Is there a place for xenodiagnosis in the clinic?
Expert Review of Anti-infective Therapy, 2014Whether Borrelia burgdorferi, the causative agent of Lyme disease, can persist after antibiotic therapy is an area of ongoing controversy. In animal models, B. burgdorferi DNA can be detected in tissues after antibiotic therapy as well as by using the natural tick vector to acquire the organism through feeding (xenodiagnosis).

A case report of Chagas disease in acute phase diagnosed by xenodiagnosis
Parasitology International, 2020Chagas disease is a serious problem of parasitic disease in the American continent, this zoonosis is caused by the flagellated protozoan known as Trypanosoma cruzi and transmitted through trypomastigotes present in the blood of sick hosts or in the faeces of the triatomines.

Skin reactions to bug bites as a result of xenodiagnosis
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1981Cutaneous allergic reactions to bites of two bug species Triatoma infestans and Dipetalogaster maxima, were studied in an area where T. infestans is the local domestic vector. While more delayed skin reactions occurred with the indigenous vector, reactions also occurred with D. maxima. Repeated exposure to D. maxima produced more intense immediate skin

A Modified Procedure of Xenodiagnosis for Chagas' Disease
The American Journal of Tropical Medicine and Hygiene, 1964Summary A modified procedure for the examination of reduviid bugs used in the xenodiagnosis of infection with Trypanosoma cruzi is described. It consists in the homogenization of a group of test insects in saline solution and the subsequent filtration, centrifugation and phase-contrast examination of the sediment for trypanosomes.

Xenodiagnosis Using Ixodes scapularis Larval Ticks in Humans
2017Xenodiagnosis is the use of a natural vector to detect the presence of an organism, and xenodiagnosis using Ixodes ticks has long been used by entomologists in Lyme disease research to provide evidence of the host's infectious status with Borrelia burgdorferi.

One of the main limitations for the effective control of canine leishmaniasis in endemic areas is the difficulty in identifying infectious dogs. The objective of this study was to determine factors, related to dogs and to parasite detection in sand flies, which are associated with the positive xenodiagnosis of Leishmania infantum using the vector ...

We detected Trypanosoma cruzi in blood samples of the wild rodent Octodon degus by xenodiagnosis and a polymerase chain reaction (PCR) using the domestic and wild vectors of Chagas disease, Triatoma infestans and Mepraia spinolai, respectively. We captured 35 rodents and extracted DNA from blood samples and intestinal contents of vectors fed on O ...
