1. Swine Dysentery: Brachyspira hyodysenteriae is the primary causative agent of swine dysentery, also known as bloody scours or hemorrhagic colitis in pigs. This disease is characterized by severe diarrhea, often containing blood and mucus, along with weight loss, dehydration, and decreased feed intake. Swine dysentery can lead to substantial economic losses in pig production due to reduced growth rates, increased mortality, and costs associated with treatment and control measures.

2. Colonization of the Large Intestine: Brachyspira hyodysenteriae colonizes the large intestine (specifically the colon) of pigs, where it adheres to and damages the colonic mucosa, leading to inflammation and diarrhea. The bacteria produce toxins and enzymes that contribute to the pathological changes observed in the intestinal mucosa and the clinical signs of swine dysentery.

3. Transmission: Swine dysentery is highly contagious and spreads among pigs through the fecal-oral route, primarily via direct contact with infected feces or contaminated environments. The bacteria can survive in feces and the environment for extended periods, facilitating transmission within and between pig herds.

4. Impact on Production and Welfare: Swine dysentery can have significant negative impacts on pig health, production, and welfare. Infected pigs experience discomfort and pain due to the severity of diarrhea and colonic inflammation, leading to reduced performance, compromised welfare, and increased susceptibility to other diseases.

5. Control and Management: Control of swine dysentery typically involves a combination of management practices, biosecurity measures, and antimicrobial treatment. Strategies may include strict hygiene protocols, segregation and isolation of affected animals, sanitation of facilities, and targeted use of antimicrobials to control outbreaks and reduce bacterial shedding. However, antimicrobial resistance in Brachyspira hyodysenteriae has become a concern, highlighting the importance of judicious antibiotic use and alternative control strategies.

Lab Reporting

Different labs use different software to read the sample. See this post for more details.
One lab may say you have none, another may say you have a lot! - This may be solely due to the software they are using to estimate.
We deem lab specific values using values from the KM method for each specific lab to be the most reliable.

Desired Levels Suggestions for Brachyspira hyodysenteriae

• Lab Low and High are calculated using the formula that most labs use: Mean - 1.95 Standard Deviation to Mean + 1.95 Standard Deviation

These are values that are computed from lab specific samples and are in percentage
