Dirofilaria repens - an overview ScienceDirect Topic

Dirofilaria is an important genus of parasites that mainly infect canids (dog heartworm) and felines. The endemic areas include the Mediterranean region and some Middle Eastern countries. 833-838 In these areas, cases of human infection by Dirofilaria repens and Dirofilaria immitis have been reported During a blood meal, an infected mosquito ( Aedes, Anopheles, Culex, Mansonia) introduces third-stage filarial larvae of Dirofilaria repens onto the skin of the canine definitive host (but also occasionally humans, especially in Europe), where they penetrate into the bite wound . In the definitive host, the L3 larvae undergo two more molts into L4.

Dirofilaria repens occurrence, including the first autochthonous canine infection and the detection of D. repens DNA in the vector mosquito of Aedes vexans , was reported some years later. Currently, D. repens is well established in dog populations in the extreme southeast of the territory of the country [13, 15] Dirofilaria repens is exclusive to the Old World, infecting dogs and cats across Europe, Asia, and Africa. In Europe, the Mediterranean region is considered highly D. repens -endemic. The European range of D. repens seems to be expanding, with transmission has been documented as far north as Finland and East into European Russia Dirofilaria repens [upravit | editovat zdroj]. V ČR je častější než Dirofilaria immitis (v ČR jen 5 případů, ale stále se rozšiřuje a blíží se k Česku z klasických míst výskytu).; Nejčastější původce symptomatické dirofilariózy.

Dirofilaria is a genus of nematodes, or roundworms, in the family Onchocercidae.Some species cause dirofilariasis, a state of parasitic infection, in humans and other animals.. There are about 27 species in the genus. These are generally divided into two subgenera, Dirofilaria and Nochtiella. Some species are well-known parasites, including Dirofilaria immitis, the dog heartworm, Dirofilaria.

Dirofilaria repens is a nematode affecting domestic and wild canids, transmitted by several species of mosquitoes. It usually causes a non-pathogenic subcutaneous infection in dogs and is the principal agent of human dirofilariosis in the Old World. In the last decades, D. repens has increased in prevalence in areas where it has already been reported and its distribution range has expanded. In this study, we screened field-caught mosquitoes for presence of Dirofilaria spp. by using a polymerase chain reaction (PCR) assay. Potential occurrence of Dirofilaria repens and Dirofilaria immitis microfilariae was examined in 3,600 mosquitoes of eight species (Aedes vexans, Aedes cinereus, Aedes rossicus, Culex pipiens, Culiseta annulata, Ochlerotatus sticticus, Ochlerotatus cantans and. These include Dirofilaria ursi, a bear parasite transmitted by the black fly Simulium venustum, and D. roemeri, a wallaroo (a type of small kangaroo) parasite transmitted by the horse fly Dasybasis hebes; and the following mosquito-transmitted Dirofilaria species: D. repens in canids; D. carynodes and D. magnilarvatum in monkeys; D. scapiceps. Dirofilaria Repens Jak vypadá a kde žije? 1. Dirofilaria repens je červ vyskytující se v podkoží psů. Samečkové jsou 5-7 cm a samičky 10-17 cm dlouhé. Larvy (nazývané mikrofilárie) kolují v krevním oběhu a lze je prokázat pouze pod mikroskopem Using the PCR method, the presence of Dirofilaria repens and D. immitis microfilariae was examined in 8,400 mosquitoes of 8 species (Aedes vexans, Ae. cinereus, Ae. rossicus, Culex pipiens, Culiseta annulata, Ochlerotatus sticticus, Oc. cantans, and Oc. caspius)

Dirofilaria repens infection is much more difficult than D. immitis to diagnose and control in the reservoir population (microfilaremic dogs). In addition, lack of familiarity with D. repens infection could lead to lack of vigilance underestimation for this parasite Human dirofilariasis caused by Dirofilaria repens is a parasitic infection, currently considered to be an emerging zoonosis, that has been observed in many areas of the Old World. Dogs are the. To the Editor: Dirofilariosis caused by infection with the filarial nematode Dirofilaria repens is considered an emerging zoonosis in Europe ().The main reservoirs for this parasite are dogs and other carnivores. As is the case for other filarial species, mosquitoes transmit infectious third-stage larvae, which develop into fertile adults in their definitive vertebrate hosts Dirofilariasis is a zoonotic mosquito-borne disease known worldwide. In Europe, the species D. repens and D. immitis are present, which normally cause dirofilariasis in animals, most commonly in canids

