Final answer:
Reactive arthritis is a condition that develops following an enteric or genitourinary infection by certain pathogens such as Salmonella and Shigella, leading to joint pain and inflammation. Diagnosis and treatment involve synovial fluid analysis and antimicrobial therapy.
Step-by-step explanation:
The type of arthritis that appears to be precipitated by enteric infection caused by pathogens such as Salmonella, Shigella, Yersinia, and CHLAMYDIA is known as reactive arthritis.
Reactive arthritis is an inflammatory condition that affects the joints and may develop following an infection in another part of the body, particularly gastrointestinal or genitourinary infections. This form of arthritis is characterized by pain, swelling, and inflammation in the joints, and can lead to chronic symptoms if not properly addressed. Diagnosis typically involves the analysis of synovial fluid from the affected joint through aspiration, providing direct microscopic evaluation, culture, and testing for pathogens using methods such as PCR. Treatment is usually managed with antimicrobial therapy suitable for the identified pathogen, but it's important to note that some patients may suffer long-term joint damage despite treatment.
