[Characterization of Teladorsagia circumcincta and T. trifurcata. I. Epidemiological and biological aspects].

The natural infections of sheep were studied in six biotopes, in order to determine periods, biotopes and type of sheep at risk. Experimental infections were realized in order to assess the fertility of both Teladorsagia. T. trifurcata was more frequent in autumn and spring, among lambs and in biotopes where the climate was not contrasted. T. trifurcata produced more eggs/female then T. circumcincta.

The effect of strategic anthelmintic treatment on the breeding performance and survival of ewes naturally infected with gastro-intestinal strongyles and protostrongylids.

In two trials, batches of ewes naturally infected with gastro-intestinal strongyles and protostrongylids (small lungworms) were treated with fenbendazole (10 mg/kg body weight) and morantel tartrate (8 mg/kg body weight) at strategic periods. In the first trial, treatment with fenbendazole during midgestation and early lactation, reduced miscarriages, stillbirths, mortality of ewes and their offspring. In the second trial, batches of ewes were treated wither with fenbendazole or with morantel tartrate or a combination of both at different strategic periods. In all the treated groups there were reductions in the mortality of ewes and their offspring which varied according to the regime of treatment and the nature of the anthelmintic used. The excessive mortality related to the presence of these parasites was 3.62% in ewes and 13.8 in lambs. For the former, Protostrongylids and gastro-intestinal strongyles played an equal role; Protostrongylids of ewes were the main cause of worm-induced mortality for the latter. The reduction in the output of strongyle eggs and lungworm larvae paralleled the breeding performance and mortality rate of animals.

[Characteristics of Ostertagia sp. populations in naturally infested sheep in the region of Moulay-Bouazza (Morocco)].

Sixty-six abomasa of ewes were collected monthly at the slaughter-house of Moulay-Bouazza (Morocco) during two years. The characteristics of the population of Ostertagia (mostly O. circumcincta) were studied: number of eggs per female, vulvar polymorphism, length, sex-ratio and size of the worm-burden. These parameters were interrelated and could account for the seasonal variations of the number of eggs per female.

[Characterization of areas at parasitic risk for sheep reared by open grazing on the ranges of the Causses. 2. Protostrongylids].

Two pastures out of three in Causse (Center of France) were studied in June 1981 in order to characterize areas at risk for Protostrongylids (small lung-worms). These pastures were grazed in rotation by a flock of 50 Lacaune ewes. Each pasture was divided into 13 areas on mixed criteria related either to vegetation or use of space by the ewes. The following parameters were measured on each area: density of the intermediate hosts (Molluscs), their rate of infection, fecal biomass, type of vegetation and herbage biomass, rate of utilization by the ewes. The potential infectivity of the areas were related to the percentage of banded Cepaea sp., fecal biomass, percentage of the area covered by shrubs (Buxus sempervirens and Juniperus communis) and by Carex humilis.

Comparison between tracer calves and herbage samplings for the assessment of pasture infectivity in trichostrongylosis of cattle.

Two trials were designed in "Haute Normandie" to assess the value of the number of third stage larvae in herbage samples for monitoring the infection of cattle. Two techniques of sampling were used and were compared to the actual infection of tracer calves. An index of infectivity of the pasture was defined: the number of third stage larvae in 1 kg of dry matter of herbage multiplied by the quantity of grass (dry matter) ingested by calves. There was a significant correlation between this index and the actual worm burdens of tracer calves when parasites were numbered by genera, and for herbage samplings done according to "classical" techniques. The correlation is improved when data are combined from samples taken "close to fecal pats" and "far from fecal pats".

[Estimation of the infestation of mollusks by protostrongylids: parameters used and their interrelation].

Several parameters were utilized in order to estimate the infection of Mollusc by Protostrongylids. It was demonstrated that the prevalence, the number of larvae per snail and the aggregation were linked either in experimental infections or natural ones. In the former, prevalence was more related to rate of infection than to the aggregation. On the contrary the prevalence was mostly depending on overdispersion in field infections.

Egg output of Graphidium strigosum (Nematoda ) in low-level prime infection of rabbits.

Rabbits of Moroccan local breed were infected with larvae of G. strigosum obtained from a wild strain (100 larvae/animal) which had undergone two different durations of storage at +4 degrees C. A long storage (10 months) induced the inhibition of the larval development at a low-rate. A shorter storage of 3 months permitted the development into adults: the prepatent period was 5 weeks and the patent period lasted over 21 weeks post infection. The egg output expressed in eggs per gram was negatively correlated to the dry matter of faeces.

On some factors influencing the output of the larvae of Protostrongylids of sheep in natural infections.

The output of first stage Protostrongylid larvae of sheep was studied in natural infections. Three sets of observations were obtained from October 1977 to December 1978 in three regions. The fauna was characterized by the high prevalence of Muellerius and Neostrongylus. The larval output varied with the species harboured by sheep and with the density of worm populations. Anthelmintic treatments influenced the fecundity of worms. The age of the animals was an important cause of variation in the size of larval output; a rise of the latter was observed in pregnant ewes at the period of lambing. A seasonal variation in output was recorded.

The distribution of ringworm lesions in cattle naturally infected by Trichophyton verrucosum.

Eighty-seven Friesian Black Pied, males and females of various ages, were examined in the course of an outbreak of T. verrucosum. The site of ringworm lesions is dependent on the sex and age of animal. Sex is the key-factor for animals older than 12 months. Characteristic locations for lesions are: thorax and limbs for cows and heifers, ocular regions for young calves, dewlap and intermaxillary space for bulls. It seems that the differences observed in the frequency of the localisations of lesions among the various groups of animals are mostly due to behavioural reasons. The dissemination of lesions is probably not centrifugal but at random.
