We conducted a literature review of available information on the species marine (Bacillariophyta) diatoms reported for coastal and ocean Colombian Caribbean Sea. present checklist 337 taxones 312 species, 19 varieties seven forms, grouped into 54 families 106 genera. The taxonomic classification was based system proposed by Round et al. (1990).

A check list of the marine species dinoflagellates reported from coastal and oceanic Colombian Caribbean Sea is presented. The based on revision bibliographical information available studies developed phytoplanktonic community. It reports a total 186 taxa corresponding to 169 with 27 varieties six forms. These are grouped in 32 genera, 17 families, orders, two classes. taxonomic classification was system proposed by Fensome et al. (1993).

The results of four independent complete drag-swab samplings a 31-farm broiler-production complex are described. Samplings vacant poultry farms (i.e., between flocks) and occupied containing chickens) were completed in 3-day intervals beginning July 1992 ending May 1993. During the first two sampling periods, assemblies dragged through each individual house pooled into one sample to evaluate overall incidence Salmonella detection among houses. second houses frequency on within house. Over...

The consistency and persistence of isolation specific serotypes Salmonella were evaluated on a 31-farm broiler complex following four complete sampling periods. A total 25 different isolated, with multiple frequently isolated simultaneously from individual farms. When the recovered farms further examined, common only seven occasions. Furthermore, five occasions consecutive samplings. casual association serotype isolations among similar flock placement dates was observed in one period. These...

Intermittent aortic regurgitation (AR) is an unusual complication after a mechanical prosthetic replacement. We describe rare case of intermittent dysfunction bileaflet valve in 41-year-old man with 21 mm Tri-technologies implanted 4 years before. Transthoracic echocardiography (TTE) before discharge was normal and prosthesis–patient mismatch ruled out. He admitted to our hospital because mild dyspnoea at effort. TTE revealed acute severe AR. The patient underwent surgery, during which...

Background: Tissue Doppler imaging (TDI) parameters of peak myocardial velocities (S′, E′, and A′) has been employed to assess the regional left ventricular function. The global function index (GFI) derived from TDI recently distinguish different etiologies hypertrophy. Objective: To analyze whether GFI or individual allows detecting degrees dysfunction in most frequent forms hypertrophic cardiomyopathy (HCM). Methods: = (E/E′)/S′ (where E is transmitral flow velocity, E′ early diastolic S′...

Thrombosis in a native aortic valve is rare complication which may lead to systemic embolization. A few cases of thrombosis previously abnormal valves have been described. In this report, we describe 42-year-old male who suffered two acute ischaemic attacks, one the upper right limb and another cerebral territory supplied by left sylvian artery, from thrombus that developed bicuspid stenotic valve. The diagnosis was made with transthoracic transoesophageal echocardiography, patient...

Colombia's favorable geographic location between the Caribbean Sea and Pacific Ocean combined with high shipping activity of its ports (nearly 30000 arrivals per year) make it susceptible to introduction non-native marine species. In light this potential threat, biological port surveys were conducted in three major areas Colombian (Cartagena, Santa Marta CoveA±as) as well adjacent reference (Bay Barbacoas, near BarAo, Ensenada de Gaira Rodadero CiA©naga CispatAi) March October 2010,...

Nitzschia martiana (Agardh) Van Heurck (Bacillariophyceae) se registra por primera vez viviendo en tubos sobre el sustrato rocoso para la región de Santa Marta costa Caribe colombiana. La colecta del material realizó zona intermareal y franja infralitoral. Se hicieron observaciones laboratorio con un microscopio fotónico. Su presencia local su distribución mundial muestran que especie ha presentado una amplia latitudinal entre los 52º N 32º S, posiblemente sufrido desplazamiento algunas...
