Rodents are recognized as reservoirs for , playing a crucial role in maintaining the parasite's presence in the environment. Biomonitoring was conducted to assess the role of sylvatic rodents in maintaining , and to analyse the prevalence and seroprevalence of the parasite in seven wild rodent species. Rodents were collected in an open grassland study site located in northeastern Poland, and dissected.

Article Synopsis
  • Eucoleus aerophilus is a parasite affecting carnivores and occasionally humans, found in 38 countries worldwide.
  • A study in Central Europe examined 342 red fox fecal samples for the prevalence of this parasite using PCR methods and found E. aerophilus DNA in 230 samples.
  • The research identified 22 genetic variations of E. aerophilus and highlighted the high prevalence of Capillariidae eggs, along with other parasite eggs in the samples, marking it as the first molecular analysis of E. aerophilus in Poland.

Background: Biomonitoring is an essential activity for identifying possible vectors and reservoirs of pathogens and predicting potential outbreaks. Wild red foxes are present in both sylvatic and synanthropic environments, making them potential carriers of zoonotic pathogens. Experimental studies have shown that both coyotes and red foxes can transmit SARS-CoV-2.

Article Synopsis
  • Alveolar echinococcosis is a severe disease caused by a parasitic cestode that affects humans, who unintentionally ingest its eggs through contaminated food or contact with infected animals.
  • A study conducted in north-eastern Poland found Asian genetic components in tapeworms from local echinococcosis patients, indicating a possible new link between these parasites and human infections.
  • The research suggests that red foxes are a primary source of this contamination, and the presence of Asian genetic variants may extend to human populations in other regions where these foxes are found.

Article Synopsis
  • A 24-year-old man from Zimbabwe living in Poland experienced abdominal pain, fatigue, and gastrointestinal issues for 3 years, leading to extensive diagnostic testing.
  • Tests confirmed he had chronic intestinal schistosomiasis caused by co-infections of Schistosoma intercalatum and Schistosoma mansoni.
  • After undergoing two treatment cycles with praziquantel, the patient improved, highlighting the need to recognize rare tropical diseases in individuals from high-endemic regions living abroad.

Article Synopsis
  • * Researchers collected 214 water samples from different sites, including wastewater treatment plants, a slaughterhouse, and rivers, and used advanced techniques like real-time PCR for analysis.
  • * They found T. gondii DNA in 1.9% of the samples, indicating moderate levels of contamination, which suggests potential links to infections in humans and animals in the area.

Introduction: Malaria remains a diagnostic and therapeutic challenge in many endemic regions of sub-Saharan Africa. It is one of the most important causes of morbidity and mortality, especially in children <5 years. is responsible for the majority of severe malaria cases in sub-Saharan Africa, but is not the exclusive one.

According to the World Health Organization 94% of global malaria cases and 94% of global malaria deaths have been reported from Africa. Unfortunately, it is difficult to determine the exact prevalence of disease in some African countries due to a large number of asymptomatic cases. The aim of this study was to assess the prevalence of malaria infections in seemingly healthy children living in the Central African Republic (CAR).

Echinococcus multilocularis is a parasite that causes a dangerous zoonosis, alveolar echinococcosis (AE). Its presence in water sources, however, has scarcely been studied heretofore. Accordingly, 222 samples of different origin including wastewater from wastewater treatment plants (WWTPs) (n = 137), slaughterhouse (n = 49) as well as water from rivers (n = 26) and a cattle farm (n = 10) were collected from Xining City and a rural area in Qinghai-Tibet Plateau (QTP), an endemic area.

  • Toxoplasma gondii infections are rising in China, but little is known about its presence in vegetables sold for consumption.
  • A study in Xining City analyzed 279 fresh vegetable samples using advanced genetic testing, finding T. gondii DNA in 10 (3.6%) of them, predominantly type I.
  • The study demonstrates that fresh vegetables in Qinghai province can be contaminated with T. gondii, highlighting potential health risks for consumers who eat them raw or unwashed.

Water is one of the possible transmission routes for water- and foodborne parasites to humans. Echinococcus multilocularis is a parasite, which causes alveolar echinococcosis (AE). Nevertheless, no environmental studies have been performed as yet to confirm the occurrence of E.

The CRISPR/Cas9 system, a natural defence system of bacterial organisms, has recently been used to modify genomes of the most important protozoa parasites. Successful genome manipulations with the CRISPR/Cas9 system are changing the present view of genetics in parasitology. The application of this system offers a major chance to overcome the current restriction in culturing, maintaining and analysing protozoan parasites, and allows dynamic analysis of parasite genes functions, leading to a better understanding of pathogenesis.

Giardia intestinalis is a protozoan parasite, transmitted to humans and animals by the faecal-oral route, mainly through contaminated water and food. Knowledge about the distribution of this parasite in surface water in Poland is fragmentary and incomplete. Accordingly, 36 environmental water samples taken from surface water reservoirs and wells were collected in Pomerania and Warmia-Masuria provinces, Poland.

Toxoplasma gondii infections are acquired through the ingestion of oocysts present in the environment. However, there is no data about their occurrence in the air or about airborne transmission of these infections. In the present paper, we report on the identification of T.

It is estimated that faecal-orally transmitted diseases are common in Afghanistan, as a consequence of poor hygienic standards of life and widespread contamination of water and food with both human and animal faeces. However, there is little information in the literature concerning infections caused by intestinal parasites in the Afghan population. In this study, we report the occurrence of Giardia intestinalis assemblages (A and B) in formalin-fixed stool samples collected from 245 Afghan schoolchildren living in Ghazni Province in eastern Afghanistan.

Echinococcus multilocularis is a tapeworm that may cause alveolar echinococcosis (AE), one of the most dangerous parasitic zoonoses. As in the case of some foodborne diseases, unwashed fruits and vegetables contaminated with eggs of E. multilocularis may serve as an important transmission route for this parasite.

Various species of amoebas belonging to the genus Acanthamoeba are widely distributed in many parts of the world. Some strains of these protozoans may exist as parasites and pose risks to human health as causative agents of serious human diseases. Currently in China there is a lack of information about the distribution of Acanthamoeba strains in the environment.

Objectives: The Afghans, living in poor socioeconomic conditions, are estimated to be a community with a high rate of intestinal parasitic infections. The aim of the study was to estimate the prevalence and species of intestinal parasites among children's population in eastern Afghanistan and to present the methods of optimizing the techniques for identification of pathogens in light microscopy. The research was carried out as a part of humanitarian project Capacity building of health care system in Ghazni Province.

Background: Members of the Polish Military Contingent (PMC) have been stationed in Afghanistan since 2002. They typically serve in areas characterised by low standards of sanitation which often leads to the development of food- and waterborne diseases. The aim of the study was to evaluate the prevalence of Giardia intestinalis infections among Polish soldiers deployed to Afghanistan.

Objective: To estimate the prevalence of intestinal parasites and their species in Afghan school children and to establish appropriate treatment methods for detected pathogens.

Methods: Parasitological examination of stool samples collected from 1369 children aged 8-18, students of the Jahan Malika High School in Ghazni Province in eastern Afghanistan, was conducted in the period November 2013-April 2014. Three stool samples were collected from each patient every second day; the samples were fixed in 10% formalin and tested by light microscopy using the methods of direct smear in Lugol's solution, decantation in distilled water, and Fülleborn's flotation.
