Primary cutaneous amoebiasis is rare, and typically affects immunocompromised patients and presents with unique clinical and histopathologic changes. Untreated, the infection could progress to involve the central nervous system, which is almost universally fatal. We present a case of primary cutaneous acanthamoebiasis in a patient with chronic lymphocytic leukemia on acalabrutinib.

Blastocystis is an intestinal microeukaryote that has raised attention due to its wide distribution in animals and humans. The risk of zoonotic circulation primarily arises from close contact with infected animals. Therefore, the following study aimed to evaluate the diversity and frequency of Blastocystis subtypes in Colombian human and animal samples using complete sequencing of the 18S rRNA gene.

Background: Blastocystis is one of the most common eukaryotic microorganisms colonizing the intestines of both humans and animals, but the conditions under which it may be a pathogen are unclear.
Methods: To study the genomic characteristics of circulating subtypes (ST) in Colombia, we established nine xenic cultures from Blastocystis isolated from human fecal samples, we identified 10 different subtypes, since one sample had a mixed infection. Thus, the genomes of the subtypes ST1 (n = 3), ST2 (n = 1), ST3 (n = 2), ST6 (n = 1), ST7 (n = 1), and ST8 (n = 2) were sequenced using Illumina and Oxford Nanopore Technologies (ONT).

Purpose: Blastocystis species are widely distributed micro-eukaryote parasites found in both human and nonhuman primates. Despite having a global distribution, descriptions of Blastocystis subtype diversity in neotropical primates is largely limited to captive animals. The aim of this study was to molecularly characterize the presence of Blastocystis in free-ranging black-headed night monkeys, Aotus nigriceps, and to analyze Blastocystis heterogeneity in primates of the Parvorder Platyrrhini.
