Porcine Health Management

For a long time regarded as a commensal, Mycoplasma hyorhinis is now suspected to play an important role in PRDC, arthritis and polyserositis. The aim of the present study was to evaluate the way of diffusion of M. hyorhinis among suckling piglets in two...

Contact with new microbes may be dangerous for pigs of high heath status. This manuscriptdescribes a disease outbreak following allocation of SPF pigs.

Streptococcus suis infections are important indications for antimicrobial treatment in pigs. To control S. suis infections, it will be helpful to develop a practical test to assign a S. suis-status to farms. In this research we addressed the following...

The role of corvid birds in the epidemiology of Brachyspira hyodysenteriae causing swine dysentery in pigs has been questioned. Therefore, we examined crows living close to <i>B. hyodysenteriae</i> positive pigs for the presence of <i>B. hyodysenteriae...

Brachyspira (B.) hyodysenteriae infection can cause swine dysentery (SD), increased use of antimicrobials and economic losses. Control and eradication of SD rely on a better understanding of sources, transmission and spread. We analysed B. hyodysenteriae...

Erysipelothrix rhusiopathiae (ER) causes erysipelas and the tonsils are recognized as a common site for ER in pigs. The aim of this study was to estimate the incidence of ER in the tonsils of pigs in Sweden.   Material & Methods</strong> Tonsils were...

The Bacillus cereus cyclic depsipeptide cereulide is known to evoke emesis a short time after ingestion in humans, but besides this generally mild course of the disease, also severe clinical cases leading to death associated with liver failure and...

Here we present the analysis of samples of diarrhoea from new borne piglets (max. 4 days old) gathered by veterinarians and analysed at IVD laboratory in Hannover, Gernamy. Sampling kits were profided by IDT Biologika, containing 3 swabs and the sample...

Post-weaning Escherichia coli diarrhea (PWD) remains a major cause of economic losses for the pig industry. PWD, caused by enterotoxigenic <i>E. coli</i> (ETEC), typically provokes mild to severe watery diarrhea (5-10 days post-weaning). Most common...

FTA technology allows safe and practical storage and transportation of biological samples. However, its usefulness must be demonstrated with each new kind of sample. This study aimed to validate the use of FTA cards to detect the VT2e gene of verotoxigenic Escherichia coli (VTEC) in pig oral fluid by qPCR.

Actinobacillus pleuropneumoniae</i> (APP) is the causative agent of porcine pleuropneumonia. Diagnosis is often done via serological investigations, with slaughterhouse checks as complementary tool. This study compares pleurisy at slaughter with serological response in herds with and without clinical signs of APP.  

Understanding duration of M. hyopneumoniae (Mhp) shedding in swine populations determines the the duration of herd closure for elimination and gilt exosure timing for Mhp acclimation strategies. Although shedding duration in experimentally infected pigs is known, epidemiology of natural Mhp infection remains unknown. This study describes the pattern of natrual Mhp infection and persistence in a gilt population.  

S. suis is a significant zoonotic pathogen affecting pigs and humans. Quick and correct antimicrobial treatment implementation increases recovery chances. Antimicrobial resistance (AMR) can be predicted by the presence of certain genes conferring resistance. The dynamics of horizontal gene transfer often mean that AMR genes are found within the same mobile elements such as transposons.

Actinobacillus pleuropneumoniae (APP) is a common respiratory pathogen, but the incidence is generally unknown. This study aimed to screen the presence of APP in Swedish multiplying herds.

The use of PCR analysis to detect Mycoplasma hyopneumoniae (Mhp) in live pigs provides information about the infection dynamics and it may allow the identification of infected pigs before seroconversion, observation of clinical signs and lung lesions. Besides, laryngeal swabs tested by PCR have proved to be a reliable diagnostic sample for Mhp detection in vivo during early-stage infection. The objective of this study was to investigate the potential association between early detection of Mhp in laryngeal swabs and lung lesions in pigs experimentally infected with Mhp.
