Introduction Salmonella is a worldwide-distributed pathogen that affects both humans and animals 13 . This microorganism is usually associated with intensive animal production, such as swine, since the confinement of animals facilitates the transmission and persistence of the pathogen in farms. Salmonellosis may cause significant economic losses due to mortality, morbidity, stunted growth, increased feed conversion rates and costs of non-specific...

1. Introduction The first set of cases of African swine fever (ASF) in Latvia were detected in the wild boar population at the eastern border with Belarus in June 2014 [1–3]. The disease continued to spread over most of the territory of Latvia within the following years [4–6]. Similar to other ASF affected countries, the infection cycle is maintained by wild boar and this remains a permanent threat for the domestic pig industry [1,7,8]. In parallel, to the epidemic...

In a recent panel with Farm Journal, three experts shared their insights on African Swine Fever and the lessons learned from the effects of the ongoing COVID-19 pandemic.
Gordon Spronk (President of Pipestone Veterinary Services) mentioned that “ASF continues to spread across the globe. It was a threat when it was found in the world’s largest swine population in China and continues to be a threat now.”
Spronk added: “Our vision is to keep it out of our...

1. Introduction African swine fever (ASF), a fatal disease in domestic pigs and wild boar, has become a serious economic threat to the pig farming sector with global ramifications, more than ever underlined by the recent spread to China, Mongolia and Southeast Asia [1]. It is causing tremendous losses in the industrial pig sector but also affecting livelihood of small-scale pig holders in rural areas. In 1921, the disease was first described in Africa, where the disease...

1. Introduction Astroviruses are emerging viruses in the family Astroviridae, which is divided into two genera: Avastrovirus andMamastrovirus[1]. Astroviruses are non-enveloped, 28–30 nm positive-sense, single stranded RNA viruses [2] that can cause disease and be detected in the feces from a wide variety of mammals and birds [3–9]. Porcine astroviruses (PoAstVs) are genetically diverse and are distributed worldwide [10] with five genetic lineages...

1. Swine Melioidosis Melioidosis, an infection endemic to Southeast Asia, northern Australia, and other tropical areas, is caused by the soil-dwelling Gram-negative bacterium Burkholderia pseudomallei, which is known to contaminate water sources [1]. The infections are cyclic and correlate with rainy seasons, which may be due to environmental disruptions such as flooding. While creating a major health concern for humans, B. pseudomallei is also a threat to various animals...

Why was a review of the 2014 Canadian PEDV outbreaks conducted?
At the time of the 2014 Canadian PED outbreak, an extensive epidemiological investigation was initiated. The results of the investigation were published in a series of papers and are commonly cited when discussing the risk of spreading disease through feed and feed ingredients.
However, considering everything that has been learned about PED since that time, it is appropriate to review the...

Introduction Currently in Brazil there are no standardized housing systems for weaned pigs, and therefore, a big range of different facilities are observed in pig farms. Although some studies have evaluated individual risk factors related to health status and growth performance (MORES et al., 1998; DALLA COSTA et al., 2000), studies regarding the evaluation of risk factors in housing conditions and their interaction with...

As a result of COVID-19, veterinarians need to look at biosecurity in new ways. As practitioners we have to focus on protecting pigs and maintaining the economic viability of the farm. We are trained to deal with zoonotic diseases with a primary goal of protecting ourselves, our clients, and the food supply chain. Yet, now we are being asked to think more broadly, more holistically as an occupational (One Health) specialist, thinking about the health of farm employees, their families, and...

Coronavirus Disease 2019, also known as COVID-19, caused by the virus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a “person-to-person” disease. Efforts must be directed at protecting the health of personnel, and their families, involved in the care of animals, and supporting the operation of the farms, and the overall food production supply chain (e.g., feed distribution, feed mills, slaughter plants, truck drivers,...

Background The encephalomyocarditis virus (EMCV) is a nonenveloped positive single-stranded RNA virus. The EMCV serotype is a member of the Cardioviridae genus of the Picornaviridae family [1]. The virus is very resistant and stable in a wide pH-spectrum. The virus may be inactivated in water with 0.5 ppm chloride, iodine and mercury(II)chloride [2]. Infections with EMCV are demonstrated in multiple species, including humans [3]. The natural reservoir consists...
