| polymerase chain reaction-identification of dirofilaria repens and dirofilaria immitis. | on the basis of known dna sequences of dirofilaria repens and d. immitis we designed specific primers for the amplification by polymerase chain reaction (pcr) of the dna from the two species. the pcr-based identification was found to be unambiguous and allowed specific diagnosis of microfilariae in blood samples, of developing larvae in the mosquito vector and of immature adults in bioptic material, overcoming the serious constraints of the morphological separation of these filarial parasites at ... | 1996 | 8939053 |
| human infection with dirofilaria repens in malaysia. | human dirofilariasis is a rare infection in malaysia. thus far, only two human cases have been reported viz. dirofilaria immitis and d. (nochtiella) repens and in both instances, adult worms were recovered from infected patients. the two cases reported in the present study, one from melaka and the other from penang, were diagnosed histologically. based on the diagnostic criteria for identifying dirofilaria in tissue sections, the parasites were identified as d. (nochtiella) repens. | 1996 | 8960220 |

| importance in france of the infestation by dirofilaria (nochtiella) repens in dogs. | the presence of dirofilaria repens has been mentioned in europe, in africa and in asia, in different carnivores (dogs, foxes, cats, lions). in europe the nematode has been reported in dogs, cats and foxes and the countries concerned by native cases are italy, spain, greece, yugoslavia and france. in france, until now, d. repens has been described, among animals, only in dogs. the first undoubted report dates back to 1953. later, the prevalence was studied through widespread surveys (1986-1988-19 ... | 1997 | 9802099 |
| advances in the identification of dirofilaria repens and dirofilaria immitis by a pcr-based approach. | the differential epidemiology of d. repens and d. immitis is still poorly understood due to the lack of a diagnostic method which would make possible the routine identification of these parasites as developing larvae either in the vector or in unsuitable hosts, including man. the pcr-based method here described allows: i) the unambiguous identification of mature and immature adult worms in bioptic material, of microfilariae in blood samples and of developing larvae in mosquito vectors; ii) the a ... | 1997 | 9802101 |
| research of canine filariasis in trapani province (western sicily). morphology on sem of male dirofilaria repens. | the prevalence of canine filariasis was investigated in 4 municipalities of trapani province (campobello di mazara, castelvetrano, marsala and mazara del vallo), an area where 8 human cases of dirofilariasis due to dirofilaria (nochtiella) repens have occurred during the last decade. blood samples were collected late in the afternoon, during august and september 1995, and examined by knott technique for the presence of microfilariae. sixtythree (29.3%) out of 215 domestic dogs (98 males, 117 fem ... | 1997 | 9802102 |
| pitfalls and difficulties in histological diagnosis of human dirofilariasis due to dirofilaria (nochtiella) repens. | the authors have conducted a histologic study of over 90 cases of dirofilaria infection in man due to dirofilaria repens, the most extensive study of its kind in the world. on the basis of their findings, they illustrate the diagnostic difficulties that may arise when regressive phenomena render the parasite's morphologic characteristics largely or completely unrecognizable. these phenomena are due to the death of the filaria inside the inflammatory nodule weeks or months prior to surgical remov ... | 1999 | 10342109 |
| breast infection due to dirofilaria repens: report of two new italian cases and revision of the literature. | two new cases of human dirofilariasis, occurred in women aged 46 and 52 years, respectively, both living in lombardy (northern italy) are reported. dirofilaria repens nematodes were localised in the breast in both cases. in one of them the parasite was accidentally extracted while the patient underwent a fine needle aspirate. the international literature records 30 cases of breast dirofilariasis. except in rare cases, the parasite was located subcutaneously in the breast, and nested in a nodule. ... | 1998 | 10376282 |
| presence of dirofilaria repens and an insect immunocyte (plasmatocyte) in a human subcutaneous nodule, induced by a mosquito bite. | it is well known that the nematode dirofilaria repens is transmitted to humans by vector mosquito bite. examination of a fine needle aspiration biopsy drawn from a month-old nodule on the chest of a woman, residing in garlasco, province of pavia, northern italy, revealed the presence of not only one immature female of d. repens, but also some scattered cells that we believe to be mosquito's blood cells, plasmatocytes (immunocytes). we presume that plasmatocytes were carried into the bite wound w ... | 1998 | 10376295 |

| dirofilaria repens infection in a dog in israel. | only one case of canine infection with dirofilaria repens has been reported in israel to date; this occurred in 1934. this publication, 65 years later, represents the second case of d. repens infection in a dog in israel. this dog was infected locally since it was born in israel and was never taken abroad, suggesting that the life cycle of the filaria was completed in israel. since dogs, cats, and foxes serve as a reservoir for the filaria and these are abundant in israel, and mosquitoes of the ... | 1999 | 10548301 |
| [human dirofilariasis in corsica: a new local case. review of reported cases]. | a case of human dirofilariasis with dirofilaria (nochtiella) repens, located in a subcutaneous nodule of the arch of the foot is reported in a 64-year-old man living in the surroundings of porto vecchio in corsica. the histological examination of this nodule has revealed a gravid female nematode, dead some weeks or months before its surgical excision. it is the second case of human dirofilariasis observed in a patient living on the island. the authors are surprised by the number of patients repo ... | 1999 | 10690464 |
| histopathological diagnosis of subcutaneous dirofilaria repens infection in humans. | the host tissue response in humans, based on a study of biopsies of 14 subcutaneous nodules caused by dirofilaria repens is described. the response was characterized by accumulation of eosinophilic material or eosinophilic pus adjacent to the parasite with surrounding granulomatous inflammation associated with extensive eosinophil infiltration of the surrounding tissue. unlike with fungal lesions, fat necrosis was conspicuously absent. nodules were all less than 3 cm in size. fifteen percent of ... | 1999 | 10774712 |
