Heterophyes heterophyes Introduction: Heterophyes heterophyes is a small parasitic fluke that infects humans who eat raw or undercooked fish infected with the metacercaria stage of the parasite. The adult parasite lives in the intestinal villi of humans (the definitive host). The first intermediate host of H. heterophyes ar Heterophyes heterophyes (Pathogen - Intestinal Trematode) Organism: H. heterophyes is one of the smallest trematodes to infect humans and is acquired through the ingestion of pickled or uncooked fish. The heterophyids are capable of parasitizing birds and mammals, and infection was first reported by Bilharz in 1851. Egg Adult wor ABSTRACT: Heterophyes heterophyes, agent of human heterophyiasis in the Near East, is transmit- ted in marine lagoons and saline inland waters, where the euryhaline intermediate hosts are abundant. In Egypt, mullets, the predominant second intermediate hosts, are customarily consume Of at least 10 human species of intestinal fluke in the family Heterophyidae, the three most prevalent are Heterophyes heterophyes, H. nocens, and Metagonimus yokogawai. Bilharz described the first, H. heterophyes, at the autopsy of a native of Cairo. 50 These are the smallest of the human flukes. They measure 1-2 mm in length, are oval to pear-shaped, and have spiny integuments Heterophyes Infection [Heterophyiasis] Heterophyes Infection is an endemic infectious disease caused by the trematode known as Heterophyes heterophyes, a very small intestinal flatworm or fluke. It is common in Far East, Middle East, and Egypt

Adults of Heterophyes heterophyes are minute flukes, measuring 1-2 mm in length. The tests are large and paired, and are situated near a small ovary. The surface of the worm is covered with minute spines.

  1. ated raw or undercooked fish. Symptoms typically range from asymptomatic to intermittent abdo
  2. Heterophyes flukes are morphologically distinguished from other heterophyids, including Heterophyopsis, Metagonimus, Pygidiopsis, Centrocestus, Stellantchasmus, Haplorchis, Procerovum, and Stictodora, by various features. Heterophyes differs from Heterophyopsis in that the latter has an elongated body and also two obliquely tandem testes
  3. In H. heterophyes, this is a freshwater or brackish water snail belonging to one of the genera Pirenella (in Egypt), Cerithidia (in Japan), or Tarebia (in Hawaii); M. yokagawai infects members of the snail genus Semisulcospira. The hatched miracidium penetrates the intestine of the snail and transforms into a sporocyst in the digestive gland

H. heterophyes is a small trematode, ranging up to 1.4mm long and 0.5mm wide. It is covered with scale-like spikes and those spikes can range from 50-62. Their pharynx is completely developed and connected to the cecum of the small intestines. Their sucker (mouth) is covered with spikes and its covering the genital opening Heterophyiasis is a parasitic infection caused by the fluke Heterophyes heterophyes. The parasite is typically found in Egypt and other areas of the Middle East and Asia. Flukes are flat, leaf-like parasites that live inside the body of animals or humans. Fluke is the common name for any member of the class Trematoda

Taking also the literature into account it is concluded that man is a highly susceptible host forH. heterophyes, and that probablyH. aequalis andH. dispar may reach reproductive maturity in humans also. The described wide host range ofH. aequalis appears to be more typical for Heterophyidae than the comparably narrow host range ofH. heterophyes Heterophyiasis is infection with the intestinal fluke Heterophyes heterophyes, which is acquired by eating infected raw or undercooked fish from freshwater or brackish water.

Differential Interference Contrast Image Gallery Intestinal Fluke (Heterophyes)Members of the genus Heterophyes are intestinal flukes that average 1.5 millimeters in length. The most common of the ten species that belong to the genus is Heterophyes heterophyes, which is responsible for the condition known as heterophyiasis in humans, but may also be found in foxes, dogs, and cats Heterophyes heterophyes is common in Asia, North Africa, the Middle East and southern Europe. The main distribution areas are Egypt, Iran and Korea. Development cycle and infestation. The embryonated eggs of the intestinal leech are excreted with the faeces and removed by marine gill snails such as z. B. Potamides conicus ( Syn . The adult is flat, oval, fleshy measure (20-75) µm × (8-20) µm & covered with spines. Oral sucker is subterminal & ventral sucker is 3-4 times larger than oral sucker In 1923 Kobayashi and Khalil both observed that Heterophyes encysted in the Egyptian mullet, and Khalil experimentally infected cats. A very common marine snail, Pirenetta canica, occurs in lake Alánzala and harbours four different cercariae. One of these is a lophocercous cercana -which experimentally encysts in laboratory fed Gombusia. These fed to a laboratory bred dog gave rise to. Metagonimus yokogawai adult flukes are minute intestinal flukes (1-2.5 mm in length) that resemble Heterophyes heterophyes. An important distinctive feature is the position of the ventral sucker (genitoacetabulum), which is to the side of the midline and closely associated with the genital pore Heterophyes heterophyes are endemic in Africa, Asia, and tne Middle East. The life cycle of our little friends start when a snail eats the embryonated egg of the parasite. The embryonated eggs are released into water in a form of fecal matter from the vertebrate host. Once the egg is in the snail, the first intermediate host, the eggs hatch to.
