The first and only study on gastrointestinal parasites of wild rodents in the Island of Santa Catarina was done in 1987. The aim of this study was to identify intestinal parasites from wild rodents in Santo Amaro da Imperatriz and Santa Catariana Island, and to compare the richness and composition of the gastrointestinal parasite community of both areas. Rodents were captured with live traps, and feces were screened using the sedimentation method and optical microscopy. The following species of rodents were captured in the two areas: Akodon montensis, Euryoryzomys russatus, Oligoryzomys nigripes and Nectomys squamipes. In Santo Amaro da Impetratriz, prevalent parasites were: A. montensis (51%), E. russatus (62%), O. nigripes (53%) and N. squamipes (20%). From the Island of Santa Catarina the rodent prevalence rates were: A. montensis (43%), E. russatus (59%), O. nigripes (30%) and N. squamipes (33%) and the collected parasites were: Hymenolepis sp., Longistriata sp., Strongyloides sp., Hassalstrongylus sp., Syphacia sp., Trichomonas sp., Ancylostomidae, Trichuridae, Oxyuridae and Eucoccidiorida. The species richness (10.6 ± 0.7) of the endoparasite comunity in the area located on the continent was higher (p < 0.01) and different (p = 0.001) from that of the area located on the island (6.9 ± 0.5).

Przewalski’S Horse

Abstract The Przewalski’s horse (Equus ferus przewalskii, Poljakov, 1881) is an endangered subspecies of wild horses (Equus ferus) native to steppes of Central Asia. In 2015, the Program of Establishing of a Semi-Free Population of the Przewalski’s Horse in the Orenburg Reserve was launched by FGFI “Orenburg Reserves”. The first group of 6 Przewalski’s horses (2 males and 4 females) born in the semi-reserve Le Villaret, France, was transported to the Orenburg Reserve. Th e aim of this work was to investigate the species composition of the intestinal parasite community and to monitor the dynamics of the parasite infection of the newly established Przewalski’s horse population. The level of infection by gastrointestinal parasites within the horses was examined by the McMaster method. Gastrointestinal parasites were collected in vivo after deworming of the horses with macrocyclic lactone drug “Univerm” (0.2 % aversectin C, PharmBioMed, Russia). Totally, 20 species of parasites were found: 19 species of nematodes (species of the family Strongylidae and Habronema muscae) and one species of botflies from the genus Gasterophilus. Th e widest species diversity (18 species from 8 genera) was observed in strongylids: 2 species from the subfamily Strongylinae and 16 species from Cyathostominae. Distribution of strongylid species between ten prevalence classes revealed a bimodal structure (“core-satellite” mode) of the strongylid community. Th e results obtained in this study are to be considered as the initial data for the further parasitological monitoring of Przewalski’s horses at the Orenburg State Reserve.

Abstract The study was performed to investigate the gastrointestinal parasite fauna using the method of diagnostic deworming in own modification in 29 Polish primitive horses (Equus caballus) from the Roztocze National Park, south-east of Poland. The parasite community was comprised of 35 species represented by three nematode families (Strongylidae, Ascaridae, Habronematidae), one cestode family (Anoplocephalidae) and larvae of insects from the family Gasterophilidae (Diptera). Strongylidae being 100 % prevalent was represented by 31 species from the subfamily Strongylinae (6 species) and Cyathostominae (25 species). Parascaris equorum was recorded in 48.3 %, Habronema muscae in 55.2 %, tapeworms (Anoplocephala perfoliata) in 24.1 % and Gasterophilus intestinalis larvae in 41.4 % of horses surveyed. The present results showed high prevalence of pathogenic intestinal parasites, which create the risk of health problems for horses living free in the reserve as well as stabled horses, when rarely treated.

