Transcriptome changes in Mycoplasma hyopneumoniae during infection.
Mycoplasma hyopneumoniae causes swine pneumonia and contributes significantly to the porcine respiratory disease complex. The mechanisms of pathogenesis are difficult to address, since there is a lack of genetic tools, but microarrays are available and can be used to study transcriptional changes that occur during disease as a way to identify important virulence-related genes. Mycoplasmas were ...
متن کاملEfficacy 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 کاملA field evaluation of two vaccines against Mycoplasma hyopneumoniae infection in pigs
BACKGROUND A field trial was carried out with two Mycoplasma hyopneumoniae vaccines in order to investigate the benefit of vaccination under field conditions in modern Danish pig production facilities with pigs being positive for M. hyopneumoniae. The M. hyopneumoniae infection of the herd was confirmed through blood samples that were positive for antibodies against M. hyopneumoniae combined wi...
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 کاملApplication of enzyme-linked immunosorbent assay for the surveillance of Mycoplasma hyopneumoniae infection in pigs.
A monoclonal antibody-based blocking enzyme-linked immunosorbent assay (ELISA) was used for serological surveillance of Mycoplasma hyopneumoniae infection in pig herds. A follow-up study was conducted on "herd predictive values" previously reported for this ELISA. Of those herds giving positive results by this ELISA, 42% were subsequently found to be infected, while 100% of herds giving negativ...
