ABSTRACT The conventional means of diagnosis histoplasmosis presents difficulties because the delay to time that is made, indicating need for implementation molecular assays. We evaluated 146 clinical samples from 135 patients suspected having using a previously reported nested PCR assay H istoplasma capsulatum -specific 100-kDa protein (the Hc100 PCR). In order determine specificity this test, we also used healthy individuals ( n = 20), respiratory disease with negative fungal cultures 29),...
Histoplasmosis causes a significant mortality, especially persons living with human immunodeficiency virus/acquired syndrome (HIV/AIDS) from developing countries where access to both appropriate diagnostic methods and antiretroviral therapy are limited. A total of 81 physicians assigned 17 Colombian departments (states) received training in the clinical, epidemiological, aspects histoplasmosis. Once this was during period October 2009–November 2012, these sent biological samples for...
We determined the value of culture and serological tests used to diagnose histoplasmosis. The medical records 391 histoplasmosis patients were analyzed. Diagnosis mycosis was assessed by culture, complement fixation, immunodiffusion tests; 310 (79.5%) male, 184 (47.1%) infected with human immunodeficiency virus (HIV). Positivity for cultures 35.7% (74/207), reactivity 95.2% (160/168), a combination both methodologies 16.9% (35/207) non-HIV patients. 75.0% (138/184), 92.4% (85/92), 26.0%...
En la literatura colombiana son escasos los reportes acerca de epidemiología tinea capitis. Realizar un estudio retrospectivo para describir el comportamiento esta micosis y sus agentes etiológicos, en una serie pacientes remitidos a centro diagnóstico especializado Medellín, Colombia. Estudio donde se analizaron registros entre años 1994 2013 micológico Unidad Micología Médica Experimental Corporación Investigaciones Biológicas (CIB), Fueron analizados 415 con sospecha clínica capitis, 133...
The aim of this study was to identify the most frequent yeasts in oral cavity adult individuals without immune disorders and associate presence these with different characteristics each individual. Oral rinse samples were obtained from 96 healthy adults cultured Sabouraud dextrose agar media CHROMagar. Yeasts identified by sequencing D1/D2 region 28S <i>rRNA</i> gene. Probable association among socio-demographic characteristics, body mass index, family personal medical history, hygiene,...
Pneumocystis jirovecii pneumonia is one of the diseases that most affects immunocompromised patients today, and under certain circumstances, it can be fatal. On other hand, more automatic tools based on artificial intelligence are required every day to help diagnose thus optimize resources healthcare system. It therefore important develop techniques mechanisms enable early diagnosis. One widely used in diagnostic laboratories for detection its etiological agent, jirovecii, optical...
Background: The yeasts species determination is fundamental not only for an accurate diagnosis but also establishing a suitable patient treatment. We performed concordance study of five methodologies the identification oral isolates Candida in Colombia. Methods: Sixty-seven were tested by; API® 20C-AUX, Vitek®2 Compact, Vitek®MS, Microflex® and molecular test (panfungal PCR sequencing). commercial cost processing time samples was done by graphical analysis. Results: Panfungal differentiated...
El objetivo de este trabajo fue aislar Staphylococcus aureus quesos comercializados en el mercado central la ciudad Bagua, estudio tipo descriptivo y no experimental realizado “Laboratorio ciencias Naturales” Universidad Nacional Intercultural Fabiola Salazar Leguía Bagua; se recolectaron 40 muestras quesos, necesitándose 100 g. que fueron sembrados Agar Manitol Salado confirmó con prueba coagulasa. Se evaluaron diferentes tipos como: queso molido, fundido, parmesano, suizo cortes. terminó...
La histoplasmosis y la paracoccidioidomicosis son enfermedades micóticas sistémicas endémicas frecuentes en Colombia. se considera una micosis oportunista individuos con alteraciones los mecanismos de defensa específicos mediados por células, particularmente aquellos pacientes infectados el virus inmunodeficiencia humana. Por contrario, número asociada al sida es relativamente bajo. Hasta ahora, prevalente población no inmunocomprometida. Actualmente existen informes literatura sobre casos...
Abstract Background. Cryptococcosis is a potentially life-threatening fungal disease caused by encapsulated yeasts of the genus Cryptococcus , mostly C. neoformans or gattii. Cryptococcal meningitis most frequent clinical manifestation in humans. Neutralizing autoantibodies (auto-Abs) against granulocyte-macrophage colony-stimulating factor (GM-CSF) have recently been discovered otherwise healthy adult patients with cryptococcal meningitis, gattii . We hypothesized that three Colombian two...
La conidiobolomicosis es una micosis subcutánea causada por un hongo saprofito, Conidiobulus spp. perteneciente a la clase Zigomicetos, orden Entomoftorales, que habita en regiones tropicales. manifestación clÃnica clásica deformidad progresiva de estructuras faciales y su diagnóstico se basa cultivos zona afectada el estudio histopatológico, siendo âfenómeno Splendore-Hoeppliâ hallazgo más caracterÃstico. Dada baja frecuencia presentación, no existe consenso sobre mejor...
Disseminated fusariosis is an opportunistic infection caused by the hyaline fungus Fusarium spp. and occurs mainly in patients with leukemia.Two cases of disseminated pediatric are presented. Profound prolonged neutropenia, fever, myalgia, skin lesions legs were present two girls leukemia undergoing chemotherapy. In first case, was confirmed anatomopathological findings, pathogen isolation, polymerase chain reaction. second solani mass spectrometry using blood cultures lesion samples.It...
Pneumocystis jirovecii Pneumonia is one of the diseases that most affect immunocompromised patients today, and under certain circumstances, it can be fatal. One widely used techniques in diagnostic laboratories for detection its etiological agent optical microscopy. However, some disadvantages this technique are low sensitivity, accuracy, high dependence on an expert to make diagnosis. Then, work aims develop a computational tool based deep learning approach automatically detect presence P....
