  1. BLOOD PARASITESPLASMODIA/ BABESIA WINIFREDA U. DELEON

  2. SPECIES PLASMODIUM FALCIPARUM PLASMODIUM VIVAX PASMODIUM MALARIAE PLASMODIUM OVALE PLASMODIUM KNOWLESI

  3. ARTHROPOD -BORNE ANOPHELES MOSQUITOES A. MINIMUS FLAVIROSTRIS HABITAT IN MAN – RBC HIGH OXYGEN TENSION COMPONENTS: NUCLEUS (CHROMATIN) CYTOPLASM

  4. ON THE MOSQUITO VECTOR NIGHT BITER SLOW FLOWING CLEAN STREAMS FOOTHILLS EXOPHAGIC ZOOPHILIC

  5. FORESTED AREAS- CLEANSLOW FLOWING STREAMS

  6. LIFE CYCLE SCHIZOGONY ASEXUAL MULTIPLICATION END PRODUCTS – SCHIZONTS (MEROZOITES) OCCURS IN MAN GAMETOGONY GAMETOCYTES OCCURS IN MAN SPOROGONY SEXUAL MULTIPLICATION END PRODUCTS – OOCYSTS (SPOROZOITES) OCCURS IN MOSQUITOES

  7. ASEXUAL STAGES TROPHOZOITES YOUNGEST - RINGFORMS DEVELOPING MATURE SCHIZONTS EARLY DEVELOPING MATURE - MEROZOITES

  8. TROPHOZOITES

  9. SCHIZONTS

  10. RED CELL DEFENSES CELL MEMBRANE DUFFY Ag NULL – RESISTANCE TO P. VIVAX HEMOGLOBIN -HEMOGLOBIN S (SICKLE TRAIT) HELPS IN THE SURVIVAL OF PATIENTS FROM P. FALCIPARUM PRIMARY ACUTE ATTACK -B-THALLASEMIA- IMBALANCED GLOBIN CHAIN PROD’N OXIDATION BY HEMICHROMES (REACTIVE O2) G6PD PREVENTS OXIDATION OF THE HEME GROUP DEFICIENCY – GENERATION OF REACTIVE O2 ACCUMULATES IN THE RBC DAMAGES P. FALCIPARUM

  11. VIRULENCE FACTORS RUPTURE OF SCHIZONTS RELEASE OF MEROZOITES: MONOCYTES – TNF (PYROGENIC) OTHER CYTOKINES GLYCOSYLPHOSPHATIDYL INOSITOL (GPI) KNOBS – CYTOADHESION(PfEMP) HISTIDINE RICH PROTEIN (HRP)

  12. MULTI-ORGAN INVOLVEMENT GASTRO-INTESTINAL DIARRHEA, ABD PAIN, NAUSEA, VOMITING, ANOREXIA RESPIRATORY DYSPNEA NON PRODUCTIVE COUGH

  13. FEVER PERIODICITY COINCIDES WITH RUPTURE OF SCHIZONTS INITIAL INFECTION – ASYNCHRONOUS AFTER 5- 7 D - SYNCHRONOUS PF – EVERY 40 HOURS PV & PO - EVERY 48 HOURS PM - EVERY 72 HOURS

  14. PATHO-PHYSIOLOGY DESTRUCTION OF RED BLOOD CELL (INFECTED/ UNINFECTED) PRODUCTION OF CYTOKINES - TUMOR NECROTIC FACTOR (TNF) FEVER, HYPOGLYCEMIA, ARDS SEQUESTRATION IN DEEP VASCULATURE OF INTERNAL ORGANS (RBC RECEPTORS) - INTRACELLULAR ADHESION - VASCULAR ADHESION

  15. HEMATOLOGIC CHANGES ANEMIA LEUKOPENIA THROMBOCYTOPENIA SUPPRESSED HEMATOPOIESIS RETICULOCYTES REDUCED SERUM IRON DEFECTIVE BLOOD CELL MATURATION

