Abstract Background: Mycobacterium avium complex (MAC) is a major cause of pulmonary nontuberculous mycobacterial disease; however, treatment outcomes remain suboptimal. Phenotypic drug susceptibility testing (DST) is conditionally recommended; however, conventional broth microdilution is labor-intensive. The Sensititre SLOMYCO® panel offers a standardized platform for DST

Abstract Although intestinal parasites are no longer considered a significant public health concern in Korea, tissue-invading parasites continue to pose clinical challenges. The diagnosis of tissue helminthiasis by recovering worms or larvae from tissues is invasive; therefore, serodiagnosis is widely used to diagnose infections caused by tissue-invading parasites. Among the serological tests, the enzyme-linked immunosorbent assay (ELISA) is the most commonly used, and various antigens, including crude antigens, excretory-secretory antigens of helminths,
