The vicuña (Vicugna vicugna; Miller, 1924) is a conservation success story, having recovered from near extinction in the 1960s to current population levels estimated at 275 000. However, lack of information about its demographic history and genetic diversity has limited both our understanding of its recovery and the development of science-based conservation(More)
Disinfection for drinking water reduces the risk of pathogenic infection but may pose chemical threat to human health due to disinfection residues and their by-products (DBPs) when the organic and inorganic precursors are present in water. More than 250 DBPs have been identified, but the behavioral profile of only about 20 DBPs are adequately known. In the(More)
An indirect enzyme-linked immunoabsorbent assay (ELISA) for Trypanosoma cruzi was developed using epimastigote secretion/excretion proteins (ESEA antigens) obtained from axenic culture supernatants. A panel of 120 serum samples from subjects with confirmed Chagas disease (n = 50), healthy controls (n = 50), and patients with other parasitic diseases (n =(More)
The current study aimed to determine the seroprevalence of Trypanosoma cruzi infection in Sucre State, Venezuela, and its association with epidemiological risk factors. The cluster sampling design allowed selecting 96 villages and 576 dwellings in the State's 15 municipalities. A total of 2,212 serum samples were analyzed by ELISA, HAI, and IFI.(More)
Papaya bunchy top (PBT) disease has been associated with Rickettsia-related proteobacterium. To study the occurrence of this proteobacterium in Cuba, during 2012, we collected 264 samples from asymptomatic and symptomatic papaya trees in three regions of Cuba. Symptomatic tissue evaluated by transmission electron microscopy revealed Rickettsia-like(More)
INTRODUCTION Trypanosoma cruzi infection in humans has been extensively studied in Venezuela; however, in reservoirs it has been less investigated. OBJECTIVE The objective of this study was to determine the seroepidemiology of T. cruzi in the state of Sucre, Venezuela. MATERIALS AND METHODS A cross-sectional and prospective study conducted in 95 towns(More)
Results of 14 mandibular reconstruction by a composite muscular flap of the pectoralis major and trapezium muscles during widespread glossopelvimandibular excisions are described. The technique employed is outlined, emphasis being placed on the need to observe strict precautions during removal and application of the bone component, to avoid accidental(More)
Reconstruction of the pinna of the ear is a difficult enterprise and overall results are poor. It is nevertheless essential to persist since despite the hazards of such surgery many patients wish to have an operation since they are unable to tolerate their deformity. Apart from the cutaneous problem, the most important point remains that of bitterness.(More)
