Malaria and dysentery are both diseases caused by protista. Malaria is caused by the plasmodium parasite and transmitted via anopheles mosquitoes. It occurs most commonly in sub-Saharan Africa. Symptoms include fever, chills, and vomiting, and if untreated can cause serious illness or death. Dysentery is caused by the entamoeba histolytica parasite and transmitted via contaminated water or food. Symptoms include abdominal pain, diarrhea with blood or mucus, and fatigue. Both diseases are treated with drugs like antimalarials or antibiotics.

Protozoa
Protozoa are a diverse group of unicellular eukaryotic organisms that were coined in 1818. They are eukaryotic with a nucleus and organelles, rely on their environment for nutrition, and do not have chlorophyll. Protozoa include flagellates, ciliates, and amoebae that move using flagella, cilia, or pseudopods respectively. As components of micro and meiofauna, protozoa are an important food source and play a role in transferring production between trophic levels as both herbivores and consumers. Examples of protozoa discussed include the amoeba, trypanosoma, plasmodium, paramecium, and
Life cycles of insects
The document discusses the life cycles of several insects:
- The grasshopper's life cycle has 3 stages - egg, nymph, and adult. The nymph hatches from the egg and grows wings as an adult over 4-7 weeks.
- The mosquito's life cycle has 4 stages - egg, larva, pupa, and adult. The larva hatches and grows in water before becoming a pupa then adult.
- The cockroach's life cycle mirrors the grasshopper's with 3 stages - egg, nymph, and adult. The nymph hatches and molts its skin 8 times before becoming an adult.
- The housefly's life cycle also has 4

MICRO Chap 4 Part 1 Human and Microbial Interactions
This document discusses human and microbial interactions, focusing on normal flora and conditions that determine the nature of flora. It describes how normal flora varies across body sites and provides benefits like producing nutrients, while opportunistic infections can occur when defenses are compromised, allowing normally harmless flora to cause infection. Factors like pathogen virulence and host health influence disease development and outcomes of pathogen encounters.
Protozoa
Protozoans are unicellular eukaryotes that lack cell walls and motility is provided by cilia, flagella, or pseudopodia. They ingest food and can reproduce asexually through binary fission or budding or sexually through conjugation or gamete fusion. Plasmodium, a protozoan parasite, causes the disease malaria in humans. It has a complex life cycle alternating between mosquito and human hosts. In humans it evades the immune system by hiding in the liver and red blood cells, where it consumes hemoglobin and reproduces asexually.
Fleas by jalees mirza
Fleas are small, wingless insects that feed on the blood of mammals and birds. They have mouthparts adapted for piercing skin and sucking blood. Fleas go through four life stages: egg, larva, pupa, and adult. Common flea species include the cat flea, dog flea, human flea, and various rat fleas.

Paramecium locomotion
Paramecium use two types of locomotion - ciliary movement and metabolic locomotion. Ciliary movement involves the synchronized and metachronous beating of cilia to propel the organism in a spiral path. Metabolic locomotion involves changes in body shape through protoplasmic movement. Paramecium feed by sweeping bacteria and algae into the oral groove using cilia, which then pass through the cytostome and into food vacuoles for digestion. Undigested particles are egested through the cytopyge. Paramecium regulate water content through two contractile vacuoles that collect and expel excess water taken in by osmosis.

toxoplasma gondii
Toxoplasma gondii is a cosmopolitan parasite that infects a wide range of animals including birds and humans. It has two infectious forms, tachyzoites and bradyzoites. Tachyzoites rapidly proliferate in phagocytic cells while bradyzoites form cysts in tissues like the brain. Cats are the definitive host and shed infectious oocysts in their feces which can infect intermediate hosts through ingestion. In humans, infection usually occurs by ingesting oocysts, tissue cysts, or congenitally from mother to fetus. While most infections are asymptomatic, it can cause mild flu-like symptoms or severe toxoplasmic encephalitis in immunocomp
Arthropods
Arthropods are the most diverse group of animals, with over 1 million known species. They have bilateral symmetry, an exoskeleton made of chitin, jointed appendages, and segmented bodies. Arthropods are classified into five main groups - trilobites, myriapods, chelicerates, crustaceans, and insects - based on body segments, number of legs, and other features. Myriapods have many leg pairs, chelicerates have specialized mouthparts, crustaceans live in water and land and have five leg pairs, and insects are the largest group and mostly live on land with three leg pairs.
Acanthocephala .pptx
Dayalbagh Educational Institute G.D. / Seminar presentation Acanthocephala Presented by- Sonam kumari
Acanthocephala are parasitic worms with a spiny proboscis that infect the intestines of animals. They have complex life cycles involving an invertebrate host and a vertebrate host. Over 1420 species have been described. They absorb nutrients through their body wall and have no digestive or respiratory systems. Common parasites of wildlife and domestic animals, some species can accidentally infect humans. Control in fish farms involves medicated feed containing anti-parasitic compounds.
Mammals
Mammals are warm-blooded vertebrate animals that have hair, mammary glands to feed their young, and a four-chambered heart. There are over 4000 mammal species that are classified into three main groups: monotremes, marsupials, and placentals. Monotremes lay eggs while marsupials give birth to tiny young that crawl into their mother's pouch. Placental mammals carry their young to full development within the uterus. Some key mammalian characteristics include hair, well-developed brains, teeth adapted for chewing, and a diaphragm that aids breathing.

