Study Notes
Bee and Cow Interaction
- Bees extract nectar from flowers, which serves as food.
- Cows provide a warm liquid environment through their milk.
- Pollens are transported by bees, sticking to their bodies, aiding in the pollination process.
- Microbes in cows help break down cellulose, facilitating nutrient absorption.
Phoresis (Phoresy)
- Phoresis refers to one organism carrying another, typically where the carrier is larger.
- The smaller organism is called the phorant, while the larger is known as the host.
- Moraxella bovis, responsible for pink eye in cattle, is transmitted from one cow's eye to another via Musca autumnalis (face fly) foot pads.
WHO Top 10 Infectious Diseases
- Ascaris: 1220 million infections, 65,000 deaths, cosmopolitan distribution, transmitted orally.
- Hookworm: 740 million infections, 65,000 deaths, common in tropical regions, transmitted through skin penetration.
- Malaria: 207 million cases, 627,000 deaths, primarily in tropical regions, spread by mosquitoes.
- Whipworm: 800 million infections, no significant mortality, cosmopolitan distribution, transmitted orally.
- Amoebiasis: 50 million infections, 55,000 deaths, found in both cosmopolitan and tropical areas, oral transmission.
- Filariasis: 160 million infected, unclear mortality, prevalent in tropical regions, transmitted by mosquitoes.
- Schistosomiasis: 240 million require treatment, 200,000 deaths, tropical distribution, penetrates skin.
- Giardiasis: 280 million infections, no reported deaths, cosmopolitan distribution, transmitted orally.
- Trypanosomiasis: 30 million cases in Africa (48,000 deaths) & 8 million in America (11,000 deaths), transmitted by tsetse flies and kissing bugs, respectively.
- Leishmaniasis: 1.6 million new cases, 30,000 deaths, tropical distribution, transmitted by sand flies.
- Pinworm: 200 million infections, no mortality, common in temperate regions, transmitted orally.
- Trichomoniasis: 187 million infections, no deaths, cosmopolitan distribution, transmitted venereally.
Taxonomy Overview
- Organisms are classified into hierarchical categories:
- Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Primary kingdoms discussed include Protista and Animalia, encompassing protozoa, helminths, and arthropods.
- Arthropods fall under the phylum Arthropoda, which contains various relationships and types of symbiosis.
Symbiosis
- Symbiosis is defined as any mutual association between organisms of different species.
- Example provided: Anopheles mosquitoes act as biological vectors, transmitting malaria.
- Vectors are classified into two categories:
- Biological Vector: Ingests and develops the agent within.
- Mechanical Vector: Simply transports the agent without replication.