  16. PATHO-PHYSIOLOGYSEVERE MALARIA HYPOGLYCEMIA LOW SERUM SODIUM MALABSORPTION (FATS, XYLOSE, VIT B 12 PULMONARY EDEMA CNS DYSFUNCTION ( COMA) ELEVATED BUN, CREATININE, PROTEINURIA

  17. MALARIA OCCURS IN TROPICAL/ SUBTROPICAL COUNTRIES 300-500 M CASES ANNUALLY 1.5.-2.7 M DEATHS 10 LEADING CAUSES OF MORTALITY

  18. MALARIA FIRST FEW DAYS: STEADY LOW GRADE FEVER HEADACHE PHOTOPHOBIA MYALGIA ANOREXIA NAUSEA/ VOMITING

  19. REGULAR CYCLE CLASSIC: CHILLS FEVER SWEATING SPLENOMEGALY ANEMIA JAUNDICE

  20. CAUSES OF ANEMIA HEMOLYSIS SPENIC REMOVAL OF RBC FROM CIRCULATION AUTO-IMMUNE LYSIS DECRASED INCORPORATION OF IRON INTO HEME BONE MARROW DEPRESSION

  21. MALARIA - PHILIPPINES 65-70% P. FALCIPARUM – MALIGNANT 30% P. VIVAX – BENIGN TERTIAN 1% P. MALARIAE - QUARTAN

  22. FALCIPARUM MALARIA INVADES ALL AGES OF RBC SEQUESTRATION IN INTERNALORGANS ISCHEMIA LIVER – ABDOMINAL PAINS JAUNDICE LUNGS – PULMONARY EDEMA KIDNEYS - BLACKWATER FEVER- HEMOGLOBINURIA CEREBRAL INVOLVEMENT

  23. COMPLICATED COMA CONVULSIONS HYPOGLYCEMIA ACIDOSIS RESPIRATORY DISTRESS ALGID (CIRCULATORY COLLAPSE, SHOCK & SEPTICEMIA) HYPER-PARASITEMIA

  24. CEREBRAL MALARIA

  25. VIVAX MALARIA LESS SEVERE RELAPSES OCCUR AFTER WEEKS OR MONTHS INVADES ONLY RETICULOCYTES LOW ALBUMIN/ ELEVATED GLOBULIN INCREASED SERUM POTASSIUM

  26. MALARIAE MALARIA INVADES OLDER RBC LONGER INCUBATION PERIOD NEPHROTIC SYNDROME – DEPOSITION OF IMMUNE COMPLEXES LATENT INFECTION FOR MANY YEARS

  27. WHO ARE AT RISK? THOSE IN ENDEMIC PLACES CHILDREN PREGNANT WOMEN SPONTANEOUS ABORTION CONGENITAL INFECTIONS LOW BIRTH WEIGHT PRE-TERM DELIVERY PERI-NATAL DEATH TRAVELERS BLOOD RECIPIENTS- TRANSFUSION

  28. PHILIPPINES 14.8% AT RISK SOLDIERS FARMERS INDIGENOUS CULTURAL GROUPS MINERS FOREST WORKERS 65/ 79 PROVINCES 8TH LEADING CAUSE OF MORBIDITY

  29. SOLDIERS/ FORESTERSSCOUT RANGERSLOGGERS

  30. MALARIA FREE AKLAN GUIMARAS BILIRAN ILOILO BOHOL LEYTE CAMIGUIN LEYTE DEL SUR CAPIZ N/ SAMAR CATANDUANES SIQUIJOR CEBU

  31. HIGHLY ENDEMIC PLACES PALAWAN KALINGA-APAYAO IFUGAO AGUSAN DEL SUR

  32. DIAGNOSIS CLINICAL – MIMIC DISEASE GASTROENTERITIS PNEUMONIA MENINGITIS HEPATITIS ENCEPHALITIS DENGUE TYPHOID TRAVEL Hx

  33. LABORATORY Dx BLOOD SMEARS THICK/ THIN STAIN WITH WRIGHT’S OR GIEMSA FLOURESCENT STAINING (QBC) SEROLOGY: ANTIBODY DETECTION: IFAT ELISA ANTIGEN DETECTION : RAPID DIAGNOSTIC TESTS (RDT’S) HRP II LDH PCR
