The nematode Mastophorus muris caused castration of male Ceratophyllus laeviceps. The castrates made up an average of 15.5% of the collections. In other reports from the USSR, more than 50% were castrates. Helminths including roundworms and tapeworms are also reported to cause castration in fleas. Amonkar, S. V. & Munshi, D. M. (1965). On the presence of leptomonads in the digestive tract of the Indian rat flea Xenopsylla cheopis (Roths). J. Anim. Morphol. Physiol., 12(1): 32-41. The appearance of various forms of leptomonads in the rat flea are described. The leptomonads are morphologically indistinguishable from Leptomonas ctenocephali described from dog fleas. The dialaled pyloric region of the ileum of infected fleas is found to be practically blocked by a large number of these flagellates. Beaucournu, J.-C. & Chabaud, A. -G. (1963). Infestation spontan6e de puces par le spiruride Mastophorus muris (Gmelin). Ann. Parasitol. Hum. Comp., 38: 931-934. The flea Ctenophthalmus avernus, collected in France was found to be infected by M. muris. The nematode was also found in field mice which were hosts to the fleas. Although this nematode has been experimentally transferred to insect hosts, it has been rarely found infecting insects in nature. Jenkins, D. W. (1964).

Abstract: Trypanosomatids are easy to cultivate and they are (in many cases) amenable to genetic manipulation. Genome sequencing has become a standard tool routinely used in the study of these flagellates. In this review, we summarize the current state of the field and our vision of what needs to be done in order to achieve a more comprehensive picture of trypanosomatid evolution. This will also help to illuminate the lineage-specific proteins and pathways, which can be used as potential targets in treating diseases caused by these parasites.

  • AQPX-Cluster Aquaporins and Aquaglyceroporins Are
    ARTICLE https://doi.org/10.1038/s42003-021-02472-9 OPEN AQPX-cluster aquaporins and aquaglyceroporins are asymmetrically distributed in trypanosomes ✉ ✉ Fiorella Carla Tesan 1,2, Ramiro Lorenzo 3, Karina Alleva 1,2,4 & Ana Romina Fox 3,4 Major Intrinsic Proteins (MIPs) are membrane channels that permeate water and other small solutes. Some trypanosomatid MIPs mediate the uptake of antiparasitic compounds, placing them as potential drug targets. However, a thorough study of the diversity of these channels is still missing. Here we place trypanosomatid channels in the sequence-function space of the large MIP superfamily through a sequence similarity network. This analysis exposes that trypanosomatid aquaporins integrate a distant cluster from the currently defined MIP 1234567890():,; families, here named aquaporin X (AQPX). Our phylogenetic analyses reveal that trypano- somatid MIPs distribute exclusively between aquaglyceroporin (GLP) and AQPX, being the AQPX family expanded in the Metakinetoplastina common ancestor before the origin of the parasitic order Trypanosomatida. Synteny analysis shows how African trypanosomes spe- cifically lost AQPXs, whereas American trypanosomes specifically lost GLPs. AQPXs diverge from already described MIPs on crucial residues. Together, our results expose the diversity of trypanosomatid MIPs and will aid further functional, structural, and physiological research needed to face the potentiality of the AQPXs as gateways for trypanocidal drugs. 1 Universidad de Buenos Aires, Facultad de Farmacia y Bioquímica, Departamento de Fisicomatemática, Cátedra de Física, Buenos Aires, Argentina. 2 CONICET-Universidad de Buenos Aires, Instituto de Química y Fisicoquímica Biológicas (IQUIFIB), Buenos Aires, Argentina. 3 Laboratorio de Farmacología, Centro de Investigación Veterinaria de Tandil (CIVETAN), (CONICET-CICPBA-UNCPBA) Facultad de Ciencias Veterinarias, Universidad Nacional del Centro ✉ de la Provincia de Buenos Aires, Tandil, Argentina.

E- mail: [email protected] SUMMARY A flagellate isolated from the intestinal tract of a reduviid bug Ricolla simillima (Heteroptera) in Costa Rica was found to represent a new trypanosomatid species by the phylogenetic analysis of small subunit ribosomal RNA (SSU rRNA), glyceraldehyde phosphate dehydrogenase (GAPDH) and large subunit of RNA polymerase II (RPOIILS) genes. The phylogenetic position of this trypanosomatid, together with its typical promastigote morphology and the host identity, allowed classifying it as a species that belong to the polyphyletic genus Leptomonas. Interestingly, the new species was revealed as a member of the novel phylogenetic clade representing the closest known relative of Leishmania. With the new species used as an outgroup to root the Leishmania RPOIILS phylogenetic tree, the lineage of the Neotropical species L. enriettii was found branching off early during the evolution of this genus.

