“…Evidence from molecular studies suggests the presence of gene flow between the 2 species and their different occurrence seems to be based on the endemicity of the human species. In Italy, where A. lumbricoides is not endemic, most of the human infections are nowadays zoonotic and A. suum is the main causative agent of ascariasis (Cavallero et al ., 2021 ).…”

The World Health Organization (WHO) defines neglected tropical diseases (NTDs) as a diverse group of primarily infectious diseases, which disproportionately affect poor and marginalized populations worldwide. In this context, NTDs are responsible for important morbidity and mortality and justify a global response. Moreover, NTDs are relatively neglected by research and development as well as by funding, if compared with the magnitude of the public health problem they represent. This happens even though, unlike other infectious diseases, they can be prevented, controlled and eliminated by targeted public health interventions. NTDs are mainly prevalent in communities from low-income countries in tropical and sub-tropical areas but are also present in upper–middle-income countries, including several in Europe. Here, we provide an update on the most relevant parasitic endemic or imported NTDs in Italy and illustrate the rationale for the establishment of the Italian network on NTDs, an alliance of scientific societies, institutes, foundations, universities and non-profit organizations united to fight NTDs.

There is little evidence that the already described and accepted taxa of ascarids (Ascaris lumbricoides, A. suum, and A. ovis) infecting individuals of taxonomically distant groups (hominids, pigs, sheep, goats, and dogs) can be genetically or morphologically distinguished. However, despite described morphological differences, e.g., due to intraspecific variation, these are insufficient for species determination and may indicate differences amongst ascarids because of cross infections, hybrid production, and specific adaptations to hosts. Herein, the results of a molecular and morphological analysis of ascarids parasitising Sumatran orangutans (Pongo abelii Lesson, 1827) in native populations are presented. The research took place in the Bukit Lawang area, Indonesia, in 2009. Throughout the year, fresh faecal samples were collected regularly from 24 orangutans, and all were examined for the presence of nematode adults. Only five adult worms from two orangutan females were found during regular collection. Using the integrative taxonomic approach, the nematodes found were identified as A. lumbricoides. The significance of the find and its rarity is documented by the fact that this is the first confirmed finding of adult ascarids from an original orangutan site (not from a zoo) in more than 130 years (including the long-term study spanning the last 20 years focusing on orangutan parasites and natural antiparasitic drugs). More accurate morphometric parameters and genetic differences for the identification of ascarids were established. These parameters will be helpful for other findings in great apes and will also be suitable for further and precise determination of this parasite. The details distinguishing between male and female specimens are also stated and well defined. A comprehensive evaluation of the situation of Ascaris species parasitising orangutans, including a comparison with previously described orangutan parasite (i.e., A. satyri—species inquirenda), is discussed.

The work is devoted to analyzing literary sources and the results of public research on epizootology, epidemiology, and approaches to the fight against trichinosis – one of the most unsafe helminthiasis in animals and people. In the statistics, the primary nutrition is comprehensive, the path and the sources of invasion, the dynamics of infection of pigs and other creatures, now look at the circulation of Trichinella in nature and the biocenosis associated with humans, as well as the main directions of preventive entry. We conducted a study on the monitoring of trichinosis infestation. We found that the territory of Ukraine has a stationary unfavorable incidence of trichinosis in pigs, and the most significant number of pig carcasses infected with larvae – 76.5 % were registered in Mykolaioblast. Z'yasovanie natural causes of trichinosis, as revealed in the Transcarpathian, Mykolaiv, and Kharkiv regions. The dominating significance of the circulation of the bug is given to the invasion of the environment of the wild fauna lies the red fox. At the same time, there is an important creature in the circulation of the census between the synanthropic and natural centers. With laboratory studies of carcasses of creatures infected with Trichinella larvae, it is possible to show a significant advantage to the method of over-etching of muscles in piece stomach juice is equal to compressor trichineloscopy. These methods objectively characterize the intensity of invasion in skin creatures and show their role in the circulation of trichinosis. Due to the support of the European legislation, the first leaders are to introduce into the practice of veterinary medicine in Ukraine new methods for post-life and prosperous diagnosis of trichinosis. The system for the complex of entry into the prevention and elimination of trichinosis of creatures is guilty of including preventive measures and the prevention of endemic middle infections.
