Efficacy of Mycoplasma hyopneumoniae vaccination before and at weaning against experimental challenge infection in pigs
BACKGROUND Commercial bacterins are widely used at weaning to control Mycoplasma hyopneumoniae infections in pigs. However, it is not known whether the efficacy of vaccinating against M. hyopneumoniae can be influenced by the weaning process when vaccination is applied at the day of weaning. The present study assessed the efficacy of a single M. hyopneumoniae vaccination (Ingelvac MycoFLEX®) th...
متن کاملEfficacy of one dose vaccination against experimental infection with two Mycoplasma hyopneumoniae strains
BACKGROUND Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary agent of enzootic pneumonia in pigs. Pigs are often infected with different M. hyopneumoniae strains. This study assessed the efficacy of vaccination against experimental infection with two genetically different M. hyopneumoniae strains in weaned piglets. At 33 days of age (D0), 45 M. hyopneumoniae-free piglets were randomly ...
متن کاملHerd specific risk factors for Mycoplasma hyopneumoniae infections in suckling pigs at the age of weaning
BACKGROUND Mycoplasma hyopneumoniae is the etiologic agent of enzootic pneumonia mainly occurring in fattening pigs. It is assumed that horizontal transmission of the pathogen during nursery and growing phase starts with few suckling pigs vertically infected by the sow. The aim of the present study was the exploration of the herd prevalence of M. hyopneumoniae infections in suckling pigs follow...
متن کاملEffects of Mycoplasma hyopneumoniae vaccination in pigs co-infected with M hyopneumoniae and porcine circovirus
Materials and methods: Weaned pigs (n = 296) were each vaccinated with one of three M hyo bacterins or a placebo and challenged 3 and 5 weeks after the second vaccination with M hyo and PCV2, respectively. A subset of pigs, necropsied 2 or 4 weeks after PCV2 challenge, were evaluated for clinical signs, lesions, PCV2 serum levels, and M hyo in bronchial alveolar lavage fluids. Antibody titers t...
متن کاملIndividual risk factors for Mycoplasma hyopneumoniae infections in suckling pigs at the age of weaning
BACKGROUND In recent years, the occurrence and the relevance of Mycoplasma hyopneumoniae infections in suckling pigs has been examined in several studies. Whereas most of these studies were focused on sole prevalence estimation within different age groups, follow-up of infected piglets or assessment of pathological findings, none of the studies included a detailed analysis of individual and env...
