The prevalence of virulence determinants in methicillin-resistant Staphylococcus aureus isolated from different infections in hospitalized patients in Poland. | LitMetric
Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for hard-to-treat infections. The presence of 19 virulence genes in 120 MRSA isolates obtained from hospitalized patients and genetic relationships of these isolates were investigated. The eno (100%) and ebps (93.3%) genes encoding laminin- and elastin binding proteins, respectively, were ubiquitous. Other adhesion genes: fib (77.5%), fnbB (41.6%), bbp (40.8%), cna (30.8%) encoding proteins binding fibrinogen, fibronectin, bone sialoprotein and collagen, respectively, and map/eap (62.5%), encoding Eap, were also frequent. The etB and etD genes, encoding exfoliative toxins, were present in 15.6% and 12.5% isolates, respectively. The splA, splE and sspA, encoding serine protease were detected in 100%, 70.8% and 94.2% isolates, respectively. The tst gene, encoding toxic shock syndrome toxin-1 was found in 75% isolates. The cna, map/eap and tst genes were the most common in wound isolates and much less common in blood isolates. We identified 45 different spa types, t003 (21.7%) and t008 (18.8%) being the most common. The t003 was the most frequent among isolates from the respiratory tract (35.5%), while t008 in blood isolates (40%). Identification of virulence factors of MRSA is important for evaluation of pathogen transmission rate and disease development.
Measles or rubeola is caused by an enveloped single-stranded RNA virus belonging to the genus Morbillivirus in the Paramyxoviridae family. Here, we present five adult measles patients. The laboratory confirmation of measles by serology/polymerase chain reaction (PCR) was carried out in the National Measles Laboratory as per WHO standard operating procedure at the Department of Virology, Post Graduate Institute of Medical Education and Research, Chandigarh, India.
Objectives: To describe changes in respiratory syncytial virus (RSV) epidemiology, its associated clinical outcomes and predictors of severe acute lower respiratory tract infection (ALRTI) pre- and post-COVID-19.
Methods: In this retrospective cohort, we analysed data from electronic medical record of children <5 years who were hospitalized at Jordan University Hospital with RSV-associated ALRTI from 2018 to 2022.
Results: 325 inpatients with respiratory infections were included.
The directional and sequential flow of cytokinin in plants is organized by a complex network of transporters. Genes involved in several aspects of cytokinin transport have been characterized; however, much of the elaborate system remains elusive. In this study, we used a transient expression system in tobacco (Nicotiana benthamiana) leaves to screen Arabidopsis (Arabidopsis thaliana) transporter genes and isolated ATP-BINDING CASSETTE TRANSPORTER C4 (ABCC4).
This study explored the impact of sodium acetate (Na-acetate) impact on lipid, carotenoid, and β-carotene production by the newly isolated strain . Batch and fed-batch bioreactor cultures were employed to optimize growth conditions and product yields. fed with Na-acetate in the yeast medium was evaluated in the batch bioreactor culture.
Background: Amino acid (AA) substitutions in the fusion protein of respiratory syncytial virus (RSV) and their effects remain unclear. We aimed to analyze AA substitutions in main neutralizing epitopes of the fusion (F) protein.
Methods: We analyzed F protein genes of 236 RSV strains isolated from children hospitalized with RSV infection in Fukushima, Japan (June 2008-February 2023).
