Epidemiology and genetic variability of respiratory syncytial virus in Portugal...
Sáez-López, Emma; Cristóvão, Paula; Costa, Inês; Pechirra, Pedro; Conde, Patrícia; Guiomar, Raquel; Peres, Maria João; Viseu, Regina; Lopes, PauloRespiratory syncytial virus (RSV) is associated with substantial morbidity and mortality since it is a predominant viral agent causing respiratory tract infections in infants, young children and the elderly. Considering the availability of the RSV vaccines in the coming years, molecular understanding in RSV is necessary.

Sáez-López, Emma; Cristóvão, Paula; Costa, Inês; Pechirra, Pedro; Conde, Patrícia; Guiomar, Raquel; Peres, Maria João; Viseu, Regina; Lopes, PauloIntroduction: Respiratory syncytial virus (RSV) is associated with substantial morbidity and mortality since it is a predominant viral agent causing respiratory tract infections in infants, young children and the elderly. Considering the availability of the RSV vaccines in the coming years, molecular understanding in RSV is necessary. Objective: The objective of the present study was to describe RSV epidemiolog...
Severe RSV infections in children and elderly during 2017/2018 winter season
Guiomar, Raquel; Pechirra, Pedro; Costa, Inês; Cristóvão, Paula; Conde, Patrícia; Nunes, Baltazar; Rodrigues, Ana Paula; Côrte-Real, RitaBackground: Respiratory syncytial virus (RSV) is one of the most frequent and important respiratory viral agent that causes respiratory infection complications in younger children and elderly. RSV has an autumn / winter seasonality detected in cocirculation with influenza and other respiratory viruses. Material and Methods: During 2017/2018 season, 14 hospitals from Portugal mainland and Atlantic Island tested ...
Influenza virus type/subtype and different infection profiles by age group duri...
Guiomar, Raquel; Pechirra, Pedro; Cristóvão, Paula; Costa, Inês; Conde, Patrícia; Côrte-Real, Rita; Branquinho, Paula; Garcia, David; Conde, SílviaBackground: Influenza has a major impact in hospitalization during each influenza season. We analysed the influenza type/subtype distribution by age group and medical care wards (ambulatory, hospital, intensive care unit). Material and Methods: During 2017/2018 season, 14 hospitals from Portugal mainland and Atlantic Island (Azores and Madeira) reported to the National Influenza Centre 13747 cases of respirator...
Survival of Lactobacillus sakei during heating, drying and storage in the dried...
Ferreira, Vânia; Soares, Vânia; Santos, Cristina; Silva, Joana; Gibbs, Paul A.; Teixeira, PaulaSpray-dried cells of Lactobacillus sakei CTC 494 survived ca. 60% longer in the spray dried state when cells were grown in the presence of 20 g sucrose l)1 or 12.5 g monosodium glutamate l)1. No significant differences were observed in viability during storage in the freeze dried state with the addition of these compounds to the growth medium, nor in survival during a heat treatment (55ºC). Both sucrose and glu...
Effect of various protecting compounds added to the growth medium upon survival...
Ferreira, Vânia; Soares, Vânia; Santos, Cristina; Silva, Joana; Gibbs, Paul A.; Teixeira, PaulaThe aim of the present study was to investigate if the presence of sorbitol, myoinositol, xylose, mannose and Tween 80 in the growth medium increased the survival of L. sakei during heating, freezing, freeze drying and storage of freeze dried cells. Survival during freezing was enhanced by ca. 8% when glycerol was present in the growth medium. Viability during freeze-drying and storage in the dried state was im...