Hitler Project
Adolf Hitler was born in 1889 in Austria and showed early academic promise but was rejected from art school twice. He joined the German Workers' Party in 1919 and helped transform it into the Nazi Party. As leader he rose to power in 1933 becoming Chancellor of Germany and established a fascist dictatorship. He abolished democracy and made the Nazi Party the only legal party. Hitler pursued aggressive expansionist policies, invading countries in Europe and sparking World War II. He committed suicide in 1945 as Allied forces advanced on Berlin and Germany surrendered, ending his regime.

Malaria
Malaria is caused by a single-celled parasite called Plasmodium that is spread through the bites of infected Anopheles mosquitoes. The parasite invades and destroys red blood cells, causing symptoms like fever, chills, and headaches. In severe cases of cerebral malaria, the parasite can cause brain damage or death. While most common in Africa due to climate and living conditions, malaria is also found in parts of Asia, Latin America, and the Middle East. Treatment focuses on killing the parasite, usually through antimalarial drugs like chloroquine.

The document discusses the history, causes, transmission, symptoms, treatment and prevention of malaria. It notes that malaria is caused by a parasite transmitted through mosquito bites. Key events included the discovery of the malaria parasite in 1880 and the identification of mosquitoes as the transmission vector in the early 1900s. Malaria remains a major public health problem, especially in sub-Saharan Africa where it is responsible for significant illness, death and economic losses each year.
Malaria
Malaria is a disease caused by Plasmodium parasites and transmitted via mosquito bites. It is a major public health problem in tropical areas, causing around 500 million cases and 1 million deaths annually. Young children and pregnant women are most vulnerable. The parasite has a complex life cycle alternating between human and mosquito hosts. Symptoms occur during the parasite's blood stage and include fever, chills and anemia. Host and parasite factors determine disease severity, from asymptomatic to severe or fatal cases.
Malaria
Malaria is a mosquito-borne infectious disease caused by parasitic protozoans of the genus Plasmodium. It is transmitted via the bite of an infected female Anopheles mosquito, which introduces the parasites into a person's bloodstream. The parasites travel to the liver to mature and reproduce before infecting red blood cells. Common symptoms include fever, headache, and in severe cases coma or death. There are five species that can infect humans but P. falciparum and P. vivax cause the majority of malaria cases and deaths worldwide, especially in sub-Saharan Africa and tropical regions.
Malaria
Malaria is a mosquito-borne parasitic disease caused by Plasmodium parasites. It affects over 100 tropical and subtropical countries and causes hundreds of millions of cases and millions of deaths annually. The disease is transmitted via the bites of infected female Anopheles mosquitoes. It has a complex life cycle involving sexual reproduction in the mosquito and asexual reproduction in human hosts. Symptoms vary depending on the Plasmodium species but can include fever, chills, flu-like illness, and in severe cases organ damage or death. Diagnosis is via blood smear microscopy or rapid antigen tests. Prevention focuses on mosquito control and use of insecticide-treated bed nets, while treatment involves antimalarial medications

Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected Anopheles mosquitoes. The parasites multiply in the liver and infect red blood cells. Symptoms include fever, chills, and flu-like illness. Malaria occurs commonly in Africa, Asia, South and Central America, and can be prevented by avoiding bites from infected mosquitoes and treated with antimalarial drugs.

- Pathogens are organisms that cause disease and include viruses, bacteria, fungi, protozoa, and parasites.
- Bacteria and fungi are important in ecosystems but some species can cause illness in humans. Viruses and parasites rely on living hosts.
- Common diseases result from pathogens like influenza and SARS-CoV-2 viruses, malaria protozoa, and roundworm infections. Those with weak immune systems face higher risks. Prevention focuses on hygiene, sanitation, and treatment of infections.
Why do we fall ill
Disease is defined as an abnormal condition that affects the structure or function of an organism. Malaria is a mosquito-borne disease caused by Plasmodium parasites. It causes flu-like symptoms like fever and fatigue. Severe malaria from P. falciparum can cause complications like seizures, coma, or death if not treated properly. Malaria is treated with antimalarial drugs and prevented through mosquito control measures like insecticide-treated nets and indoor spraying.
Amoebiasis
This document discusses amoebiasis, a protozoan disease caused by Entamoeba histolytica. Protozoa are single-celled parasites that can infect humans and cause disease. Amoebiasis is transmitted through the fecal-oral route by ingesting the cyst form of E. histolytica found in feces. Symptoms include abdominal cramps, diarrhea with mucus or blood, fatigue, gas, and rectal pain. Treatment involves anti-amoebic drugs like tinidazole and metronidazole to treat intestinal infections and prevent further spread through proper hygiene and sanitation.

