“…Metamonada prefer low‐oxygen environments, either living free in anaerobic sediments or, more commonly, living inside animals as parasites or commensals (Adam, 2017; Kulda, Nohýnková & Čepička, 2017). They tend to have reduced mitochondria that lack genomes (hydrogenosomes or mitosomes) or lack mitochondria completely in the case of Monocercomonoides and relatives (Preaxostyla) (Karnkowska et al ., 2016; Hampl, 2017; Novák et al ., 2023).…”

“…One is the diplomonad Hexamita cryptocerci , which occurs in all three investigated Cryptocercus species. Other Hexamita species inhabit vertebrate or invertebrate hosts, sometimes as parasites, and one species is free‐living (Adam, 2017). The enigmatic small flagellate Prolophomonas tocopola , incertae sedis in Parabasalia, has been reported from C. punctulatus and C. clevelandi , but not from any other host, nor has it been verified by any other author (Cleveland et al ., 1934).…”

Protist symbionts of termites: diversity, distribution, and coevolution

The symbiosis between termites and their hindgut protists is mutually obligate and vertically inherited. It was established by the late Jurassic in the cockroach ancestors of termites as they transitioned to wood feeding. Since then, protist symbionts have been transmitted from host generation to host generation by proctodeal trophallaxis (anal feeding). The protists belong to multiple lineages within the eukaryotic superphylum Metamonada. Most of these lineages have evolved large cells with complex morphology, unlike the non‐termite‐associated Metamonada. The species richness and taxonomic composition of symbiotic protist communities varies widely across termite lineages, especially within the deep‐branching clade Teletisoptera. In general, closely related termites tend to harbour closely related protists, and deep‐branching termites tend to harbour deep‐branching protists, reflecting their broad‐scale co‐diversification. A closer view, however, reveals a complex distribution of protist lineages across hosts. Some protist taxa are common, some are rare, some are widespread, and some are restricted to a single host family or genus. Some protist taxa can be found in only a few, distantly related, host species. Thus, the long history of co‐diversification in this symbiosis has been complicated by lineage‐specific loss of symbionts, transfer of symbionts from one host lineage to another, and by independent diversification of the symbionts relative to their hosts. This review aims to introduce the biology of this important symbiosis and serve as a gateway to the diversity and systematics literature for both termites and protists. A searchable database with all termite‐protist occurrence records and taxonomic references is provided as a supplementary file to encourage and facilitate new research in this field.

This study presents the first case in Poland of isolation and molecular identification of the Spironucleus vortens parasite from the digestive tract of diseased ornamental fish belonging to the species discus fish (Symphysodon discus Heckel, 1840). Recently, an increasing percentage of fish submitted for testing to the Department of Biology and Fish Diseases, have been observed that show typical symptoms of hole‐in‐the‐head disease, therefore it is important to have accurate information about this disease. In preparation of this work, two fish were studied. The polymerase chain reaction (PCR) used a pair of primers designed specifically for this experiment. The amplification product was sequenced and the partial sequence of small ribosomal subunit (18S rRNA) was deposited in the GenBank database. The obtained nucleotide sequence showed a high percentage of identity with the compared sequence of the S. vortens reference strain (98.52%). Additionally, the presence of potentially dangerous bacteria belonging to four species, namely Citrobacter braakii, Acinetobacter lwoffi, Pseudomonas putida and Comamonas testosteroni was confirmed in the material collected from the tested fish. Bacterial isolates were examined biochemically. An antibiotic susceptibility testing showed that in three of the four isolates there appeared resistance to the drugs used.Trial Registration: Clinical trial registration was not required for this study.

Giardia duodenalis: Biology and Pathogenesis

Giardia duodenalis captured the attention of Leeuwenhoek in 1681 while he was examining his own diarrheal stool, but, ironically, it did not really gain attention as a human pathogen until the 1960s, when outbreaks were reported. Key technological advances, including in vitro cultivation, genomic and proteomic databases, and advances in microscopic and molecular approaches, have led to understand that this is a eukaryotic organism with a reduced genome rather than a truly premitochondriate eukaryote.
