Haemophilus parasuis is an early colonizer of the porcine upper respiratory tract and is the etiological agent of Glasser’s disease. The factors responsible for H. parasuis colonization and systemic infection are not yet well understood, while prevention and control of Glasser’s disease continues to be challenging.
What causes Glasser's disease?
Glässer disease is caused by infection with Glaesserella (Haemophilus) parasuis. The most common form is characterized by fibrinous polyserositis and polyarthritis, but septicemia with sudden death and bronchopneumonia also can occur. Diagnosis is based on clinical signs and bacterial isolation or PCR.
What causes diamond skin disease?
Erysipelas in swine is caused primarily by Erysipelothrix rhusiopathiae, a bacteria carried by up to 50% of pigs. Possible clinical manifestations are cutaneous erythema, including characteristic diamond-shaped lesions, septicemia, arthritis, and endocarditis.
What is Glasser disease?
Definition. An infectious disease of pigs, often acute, characterized by various combinations of meningoencephalitis, polyserositis and polyarthritis as well as a contributor to bacterial pneumonia.
What is HPS in pigs?
Haemophilus parasuis (HPS) can contribute to clinical disease in pigs in three major ways: joint problems, pneumonia and multisystemic disease (Table 1). Although HPS is a common resident of the upper respiratory tract of pigs of all ages, most pigs can harbor HPS in their nose with no ill effects.
How do you treat greasy pigs?
- Determine the antibiotic sensitivity and inject affected piglets daily for five days, or on alternate days with a long-acting antibiotic to which the organism is sensitive to.
- Antibiotics include: amoxycillin, OTC, ceftiofur, cephalexin, gentamycin, lincomycin or penicillin.
What bacteria causes greasy pigs?
Greasy Pig Disease is a bacterial infection of the skin of the pig, which is known by a variety of other names – Greasy Skin, Exudative Epidermitis, Marmite Disease. The primary cause of the disease is Staphylococcus hyicus, which is a common bacterium known to colonise the skin of many pigs without causing disease.
What is atrophic rhinitis in swine?
Atrophic rhinitis is characterized by sneezing, followed by atrophy of the turbinate bones, which may be accompanied by distortion of the nasal septum and shortening or twisting of the upper jaw. Its significance has declined substantially, and it is no longer considered a major health risk to swine herds.
What causes classical swine fever?
Classical swine fever (CSF), also known as hog cholera, is a contagious viral disease of domestic and wild swine. It is caused by a virus of the genus Pestivirus of the family Flaviviridae, which is closely related to the viruses that cause bovine viral diarrhoea in cattle and border disease in sheep.
What is African swine fever?
African swine fever (ASF) is a highly contagious haemorrhagic viral disease of domestic and wild pigs, which is responsible for serious economic and production losses. It is caused by a large DNA virus of the Asfarviridae family, which also infects ticks of the genus Ornithodoros.

