LAWSONIA INTRACELLULARIS Meaning and
Definition
-
Lawsonia intracellularis is a Gram-negative, obligate intracellular bacterium belonging to the family Desulfovibrionaceae. It is the causative agent of porcine proliferative enteropathy (PPE), a severe intestinal disease affecting pigs, as well as proliferative enteropathy in other animal species such as horses, rabbits, and rodents.
The bacterium is characterized by its ability to invade and multiply within the epithelial cells lining the intestines, leading to the formation of characteristic hyperplastic crypts and thickening of the intestinal walls. This pathological process results in severe diarrhea, weight loss, and reduced growth in affected animals.
Lawsonia intracellularis has a complex life cycle involving both extracellular and intracellular stages. The organism is shed through the feces of infected animals and can survive in the environment for extended periods. Transmission primarily occurs through the ingestion of contaminated feed or water.
Diagnosis of Lawsonia intracellularis infection is typically achieved through the detection of the bacterium in intestinal tissues using techniques such as polymerase chain reaction (PCR) or immunohistochemistry. Treatment options may include the use of antibiotics, specifically antibiotics that target intracellular bacteria.
Prevention and control of Lawsonia intracellularis infections involve good hygiene practices, proper sanitation of animal housing facilities, and the development of vaccination protocols. Vaccines against PPE have been developed and can be administered to susceptible animals to provide protection against infection.
In conclusion, Lawsonia intracellularis is a pathogenic bacterium responsible for causing proliferative enteropathy in various animal species, resulting in significant economic losses in the livestock industry.

Etymology of LAWSONIA INTRACELLULARIS
The word "Lawsonia intracellularis" is a scientific name used to refer to a specific bacterium known to cause a disease called proliferative enteropathy in animals, especially pigs. It is named after the scientist who first discovered and described the bacterium, Dr. David Lawson.
The term "intracellularis" in the name refers to the bacterium's unique ability to invade and replicate inside the cells of the host animal, particularly in the intestinal lining. This characteristic is significant as it distinguishes Lawsonia intracellularis from other bacteria and pathogens that may affect the gastrointestinal tract.
In summary, the word "Lawsonia intracellularis" combines the name of the scientist who identified the bacterium (David Lawson) with a descriptive term reflecting its intracellular nature.