ABSTRACT Gastrointestinal parasites are important, since they can cause a decrese in the performance of swine. The occurrence of parasites in pig farms can create economic losses such as reduction in the value of carcasses and increasing expenses with medicines and veterinary assistance. This study aimed at investigating the occurrence of intestinal parasites in different phases of production reared pigs in intensive prodution systems in the western region of the State of Santa Catarina. A total of 403 fecal samples were analyzed, of which 51.86% were positive for one or more parasites in different phases of production. Finishing pigs had the highest prevalence of parasites (60.19%) followed by nursery pigs (55.44%), pigs in breading sows (50.49%), and suckling piglets (40.81%). Strongylida parasites had higher occurrence (28.78%), and were also the most frequent in the finishing, breading sows, and nursery phases. Coccidia were more occurrent in suckling piglets. This study highlights the need of implementing suitable antiparasitic control measures in all phases of swine production associated with a surveillance system for the diagnosis of endoparasite infection in pigs. Our results demonstrate that endoparasites are highly occurring in pigs, even in intensive system animals on technified farms.

Background: FAffaMAlanCHArt (FAMACHA) is a technique for treating the animals infested with gastrointestinal parasites by using clinical anaemia as the determinant. The test is based on the assessment of colour variation of the conjunctival mucous membrane. Methods: In the present study FAMACHA has been standardized and used to correlate the anaemic status of goats with faecal egg count (gastro intestinal parasites) and blood profile. On the basis of FAMACHA score and faecal egg count, the goats were treated with benzimidazole compound and macrocyclic lactone. Result: The result indicated significant (P less than 0.05) reduction in the faecal egg count of Haemonchus spp from 1200±155.76 to 525±75, Strongyloides spp from 469.57±77.37 to 78.26±33.83 and Eimeria spp from 900±240.05 to 195.65±55.34 respectively. FAMACHA score of anaemic goats improved from 4.08±0.11 to 3.2±0.13. Mean haemoglobin (g/dl), packed cell volume (PCV), red blood cell (RBC) and white blood cell (WBC) improved from 8.33 to 8.99, 22.66 to 24.86, 13.73 to 14.76 and 18029 to 19894, respectively which indicated clinical improvement. Highly significant (P less than 0.01) correlation was observed between the FAMACHA score and the haemoglobin level. It could be concluded that FAMACHA is a very handy tool to detect anaemic status of the animals and correlate with gastrointestinal parasitic load.

AbstractThis study provides insights about the diversity, prevalence and distribution of alpine wild galliformes gastrointestinal parasite community, trying to fill a gap in the scientific information currently available in scientific literature. The analysis included three host species: 77 rock partridge (Alectoris graeca saxatilis), 83 black grouse (Tetrao tetrix tetrix) and 26 rock ptarmigan (Lagopus muta helveticus) shot during the hunting seasons 2008–2015. Parasites isolated were Ascaridia compar, Capillaria caudinflata and cestodes. The rock ptarmigan was free from gastrointestinal parasites, whereas the most prevalent helminth (37%) was A. compar in both black grouse and rock partridge. C. caudinflata occurrence was significantly higher in black grouse (prevalence = 10%, mean abundance = 0.6 parasites/sampled animal) than in rock partridge (prevalence = 1.20%, mean abundance = 0.01 parasites/sampled animal). Significant differences were detected among hunting districts. A. compar was found with a significant higher degree of infestation in the hunting districts in the northern part of the study area whereas cestodes abundance was higher in Lanzo Valley. Quantitative analysis of risk factors was carried out using a generalized linear model (GLM) only on the most common parasite (A. compar). Latitude was the only factors associated with infestation risk (OR = 52.4). This study provides information on the composition and variability of the parasite community in the alpine Galliformes species.

AbstractLarge carnivores of Africa, such as lions (Panthera leo), suffer from prey depletion and habitat fragmentation, that possibly impact the composition of the gastrointestinal parasite community. West African lions are particularly important, as this population is critically endangered and yet little is known of their gastrointestinal parasite community, which can reflect the health and resilience of the host population. From fecal samples collected in the W-Arly-Pendjari (WAP) transboundary protected area complex in Burkina Faso and Niger, we identified 309 oocysts of at least five different species using fecal flotation and sedimentation tests. We also compared these gastrointestinal parasites to other results from surveys of lions from Southern and East African regions and found similar taxa to previous surveys, but lower species richness across West African samples.

