terms sequence type. The revealed main genes mhp385 , mhp271 MHP_RS03455 p102 p97 p216 MHP_RS00555 mhp107 ST-123,...
Respiratory diseases, such as pleurisy and pneumonia, cause significant health economic losses in pig production. This study evaluated 867 finishing pigs from a farm with history of respiratory issues, using macroscopic lesion scoring (SPES CVPC), histopathological analysis, qPCR diagnostics, modeling. Severe (scores 3 4) was observed 42.1% carcasses strongly correlated higher bacterial loads Mycoplasma hyopneumoniae, Actinobacillus pleuropneumoniae, Pasteurella multocida. lesions reduced...
Mycoplasma hyopneumoniae is a difficult-to-control bacterium since commercial vaccines do not prevent colonization and excretion. The present study aimed to evaluate the performance of an orally administered vaccine composed antigens extracted from incorporated into mesoporous silica (SBA-15), which has adjuvant-carrier function, aiming potentiate action intramuscular vaccine. A total 60 piglets were divided four groups (n = 15) submitted different vaccination protocols as follows, Group 1:...
