DIAGNOSIS OF GIARDIASIS BY SPECIFIC IgM ANTIBODY ENZYME-LINKED IMMUNOSORBENT ASSAY

Peripheral Blood Lymphocyte Subsets in Infants with Diarrhea with and without Giardia Lamblia Infection

“…(Pediatr Res 33: [15][16][17][18]1993) Abbreviations NK, natural killer PBL, peripheral blood lymphocyte PE, phycoerythrin however, yielded inconclusive results. Whereas in some studies of acute giardiasis an anti-Giardia IgM response was noted (5,6), in others, an increase in specific IgA but not IgM or IgG antibodies was observed (7). Diminished cellular cytotoxicity for G. lamblia has been observed in a patient with symptomatic giardiasis resistant to drug therapy (8).…”

Entamoeba histolytica andGiardia lambliainfections: current diagnostic strategies

“…Unfortunately, most studies indicate that detection of anti-Giardia IgG does not readily distinguish between present and past infection (Farthing, 1994;Davis & Reynoldson, 1994). Both IgM and IgA responses are however relatively short-lived, and these may be of value in diagnosing an on-going infection (Goka et al, 1986;Nash et al, 1987;Goka et al, 1989).…”

“…Así, estudios previos demuestran que después de una infección se producen anticuerpos; los de IgM son los primeros en aparecer y se mantienen elevados entre dos y tres semanas (5). Los anticuerpos IgA permanecen elevados aún después de haberse tratado la infección (6) y los anticuerpos IgG se detectan en el 80% de los pacientes, respuesta que puede persistir por largos períodos (7).…”
