N. caninum could cause abortion in small ruminants. The aim of the study was to detect N. caninum infection in ovine aborted foetuses in the Mashhad area by PCR examination. During the period 2009 to 2013, 71 ovine aborted foetuses were collected and their brain samples examined by PCR. Of the 71 brains of the aborted foetuses, N. caninum DNA was detected in seven (9.8%) samples. In conclusion, it seems that N. caninum may act as a causative agent of abortion in sheep in the Mashhad area.

Parasites of an invasive species, the raccoon dog (Nyctereutes procyonoides) from western Poland were investigated to clarify poorly known ecological key aspects of the species. The research was conducted in two study areas: the Ujście Warty National Park and the Bogdaniec Forestry District. Intestinal samples were collected from the intestinal tracks of 39 dead animals and 51 faecal samples were collected in all seasons from latrines of raccoon dogs. Macro-parasites, their eggs and protozoan parasites were investigated to assess the taxonomic composition of parasites, the level of infection and the risk of potential transfer of dangerous parasites from raccoon dogs to people and native species...

The aim of this study was to describe parasites of three lynx living in an enclosure of Western Pomeranian Nature Society in Jablonowo. During analysis of 3 gram faecal samples eggs of Toxascaris leonina, Toxocara cati, Ancylostoma sp. and oocysts of Cystoisospora felis were found. To our knowledge this is the first report of C. felis infection in lynx from Poland. Presented research show that wild cats in captivity are particularly exposed on parasitic infections and demand regular examination.

Ruminants often live in environments where the natural balance has been disturbed by humans. As a result, there is a transfer of parasitosis to domestic animals and sometimes humans. The aim of the study was to determine the annual species composition and level of gastrointestinal nematode infection of mouflon (Ovis aries musimon) from the half-open breeding colonizing areas of the Goleniowska Forest, and to assess the effectiveness of deworming. The course of the parasitic infection of mouflon depends largely on geoclimatic and breeding factors...

The purpose of this study was to detect piroplasms, which are pathogens of veterinary and zoonotic importance in ticks, that were collected from ponies and field vegetation and to determine the role of Shetland ponies as potential reservoir hosts for piroplasms. A total of 1737 feeding and 371 questing Ixodes ricinus collected from horses or vegetation were tested for the presence of Babesia and Theileria DNA. Piroplasm 18S rRNA gene amplification was conducted, and the obtained amplicons were sequenced. Babesia DNA was detected in only three ticks (one tick collected from a pony and two collected from vegetation), and all of the obtained sequences had 100% similarity to B...

Anna Okulewicz
Climate changes may influence the frequency, intensity and geographical distribution of parasites, directly affecting their dispersive stages in the environment (eggs, larvae) and, indirectly, the larvae living mainly in invertebrate intermediate hosts. In biologically diverse nematodes climate warming contributes to the increase in the range of distribution, colonization of new hosts and modification of their development cycles. This is particularly acute in the Arctic and pertains, for instance, to nematodes Ostertagia gruehneri and Setaria tundra parasitizing reindeer Rangifer tarandus and Umingmakstrongylus pallikuukensis in musk oxen (Ovibos moschatus)...

It is estimated that more than half of the nowadays known species are pathogenic parasites. Among macroparasites gastrointestinal nematodes are one of most common and having significant impact on life and health. Those organisms reveal strong, specific immune response in host, involving primary mechanisms associated with regulatory and Th2 cells. Referring to immunomodulatory abilities of helminths, parasite infections started to be considered as a possible therapy for many autoimmune diseases. Clinical trials on 2nd and 3rd stage are conducted in spite that treatment has not been recognized as safe for common use...

The protozoan Toxoplasma gondii is believed to be a common parasite of almost all endothermic animals and humans. However, recent reports of toxoplasmosis in marine mammals raise concern that cold-blooded animals may also be a potential source of T. gondii infection. The article discusses the presence of T. gondii in aquatic and terrestrial poikilothermic animals, which may be important elements in the transmission of the parasite.

