| 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 |
| adult dirofilaria repens in a subcutaneous granuloma on the chest of a dog. | a 10-year-old, 9 kg, intact male crossbred dog was treated for nasal mites with milbemycin oxime using a dose of 1 mg/kg bodyweight orally, three times at 10-day intervals. one month after the initiation of this treatment a subcutaneous nodule developed on the sternum of the dog. the nodule was removed and found to contain a single, 82 mm long, thread-like nematode. several exotic parasites were suspected as possibilities because the dog had been imported to norway from south africa. microfilari ... | 1998 | 9888115 |
| ocular filariasis: not strictly tropical. | a 65-year-old man consulted for a discomfort in the right eye that had suddenly appeared the evening before. the examination revealed a white worm localized under the temporal bulbar conjunctiva. after extraction, the parasitological characteristics identified the worm as dirofilaria repens (nochtiella subgenus). this is a parasite of canids and felids, usually nonpathogenic to humans, but which can be transmitted through mosquito bites, especially around the mediterranean basin. the simple extr ... | 1999 | 10202297 |
| human dirofilaria repens infection in hungary: a case in the spermatic cord and a review of the literature. | orchiectomy was performed in a 37-year-old hungarian man exhibiting a swelling in his right testicle. histology revealed a nodule attached to the spermatic cord, consisting of a granulomatous tissue around sections of a nematode. the worm was identified as dirofilaria repens, an uncommon parasite in hungary. as the patient had been abroad only in italy where cases of dirofilariosis in dogs and humans are relatively frequent, it is assumed that the infection might have been acquired in that count ... | 1999 | 10213931 |
| 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 |
