Aedes aegypti oviposition in urban communities in the Northern Chihuahuan Desert.

Background Objectives: Aedes aegypti (Linnaeus) is the vector of multiple arboviruses, the most important being dengue viruses (DENV) that causes more than 90 million cases per year. The expanded range of Ae. aegypti into temperate climates has contributed to the increasing risk of DENV to new human populations.

Genomic Analysis of in the Northern Chihuahuan Desert of Texas and Mexico.

Aedes aegypti, is the primary vector of dengue, Chikungunya, Zika, and yellow fever viruses. Both natural and human-impacted landscapes have selective pressures on Ae. aegypti, resulting in strong genomic structure even within close geographical distances.

Clinical and pathological factors associated with Ehrlichia canis in companion dogs.

Introduction: Canine monocytic ehrlichiosis (CME) is a disease caused by the Gram-negative bacteria Ehrlichia canis, a bacterium that affects domestic dogs but can also infect humans. The diagnosis implies a challenge due to its diversity in clinical manifestations.

Methodology: The frequency of E.

Characterization of a Dengue Virus Serotype 1 Isolated from a Patient in Ciudad Juarez, Mexico.

Dengue (DEN) is the most important human arboviral disease worldwide. Sporadic outbreaks of DEN have been reported since 1980 in urban communities located along the border in southeast Texas and northern Mexico. Other than the Rio Grande Valley region of TX, autochthonous transmission of DENV has not been reported from any other US border communities.

Serologic evidence of rickettsial diseases associated with tick bites in workers of urban veterinary clinics.

Background & Objectives: Rickettsial and other zoonotic diseases are a latent risk for workers of veterinary clinics. The objective of this study was to evaluate the prevalence and the associated risk factors of parasitosis caused by Rhipicephalus sanguineus, and to estimate the seroprevalence of rickettsial diseases in workers of urban veterinary clinics of Juárez city, México.

Methods: The participants of the study were recruited from 63 private veterinary clinics and hospitals.

Occupational risk for personnel working in veterinary clinics through exposure to vectors of rickettsial pathogens.

Workers at veterinary clinics are exposed to zoonotic pathogens, which, though infrequently, can lead to serious consequences. The aim of the present study was to estimate the seroprevalence for rickettsial pathogens in veterinary clinic personnel in Ciudad Juárez, Chihuahua, Mexico. Voluntary participants included 106 veterinarians, 19 pet groomers, 36 veterinary assistants and 6 administrative workers who supplied blood samples taken by venipuncture.

Serological Evidence of Dengue and West Nile Virus Human Infection in Juarez City, Mexico.

Arboviruses are significant causes of human and animal diseases, globally. In the Rio Grande Valley of the United States-Mexico border region, endemic transmission of Dengue (DENV), Zika (ZIKV), and West Nile (WNV) viruses have been documented as a cause of human disease. Otherwise, very little is known about the distribution of arboviruses and their possible cause of human disease in other areas of the United States-Mexico border region.

DNA Methylation of Cellular Retinoic Acid-Binding Proteins in Cervical Cancer.

This study determined the methylation status of cellular retinoic acid-binding protein () gene promoters and associated them with demographic characteristics, habits, and the presence of human papilloma virus (HPV) in patients with cervical cancer (CC), low and high squamous intraepithelial lesions, and no intraepithelial lesion. Women (n = 158) were selected from the Colposcopy Clinic of Sanitary Jurisdiction II in Ciudad Juarez, Chihuahua, Mexico. Demographic characteristics and habit information were collected.

Introducción: las lesiones intraepiteliales escamosas (LIE) son un estado de transición hacia el cáncer cervicouterino (CaCu) y un déficit de micronutrientes puede acelerar este proceso. Por ello, determinar la existencia de este déficit y conocer qué factores se asocian permitiría una posible prevención en esta población de riesgo.Objetivo: determinar la presencia de alguna deficiencia de micronutrientes involucrados en el proceso anticancerígeno y asociar este déficit con hábitos y factores demográficos en pacientes con LIE de Ciudad Juárez, Chihuahua, México.

[Geospatial distribution and detection of dengue virus in Aedes (Stegomyia) aegypti mosquitos in Ciudad Juárez, Chihuahua, Mexico].

Objective: To determine the distribution of Aedes aegypti in Ciudad Juárez, Mexico and evaluate it as a carrier of the dengue virus.

Material And Methods: Mosquitoes were collected using CDC minitraps. Nearest neighbor and K-function were used as geospatial tools.
