Background: Swine species are an important source of meat production worldwide, except in Islamic countries where pig breeding and pork consumption are forbidden. Hence, they are often neglected in these regions. A considerable number of wild boars (Sus scrofa) inhabit Iranian territories, particularly in dense forests of north, west and southwest of the country, but our knowledge regarding their parasites is very limited. Objective: The lack of a comprehensive record in this connection encouraged us to review the whole works of literature in the country. Methods: The current review presents all the information about the parasitic diseases of wild boar in Iran extracted from articles available in both Persian and English databases until June 2017. Results: So far, 8 genera of protozoa (Toxoplasma, Balanthidium, Tritrichomonas, Blastocystis, Entamoeba, Iodamoeba, Chilomastix and Sarcocystis) and 20 helminth species, including four cestode species, two trematode species, thirteen nematode species as well as a single species of Acanthocephala have been described in Iranian wild boars. Conclusion: This review sheds light on the veterinary and public health aspects of the parasitic diseases of wild boars in the country and alerts authorities for future preventive measures.

Helminth Infections

In a survey of 259 newly-imported rhesus monkeys, 5 species of nematode parasites were commonly found. Of these 5 species, Oesophagostomum spp. and Strongyloides fulleborni were implicated in the deaths of 3 monkeys. 5 other nematode species, 2 cestode species and 1 trematode species were also found; their pathogenicity is discussed. The results of treatment of parasitic infections with 6 different drugs is reported. Thiabendazole at an initial dose of 100 or 133 mg/kg and repeated at 50 mg/kg was found to be the most effective treatment against Oesophagostomum spp.

Abstract Until recently, the genus Oesophagostomum was the only Oesophagostominae occurring commonly in both domestic and wild suids of Europe. A few years ago, an alien oesophagostomin nematode Bourgelatia diducta was recorded in the wild boar population from southern Poland, and Vietnamese potbellied pig was blamed for introduction of this Far Eastern parasite. Apart from wild boars kept in captivity for meat production purposes, Vietnamese potbellied pigs can be raised in extensive, organic, or especially agrotourism farms, which constitutes an infection hazard to domestic pigs. The aim of the research was to determine and compare species composition of Oesophagostominae in wild boars from the natural environment, and in domestic pigs from extensively managed farms, located in the area where B. diducta was previously noted for the first time. A postmortem examination of the large intestines of 25 wild boars and 20 domestic pigs, each from different smallholdings, was conducted in the autumn and winter season of 2010- 2011. Oesophagostomum dentatum with coexisting O. quadrispinulatum were ascertained in swine, whereas the sole Bourgelatia diducta was recorded in wild boars. All the parasites occurred commonly in their hosts, with the prevalence of 80, 50 and 32% for O. dentatum, O. quadrispinulatum and B. diducta, respectively. Mean number of worms was many-fold higher in pigs, reaching 181 (range 1 to 2500) specimens in individual host, versus 3 (1-6) parasites in wild boars. A presumable influence of the alien nematode species on the European wild boar population as well as the potential for further spread of the parasite are elucidated

: Infections caused by Trypanosoma brucei, Trypanosoma cruzi, Leishmania spp., Entamoeba histolytica, Giardia lamblia, Plasmodium spp., and Trichomonas vaginalis, are part of a large list of human parasitic diseases. Together, they cause more than 500 million infections per year. These protozoa parasites affect both low- and high-income countries and their pharmacological treatment is limited. Therefore, new and more effective drugs in preclinical development could improve overall therapy for parasitic infections even when their mechanisms of action are unknown. In this review, a number of heterocyclic compounds (diamidine, guanidine, quinoline, benzimidazole, thiazole, diazanaphthalene, and their derivatives) reported as antiprotozoal agents are discussed as options for developing new pharmacological treatments for parasitic diseases.

