Herd 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 کاملMycoplasma Hyopneumoniae - Epidemiology and Control
Respiratory disease is an economically devastating syndrome affecting swine production worldwide. Mycoplasma hyopneumoniae (M. hyo) is a key pathogen involved with enzootic pneumonia (EP) and the Porcine Respiratory Disease Complex (PRDC). Enzootic pneumonia is composed of M. hyo and secondary bacteria such as Pasteurella multocida, Streptococcus suis, Haemophilus parasuis, and Actinobacillus p...
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...
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 کاملDiagnosis of Mycoplasma hyopneumoniae.
Mycoplasma hyopneumoniae, the cause of enzootic pneumonia, remains an important pathogen in the swine industry. This small, complex organism colonizes the ciliated cells of the respiratory tract, resulting in little exposure to the immune system. Confirming the presence of M. hyopneumoniae, as well as identifying its role in respiratory disease and pneumonia, remains challenging to the veterina...
