| [the occurrence of broncho-pulmonary nematodes in sheep from emilia-romagna]. | in the present investigations 510 sheep have been examined for the presence of lungworm larvae: 342 (67,05%) of them proved positive. the identification of the parasites demonstrated the presence of dyctiocaulus filaria in 18,62% of the examined animals, muellerius capillaris in 50%, cystocaulus ocreatus in 26,86% and protostrongylus spp. in 12,35%. all positive flocks were positive for two or more genera of lungworms. | 1978 | 553276 |
| activity of luxabendazole against liver flukes, gastrointestinal roundworms, and lungworms in naturally infected sheep. | the anthelmintic potential of luxabendazole was investigated in sheep harboring mixed naturally acquired helminth infections. results were assessed by comparing worm counts of the treated groups (seven animals each) on days 7-8 posttreatment with those of the nontreated control group, except for protostrongylid lungworms, for which the changes in pre- and posttreatment group mean larval counts/g feces were assessed for intensity effect. a single oral treatment at doses of 10.0 or 12.5 mg/kg body ... | 1988 | 2974592 |
| on first-stage larval resistance under controlled conditions of three species of nematodes of the family protostrongylidae leiper, 1926. | a study was made on the survival of the first larval-stage of three species of the family protostrongylidae (cystocaulus ocreatus, muellerius capillaris and neostrongylus linearis). at every temperature (5, 12, 20, 26 and 36 degrees c) and humidity (100, 70 and 30%) combinations, the species which needed the least time to reach the pre-established (50, 75 and 95%) mortality rates was neostrongylus linearis. in all cases muellerius capillaris was the species needing the longest time to reach the ... | 1986 | 3813415 |

| relationship between the excretion of protostrongylid larvae in sheep in north-west spain and climatic conditions. | the relationship between different climatic factors (temperature, relative humidity and rainfall) and the pattern of lungworm larval excretion was studied in sheep under a continuous grazing pattern in north-west spain, where the climate is intermediate between sub-humid mediterranean with an atlantic tendency and european atlantic. over a period of one year, 44 animals were sampled once a month at random from a flock of 80 galician breed sheep, all over 4 years old. faeces were taken directly f ... | 1994 | 7829839 |
| ecological relations among first-stage larvae of four species of protostrongylidae (nematoda) within their ovine host. | competitive relations between protostrongylid nematodes parasitic in the ovine lung, using competition coefficients and asymptotic densities showed that two relatively scarce species (neostrongylus linearis and protostrongylus rufescens) exert strong competitive actions on the two most abundant species (cystocaulus ocreatus and muellerius capillaris). p. rufescens could lead to the disappearance of the more abundant species, if other compensatory factors did not exist in their life cycle. | 1996 | 8574249 |
