Adaptive immunity 



Humoral (Abs.) -pyogenic bacteria. -some virus & protozoos (luminal) Cellular (cells & cytokines) -Many fungi -Many viruses -Other intracytoplasmic microbs

IMMUNE DEFICIENCY SYNDROMES. II.- PRIMARY: - CHARACTERISTICS - COMMON INHERITANCE - SPECIFIC VS NONSPECIFIC - TYPES OF INFECTION

PATHOGENESIS OF PRIMARY IMMUNEDEF.

IMMUNE DEFICIENCY SYNDROMES. II.- PRIMARY: RECOMMENDED STUDY: - X-LINKED AGAMMAGLOBULINEMIA - COMMON VARIABLE IMMUNODEF. - ISOLATED IgA DEF. - DiGEORGE SYNDROME - SEVERE COMBINED IMMUNODEF.

BRUTON’S AGAMMAGLOBULINEMIA

GIARDIA LAMBLIA

Mycoplasma & Arthritis

COMMON VARIABLE IMMUNODEFICIENCY DIFFERENCES (W/BRUTON’S): - GENDER - Ig LEVELS - PERIPHERAL B CELLS - CLINICAL – HERPES INF. - AUTOIMMUNE DIS. - MALIGNANCIES

ISOLATED IgA DEFICIENCY DIFFERENCES (W/BRUTON’S): - EPIDEMIOLOGY - Ig TYPES - FAMILIAL OR ACQUIRED - Ab VS IgA - GENDER, PERIPHERAL B CELLS, AUTOIMMUNE DIS.