Despite advances in medical knowledge, parasitic diseases remain a significant global health burden and their pharmacological treatment is often hampered by drug toxicity. Therefore, drug delivery systems may provide useful advantages when used in combination with conventional therapeutic compounds. Dendrimers are three-dimensional polymeric structures, characterized by a central core, branches and terminal functional groups. These nanostructures are known for their defined structure, great water solubility, biocompatibility and high encapsulation ability against a wide range of molecules. Furthermore, the high ratio between terminal groups and molecular volume render them a hopeful vector for drug delivery. These nanostructures offer several advantages compared to conventional drugs for the treatment of parasitic infection. Dendrimers deliver drugs to target sites with reduced dosage, solving side effects that occur with accepted marketed drugs. In recent years, extensive progress has been made towards the use of dendrimers for therapeutic, prophylactic and diagnostic purposes for the management of parasitic infections. The present review highlights the potential of several dendrimers in the management of parasitic diseases.

Buffalo is the most important livestock commodities for milk, meat production and several other multipurpose uses distributed densely from southern tarai to northern mid-hills in Nepal. Among several internal parasitic diseases fascioliasis is highly economic one caused by Fasciola in buffaloes. However, there are only few studies carried on prevalence of fascioliasis emphasizing buffaloes in relation to seasonal (summer and rainy, and winter) and altitudinal variations. Therefore, we examined prevalence of fascioliasis seasonally and vertically. For the purpose, we selected two districts of eastern Nepal and sampled from low altitude area known as Madhesha ranging from 175-200, Dhankuta from 800-1200 m, and Murtidhunga from 1800-2200 m elevation from the sea level, representing tarai, mid hills and high hills, respectively. Altogether from February 2013 to January 2014 at every two months interval we collected 798 fecal samples from buffaloes; 282 from Murtidhunga, 239 from Dhankuta and 277 from Madhesha. The samples were examined microscopically for the presence of Fasciola eggs using sedimentation technique. Results showed that overall prevalence of fascioliasis in buffaloes was 39.9% (319/798), ranging highest 42.6%in Madhesha followed by 39.7% in Murtidhunga and 37.2% in Dhankuta, respectively. The prevalence of fascioliasis was found to be significantly (p <0.05) high in winter (44.9%) comparing to rainy season (34.4%). The prevalence of fascioliasis in buffaloes was relatively higher in low altitude than high altitude, although it was not statistically significant (p <0.05). In our findings the female buffaloes showed higher prevalence for fascioliasis than in male. Since the fascioliasis in buffaloes is highly endemic, thus strategic deworming in high risk period is recommended along with measure to prevent pasture contamination with buffalo feces.

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.

Abstract Helminth infracommunities were studied at 174 sites of Latvia in seven hosts from six amphibian taxa of different taxonomical, ontogenic and ecological groups. They were described using a standard set of parasitological parameters, compared by ecological indices and linear discriminant analysis. Their species associations were identified by Kendall's rank correlation, but relationships with host size and waterbody area were analysed by zero-inflated Poisson and zero-inflated negative binomial regressions. The richest communities (25 species) were found in post-metamorphic semi-aquatic Pelophylax spp. frogs, which were dominated by trematode species of both adult and larval stages. Both larval and terrestrial hosts yielded depauperate trematode communities with accession of aquatic and soil-transmitted nematode species, respectively. Nematode loads peaked in terrestrial Bufo bufo. Helminth infracommunities suggested some differences in host microhabitat or food object selection not detected by their ecology studies. Associations were present in 96% of helminth species (on average, 7.3 associations per species) and dominated positive ones. Species richness and abundances, in most cases, were positively correlated with host size, which could be explained by increasing parasite intake rates over host ontogeny (trematode adult stages) or parasite accumulation (larval Alaria alata). Two larval diplostomid species (Strigea strigis, Tylodelphys excavata) had a negative relationship with host size, which could be caused by parasite-induced host mortality. The adult trematode abundances were higher in larger waterbodies, most likely due to their ecosystem richness, while higher larval abundances in smaller waterbodies could be caused by elevated infection rates under high host densities.
