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...

UNLABELLED: Cysticercercosis is a parasitic infection that is commonly seen in developing countries. Treatment of cysticercosis can precipitate an intense inflammatory response which may further worsen the symptoms. Whole body MRI is an upcoming tool for screening of diseases. It can be acquired in the same setting as a brain MRI in reasonable time without any additional hardware. We present a case wherein whole body MRI was used to evaluate disseminated cysticercosis. It can prove as useful screening tool to gauge the disease load and modify the treatment plan accordingly, especially in endemic areas...

UNLABELLED: Cryptosporidium is a major cause of diarrheal illness mainly in children and immunocompromised adults. Disease severity ranges from asymptomatic or self-limited gastroenteritis to acute or chronic diarrhoea which may be associated with systemic features. Intracellular viruses that reside in many parasites have been incriminated in pathogenesis of diseases like trichomoniasis, leishmaniasis etc. Thus we attempted to detect and quantitate the intracellular viruses in Cryptosporidium isolates and sought to seek a relationship if any, with clinical features...
