EXCAVATA: Excavata (eks-ka-VA-tuh) is formed from two Latin words that mean from (ex) and cavity (cavatum).The reference is to a depression in the cell called the excavate, which may be associated with one of the flagella and may function in feeding. Diplomonads exist in anaerobic environments and use alternative pathways, such as glycolysis, to generate e… Mitochondrial remnant organelles, called mitosomes, have since been identified in diplomonads, but these mitosomes are essentially nonfunctional. The mammalian intestinal parasite Giardia lamblia, visualized here using scanning electron microscopy, is a waterborne protist that causes severe diarrhea when ingested. The mitochondrial Ca2+ uptake in trypanosomatids, which belong to the eukaryotic supergroup Excavata, shares biochemical characteristics with that of animals, which, together with fungi, belong to the supergroup Opisthokonta. Many of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove “excavated” from one side. Recent studies have revealed unique characteristics of this machinery, particularly in the eukaryotic supergroup Excavata. Members of the third, and much smaller, group (traditionally known as acrasids but more appropriately referred to as sorocarpic amoebae) belong to the supergroup Excavata. In the dark, the chloroplasts of Euglena shrink up and temporarily cease functioning, and the cells instead take up organic nutrients from their environment. Whereas men rarely exhibit symptoms during an infection with this protist, infected women may become more susceptible to secondary infection with human immunodeficiency virus (HIV) and may be more likely to develop cervical cancer. Characteristics Euglenozoans Kinetoplastids Ex. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. It was first suggested by Simpson and Patterson in 1999 and introduced by Thomas Cavalier-Smith in 2002 as a formal taxon. T. brucei is common in central Africa and is the causative agent of African sleeping sickness, a disease associated with severe chronic fatigue and coma; it can be fatal if left untreated. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. T. brucei is common in central Africa and is the causative agent of African sleeping sickness, a disease associated with severe chronic fatigue, coma, and can be fatal if left untreated. They possess characteristics of plants and animals. Clade 2 C 2. Among the Excavata are the diplomonads, which include the intestinal parasite, Giardia lamblia (Figure 1). This supergroup includes heterotrophic predators, photosynthetic species, and parasites. The Origin of Eukarya Supergroup Excavata. In parabasalids, these structures function anaerobically and are called hydrogenosomes because they produce hydrogen gas as a byproduct. Among the Excavata are the diplomonads, which include the intestinal parasite, Giardia lamblia (Figure 1). The parasite then travels to the insect salivary glands to be transmitted to another human or other mammal when the infected tsetse fly consumes another blood meal.
