The primary and secondary structure of the internal transcribed spacers ribosomal DNA (ITS1 ITS2) their utility for phylogenetic analysis closely related species were examined using Anopheles gambiae complex as a model. Restriction mapping revealed an unusual architectural feature in ITS1 several members An. cryptic complex. Multiple spacer lengths are prevalent merus melas due to variable numbers repeated 250 bp sequence. Secondary indicated that repeat forms helix loop may be involved rDNA...
Chagas disease is an anthropozoonosis caused by the protozoan parasite Trypanosoma cruzi that represents a major public health problem in Latin America. Although United States defined as non-endemic for due to rarity of human cases, presence T. has now been amply demonstrated enzootic different regions south country from Georgia California. In southeastern Louisiana, high infection rate Triatoma sanguisuga, local vector this area. However, little known about role small mammals wild and...
This review examines the advancements and methodologies of artificial feeding systems for study vector-borne diseases, offering a critical assessment their development, advantages, limitations relative to traditional live host models. It underscores ethical considerations practical benefits such systems, including minimizing use animals enhancing experimental consistency. Various techniques are detailed, membrane feeding, capillary utilization engineered biocompatible materials, with...
Though a variety of methods are used to conduct West Nile virus (WNV) surveillance, accurate prediction and prevention outbreaks remains global challenge. Previous studies have established that the concentration antibodies mosquito saliva is directly related intensity exposure bites can be good proxy determine risk infection in human populations. To assess characteristics transmission dynamics among avian communities, we tested levels IgY against whole salivary glands Aedes albopictus Culex...
After Hurricane Katrina, the number of reported cases West Nile neuroinvasive disease (WNND) sharply increased in hurricane-affected regions Louisiana and Mississippi. In 2006, a >2-fold increase WNND incidence was observed areas than previous years.
Trypanosoma cruzi has been divided into Discrete Typing Units I and non-I (II-VI). T. is predominant in Mexico Central America, while most of South including Argentina. Little known about congenital transmission I. The specific aim this study to determine the rate compared non-I. We are conducting a prospective enroll at delivery, 10,000 women Argentina, 7,500 Honduras, 13,000 Mexico. measuring transmitted maternal antibodies by performing two rapid tests cord blood (Stat-Pak, Chembio,...
Background West Nile virus (WNV) infection is associated with acute morbidity and mortality in adults children. Information on the effects of maternal WNV illness during pregnancy early childhood development limited. This study was designed to examine relationship between birth developmental outcomes at age 3 years. Methods Mother‐child participants were identified using a national surveillance registry for women pregnancy. Maternal infant health data relevant family characteristics obtained...
Although rare, there have been isolated reports of autochthonous transmission Trypanosoma cruzi Chagas in the United States. In June 2006, a human case domestically transmitted T. was identified southern Louisiana. To examine localized risk infection area surrounding initial case, environmental surveys households and serological survey residents were performed between September 2008 November 2009. Human determined using rapid antigen field test, followed by confirmatory enzyme-linked...
Human infection with dengue virus (DENV) results in significant morbidity and mortality around the world. Current methods to investigate virus-associated changes insect feeding behaviors are largely restricted video analysis of events outside host or intravital microscopy. Electropenetrography, a method originally developed for plant-feeding insects, offers promising alternative by allowing high-resolution recording voltage across bite interface. We compared recordings from DENV-infected
We report the first record of Culex (Anoedioporpa) restrictor collected from a tree hole in Cauca Valley, Colombia, 2006.
