General Characters of Phylum Protozoa

General Characters of Phylum Protozoa

General Characters of Phylum Protozoa Some of the characteristics are: There are about 50,000 known species of Phylum Protozoa. Protozoans exhibit mainly two forms of life; free-living (aquatic, fresh water, sea water) and parasitic (ectoparasites or endoparasites). They are also commensal in habitat. They are small, usually microscopic, not visualize without a microscope. They are … Read moreGeneral Characters of Phylum Protozoa

Classification of Phylum Protozoa

Classification of Phylum Protozoa Phylum protozoa is a large and varied group and possess a complication in its classification. The conventional scheme followed by Hyman (1940), Hickman (1961) and Storer (1965) etc. recognizes two subphyla on the basis of organs of locomotion and 5 classes as follows: Sub Phylum A: Plasmodroma Locomotory organelles are flagella, … Read moreClassification of Phylum Protozoa

Lower and Higher Invertebrates with their differences

Lower and Higher Invertebrates

Lower and Higher Invertebrates with their differences The invertebrates are usually classified as Lower Invertebrates and Higher Invertebrates. Lower Invertebrates The lower invertebrates are simple in body organization. They are generally small in size. These are thought to have originated in the main lines of evolution, near the base of the phylogenetic tree of Animal … Read moreLower and Higher Invertebrates with their differences

Differences between Invertebrates and Vertebrates

Differences between Invertebrates and Vertebrates

Differences between Invertebrates and Vertebrates The animal kingdom has been divided into two major groups: Invertebrates (Non-Chordates) and Vertebrates (Chordates). Invertebrates are those that do not possess a vertebral column or backbone while Vertebrates are those where vertebral column or backbone is present. These two groups have some differences as follows: S.N. Characteristics Invertebrates (Non-Chordates) … Read moreDifferences between Invertebrates and Vertebrates

Carbohydrates

Carbohydrates

Carbohydrates are molecules that contain carbon, hydrogen, and oxygen. There are twice as many hydrogen atoms as carbon or oxygen atoms. The general formula for a carbohydrate can be written as Cx(H2O)y. They act as the source of energy (e.g. glucose), as a store of energy (e.g. starch and glycogen) and as structural units (e.g. … Read moreCarbohydrates

Staphylococcus aureus- Lab Diagnosis, Treatment, Prevention

Staphylococcus aureus- Lab Diagnosis, Treatment, Prevention

Staphylococcus aureus are catalase-positive, gram-positive cocci which frequently colonize the skin and mucosa of humans and animals. However, it is a highly successful opportunistic pathogen and thus involved in various diseases including toxin-mediated diseases (food poisoning, toxic shock syndrome, scalded skin syndrome), pyogenic diseases (impetigo, folliculitis, furuncles, carbuncles, wound infections), and other systemic diseases. The … Read moreStaphylococcus aureus- Lab Diagnosis, Treatment, Prevention
