The versatility of the yeast experimental model has aided in innumerable ways in the understanding of fundamental cellular functions and has also contributed towards the elucidation of molecular mechanisms underlying several pathological conditions in hum... see more

Toxoplasmosis is important zoonotic disease. This disease infected multiple species of birds, mammals, reptile and amphibian. Moreover, multiple complications have been reported in human and livestock which is important in term of their health and adverse... see more

Cross-species amplification of microsatellites is a common procedure to obtain suitable markers to be used in population genetic studies. Primers designed for one (source) species are used to amplify homologous loci in related (target) species. It is expe... see more

Reithrodontomys sumichrasti is distributed from central México to Panama.  Previous studies using DNA sequences suggest the existence of distinct clades that may deserve species-level recognition.  Here, we use multiple methods of species delimi... see more

Trypanosomes cause anaemia and are responsible for widespread morbidity and mortality particularly in imported breeds of animals found in sub-tropical and tropical parts of the world. Light microscopy and polymerase chain reaction (PCR) were used to detec... see more

This study examined twenty six microsatellite primers developed from three cyprinid fishes (Cyprinus carpio, Barbus barbus and Barbonymus gonionotus) in two indigenous mahseer, Tor douronensis and T. tambroides. A total of 10 (38%) and 12 (46%) primers we... see more

Infecciones oportunistas de origen bacteriano más frecuentes en pacientes infectados con el virus de la inmunodeficiencia humana (VIH) Most frequent opportunistic infections from bacterial origin in patients infected by Human Immunodeficiency Virus (HIV)Infecciones oportunistas de origen bacteriano más frecuentes en pacientes infectados con el virus de la inmunodeficiencia humana (VIH) Most frequent opportunistic infections from bacterial origin in patients infected by Human Immunodeficiency Virus (HIV)Se realizó un estudio descriptivo, retrospectivo y transversal, con el objetivo de conocer los aislamientos bacterianos más frecuentes encontrados en diferentes muestras biológicas (esputo, sangre y orina) de pacientes con diagnóstico de VIH/SIDA, que asistieron a la consulta externa en el Hospital Abel Santamaría Cuadrado, en el período comprendido entre enero a diciembre de 2007. Se encontró que el mayor número de aislamientos fue a partir de muestras de esputos y Pseudomonas aeruginosa, resultando el microorganismo más aislado de todas las muestras (28,5 %). En la sangre la bacteria aislada con mayor frecuencia fue Staphylococcus epidermidis (48,5 %). En la orina, el microorganismo uropatógeno más frecuente encontrado fue Escherichia coli (43,5 %). Existió una especificidad de especie según localización anatómica en los pacientes VIH/SIDA. Palabras clave: staphylococcus epidermidis/ aislamiento & purificación, pseudomonas aeruginosa/ aislamiento & purificación, infecciones por escherichia coli/ diagnóstico, síndrome de inmunodeficiencia adquirida /complicaciones. ABSTRACT A descriptive, retrospective and cross-sectional study was conducted aimed at knowing the most frequent bacterial isolations found in different biological samples (sputum, blood and urine) of HIV/AIDS patients attending to the outpatient office at "Abel Santamaria Cuadrado" University Hospital, from January to December 2007. Most of the numbers of isolations were from sputum samples, resulting Pseudomonas aeruginosa the most isolated microorganism in all samples (28, 5%). In blood the isolated bacteria having the greatest frequency was Staphylococcus epidermidis (48, 5%). In urine, the uropathogenic microorganism most frequent found was Escherichia coli (43, 5%). Specificity of the species existed according to anatomic localization in HIV/AIDS patients. Key words: staphylococcus epidermidis/isolation & purification, pseudomonas aeruginosa/ isolation & purification, escherichia coli infections/diagnosis, Acquired Immunodeficiency Syndrome/complications.
