Among Chagas disease triatomine vectors, the largest genus, Triatoma, includes species of high public health interest. Triatoma dimidiata, main vector throughout Central America and up to Ecuador, presents extensive phenotypic, genotypic, behavioral diversity in sylvatic, peridomestic domestic habitats, non-domiciliated populations acting as reinfestation sources. DNA sequence analyses, phylogenetic reconstruction methods, genetic variation approaches are combined investigate haplotype...
Triatoma dimidiata is among the main vectors of Chagas disease in Latin America. However, and despite important advances, there no consensus about taxonomic status phenotypically divergent T. populations, which most recent papers are regarded as subspecies.
The primary mode of transmission for Chagas disease is vector-borne transmission, spread by hematophagous insects the Triatominae subfamily. In Mexico, triatomine Meccus pallidipennis particularly significant in Trypanosoma cruzi. This study focused on analyzing protein expression and modifications glycosylation different regions digestive tract fifth-instar nymphs M. pallidipennis. Two gut sections were dissected extracted: anterior midgut (AMG) proctodeum or rectum (RE). Proteins extracted...
Summary The wide geographical distribution of Triatoma dimidiata , one the three major vectors Chagas disease, ranges from Mexico to northern Peru. Since this species occupies a great diversity artificial and natural ecotopes, its eradication is extremely difficult. In order assist control efforts, we used chromosome analyses DNA amount as taxonomic markers study genetic variability in populations T. Mexico, Guatemala, El Salvador Colombia. We differentiated groups or cytotypes defined by...
Chagas disease is a vector-borne life-threatening illness originally confined to the Americas. Seroprevalence studies have been reported in Mexican state of Chiapas; nevertheless, no clinical/cardiological conducted detect underage cases. The aim present work was cases Chiapas.A serological screening by ELISA on 1556 blood samples from school pupils; seropositiv- ity confirmed indirect and immunofluorescence. Seropositive were clinically assessed hospital, electrocardiographic...
Eight Triatoma dimidiata populations from different geographic regions were compared along with related species using traditional morphometry of head characters. A method for removing allometric change was used the intraspecific comparisons, and scaling isometric size interspecific comparisons. The comparison showed significant shape differences between T. correlating geography, showing a separation northern, intermediate, southern collections (more evident in females), supporting idea that...
One of the most daunting challenges for Chagas disease surveillance and control in Mexico is lack community level data on vector distributions.Although many states now have assembled representative domestic triatomine collections, only two specimens had been collected reported previously from state Guanajuato.Field personnel stateÕs Secretarõ ´a de Salud conducted health promotion activities 43 46 counties received donations a total 2,522 between 1998 2002.All were identiÞed, live insects...
Vectors of Trypanosoma cruzi, parasite responsible for Chagas disease, are divided in intradomestic, peridomestic and sylvatic. The intradomestic Triatoma barberi dimidiata, two species that represent the highest health risk among Mexican population. dimidiata is a found mainly inside human habitats, but Yucatan, it corresponds to peridomicile vectors. Also most disease vectors found: Meccus bassolsae, M. longipennis, mazzottii, M pallidipennis, phyllosomus, picturata, gerstaeckeri, T...
Infected diabetic foot is the most common reason for hospitalization and complications in patients with type 2 diabetes mellitus (DM2). Methicillin-resistant Staphylococcus aureus (MRSA) frequently isolated from such lesions, its presence growing, seriously deteriorating infected patient’s quality of life. The aim this study was to assess prevalence MRSA as well other microbiota 100 diagnosed (DM2) ulcers at Hospital General de Mexico. main results obtained show a (42%), followed by...
Chagas disease is a parasitic infection mainly found in Latin America; it transmitted by triatomine, also known as assassin bug or kissing bug. In humans, the parasite causes mostly cardiac disorders. Two-thirds of Mexican territory are regarded risk areas for vector transmission Trypanosoma cruzi, causal agent. The can be blood-borne trypomastigote an intracellular amastigote. progression and severity lesions could due to frequent reinfections highly virulent strains. A total 3,327...
Background: The objective of this study was to determine the clinical and surgical characteristics diabetic foot ulcers in a tertiary level hospital Mexico.Methods: We performed longitudinal, descriptive from July, 2012 August, 2015 on sample composed 100 patients with type 2 diabetes mellitus infected ulcers. analyzed socio-demographic variables, comorbidities, ulcers, applied treatment.Results: found that most affected areas were forefoot (48%) plantar region (55%) foot. Also, arrived...
La enfermedad de Chagas, causada por el Trypanosoma cruzi, está considerada como la parasitosis más grave en América.Se transmite principalmente triatominos (chinches).El doctor Mazzoti reportó los dos primeros casos humanos México.La forma transmisión es entrada al organismo parásitos heces del insecto, transfusión sanguínea, madre a hijo, trasplante órganos y accidentes laboratorio.En México se estima que 1.1 millones personas están infectadas; incidencia 2012 fue 0.70 100 000...
Little is known about how human disease vectors will modify their life history patterns and survival capacity as a result of climate change. One case that Chagas disease, which has triatomine bugs Trypanosoma cruzi parasite, respectively. This work aimed to determine: (i) the activity prophenoloxidase system (prophenoloxidase phenoloxidase activity, two indicators immune ability) in three intestine regions (anterior midgut, posterior midgutand rectum) bug Meccus pallidipennis under...
Triatoma dimidiata (Latreille 1811) Reduviidae Triatominae is the main vector of Chagas disease in several countries Latin America. As for other species, characterization T. subpopulations within particular geographical regions or occupying different habitats could help better planning control actions. A first objective this study was to evaluate antennal phenotype as a phenetic marker characterize populations collected geographic areas and domestic sylvatic habitats. second relationships...
Because information about genome size in triatomines is scarce and contradictory, we performed DNA quantification by flow cytometry 13 species belonging to five genera (Dipetalogaster, Eratyrus, Panstrongylus, Rhodnius, Triatoma) infer overall tendencies phylogenetic associations. The results show that the haploid content of subfamily Triatominae varies nearly 4-fold, from<0.7 pg Rhodnius (0.6x10(9) bp) 2.7 Triatoma delpontei (2.6x10(9) bp). Considering present similar chromosome numbers,...
Chagas disease is a key health problem in Latin America and caused transmitted by Trypanosoma cruzi triatomine bugs, respectively. Control of triatomines has largely relied on the use pyrethroids, which proved to be ineffective long term. Alternatively, entomopathogenic fungi been implemented control bugs. These are highly efficient as they induce reduction immune response insects. Meccus pallidipennis main vector Mexico. In this work we investigated effects two fungi, Metarhizium anisopliae...