Dirofilaria repens. Vlasovcovitý parazit napadající především psy a kočky, ale způsobuje i zoonózy objevující se u lidí včetně podkožních lézí Background Dirofilaria repens is a mosquito-transmitted, filarial nematode parasitizing dogs, cats and other carnivores. Recently, this parasite has spread in central Europe, including Poland Dirofilaria repens: emergence of autochthonous human infections in the Czech Republic (case reports The Dirofilaria species that most commonly cause human infection are D immitis (heartworm) and D repens. It is transmitted to humans through arthropods; mosquitoes are the vector for Dirofilaria . Infection with these nematodes, however, is independent of dog ownership, although residence in or travel to an area where canine dirofilariasis is. Dirofilariasis represents a zoonotic mosaic, which includes two main filarial species (Dirofilaria immitis and D. repens) that have adapted to canine, feline, and human hosts with distinct biological and clinical implications. At the same time, both D. immitis and D. repens are themselves hosts to symbiotic bacteria of the genus Wolbachia, the study of which has resulted in a profound shift in.

Dirofilaria repens. From Wikispecies. Jump to navigation Jump to search. Dirofilaria repens. Taxonavigation . Taxonavigation: Filarioidea. Dirofilaria repens typically causes a milder, subcutaneous infection in dogs and wild predators. It is the major parasite causing dirofilariasis in humans, with an increasing number of cases reported in Europe Dirofilaria repens is currently considered an emerging zoonosis in Europe. Agents and life cycle Filarial worms (Spirurida, Onchocercidae) are vector-borne nematodes infecting mainly dogs but also cats, ferrets, wild carnivores (fox, jackal, coyote, wolf, raccoons, wild felids, sea lion, black bear) and humans (McCall et al., 2008; Simón et al., 2012; Otranto and Deplazes, 2019)

Human dirofilariasis is a zoonotic infectious disease caused by the filarial nematodes of dogs Dirofilaria repens and Dirofilaria immitis. Depending on the species involved, human infections usually manifest as one cutaneous or visceral larva migrans that forms a painless nodule in the later course of disease Dirofilaria has longitudinal ridges, while L. loa does not L. loa has irregularly spaced cuticular bosses or bumps that are located along along the long axis of the worm Microfilariae are only rarely seen in human Dirofilaria infections; unlike L. loa , the microfilariae of D. repens do not have a sheath and the nuclei do not go all the way to the tip of the tai Dirofilaria repens is a well-recognized parasite of dogs and humans in southern Europe [1-4] in the Ukraine [5, 6] and southern Russia . Although cats appear to be competent hosts for D. repens , they are much more resistant to invasion and in endemic regions prevalence is considerably lower than in dogs [ 2 ] Dirofilaria species were identified by sequencing, confirmed by polymerase chain reaction of positive specimens using primers specific for D. immitis and D. repens. Dirofilaria DNA was detected in 3/154 (2%) of Ae. albopictus females examined: D. repens DNA in head‐thorax and abdomen of one collected 27th July; D. immitis in the abdomen of one collected 24th September; DNA of both D. immitis and D. repens in the head‐thorax of one collected 11th October 2002 In Europe, two Dirofilaria species, D. (D.) immitis and D. (N.) repens, occur which both cause animal as well as human dirofilariasis . The life cycle of Dirofilaria spp. involves mosquitoes and carnivores (mainly dogs and foxes, but also cats, ferrets, raccoons and bears) as intermediate and definitive hosts, respectively

The life cycle of D. repens is very similar but instead of migrating to the heart, the adult worms reside mostly in subcutaneous tissues. return to top. Morphology. In their natural hosts, Dirofilaria adult females are usually between 25 and 30 cm (10-12 inches) in length.
