Classification of Parasites BLY 459 First Lab Test (October 10, 2010)
Classification of Parasites BLY 459 First Lab Test (October 10, 2010) If a taxonomic name is not in bold type, you will not be held responsible for it on the lab exam. Terms and common names that may be asked are also listed. I have attempted to be consistent with the taxonomic schemes in your text as well as to list all slides and live specimens that were displayed. In addition to highlighted taxa, be familiar with, material in lab handouts (especially proper nomenclature), lab display sheets, as well as material presented in lecture. Questions about vectors and locations within hosts will be asked. Be able to recognize healthy from infected tissue.

Ascaris Lumbricoides, Roundworm, Causative Agent Of
http://www.MetaPathogen.com: Human roundworm, Ascaris lumbricoides ● Ascaris lumbricoides taxonomy ● Brief facts ● Developmental stages ● Treatment ● References Ascaris lumbricoides taxonomy cellular organisms - Eukaryota - Fungi/Metazoa group - Metazoa - Eumetazoa - Bilateria - Pseudocoelomata - Nematoda - Chromadorea - Ascaridida - Ascaridoidea - Ascarididae - Ascaris - Ascaris lumbricoides Brief facts ● Together with human hookworms (Ancylostoma duodenale and Necator americanus also described at MetaPathogen) and whipworms (Trichuris trichiura), Ascaris lumbricoides (human roundworms) belong to a group of so-called soil-transmitted helminths that represent one of the world's most important causes of physical and intellectual growth retardation. ● Today, ascariasis is among the most important tropical diseases in humans with more than billion infected people world-wide. Ascariasis is mostly seen in tropical and subtropical countries because of warm and humid conditions that facilitate development and survival of eggs. The majority of infections occur in Asia (up to 73%), followed by Africa (~12%) and Latin America (~8%). ● Ascaris lumbricoides is one of six worms listed and named by Linnaeus. Its name has remained unchanged up to date. ● Ascariasis is an ancient infection, and A. lumbricoides have been found in human remains from Peru dating as early as 2277 BC. There are records of A. lumbricoides in Egyptian mummy dating from 1938 to 1600 BC. Despite of long history of awareness and scientific observations, the parasite's life cycle in humans, including the migration of the larval stages around the body, was discovered only in 1922 by a Japanese pediatrician, Shimesu Koino. ● Unlike the hookworm, whose third-stage (L3) larvae actively penetrate skin, A. lumbricoides (as well as T. trichiura) is transmitted passively within the eggs after being swallowed by the host as a result of fecal contamination. -

Phylum-wide nematode phylogenetic hypotheses have mainly been based on nuclear rDNA sequences, but more recently complete mitochondrial (mtDNA) gene sequences have provided another source of molecular information to evaluate relationships. Although there is much agreement between nuclear rDNA and mtDNA phylogenies, relationships among certain major clades are different. In this study we report that mtDNA sequences do not support the monophyly of Ascaridida, Oxyurida and Spirurida (clade III) in contrast to results for nuclear rDNA. Results from mtDNA genomes show promise as an additional independently evolving genome for developing phylogenetic hypotheses for nematodes, although substantially increased taxon sampling is needed for enhanced comparative value with nuclear rDNA. -

EENY-530 Entomopathogenic Nematodes (Nematoda: Rhabditida: families Steinernematidae and Heterorhabditidae) 1 Nastaran Tofangsazi, Steven P. Arthurs, and Robin M. Giblin-Davis2 Introduction Entomopathogenic nematodes are soft bodied, non- segmented roundworms that are obligate or sometimes facultative parasites of insects. Entomopathogenic nema- todes occur naturally in soil environments and locate their host in response to carbon dioxide, vibration, and other chemical cues (Kaya and Gaugler 1993). Species in two families (Heterorhabditidae and Steinernematidae) have been effectively used as biological insecticides in pest man- agement programs (Grewal et al. 2005). Entomopathogenic nematodes fit nicely into integrated pest management, or IPM, programs because they are considered nontoxic to Figure 1. Infective juvenile stages of Steinernema carpocapsae clearly humans, relatively specific to their target pest(s), and can showing protective sheath formed by retaining the second stage be applied with standard pesticide equipment (Shapiro-Ilan cuticle. et al. 2006). Entomopathogenic nematodes have been Credits: James Kerrigan, UF/IFAS exempted from the US Environmental Protection Agency Life Cycle (EPA) pesticide registration.

The juvenile stage penetrates the host insect via the spiracles, mouth, anus, or in some species through intersegmental membranes of the cuticle, and then enters into the hemocoel (Bedding and Molyneux 1982). Both Heterorhabditis and Steinernema are mutualistically associated with bacteria of the genera Photorhabdus and Xenorhabdus, respectively (Ferreira and 1.

ZooKeys 574: 43–55. doi: 10.3897/zookeys.574.7222 Abstract The dataset of free-living marine nematodes of San Antonio Bay is based on sediment samples collected in February 2009 during doctoral theses funded by CONICET grants. A total of 36 samples has been taken at three locations in the San Antonio Bay, Santa Cruz Province, Argentina on the coastal littoral at three tidal levels. This presents a unique and important collection for benthic biodiversity assessment of Patagonian nematodes as this area remains one of the least known regions. -