The document provides an introduction to parasitology and the diagnosis of parasitic diseases. It notes that parasites infect over a billion people worldwide and cause significant suffering and death. It then summarizes key data on the global burden of major parasitic infections like malaria, schistosomiasis, lymphatic filariasis, and Chagas disease. The document goes on to define important parasitology terms and provide taxonomical classifications and life cycle descriptions of important protozoan and helminth parasites, including Plasmodium, Giardia, hookworms, Taenia tapeworms, and Schistosoma. It also describes the epidemiology, symptoms, pathology, diagnosis and treatment of select parasitic diseases.
communicable Diseases
The document provides information about various communicable diseases including Malaria, AIDS, Typhoid, Elephantiasis, Tuberculosis, and Cholera. For each disease, it discusses the causes, symptoms, and methods of prevention. Malaria is spread by mosquitoes and causes shaking chills, fever, and anemia. AIDS is caused by the HIV virus and left untreated can lead to death. Typhoid is caused by Salmonella bacteria and can cause fever, abdominal pain, and rash. Elephantiasis is caused by filarial worms spread through mosquitoes and causes thickened skin. Tuberculosis is a widespread problem that causes cough, weight loss, and fatigue. Cholera, caused

The document discusses several common human diseases including typhoid, pneumonia, common cold, malaria, amoebiasis, ascariasis, filariasis, and ringworms. It provides details on the causative agents, transmission, symptoms, and treatment for each disease. Key facts include that typhoid is caused by Salmonella typhi bacteria through contaminated food or water, malaria is caused by Plasmodium parasites transmitted via Anopheles mosquitoes, and ringworms are fungal infections spread through direct contact.
Lecture 11 malaria
Malaria is a serious disease caused by parasites transmitted through mosquito bites. It causes flu-like symptoms including fever, shaking chills, and headaches. The most deadly form is caused by Plasmodium falciparum. Malaria is typically found in warm, tropical climates and those at highest risk are residents of and travelers to malaria-endemic regions. Prevention methods include using insect repellent, sleeping under treated bed nets, and taking anti-malarial drugs. Currently there is no vaccine for malaria.
Malaria
Malaria is a parasitic disease spread by mosquito bites that causes high fevers, shaking chills, and flu-like symptoms. It is caused by a parasite that travels through the bloodstream to the liver and then infects red blood cells, bursting from the cells and infecting others. Malaria can be prevented through protection from mosquito bites like bed nets and repellent, and treating with anti-malarial drugs.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Recently uploaded (20)

Diseases caused by protista
- 1. Diseases caused by protista Malaria / Dysentery
- 2. Malaria • Malaria is a disease caused by a parasite called plasmodium , a sporotozoan (animal like protist). It was a major case of deaths during all human existence but took the state a full scale epidemic during the XX century.
- 3. Infection Only anopheles mosquitoes are the know vectors for transmissing malaria .But for the mosquito must have ben infected form a previous blood meal taken on a infected human.
- 4. Life cycle When a plasmodium enters a human system it travels to the liver cells through the blood vessels . There they transform into merozoites that after develop into gametocytes which are the precursors of gametes . When another mosquito bites this human new spores migrate .
- 5. Contagious or not ? Until now the only way known for the transmission of malaria is by one kind mosquito. So we can’t call it contagious or infectious .
- 6. Where does malaria occur Malaria commonly occurs in Africa ,Asia ,South America ,Central America ,Southern Mexico and Caribbean .But the most occurrences happen in Sub-Saharan Africa .These countries have a big amount of plasmodium falciparum which is the most dangerous of the four species.
- 7. Symptoms Symptoms of malaria may include fever ,chills ,vomiting ,couch ,stomach pain , muscle aches ,weakness . If infected with the most severe form of malaria and if left untreated it can cause serious illnesses like seizures ,mental confusion ,kidney failure ,coma and death .
- 8. Treatment Malaria is treated with a class of drugs called anti malarial. antimalarial drugs are designed to attack the parasites that cause malaria ,preventing them from spreading while also killing them off so they can’t continue causing infection .
- 9. Dysentery Dysentery is caused by Entamoeba histolytica which is a parasitic protozoan . Its main targets are humans and other primates.
- 10. Infection Dysentery can only and only enter in the human system through oral input . It can be rendered possible when a person drinks turbid water. Also people who consume infected feces but that’s a very rare case and the persons in words had mental disorders .
- 11. Life cycle
- 12. Symptoms Symptoms of amoebic dysentery include: • abdominal pain • fever and chills • nausea and vomiting • watery diarrhea, which can contain blood, mucus or pus • painful passing of stools • fatigue • intermittent constipation.
- 13. What does it cause ? Entamoeba histolytica that, among other things, can cause severe diarrhea with blood. But it may cause milder chronic symptoms of: frequent loose stools , abdominal pain
- 14. Treatment Treatments for dysentery Rehydration therapy Antibiotics and amoebicidal drugs Antirheumatic drug Ridaura
