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.

Effect of fasting on the composition of the fat body lipid of Dipetalogaster maximus , Triatoma infestans and Panstrongylus megistus (Hemiptera: Reduviidae)

Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1998
Modifications in content and lipid composition induced by fasting were examined in fat bodies from adults of Triatominae, Dipetalogaster maximus, Triatoma infestans and Panstrongylus megistus. With fasting, total lipid stores dropped approximately 50% for T. infestans and more than 70% for P. megistus. Total lipids analyzed by thin layer chromatography

Growth and Development of Two Trypanosoma Cruzi Clones in the Arthropod Dipetalogaster Maximus

The American Journal of Tropical Medicine and Hygiene, 1982
Trypomastigotes of single-cell-isolate Trypanosoma cruzi clones WA-250/1 and Esmereldo/2 were used to infect third-instar Dipetalogaster maximus. The level of infection was directly proportional to the concentration of trypomastigotes present in the blood meal. The minimum infectious dose for D. maximus was calculated as 5 organisms/ml.

Biochemical Characterization of a Thrombin Inhibitor from the Bloodsucking Bug <i>Dipetalogaster maximus</i>

Pathophysiology of Haemostasis and Thrombosis, 1999
From the bloodsucking bug <i>Dipetalogaster maximus</i>, a protein with anticoagulant activity was isolated and biochemically characterized. The isolated protein, named dipetalogastin, possesses an average molecular mass of 11.8 kD. Its N-terminal sequence shows homology to rhodniin, a thrombin inhibitor isolated from the bug <i> ...

Effects of Temperature and pH on Hexokinase from the Flight Muscles of <I>Dipetalogaster maximus</I> (Hemiptera: Reduviidae) [PDF]

Journal of Medical Entomology, 2000
Effects of temperature and pH on the catalytic properties of hexokinase (HK, EC 2.7.1.1) from the flight muscles of Dipetalogaster maximus (Uhler) were studied. The enzyme showed a hyperbolic behavior with its two substrates (glucose and ATP). There was no inhibition by glucose. Apparent Km and Vmax increased as pH increased from 7.0 to 8.5.

Dipetalogaster maximus (Hemiptera, Triatominae) for xenodiagnosis of patients with serologically detectable Trypanosoma cruzi infection

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1979
In patients serologically positive for Trypanosoma cruzi infection the three bug species/instar combinations used in xenodiagnosis showed third-instar Dipetalogaster maximus to be more efficient in detecting circulating trypanosomes than the first instar of the same species which, in turn, is more sensitive than third-instar Triatoma infestans.

Abdominal stretch reception in Dipetalogaster maximus (Hemiptera: Reduviidae)

Journal of Insect Physiology, 1984
Abstract Each half abdominal segment in 5th-instar larvae of the giant bloodsucking reduviid, Dipetalogaster maximus, contains 3 stretch receptor neurones, one associated with the tergosternal muscles, one with the ventral intersegmental muscles and one with the dorsal intersegmental muscles.

Epizootiology Of Trypanosoma Cruzi In Southwestern North America Part X: The Biosystematics of Dipetalogaster maximus in Mexico1 (Hemiptera: Reduviidae) (Kinetoplastida: Trypanosomidae)

Journal of Medical Entomology, 1967
A review of the literature of Dipetalogaster maximus was made concerning the ecology, distribution, systematics and infection rates with Trypanosoma Cruzi . New information is given concerning the ecology, life history, hybridizations, and laboratory infections of this large kissing bug. Dipetalogaster maximus has been found to inhabit the crevices in

Non-invasive blood sampling from primates using laboratory-bred blood-sucking bugs (Dipetalogaster maximus; Reduviidae, Heteroptera)

Primates, 2006
Primates are easily stressed by the conventional veterinary blood sampling routine and consequently, measured blood parameters may be biased. In this study, we tested blood-sucking bugs (Dipetalogaster maximus) on one lemur and two ape species (Microcebus murinus, Pongo abelii, Pan paniscus) as an alternative, non-invasive technique for bleeding ...
