Swine health
Pig diseases can be caused by bacteria, viruses, protozoa, nutritional deficiencies, poisonous substances, internal and external parasites.
Bacterial diseases include swine erysipelas, swine dysentery, infectious poly-arthritis etc. Viral and mycoplasma diseases include African swine fever, swine influenza, enzootic pneumonia of pigs, vesicular exanthema of swine, transmissible gastroenteritis etc. Helminthiasis as a health problem in pigs is mainly caused by worms like the lungworm, ascaris worm etc. Nutritional diseases include piglet anemia, parakeratosis etc. External parasitic infections include mange, lice, jiggers etc.
How to tell that a pig is in bad health:
General signs: dullness, loss of appetite, labored or rapid breathing, sudden deaths, loss of weight, low weight gain and fever usually manifested by shivering of the pig.
Signs expressed on the skin: reddening of the skin or skin discoloration, loss of hair and hardening of some parts of the skin, itching and cracking of the skin.
Other signs: lameness, cough, abnormal nasal discharges, diarrhea with a putrid smell, abnormal content and color of feces and abortions.
The favorable climate and low initial investment account for the popularity of raising pigs in dirt lots in the southeastern USA. The raising of swine on dirt, however, can pose several problems. One of these problems is that internal parasites (worms) are difficult to control, in particular in lots used over and over for swine. These parasites can cause swine to grow slowly and be unthrifty, and in severe cases can even kill swine. Fortunately, there are various chemical dewormers available...

1. Introduction Increased recognition of the consequences of antimicrobial resistance (AMR) in humans and animals has led to monitoring and surveillance programs in many countries, often specific to the species being monitored [1]. They range in complexity from highly structured and regulated systems to those that are passive or reactive. Except for a few species of public health interest such as Salmonella spp. [2], current AMR surveillance for bacterial isolates recovered from...

Introduction Porcine epidemic diarrhea virus is a coronavirus of the alphacoronavirus genus. Identified as a viral agent distinct from transmissible gastroenteritis virus (Wood, 1977) and as a coronavirus (Pensaert and de Bouck, 1978), this virus is responsible for an enteric infection in pigs. Originally identified in England (Wood, 1977), PEDV is now a global pathogen. PEDV was first identified in the United States in 2013 (Stevenson et al., 2013) where it swept through pig...

The characterization of the microbiota diversity inhabiting particular mucosal surfaces or other body sites has been an active topic of research in recent years, due to the involvement in many vital processes. In the gut, the high microbial diversity has the potential to provide metabolic activities that the host lacks. Specifically, the gut microbiota of mammals has been shown to confer health benefits to the host through the production of digestible food components, inhibition and...

Introduction Streptococcus suis (S. suis) is a major porcine pathogen responsible for important economic losses to the swine industry. In fact, it is one of the main causes of bacterial death in post-weaned piglets, from 5 to 10 weeks of age. According to the Canadian Swine Health Information Network, S. suis-related diseases are the most common infectious problem reported in Canadian swine farms. In addition, the Monitoring and Analysis Working...

Introduction
Toxoplasmosis is an important foodborne disease worldwide. Its public health importance has been largely under-recognized, but recent evidence has shown that Toxoplasma gondii leads to a high burden of disease at global, regional and national level. The World Health Organization ranked toxoplasmosis as number 13th among 31 foodborne diseases globally, also demonstrating regional differences, with for example a relative...

Introduction The controversy that disease was transmitted by invisible life forms stretches back centuries dating to Aristotle (300BC) who believed that all life originated from soil and Virgil (40BC) who believed that bees came from honey and maggots originated from warm meat. It was Spallanzani who showed that no maggots arose from boiled meat while others showed that simple cotton filters could prevent spontaneous generation of life from warm meat. The...

Introduction Parasites have long been neglected but nowadays are becoming more recognized as important foodborne pathogens. Various factors contribute to their undervaluation such as complex lifecycles and transmission routes, prolonged incubation period and chronic disease manifestations. In addition, rapid and sensitive diagnostic assays are not always available and therefore parasite occurrences are often underreported, resulting in low disease...

Introduction
The founding objectives of the IPVS were to provide a forum for exchanging ideas and information concerning pig health and disease, to encourage the formation of pig veterinary societies in all countries and to foster cooperation among them. In 1969, Dr. Tom Alexander chaired the Organizing Committee of the inaugural IPVS congress in Cambridge, UK. Tom embodied and shaped the soul of the IPVS by melding an eminent scientific...

Antimicrobial resistance (AMR) is a global concern, for both animal health and public health. Estimations of the burden of AMR predict that 10 million people will die annually in 2050 when no action is taken now. Many resistant bacteria (or resistance genes) can cross species barriers, and therefore exchange of resistant bacteria and resistance genes between humans, animals and the environment occurs frequently. Most obvious is the transfer of AMR from animals to humans...

Talk about traditional bacteria in pigs, and Mycoplasma hyopneumoniae (M. hyopneumoniae) will be among the first ones to be mentioned. The “tradition” of this microorganism may be based on the fact that it has been recognized as a swine-specific pathogen for more than five decades, that it is prevalent in most areas where pigs are raised, and that it is common to accept its circulation in pig herds....

An important work function for the practicing veterinarian is to solve various problems in swine herds. Diagnostics and making a diagnosis are an important part of solving a problem.
The diagnosis is central for describing the problem, identifying the problem and, finally, making a change that will hopefully lead to the problem being solved.
A diagnosis can either be made for individual animals or,...

Introduction Resilience was historically ignored in commercial swine breeding programs. One reason was that breeding companies need to supply high health animals to the commercial sector of the swine industry. Nucleus herds needed to be naïve or at least negative for major diseases such as porcine reproductive and respiratory syndrome virus (PRRSv), Actinobacillus pleuropneumoniae (APP), Mycoplasma hyopneumonaie , and other major diseases....

One of the most common issues in modern pig production systems worldwide is the presence of gastric ulcers. Mortality as high as 1% can be attributed to gastric ulcers in grow-finish pigs and sows, although ulcers impact pigs at every stage of production. (Can Vet J. et al., 2002) How can producers, feed specialists and veterinarians help pigs experiencing gastric ulcers? The answer may include feeding plasma derived functional proteins to light weight and at-risk pigs either by mixing...

INTRODUCTION In 2016, 63% of U.S. market hog sales originated in Iowa and the surrounding six states (USDA, 2017). While Midwest swine production is in a unique position of being favorably located geographically, such density increases the risk of disease transmission among farms. Porcine reproductive and respiratory syndrome virus ( PRRSV) is the costliest disease facing pig producers. Holtkamp et al. (2013) estimated annual losses of 664 million U.S. dollar...
