What is Zooplankton? Characteristics of Zooplanktons Zooplankton, a term originating from the Greek words “zoon” (meaning animals) and “planktos” (meaning wanderers or drifters), are heterotrophic organisms that inhabit aquatic environments. These entities exhibit several distinct characteristics: In summary, zooplankton are integral components of aquatic ecosystems, influencing nutrient dynamics, food web structures, and even disease propagation. … Read more

Classification of Sporozoa Characteristics of Sporozoa Motility of Sporozoa Feeding of Sporozoa Types of Spores Sporozoans, a group of parasitic protozoa, can be classified into four categories based … Read more
Human African trypanosomiasis, also known as sleeping sickness, is a parasitic disease transmitted by vectors and caused by Trypanosoma-genus protozoa. There are three subspecies of the parasite: Trypanosoma brucei gambiense, T. brucei rhodesiense, and T. brucei brucei. The latter subspecies is not human-pathogenic. These subspecies are morphologically indistinguishable. T. b. gambiense is located in western … Read more
What is Gastrointestinal Amebiasis? Characteristics of Entamoeba histolytica Entamoeba histolytica is a pseudopod-forming anaerobic protozoan parasite that is responsible for causing amebiasis in humans. Here are some key characteristics of Entamoeba histolytica: Life Cycle of E. histolytica Gene Structure and Organization Cell Biology and Biochemistry Sources of contamination of Amebiasis Amebiasis can be sourced from … Read more
Fascioliasis is an infectious disease caused by Fasciola parasites, which are flatworms referred to as liver flukes. The adult (mature) flukes are found in the bile ducts and liver of infected people and animals, such as sheep and cattle. In general, fascioliasis is more common in livestock and other animals than in people.
Lymphatic filariasis is a parasitic disease caused by three microscopic, thread-like worms, called Wuchereria bancrofti, Brugia malayi and Brugia timori. These worms infect the lymphatic system and cause Lymphatic filariasis. The adult worm can be found in the human lymph system, this system helps to maintain the body’s fluid balance and fights against infections.
The size and shape of protozoa vary based on the types of species. For example, the causative agent of Kala azar, Leishmania donovani has a size range of 1 to 4 micrometers in length, while the Amoeba proteus is 600 micrometers or more in size. Some members of ciliates can reach 2,000 micrometers or 2mm.
Leishmaniasis are flagellated protists that cause a group of several human diseases collectively called leishmaniasis. Leishmaniasis also known as kala azar. There are different types of leishmaniasis such as cutaneous (skin associated ulcers that heal), diffuse cutaneous (disseminated and chronic skin lesions), mucocutaneous (ulcers of the skin, mouth, nose, and throat), and visceral (affecting liver, … Read more
What is Paramecium? Definition of Paramecium Paramecium is a microscopic, single-celled organism with hair-like structures called cilia, found in various aquatic environments, often studied for its role as a model organism in biological research. Paramecium Scientific classification Paramecium is divided into this following phylum and subphylum; Domain: Eukaryota Clade: SAR Infrakingdom: Alveolata Phylum: Ciliophora Class: … Read more

Protozoa don’t have any cell walls, instead they contain pellicle. The structure of Protozoa is similar to the eukaryotic cells. Some examples of protozoa are Trypanosoma, Trichonympha, Plasmodium, Paramecium. Now, Protozoa is a strictly descriptive term, they are no longer recognized as a formal group in current biological classification systems. Protozoa are ubiquitous, which means … Read more
