The grape microflora is complex and includes filamentous fungi, yeasts and bacteria with different physiological characteristics and effects on wine production. Most studies have focused on the wine microbiota, but a few studies have reported the ecology of grape microorganisms. Some of these organisms - such as non Botrytis bunch rotting fungi, which greatly influence the safety or sensory quality of wine, due to the production of mycotoxins and off-flavors, respectively - are considered to be spoilage agents. We review here the diversity of filamentous fungi on grapes and the factors influencing their development, such as grape ripening stage, environmental factors (climate, rain and cultivation practices), grape variety and grape health status. We also discuss the pathways by which mycotoxins and off-flavors are produced, the control of the population, the metabolites responsible for wine spoilage and the methods for detecting and characterizing the microorganisms involved. © 2013 Elsevier Ltd.

For expressing the quality of fruits, in terms of food and therapy, the content of the main indicators of pepper fruit quality was monitored (Capsicum annum L), which are: vitamin C, carotene and protein, depending on the local population. Several local populations of Oltenia have been studied and a series of plants' morphological features were pursued, and chemical determinations were made in fruits at physiological maturity. The methods of analysis were titrimetric for vitamin C; refract metric for carotene and the Kendal method for protein. The content values in vitamin C, carotene and protein were related to the average experience, which is considered as a percentage of 100 %. The purpose of the experiments was to determine the local population of Capsicum annum, with the best indicators taken in the study and its local implementation by taking into account the benefit that its consumption has on the human body, as well as obtaining different therapeutic preparations.

Canine dirofilariasis or heartworm disease caused by Dirofilaria immitis is a serious animal life threatening disease. Adult worms live in the lung arteries and right heart, causing cardiovascular and pulmonary parenchyma changes. The aim of this study was the radiographic evaluation of the dogs' thorax naturally infected with D. immitis in southern Romania. Medical records of 83 dogs (45 males and 38 females), diagnosed positive for D. immitis with thorax radiographs have been reviewed. Fiftysix (67.47%) were pure breeds and 27 (32.53%) mongrels, aged between 2 and 16 years (7.51 years average). Sixty-two dogs (74.70%) presented cardiopulmonary radiographic changes and 21 dogs (25.30%) were without radiographic signs. Sixty dogs (72.29%) had vascular radiographic changes, 51 dogs (61.44%) had pulmonary parenchymal changes, 39 dogs (46.99%) had changes in heart shape and silhouette, and 2 dogs (2.41%) had pleural effusions. On lateral radiographs, the average VHS rate on the evaluated dogs was higher than the reference. The obtained results suggest that thoracic radiography represents a useful tool in assessing the presence and severity of cardiopulmonary changes in dogs infected with D. immitis. © 2014 University of Bucharest.
