Protozoan Parasites

It is estimated that more than half of the human population, plus a much greater number of domestic and wild animals, suffer from parasitic infections. The magnitude of the problem can be illustrated by estimates of more than 100 million cases and 1 million deaths each year from malaria alone.

AbstractThe number of parasites followed the rapid growing of human population worldwide, not only in developing but also in developed countries. Many of them are diagnosed in children and adolescents. The occurrence of selected intestinal endoparasites in children coming from areas with low hygienic and socioeconomic status was studied. Out of 81 faecal samples examined, 46 (56.8 %) were positive for presence of intestinal parasites. From helminths, Ascaris lumbricoides was found to be the leading parasite (24.7 %), followed by Trichuris trichiura (17.3 %). Tapeworm Taenia spp. eggs were detected in 4.9 % of examined children. From protozoan parasites Cryptosporidium spp. was observed in 36 children (44.4 %) and Giardia intestinalis in 20 children (24.7 %). The occurrence of these epidemiologically low risky parasites in Roma children population suggests low hygienic standard in the Roma settlements.

Parasites have, over the centuries, been responsible for high mortalities among humans and domestic and wild animals. The presence of parasitic infections has made vast areas of the world uninhabitable for both humans and animals. Major strengths of Canadian parasitology include wildlife parasitology, systematics, and taxonomy. Experimental studies in parasitology are limited; in particular the subdisciplines of parasite molecular and cellular biology, biochemistry, immunology, and neurobiology are very limited. There is concern that we will not be able to maintain the quality of Canadian research in parasitology, particularly in the emerging new technologies. It is greatly to the credit of those early Canadian parasitologists, who laid the foundations for today's advances in parasitology, that a relatively small group of approximately 100 professional parasitologists has today reached a very high standard of parasitological research. The next 25 years will be an exciting period as new insights allow us to further understand the complexity of host–parasite relationships. The development of new vaccines, drugs, and vector control point to significant reductions in parasitic infections.

When the white man came to Nyasaland—now Malawi—the country teemed with wildlife. The next hundred years saw a fivefold increase in the human population and an immense depletion of the wild animals. Today, although protected only in the five national parks and three game sanctuaries, the wildlife is again increasing, and the main tasks are to develop the reserves and educate the young especially to value them.

Ticks are vectors for many infectious diseases and represent a constant threat to human population and other animals, especially with respect to zoonoses. Th e cause of granulocyte anaplasmosis Anaplasma phagocytophilum is a gram-negative, obligate intracellular bacterium that infects people as well as various domestic and wild animals. Th e agent is spread worldwide, persisting in the natural environment through an enzootic circle between ticks and their hosting vertebrae. Th e aim of this paper is to demonstrate the distribution of ticks’ infection with Anaplasma phagocytophilum in the territory of the Autonomous Province of Vojvodina. Ticks were collected at ten locations in the Autonomous Province of Vojvodina, Serbia, which are a rural habitat for ticks. By applying the nested PCR method, the ticks were examined for the presence of specifi c DNA p44/msp2 Anaplasma phagocytphilum. Of the ten examined pools of ticks collected in the area of the Autonomous Province of Vojvodina, the presence of genome of the agent Anaplasma phagocytophilum was confi rmed in six pools applying the PCR method. In five pools of ticks of the species Ixodes ricinus, presence of agent Anaplasma phagocytophilum was confi rmed. Th ese ticks were found at the following locations: Poplar Research Institute (2 locations), Fruška gora (2 locations) Poloj-forest Bačka Palanka (1 location). In one pool of ticks of the species Dermacentor reticulatus from the location Poloj-forest Bačka Palanka, we confi rmed the presence of Anaplasma phagocytophilum genome. This infection can be a problem for public health, so further and more comprehensive acharological and epidemiological research is necessary in the Autonomous Province of Vojvodina.

The World

In the last two decades the world had faced three respiratory syndrome outbreaks incurred by Coronavirus. Though the wild animals are the primary carriers of the virus, the human population managed to survive sacrificing more than 1,600 lives from 2002 to 2012. But the current virus outbreak has already taken more than 2,462 lives since 22 February 2020. In the first few days, when the cases were being introduced under light, there were no treatment for the infection and the unleashed spread demands to be analyzed to see the pattern of the outbreak. This manuscript aims to look into the growth map of the COVID-19 outbreak under mathematical growth functions and tries to understand which growth pattern assembles the scenario for the cases.

The aim of this study is development of a model for monitoring and control of vector-transmitted diseases, which manifest increasing tendency during the last few decades. Th e main infection reservoirs are domestic and wild animals as well as various birds, and the disease is transmitted to humans indirectly - by vectors. Recently detected epidemics of Dengue virus, Chikungunya and West Nile virus in countries where these diseases are not common strongly indicate the expansion of infections transmitted by mosquitoes and other vectors, and are the consequence of climatic changes, international trade and travelling. Currently, there are neither vaccines nor specific antiviral therapy for these infections, while the efforts put on vector control did not halt the rapid increase and global spread of the disease. Serological studies and molecular investigation on humans, mosquitoes, horses and birds have suggested the activity of flaviviruses in Serbia. The obtained information on fl avivirus infections in our region are of use in modelling the control and vector monitoring and the prevention of these infections in humans.

AbstractWild animals have been implicated as the origin of SARS-CoV-2, but it is largely unknown how the virus affects most wildlife species and if wildlife could ultimately serve as a reservoir for maintaining the virus outside the human population. Here we show that several common peridomestic species, including deer mice, bushy-tailed woodrats, and striped skunks, are susceptible to infection and can shed the virus in respiratory secretions. In contrast, we demonstrate that cottontail rabbits, fox squirrels, Wyoming ground squirrels, black-tailed prairie dogs, house mice, and racoons are not susceptible to SARS-CoV-2 infection. Our work expands upon the existing knowledge base of susceptible species and provides evidence that human-wildlife interactions could result in continued transmission of SARS-CoV-2.
