  • Insufficient knowledge regarding the host range and specificity of many parasitic chytrid species, particularly Rhizophydium algavorum and other obligate algal parasites.

    Drivers of aquatic zoosporic parasites in natural and artificial environments · 2026 · DOI

  • Whole-genome sequencing tracing at cervid-livestock-human interfaces. Expanded monitoring of species with small sample sizes but high infection rates.

    The role of cervids in the transmission of Blastocystis spp. to livestock and humans: a comprehensive review · 2026 · DOI

  • The lack of effective treatment for cryptosporidiosis. The limited understanding of the genomic heterogeneity of Cryptosporidium and its relation to drug resistance.

    Genomic heterogeneity of NAD(P)H dehydrogenase predisposes Cryptosporidium to clofazimine resistance · 2026 · DOI

  • The study is limited to a single case report. PCR-based testing for Cryptosporidium was not available in the institution.

    CRYPTOSPORIDIUM PARVUM COLITIS IN A PEDIATRIC LIVER TRANSPLANT RECIPIENT: A CASE REPORT · 2026 · DOI

  • There is a limited literature on cryptosporidiosis in pediatric liver transplant recipients. The diagnosis of Cryptosporidium infection in immunosuppressed patients can be challenging.

    CRYPTOSPORIDIUM PARVUM COLITIS IN A PEDIATRIC LIVER TRANSPLANT RECIPIENT: A CASE REPORT · 2026 · DOI

  • The host-parasite interface is complex and difficult to study. Effective treatments for cryptosporidiosis are lacking. The disease is life-threatening in immunocompromised patients and children.

    Cryptosporidium secreted proteins form a complex layered interface with the host cell · 2026 · DOI

  • Further study of the host-parasite interface is needed. The development of new methods for studying the host-parasite interface is necessary. The application of ultrastructure expansion microscopy to other parasites could be explored.

    Cryptosporidium secreted proteins form a complex layered interface with the host cell · 2026 · DOI

  • The study only investigated the prevalence of cryptosporidiosis in cattle raised by nomadic communities in Southern Punjab, Pakistan. The sample size was limited to 184 cattle.

    Status of cryptosporidiosis in cattle raised by marginalized nomadic communities of Southern Punjab, Pakistan: an observational study · 2026 · DOI

  • The study does not provide a comprehensive understanding of the pathogenicity and modes of transmission of Blastocystis spp.. The study is limited to a retrospective analysis of stool reports from a single medical center in central Taiwan.

    Epidemiology and clinical characteristics of intestinal parasites among patients of a medical center in central Taiwan: a retrospective study of Blastocystis infection · 2026 · DOI

  • The pathogenicity and modes of transmission of Blastocystis spp. remain incompletely understood. There is a need for further research on the epidemiology and clinical characteristics of intestinal parasites in Taiwan.

    Epidemiology and clinical characteristics of intestinal parasites among patients of a medical center in central Taiwan: a retrospective study of Blastocystis infection · 2026 · DOI

  • Surveillance systems for human and animal health operate largely in parallel, with minimal data integration. Environmental monitoring for protozoan contamination in surface water and abattoir discharge remains sporadic. Laboratory capacity for species-level identification is concentrated in a small number of research institutions.
