Isolation of Crithidia spp. from lesions of immunocompetent patients with suspected cutaneous leishmaniasis in Iran [PDF]
Tropical Medicine & International Health, 2018 SummaryObjectiveLeishmania major has been considered as the main aetiological agent of cutaneous leishmaniasis in Iran. However, there are recent reports about the existence of Crithidia spp in cutaneous lesions in southern Iran. Therefore, this study was designed to decipher some morphological, biological and molecular aspects of this phenomenon ...

Pollen from multiple sunflower cultivars and species reduces a common bumblebee gut pathogen [PDF]
Royal Society Open Science, 2019 Pathogens are one of the factors driving pollinator declines. Diet can play an important role in mediating pollinator health and resistance to pathogens. Sunflower pollen (Helianthus annuus) dramatically reduced a gut pathogen (Crithidia bombi) of Bombus

How Population Structure and Nest Membership Shape Pathogen Patterns in Bumble Bees. [PDF]
Mol EcolABSTRACT Host density, genetic diversity and social groups are key factors influencing pathogen transmission in wildlife populations, but their interactions remain poorly understood in insects. Islands can provide natural laboratories with distinct populations that vary in density and genetic diversity, whereby dense, genetically homogeneous ...

Sex, horizontal transmission, and multiple hosts prevent local adaptation of Crithidia bombi, a parasite of bumblebees (Bombus spp.) [PDF]
Ecology and Evolution, 2012 AbstractLocal adaptation within host‐parasite systems can evolve by several non‐exclusive drivers (e.g., host species‐genetic adaptation; ecological conditions‐ecological adaptation, and time‐temporal adaptation). Social insects, especially bumblebees, with an annual colony life history not only provide an ideal system to test parasite transmission ...

Monophyletic origin of beta-division proteobacterial endosymbionts and their coevolution with insect trypanosomatid protozoa Blastocrithidia culicis and Crithidia spp. [PDF]
Proceedings of the National Academy of Sciences, 1994 Some trypanosomatid protozoa (order Kinetoplastida) are well known to harbor bacterial endosymbionts. Their phylogenetic positions and evolutionary relationships with the hosts were deduced by comparing the rRNA gene sequences. Earlier, we observed that these symbionts from three Crithidia spp.

A Stroll Through the History of Monoxenous Trypanosomatids Infection in Vertebrate Hosts
Frontiers in Cellular and Infection Microbiology, 2022 The Trypanosomatidae family encompasses unicellular flagellates and obligate parasites of invertebrates, vertebrates, and plants. Trypanosomatids are traditionally divided into heteroxenous, characterized by the alternation of the life cycle between an ...

Molecular Identification of Species Caused Cutaneous Leishmaniasis in South-ern Zone of Iran
Journal of Arthropod-Borne Diseases, 2018 Background: Leishmania major and Leishmania tropica are two main species causing cutaneous leishmaniasis (CL) in Iran. Recently, Crithidia spp. has also been reported in the wound of patients with CL.

A draft genome of the honey bee trypanosomatid parasite Crithidia mellificae. [PDF]
PLoS ONE, 2014 Since 2006, honey bee colonies in North America and Europe have experienced increased annual mortality. These losses correlate with increased pathogen incidence and abundance, though no single etiologic agent has been identified.