SummaryThe present study was conducted to evaluate the prevalence of gastrointestinal and cardio-respiratory parasites in dogs in Liguria (northwest Italy) which is a region that has scarcely been studied. A total of 450 dogs (260 males and 190 females) were enrolled in the study from 2009 and 2013. All dogs lived in a rural or semi-rural environment in the provinces of Imperia (n = 352) or Savona (n = 98), Liguria. Coprological examinations showed that 197 dogs (43.8 %, CI 38.7-48.9 %) were infected by parasites. Specifically, 3.3 % of the dogs presented only cardio-respiratory species, 32.4 % only intestinal species, and 8.0 % presented a mixed infection.The most frequent intestinal parasites wereToxocara canis(20 %),Trichuris vulpis(17.8 %), Ancylostomatidae (12 %), Coccidia (2.7 %),Aonchotheca putorii(1.8 %) andToxascaris leonina(1.8 %). The cardio-respiratory species found wereEucoleus aerophilus(9.6 %),Eucoleus boehmi(1.6 %),Angiostrongylus vasorum(0.7 %), andCrenosoma vulpis(0.2 %). A total of 116 dogs (25.8 %) were parasitized by a single species, multiple infections were observed in 81 dogs (18.0 %) up to a six-order infection.This preliminary study highlighted that the prevalence of intestinal parasites in investigated area is high. Cardio respiratory parasites were detected in an area that has not been investigated before. The creation of a more extensive sampling programme of the area, on a provincial basis in order to build a more detailed map of prevalences for different species of dog parasites throughout Liguria, a more extensive sampling programme of the area needs to be created - ideally for each province.

SUMMARYExperimental data establish that interactions exist between species of intestinal helminths during concurrent infections in rodents, the strongest effects being mediated through the host's immune responses. Detecting immune-mediated relationships in wild rodent populations has been fraught with problems and published data do not support a major role for interactions in structuring helminth communities. Helminths in wild rodents show predictable patterns of seasonal, host age-dependent and spatial variation in species richness and in abundance of core species. When these are controlled for, patterns of co-infection compatible with synergistic interactions can be demonstrated. At least one of these, the positive relationship betweenHeligmosomoides polygyrusand species richness of other helminths has been demonstrated in three totally independent data-sets. Collectively, they explain only a small percentage of the variance/deviance in abundance data and at this level are unlikely to play a major role in structuring helminth communities, although they may be important in the more heavily infected wood mice. Current worm burdens underestimate the possibility that earlier interactions through the immune system have taken place, and therefore interactions may have a greater role to play than is immediately evident from current worm burdens. Longitudinal studies are proposed to resolve this issue.

Intestinal Parasitosis

Introduction: Nowadays in our state, intestinal parasitic diseases are still endemic, with a greater frequency in rural and mountainous urban areas. After the years have elapsed since the last national survey, it was necessary to carry out a new survey to know the prevalence rates of intestinal parasitosis and to compare the results obtained between both studies. Such knowledge would be of great value in developing health strategies and designing intestinal parasitic infection control programs. Objective: to determine the current prevalence rates of intestinal parasites, to compare the results with those of the survey obtained. Methods: a random cross-sectional descriptive study was carried out during the months of December 2018 to March 2019 in a random sample of both sexes from the population of urban communities and the province of Zacatecas, Zac. Each one had a stool sample collected that was analyzed by the direct examination method, the Willis concentration technique, and the Kato-Katz examination; A questionnaire was also applied to them. Results: when comparing the results of the national and state surveys of intestinal parasitic infections carried out in 2009 and 2018, it was found that, in general, infections by parasites decreased, both helminths and pathogenic protozoa, although those infected with commensals increased their frequency in that of 2019. There was also a decrease in the frequency of infections by all species of soil-transmitted helminths, Trichuris trichiura, Ascaris lumbricoides, ancylostomideos, and Strongyloides stercoralis, as well as by the pathogenic protozoa Giardia lamblia and Entamoeba histolitica. Conclusions: when comparing the results of national and state surveys of intestinal parasite infections carried out in 2018 and 2019, it was found that in general the frequencies of infections with intestinal parasites decreased. The finding in both studies of a higher frequency of infection with parasites or commensals in the group aged 5 to 14 years (school age), supports the recommendation to place emphasis on control programs for intestinal parasites in this age group.