How do you treat diamond skin disease?
Treatment. The erysipelas organism is very sensitive to penicillin. Acutely ill animals should be treated with quick acting penicillin twice daily for three days. Alternatively a long-acting penicillin, given as a single dose to cover 48 hours of treatment, could be given and then repeated.
Where is erysipelas found?
Erysipelas is a relatively common bacterial infection of the superficial layer of the skin (upper dermis), extending to the superficial lymphatic vessels within the skin, characterized by a raised, well-defined, tender, bright red rash, typically on the face or legs, but which can occur anywhere on the skin.
Is erysipelas the same as cellulitis?
Erysipelas is a superficial infection, affecting the upper layers of the skin, while cellulitis affects the deeper tissues. They can overlap, so it is not always possible to make a definite diagnosis between the two.
What causes edema in pigs?
Edema disease is a peracute toxemia caused by specific pathotypes of Escherichia coli that affect primarily healthy, rapidly growing nursery pigs. Other names for edema disease include “gut edema” or “bowel edema” because of the prominent edema of the submucosa of the stomach and mesocolon.
What is erysipelas in pigs?
Swine erysipelas is an infectious disease caused by the bacterium Erysipelothrix rhusiopathiae seen mainly in growing pigs and characterised clinically by sudden death, fever, skin lesions and arthritis. The fever can induce abortion in pregnant gilts and sows.
What is pig Polyserositis?
Polyserositis is typically characterized by fibrinous or fibrinopurulent pleuritis, pericarditis, or peritonitis, frequently associated with arthritis and meningitis. Four- to 8-wk-old pigs are typically the most affected animals and, to a lesser extent, 3- to 4-mo-old pigs.
What does greasy pig disease look like?
The disease commonly occurs in piglets of between 7 days and 5 weeks of age. The clinical signs begin with listlessness, a dulling of the skin and the appearance of thin, pale brown flecks or scales on the skin surface. There is often scabbing of the cheeks or knees due to fighting or kneeling on rough floors.
How is greasy pig disease diagnosed?
(Greasy Pig Disease) Exudative epidermitis is a generalized staphylococcal infection that affects young pigs. Clinical signs include depression and reddening of skin, followed by rapid spread of exudative, nonpruritic pustules. Diagnosis is based on clinical signs and confirmed by bacterial culture of lesions.
Is greasy pig disease zoonotic?
It causes disease in poultry, cattle, horses, and pigs. Most notably, it is the agent that causes porcine exudative epidermitis, also known as greasy pig disease, in piglets. S. hyicus is generally considered to not be zoonotic, however it has been shown to be able to cause bacteremia and sepsis in humans.
How is mastitis treated in pigs?
- Oxytocin to let milk down (0.5ml).
- Antibiotics as prescribed by your veterinarian depending on the organism and its sensitivity. In very severe cases the sow should be injected twice daily. The following could be used: OTC; penicillin and streptomycin; trimethoprim/sulpha;
How do you prevent coccidia in pigs?

- Remove sow and piglet faeces daily.
- Improve the hygiene in farrowing houses, in particular farrowing pen floors and prevent the movement of faeces from one pen to another.
Is classical swine fever curable?
No treatment is available. Outbreaks in countries free of CSF are controlled rapidly via culling of infected animals and preemptive slaughter of susceptible animals within determined distances from the focus.
What is the difference between classical swine fever and African swine fever?
ASF is caused by a virus that is unrelated to the classical swine fever virus and has a more complex genetic structure. Both ASF and CSF affect pigs only, and do not infect humans and other livestock.
What are the symptoms of classical swine fever?
Signs of CSF vary with the strain of classical swine fever virus and the age and susceptibility of the pigs. High fever, huddling, constipation followed by diarrhea and reddened eyes are often seen. The skin may show hemorrhages with discoloration of the ears, abdomen or inner thighs.
How do you prevent atrophic rhinitis in pigs?
- Keep disease out by purchasing pigs only from known negative sources.
- Monitor snout sections regularly.
- If the herd is infected do not breed from home bred gilts.
- Vaccinate sows.
- Maintain an old herd to produce good colostral immunity.
What causes sneezing in pigs?
7.1a. This is an outbreak of sneezing, with nasal and eye discharges due to swine flu or orthomyxovirus influenza. This virus sets up a strong inflammatory reaction in the linings of the upper respiratory tract. The virus is then located and spread in the nasal secretions of infected pigs.
Which disease affects the turbinate bones in swine?
Atrophic rhinitis (AR) is the term com- monly used to refer to the condition of a sneezing pig with a crooked, bleeding snout and tear-stained face. The term “atrophic” means that the turbinate bones inside the snout are shrunken and distorted.

African swine fever is a highly contagious and deadly viral disease affecting both domestic and feral swine of all ages. ASF is not a threat to human health and cannot be transmitted from pigs to humans.
How is erysipelas diagnosed?
Share on Pinterest A blood test can reveal raised levels of white blood cells, which can indicate damage caused by an infection. In general, a doctor will be able to diagnose erysipelas by the appearance and symptoms of the affected area.
