Feeding of ticks on animals for transmission and xenodiagnosis in Lyme disease research. [PDF]
Journal of Visualized Experiments, 2013 Transmission of the etiologic agent of Lyme disease, Borrelia burgdorferi, occurs by the attachment and blood feeding of Ixodes species ticks on mammalian hosts.

Xenodiagnosis to detect Borrelia burgdorferi infection: a first-in-human study. [PDF]
Clinical Infectious Diseases, 2014 BACKGROUND Animal studies suggest that Borrelia burgdorferi, the agent of Lyme disease, may persist after antibiotic therapy and can be detected by various means including xenodiagnosis using the natural tick vector (Ixodes scapularis).

Xenodiagnosis for posttreatment Lyme disease syndrome: resolving the conundrum or adding to it? [PDF]
Clinical Infectious Diseases, 2014 The first reports of Lyme disease in Connecticut in the mid-1970s, followed by the discovery of its tick-borne etiologic agent, Borrelia burgdorferi, in 1983, has spawned one of the longest controversies in the history of biomedical research [1]. Whereas

Trypanosoma cruzi parasitemia observed in immunocompromised patients: the importance of the artificial xenodiagnosis [PDF]
Revista do Instituto de Medicina Tropical de São Paulo, 2001 Trypanosoma cruzi parasitemia observed in immunocompromised patients (transplant or positive HIV) occurred more frequently by the artificial xenodiagnosis method (10/38) compared with hemoculture (2/38), given the same quantity of blood.

Studies in search of a suitable experimental insect model for xenodiagnosis of hosts with Chagas' disease. 1--Comparative xenodiagnosis with nine Triatomine species of animals with acute infections by Trypanosoma cruzi. [PDF]
Memórias do Instituto Oswaldo Cruz, 1982 In search of a suitable vector species for xenodiagnosis of humans and animals with chronic Chagas' disease we first investigated the reactions of different vector species to acute infection with Trypanosoma cruzi.

Chronic Chagas disease: PCR-xenodiagnosis without previous microscopic observation is a useful tool to detect viable Trypanosoma cruzi [PDF]
Biological Research, 2013 We evaluate the elimination of the microscopic stage of conventional xenodiagnosis (XD) to optimize the parasitological diagnosis of Trypanosoma cruzi in chronic Chagas disease.

Absence of both circadian rhythm and Trypanosoma cruzi periodicity with xenodiagnosis in chronic chagasic individuals Ausência de ritmo circadiano e de periodicidade do Trypanosoma cruzi ao xenodiagnóstico em chagásicos crônicos [PDF]
Revista da Sociedade Brasileira de Medicina Tropical, 2000 Xenodiagnoses were performed every 3 hours using 10 Triatoma infestans 3rd instar for 24 to 72 hours, in 18 chronic chagasics with positive serology and/or xenodiagnosis.

Real-Time PCR in faecal samples of Triatoma infestans obtained by xenodiagnosis: proposal for an exogenous internal control [PDF]
Parasites & Vectors, 2012 The polymerase chain reaction (PCR) has proved to be a sensitive technique to detect Trypanosoma cruzi in the chronic phase of Chagas disease, which is characterized by low and fluctuating parasitemia.
