Exploring the prevalence of M. hyorinis, M. hyosynoviae, and M. hyopneumoniae, across various age groups using various sampling techniques

Oral fluids PCR was a more sensitive test for detecting animals positive for M. hyorhinis and M. hyosynoviae, while Tween 20 ELISA should be used for M. hyopneumoniae.

PCV2 related diseases (PCVDs): risk factors analysis

It has been shown that the efficacy of PCV2 vaccines was dramatically decreased in the context of husbandry deviations such as excess of cross-fostering, mingling at weaning or very large groups in nursery.

Pleurisy: economic impact and strategies for management in swine farms

The prevalence of pleurisy is surprisingly high among pigs at slaughter. A recent review of available data ranged from 12.5% in the UK, 26% in Spain, to 41% of individual pigs slaughtered in one Norwegian study.

Abstract

Simultaneous PCV2 and Mycoplasma hyopneumoniae co-inoculation does not potentiate disease in conventional pigs

Under the conditions of the present study, concurrent inoculation of PCV2 and Mhyo did not result in potentiation of clinical signs and lesions attributed to either infection.

Clinical case: Outbreak of influenza in a PRRS and Mhyo stable herd

In July 2010 a severe respiratory disease occurred in the farm: coughing in gilts, and coughing and depression in fatteners concomitantly to an increase of the mean stillborn and mummified piglet rate in a batch of sows.

Prevalence of Mycoplasma hyopneumoniae infections at weaning age in European pig herds

To date, 64 out of the 150 tested herds (42.7%) and 175 out of the 3118 tested piglets (5.6%) tested positive for M.hyo.

A one-night downtime period prevents the spread of PRRS and Mycoplasma hyopneumoniae by personnel and fomites

This paper summarizes observations recorded over a 4-year period regarding the ability of a 1-night period of downtime to prevent mechanical spread of PRRS and Mycoplasma hyopneumoniae between pig populations by personnel and fomites.