Brasil 4365, 21045-900 Rio de Janeiro, RJ, Brasil *Departamento de Ciências Biológicas, Escola Nacional de Saúde Pública, Fiocruz, Rio de Janeiro, RJ, Brasil An HIV positive patient presenting a clinical picture of visceral leishmaniasis co-infection was sub- mitted to a bone marrow aspiration after admission to hospital. Amastigotes forms were seen in the bone marrow aspirate and the parasite grew in culture as promastigotes. Molecular analyses showed that the flagellates isolated did not belong to the genera Leishmania, Trypanosoma or Sauroleishmania. It was not possible to establish infection in laboratory animals. In vitro culture of mouse peritoneal macroph- ages revealed the invasion of the host cells by the flagellates and their killing 48 hr after infection. Opportunistic infection with an insect trypanosomatid was suspected. Further hybridization analyses against a pannel of different monoxenous and heteroxenous trypanosomatids showed kDNA cross-ho- mology with Leptomonas pulexsimulantis a trypanosomatid found in the dog’s flea.

It was found parasitising the alimentary tract of the insect host Cyrtomenus bergi, a polyphagous pest. The morphology of B. cyrtomeni was investigated using light and transmission microscopy and molecular phylogeny was inferred from the sequences of spliced leader RNA (SL rRNA) - 5S rRNA gene repeats and the 18S small subunit (SSU) rRNA gene. Epimastigotes of variable size with straphanger cysts adhering to the middle of the flagellum were observed in the intestinal tract, hemolymph and Malpighian tubules. Kinetoplasts were always observed anterior to the nucleus. The ultrastructure of longitudinal sections of epimastigotes showed the flagellum arising laterally from a relatively shallow flagellar pocket near the kinetoplast. SL RNA and 5S rRNA gene repeats were positive in all cases, producing a 0.8-kb band. The amplicons were 797-803 bp long with > 98.5% identity, indicating that they originated from the same organism.

Some of them are causative agents of canine vector-borne diseases. Their diagnosis is often missing in a gold standard. Here, we proposed a molecular approach for the diagnosis and study of Kinetoplastida. The TaqMan qPCR assays target the following genes: 24Sa LSU of Kinetoplastida, 28S LSU of Leishmania/ Trypanosoma spp., 5.8S rRNA of Trypanosoma spp., 18S SSU of Leishmania spp., kinetoplast minicircle DNA (kDNA) of L. donovani complex and kDNA of L. infantum, were designed, validated for their sensitivity (Se) and specificity (Sp) in silico and in vitro using a panel of known DNAs. They were then used to screen 369 blood samples (358 dogs, 2 equids, 9 monkeys). In addition, new 28S LSU primer sets are presented to use for Kinetoplastida’s identification by PCR/sequencing.

High-pressure freezing and Bernhard’s EDtA regressive staining, used for the first time for monoxenous (one host) trypanosomatids, revealed the presence of viral particles with cytosolic localization in one and unique mitochondrial localization in another species. in accord- ance with previous observations, our results emphasize a discrepancy between morphology and molecular taxonomy of the family trypanosomatidae.

  • Observations on Leptomonas Ctenocephali (Fantham, 1912)
    495 TRANSACTIONSOF THE ROYAL SO~UErYOF TROPIC&L MEDICINE AND HYGIENE. Vol. 40. No. 4. March, 1947. OBSERVATIONS ON LEPTOMONAS CTENOCEPHALI (FANTHAM, 1912). BY ALFRED J. GIBBS.* Downloaded from https://academic.oup.com/trstmh/article/40/4/495/1936312 by guest on 29 September 2021 "ITae parasite was discovered in the dog flea, Ctenocephalus canis, by BAsllm (1910), who believed he was dealing with a species of Leishmania. FmTXtAM (1912) placed it in genus Her#etomonas, and provisionally gave it the specific name Ctenocephali. Since, however, crithidia and trypanosomes are not found at any stage, it was later transferred to the genus Leptoraonas. DgVELOPMENT IN LARVA. Infection of the flea takes place during the larval stage, and is the result, as will be shown, of the ingestion of resistant bodies of l~ishmm~ia form which are present in the faeces of infected fleas. The faeces consists chiefly of partially digested blood which can hc dissolved in saline under a cover-glass for the study of the bodies in the living state. They are spherical and without apparent internal detail. When fixed and stained by Leishman's method they are ovoid in form and measure some 3 /~ by 2"2 /~. The nucleus and kinetoplast are situated near one end, while the rhizoplast extends from the region of the kinetoplast to the opposite end of the body. No cyst wall can be seen either when stained or examined in the fresh state in saline. (Fig. 1, p. 497.) Larvae feed readily on the faeces of the flea, which, when dry, is found in tho form of granules on the body of the dog.
