Xenodiagnosis Using Ixodes scapularis Larval Ticks in Humans

2017
Xenodiagnosis 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.

Skin reactions to bug bites as a result of xenodiagnosis

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1981
Cutaneous 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 case report of Chagas disease in acute phase diagnosed by xenodiagnosis

Parasitology International, 2020

A Modified Procedure of Xenodiagnosis for Chagas' Disease

The American Journal of Tropical Medicine and Hygiene, 1964
Summary 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.

Is there a place for xenodiagnosis in the clinic?

Expert Review of Anti-infective Therapy, 2014
Whether 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).

Improvements in Routine Xenodiagnosis with First Instar Dipetalogaster Maximus (Uhler 1894) (Triatominae)

The American Journal of Tropical Medicine and Hygiene, 1979
First instar Dipetalogaster maximus proved as effective as third instar Triatoma infestans in detecting circulating Trypanosoma cruzi in patients with chronic infections examined in a routine xenodiagnostic laboratory. Since rearing costs are diminished, D. maximus has now replaced T. infestans as the xenodiagnostic agent in our laboratory.

[Chagasic heart disease in Mexico. 1st case diagnosed by positive xenodiagnosis].

Archivos del Instituto de Cardiologia de Mexico, 1985
We describe the first case of chronic Chagas heart disease in México, in whom the illness was corroborated by means of the "xenodiagnosis". The patient had changing bundle branch block and also A-V block that required insertion of a pacemaker. This disease is seldom seen in Mexico.
