BACKGROUND: Mexico is one of the most important contributors of drug and multidrug-resistant tuberculosis in Latin America; however, knowledge of the genetic diversity of drug-resistant tuberculosis isolates is limited. METHODS: In this study, the genetic structure of 112 Mycobacterium tuberculosis strains from the southeastern Mexico was determined by spoligotyping and 24-loci MIRU-VNTRs. FINDINGS: The results show eight major lineages, the most of which was T1 (24%), followed by LAM (16%) and H (15%)...

The population that lives in areas where organochlorine pesticides were spread in the past is still exposed to them through contaminated food, particulate matter, and vapors. Due to their lipophilic properties and resistance to metabolic reactions, they accumulate in tissues and fluids rich in lipids. The aim of the study was to monitor the concentrations of organochlorine pesticides in forensic adipose tissue samples of adult inhabitants of Veracruz City, Mexico, and compare their time trend levels from 1988 to 2014...

This study focused on dating of a sediment core from the Alvarado Lagoon System, Veracruz, Mexico, calculating the sedimentation rate by using210 Pb to determine the tendency towards pollution by polycyclic aromatic hydrocarbons, organochlorides, the metals Cd, Cr, Cu, Hg, Ni, Pb, and V, and organic matter content. The activity of total Pb and supported Pb in the samples was 83.1 and 29.5 Bq kg-1 , respectively, whereas the average estimated sedimentation rate was 0.48 ± 0.09 cm per year-1 . The organic matter values exhibited linear behavior throughout the historical profile, with values under 2...

Endemic populations of Hechtia perotensis have been described in Puebla and Veracruz, Mexico. Good quality seed collections can be used in conservation, research and ecological restoration. To evaluate seed quality of wild and endemic species, some compounds are used as effective promoters of germination, such as potassium nitrate (KNO3) and gibberellic acid (AG3), because they increase seed germination capacity and reduce latency. The triphenyl tetrazolium chloride (tetrazolium) test correlates seed viability because it is based on the activity of dehydrogenases in live tissues that catalyze mitochondrial respiration...

In Mexico there are 29 species of Amnestus, of which six species are from Veracruz. The morphological features and illustrations of immature stages of A. rugosus are presented. Notes about the biology and behavior were included. The nymphal and adult stages of A. rugosus were found in remnants of riparian vegetation of the mesophilous forest in La Antigua river basin, Veracruz, Mexico. Twelve sites in five localities were selected and the specimens were sampled in rainy (July) and dry (April) seasons of 2012...

Payment for hydrological services (PHS) are popular tools for conserving ecosystems and their water-related services. However, improving the spatial targeting and impacts of PHS, as well as their ability to foster synergies with other ecosystem services (ES), remain challenging. We aimed at using spatial analyses to evaluate the targeting performance of México's National PHS program in central Veracruz. We quantified the effectiveness of areas targeted for PHS in actually covering areas of high HS provision and social priority during 2003-2013...

We aimed to determine the seroprevalence of infection with Neospora caninum, Leptospira , and bovine herpesvirus type 1 and risk factors associated with these infections in water buffaloes in Veracruz State, Mexico. Through a cross-sectional study, 144 water buffaloes (Bubalus bubalis) raised in 5 ranches of Veracruz were examined for anti-N. caninum and anti-bovine herpesvirus type 1 antibodies by enzyme immunoassays, and anti-Leptospira interrogans antibodies by microscopic agglutination test. Of the 144 buffaloes studied, 35 (24...

BACKGROUND AND AIM: Dengue Fever (DF) is a human vector-borne disease and a major public health problem worldwide. In Mexico, DF and Dengue Hemorrhagic Fever (DHF) cases have increased in recent years. The aim of this study was to identify variations in the spatial distribution of DF and DHF cases over time using space-time statistical analysis and geographic information systems. METHODS: Official data of DF and DHF cases were obtained in 32 states from 1995-2015...

Early insulinization therapy is regarded as an efficient aid to improve long term control and quality of life in patients with diabetes mellitus type 2 (DM2). Nevertheless, both patients and medical staff confront barriers in using this therapeutic tool. This study employs a qualitative approach to explore the barriers to early insulinization among medical staff from the public sector in the city of Xalapa, Veracruz, México. Between 2015 and 2016, in-depth interviews were conducted with general and specialist physicians offering primary health care to patients with DM2...

OBJECTIVES: To investigate if, in Mexican adolescents, body weight and caries severity are associated, and if this association differs between rural and urban populations. METHODS: Adolescents from the rural area of Tepancan and the city of Veracruz were enrolled. Caries was recorded using the International Caries Detection and Assessment System and the body mass index (BMI) was calculated. Oral habits (toothbrushing, flossing, dental check-ups) and dietary patterns (sweets intake) were assessed...

The genus Leptospira encompass 22 species of spirochaetes, with ten pathogenic species that have been recorded in more than 160 mammals worldwide. In the last two decades, the numbers of records of these agents associated with bats have increased exponentially, particularly in America. Although order Chiroptera represents the second most diverse order of mammals in Mexico, and leptospirosis represents a human and veterinary problem in the country, few studies have been conducted to identify potential wildlife reservoirs...

The genus Rhinoptera is composed of eight species widely distributed in tropical, subtropical and temperate coastal waters, which inhabit bays, estuaries and river mouths. Cownose ray Rhinoptera bonasus has been reported to inhabit the Western Atlantic including the Gulf of Mexico and the Caribbean, whereas the Brazilian cownose ray R. brasiliensis has been considered endemic to the coast of Brazil. Recent reports of R. brasiliensis in the Gulf of Mexico bring about the question of whether the species has a wider range than previously reported...

Micropygomyia (Coquillettimyia) nahua sp. nov., is described and illustrated based on male and female characteristics. Specimens were collected in the Municipality of Naolinco, state of Veracruz, Mexico. This new species of phlebotomine sand fly has characteristics corresponding to the series vexator Fairchild of Galati, with male similar to Micropygomyia (Coquillettimyia) apache (Young & Perkins), Mi. (Coq.) oppidana (Dampf) and Mi. (Coq.) vexator (Coquillett), but recognized by the male paramere structure and simple apex of aedeagal ducts in the male, the later exception for this species series...

In this study, we systematized available distribution data, obtained from biological databases and relevant literature, for Mexican species belonging to the tribe Phanaeini. The main objectives were to provide an overall description of the distribution records in biological collections, to detect potential sampling biases, to describe the seasonality of collections and to obtain species distribution models using the Desktop GARP algorithm. A total of 5,562 records, corresponding to 32 species in Mexico, were compiled, including the recently described Phanaeus zoque Moctezuma & Halffter, 2017...

In Mexico, the first outbreaks suggestive of the circulation of the porcine epidemic diarrhea virus (PEDV) were identified at the beginning of July 2013. To identify the molecular characteristics of the PEDV Spike (S) gene in Mexico, 116 samples of the intestine and diarrhea of piglets with clinical signs of porcine epidemic diarrhea (PED) were obtained. Samples were collected from 14 farms located in six states of Mexico (Jalisco, Puebla, Sonora, Veracruz, Guanajuato, and Michoacán) from 2013 to 2016. To identify PEDV, we used real-time RT-PCR to discriminate between non-INDEL and INDEL strains...
