“…(Padhi et al, 2017;Chowdhury et al, 2018;Sharma et al, 2019) As an intermediate host, these flies ingest embryonated eggs and primary-stage larvae while feeding on lacrimal secretions of definitive hosts, such as dogs, cats, foxes, wolves, rabbits, and humans. (Padhi et al, 2017;Sharma et al, 2019;Bojan et al, 2019) After the larvae mature into third instars, the flies land on a host's eye and release the infective larvae on the conjunctiva (Sharma et al, 2019).…”

Introduction: Parasitic infections of the eye are a major cause of ocular-surface diseases globally. While most infections are treatable, parasites can cause varying levels of damage mostly due to late diagnosis or misdiagnosis as a result of doctors' unfamiliarity with their characteristics of latency and crypsis, as well as lack of awareness by the patients. Case Reports: In this study, we present three cases of phthiriasis palpebrarum, thelaziasis, and ophthalmomyiasis, respectively. Two of the cases were treated at the clinic and did not recur. One patient refused treatment and was lost to follow-up. Discussion: By evaluating the natural histories, morphology, symptoms, clinical findings, and treatment of these parasitic diseases, we systematically analyzed several distinct and unique parasite characteristics, especially latency and crypsis. Furthermore, we have proposed specific examination techniques and methods as well as prevention and treatment strategies from these specific perspectives, aiming to prompt timely diagnoses and early interventions for these diseases by health care workers and improve the public's awareness of parasitic infections. Conclusion: Parasitosis on the ocular surface is a global infectious disease, and prevention strategies include maintaining personal and environmental hygiene and limiting contact with animals. We recommend that health care workers should enhance their ability to detect and diagnose these diseases while promoting the public's awareness of them in the context of our new perspectives.

“…This study reports the first cases of ocular thelaziosis by T. callipaeda in grey wolves from peripheral zones of the Italian Alps. Since the first report of T. callipaeda in wolves in Italy ( Otranto et al, 2007 ), other records on this host species have been published in different European countries such as Romania ( Mihalca et al, 2016 ), Serbia ( Bojan et al, 2019 ), Spain ( Nájera et al, 2020 ), and Greece ( Papadopoulos et al, 2021 ), demonstrating that this ecologically plastic canid is involved in the transmission cycle of T. callipaeda in diverse habitat types in Europe.…”

“…Infected dogs in this study were from the regions in Northern (43.58% from North Banat District and 28.94% from South Bačka District), Central (41.83% from Belgrade suburbia and 21.68% from Braničevo District), Eastern (47.50% from Bor District and 30.92% from Zaječar District) and Southern Serbia (25.00% from Pčinja District). Infection of wolves with T. callipaeda has recently been documented, with an overall prevalence of 38.1%(Gajić et al, 2019). Th is fi nding suggests the signifi cance of the epizootiological role of wolves as reservoirs of infection for thelazia, although other wild carnivores' role should also be addressed in the studies.…”

Zoonotic Helminthosis of Domestic and Wild Carnivores in the Epizootiologic Territory of Serbia

In the last decade, as the result of climate changes, there have been considerable changes in the parasitofauna of domestic and wild carnivores. The prevalence of the existing parasitic species has varied significantly, showing an increasing tendency, and some parasitic species not present before in this epizootiologic territory have been diagnosed as well. It is thought that the reason for such an epizootiological situation is increased presence of owners with their pet animals in the regions endemic for particular zoonotic helminthoses during summer holidays and touristic visits. This tendency has become especially conspicuous in the last several years characterized by warm winters and very hot summers due to global warming effects, with abundant atmospheric precipitation. Oral vaccination of foxes against rabies, regulated in Serbia by appropriate laws since 2010, has led to an increased number of foxes and rise of prevalence of the parasitic diseases for which foxes represent the infection source/reservoir. Continued urbanization of Serbian cities, with the extension of urban belts into the suburbia and recreational (“weekend”) settlements, lead to a closer contact of street dogs and owned dogs with foxes, which results in a significant change in the parasitic fauna of dogs. It is an additional factor, which in the chain fox - street dog - owned dog - human increases the risk and tendency for the occurrence of human infections with zoonotic endoparasites of wild and domestic carnivores. In order to reliably predict the degree of spread of particular zoonotic helminthoses in particular regions in Serbia, for which wild carnivores represent the infection source, it is necessary to institute continued monitoring of the parasitic fauna in this type of wild animals.
