Bacteriocinogenic potential and virulence traits of Enterococcus faecium and E. faecalis isolated from human milk.

Conclusion: The presence of virulence genes in E. faecalis TA102 calls for careful monitoring of Enterococcus isolates for their safety parameters. PMID: 29238458 [PubMed]

Authors: Dangat K, Khaire A, Joshi S Abstract During the period of lactation, there is extensive growth and development of the mammary gland in order to fulfil the increased demands of milk for the growing infant. Angiogenesis plays a key role in alveolar development and facilitates optimal milk production. Vascular endothelial growth factor (VEGF) is one of the key growth factors regulating angiogenesis in mammary gland. Apart from VEGF, neurotrophins are also known to regulate angiogenesis through direct or indirect mechanisms. Few studies have demonstrated mRNA levels of neurotrophins and their receptors in mamm...

Authors: Grette K, Cassity S, Holliday N, Rimawi BH Abstract We performed a comprehensive systematic review of acute pyelonephritis in pregnancy using PubMed, SCOPUS,, and Ovid from inception to April 2018. About 7796 references were screened for inclusion, and 52 references from 1908 to 2017 were included. One hundred seven cases of acute pyelonephritis in pregnant women were reviewed. Gestational age at diagnosis was reported as 2 (2%), 43 (40%), and 51 (52%) during the first, second, and third trimesters, respectively. Maternal complications included sepsis (49%), acute respiratory distress sy...

This study aimed to investigate the level, duration, and dynamics of the human immune response against the SGL of Phlebotomus sergenti Parrot, 1917 (Diptera: Psychodidae), and to assess the immunoreactivity of human sera with SGL components in an endemic area of anthroponotic cutaneous leishmaniasis (ACL) in Iran. The study was carried out in 2-phase; longitudinal and cross-sectional. Sand flies were collected monthly from indoors and outdoors. In the longitudinal study, sera from healthy volunteers were collected monthly, and in the cross-sectional study, sera from healthy volunteers and patients with ACL lesion/s, w...

Discussion Until now, the main tool used for bacterial identification based on NGS of the 16S–23S rRNA encoding region was de novo assembly followed by BLASTN on NCBI database (Sabat et al., 2017), however, there was no evidence that it would be the most accurate and/or fastest method available. The de novo assembly and BLASTN is the only approach of the three that works at the contig level, and both the OTU clustering and mapping are performed at the read level. Using the NCBI database for these two last approaches would have resulted in odd results, since the NCBI database includes sequences that do not belong to ...

Abstract An enterocin-producing Enterococcus faecium T1 was isolated from Chinese Tibet cheese. The enterocin was purified by SP-Sepharose and reversed phase HPLC. It was identified as unique from other reported bacteriocins based on molecular weight (4629 Da) and amino acid compositions; therefore it was subsequently named enterocin T1. Enterocin T1 was stable at 80–100 °C and over a wide pH range, pH 3.0–10.0. Protease sensitivity was observed to trypsin, pepsin, papain, proteinase K, and pronase E. Importantly, enterocin T1 was observed to inhibit the growth of numerous Gram-negative ...
