SCHOOL OF MEDICINE BMM 3101: PARASITOLOGY AND ENTOMOLOGY C.A.T 1 (50 marks) --- Q1. Define the following terminologies (3 marks) i. Zoophilic Vectors that prefer feeding on animal blood rather than human blood. ii. Endophagic Vectors that prefer feeding indoors (inside buildings/houses). iii. Fomite Non-living objects capable of transmitting infectious pathogens from one host to another. --- Q2. With examples, outline five (5) medical importances of arthropods (10 marks) 1. Biological vectors of disease Transmit pathogens that multiply/develop in them Example: Anopheles mosquitoes transmit malaria; tsetse flies transmit sleeping sickness 2. Mechanical vectors Carry pathogens on body parts without pathogen development Example: Houseflies and cockroaches transmit cholera, typhoid 3. Direct causative agents Cause disease through infestation Example: Scabies mite ( Sarcoptes scabiei ), head lice 4. Venomous effects Cause injury through bites/stings Example: Scorpions, spiders, bees cause envenomation 5. Nuisance and allergic reactions Cause irritation and hypersensitivity Example: Mosquito bites, bed bugs, dust mites trigger allergies --- Q3. Using an illustration, discuss the life cycle of a three-host tick (15 marks) Three-Host Tick Life Cycle (e.g., Rhipicephalus appendiculatus ) Stages: Eggs → Laid on ground by engorged female (2,000-20,000 eggs) Larvae (6-legged) → Hatch, climb vegetation, attach to HOST 1 (small mammals/birds), feed 3-7 days, drop off, molt to nymph Nymph (8-legged) → Climb vegetation, attach to HOST 2 (medium mammals), feed 4-7 days, drop off, molt to adult Adult (8-legged) → Climb vegetation, attach to HOST 3 (large mammals/cattle), mate on host, female feeds 7-14 days, drops off, lays eggs, dies Key feature: Each stage feeds on a different host and drops to ground to molt. Duration: Complete cycle takes 6 months to 3 years depending on conditions. --- Parasitology Tables - { margin: 0; padding: 0; box-sizing: border-box; } body { font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif; background: white; padding: 0; min-height: 100vh; } .container { max-width: 100%; margin: 0 auto; background: white; padding: 20px; border-radius: 0; box-shadow: none; } .header { text-align: center; margin-bottom: 30px; border-bottom: 3px solid #667eea; padding-bottom: 15px; } .header h1 { color: #667eea; font-size: 1.5em; margin-bottom: 8px; } .header h2 { color: #764ba2; font-size: 1em; font-weight: normal; } .table-card { background: white; border: 2px solid #667eea; border-radius: 12px; margin-bottom: 20px; overflow: hidden; box-shadow: 0 4px 12px rgba(0,0,0,0.1); cursor: pointer; transition: transform 0.2s, box-shadow 0.2s; } .table-card:active { transform: scale(0.98); } .table-card-header { background: linear-gradient(135deg, #667eea 0%, #764ba2 100%); color: white; padding: 15px; font-size: 1.1em; font-weight: bold; display: flex; justify-content: space-between; align-items: center; } .tap-icon { font-size: 1.3em; animation: pulse 2s infinite; } @keyframes pulse { 0%, 100% { transform: scale(1); } 50% { transform: scale(1.1); } } .table-preview { padding: 15px; color: #666; font-size: 0.95em; text-align: center; } / Modal styles / .modal { display: none; position: fixed; z-index: 1000; left: 0; top: 0; width: 100%; height: 100%; background-color: rgba(0,0,0,0.9); overflow: auto; } .modal.active { display: flex; align-items: center; justify-content: center; } .modal-content { position: relative; margin: auto; padding: 0; width: 95%; max-width: 1200px; max-height: 90vh; overflow: auto; background: white; border-radius: 10px; } .close { position: sticky; top: 0; right: 0; color: white; background: #764ba2; font-size: 35px; font-weight: bold; padding: 10px 20px; cursor: pointer; z-index: 1001; text-align: right; border-radius: 10px 10px 0 0; } .close:hover { background: #667eea; } .modal-table-container { padding: 20px; } .modal-title { background: linear-gradient(135deg, #667eea 0%, #764ba2 100%); color: white; padding: 15px; font-size: 1.2em; font-weight: bold; margin-bottom: 20px; border-radius: 8px; } table { width: 100%; border-collapse: collapse; margin-bottom: 20px; font-size: 0.9em; } th { background: linear-gradient(135deg, #764ba2 0%, #667eea 100%); color: white; padding: 12px 8px; text-align: left; font-weight: 600; font-size: 0.85em; } td { padding: 10px 8px; border-bottom: 1px solid #e0e0e0; color: #333; } tr:nth-child(even) { background-color: #fafafa; } .species-list { background: #f0f4ff; padding: 15px; border-radius: 8px; margin-top: 15px; border-left: 4px solid #667eea; } .species-list h4 { color: #667eea; margin-bottom: 10px; } .species-list ul { list-style: none; padding-left: 0; } .species-list li { padding: 5px 0; color: #555; } .species-list li:before { content: "→ "; color: #764ba2; font-weight: bold; } em { color: #764ba2; font-style: italic; } @media (max-width: 768px) { table { font-size: 0.75em; } th, td { padding: 8px 4px; } .modal-content { width: 98%; } } Insectic