Cryptosporidium is an opportunistic protozoan parasite that can cause severe diarrhoea in immunocompromised patients. The transmission of this pathogen in humans and animals is not fully understood. C. meleagridis, originally described in birds, is the only Cryptosporidium species known to naturally infect mammalian and avian species. This study documents the first detection of C. meleagridis in an HIV-infected woman in Poland.

Cryptosporidium parvum is a coccidian parasite which causes gastrointestinal disease in humans and a variety of other mammalian species. Several studies have reported different degrees of pathogenicity and virulence among Cryptosporidium species and isolates of the same species as well as evidence of variation in host susceptibility to infection. The study aimed to investigate infectivity and virulence of two Cryptosporidium parvum “Iowa isolate” (CpI) and a “local water isolate” (CpW). Thirty-three Swiss albino mice have been divided into three groups: Negative control Group (C), the CpI group infected with “Iowa isolate “and the CpW group infected with C...

Under natural conditions, Trypanosoma cruzi infection is transmitted to mammals when faeces contaminated with metacyclic trypomastigotes gain access through skin lesions, mucosa or bite wounds. Natural infection of bugs with T. cruzi can vary greatly from less than 1% up to 70%, depending on triatomine species: in the case of Triatoma dimidiata, the percentage of infection is around 30%. In this work uses biological fluids (saliva and faeces) from Triatoma dimidiata to inoculate experimental animals once or multiple times, before inoculation with faeces contaminated with metacyclic trypomastigotes discrete type unit Ia (TcI)...

The pathogenicity of fungi depends on, inter alia, the secretion of hydrolytic enzymes. The aim of this study was to determine the enzymatic activity of yeasts and yeast-like fungi isolated from children’s recreation areas, and compare the results with literature data of strains obtained from patients with mycoses. The enzymatic activity of 96 strains was assessed using an API ZYM kit (bioMerieux, France) and their biotypes were established. The fungal species were found to produce from 16 to 19 hydrolases: the most active were: leucine arylamidase (e5), acid phosphatase (e10), alkaline phosphatase (e1), naphthol-AS-BI-phosphohydrolase (e11), esterase – C4 (e2), β-galac - tosidase (e13) and β-glucosidase (e16)...

Toxoplasmosis is globally distributed, water- and food borne zoonosis caused by the single protozoan Toxoplasma gondii and probably one-third of the world’s human population is infected with this pathogen. Domestic and wild felids are definitive hosts of this pathogen and intermediate hosts for great variety of other homoeothermic animals. Human as other of the intermediate hosts may become infected in the main route of infection; it is the ingestion of parasite oocysts in contaminated water or soil and undercooked meat...

The organisms colonizing a living host create together with their host a holobiome. The holobioms are networks of mutualistic interactions between host`s cells and microorganisms communities. The fungi are among these microorganisms and have been also well known to infect human and animals. These organisms are associated with a wide range of diseases as superficial or systemic mycoses. Fungi as colonizers can also modify host physiology and metabolism, energy acquisition, vitamin-cofactor availability, development and function of immune system, and even host behavior...

Extracellular vesicles – EV’s, including exosomes, are known to be essential tools of intercellular communication, enabling the exchange of information without direct contact between cells. Exosomes are secreted both in vitro and in vivo by single- and multi-cellular organisms, regardless of their type, and play an essential role in cell-to-cell communication. EV’s may carry various materials and ongoing studies have provided a new insight into their potential participation in various critical biological processes, including carcinogenesis, protein trafficking, immunostimulation and pathogenesis of infectious diseases...

African swine fever (ASF) is a highly contagious viral disease of swine with a mortality rate approaching 100 percent. African Swine Fever Virus (ASFV) is a double-stranded DNA virus with a complex molecular structure. Its large genome, encoding multiple virulence factors, allows for efficient replication, which takes place predominantly in the cytoplasm of monocytes and macrophages. Also, ASFV has the ability to interfere with cell signalling pathways, which leads to various modulations in the synthesis profiles of interferon and other cytokines...
