In Manitoba, Canada, several swine herds were infected by pandemic (H1N1) 2009 virus in the summer of 2009. Results of several investigations concluded that outbreaks of infection with this virus are similar in duration to outbreaks of infections with swine influenza viruses A (H1N1) and A (H3N2).

Between the years 2000 and 2004, 93,107 sera from 1,997 pig herds in 11 regions of Croatia were tested for the presence of antibodies against brucellosis. Positive results were observed in 67 herds from seven regions (mean individual prevalence: approximately 1%; herd prevalence: 3.4%). The herds from all but two of the infected farms were reared outdoors and thus almost certainly came into con...

Mycobacterium celatum, a slowly growing potentially pathogenic mycobacterium first described in humans, is regarded as an uncommon cause of human infection, though capable of inducing invasive disease in immunocompromised hosts. According to some reports, a serious disease due to M. celatum may also occur in individuals with no apparent immunodeficiency. In animals, an M. celatum-related diseas...

BACKGROUND The importance of the wild boar as a reservoir of Lawsonia intracellularis was assessed by investigating the seroprevalence of this pathogen among wild boars in the Republic of Korea. The extent of exposure to L. intracellularis among wild boars (Sus scrofa coreanus) was monitored by a country-wide serological survey using an immunoperoxidase monolayer assay. RESULTS In this study,...

Mitochondrial DNA (mtDNA) sequences (574 bp) of 30 Vietnamese pigs (large and small) were examined and compared with those of 61 haplotypes from wild boars and domestic pigs from various locations in Asia. The large Vietnamese pigs had genetic links to Ryukyu wild boars in southern Japan. The small Vietnamese pigs were closely related to other East Asian domestic pigs. These results indicate th...

Records collected during 1971 through 1979 from 101,606 pigs raised in 18 herds that were members of the Nebraska SPF Swine Accrediting Association were evaluated for phenotypic trends and predicted and observed genetic trends. Traits considered were backfat at 100 kg (BF) and weight at 140 d of age (WT). Phenotypic change on average was beneficial for BF (-.05 mm/yr) but undesirable for WT (-....

To clarify the epidemiology of influenza A viruses in coordinated swine production systems to which no animals from outside the system are introduced, we conducted virologic surveillance during September 2012-September 2013. Animal age, geographic location, and farm type were found to affect the prevalence of these viruses.

Microbial treatment of swine fecal waste to generate long-chain linear alkanes after fast pyrolysis" (2010).

The author explores the variations in the domestic livestock populations world-wide between 1961 and 1998, and observes a marked increase in the swine population, as compared to other domestic species. Trends in international trade of live animals over the same period are also analysed; international trade involved 1% of livestock world-wide and the international meat market constituted 10% of ...

Trichinellosis was recognized almost one century ago as a health and animal husbandry problem in Serbia. In the last 10 years, trichinellosis has been expanding from three endemic regions (Srem, Macva and Negotinska Krajina) to neighbouring regions. The infection rate detected by veterinary inspection in 1999 year was 0.17% in slaughtered swines. Simultaneously, the number of infected humans in...
