Aislamiento, identificación y actividad antimicrobiana de bacterias del ácido láctico del estuario de Bahía Blanca

This study analyzed the biodiversity of lactic acid bacteria present in the Bahía Blanca Estuary and their antimicrobial activity against pathogens associated with the cultivation of salmonid. A total of 21 lactic acid bacteria (LAB) strains were isolated from superficial sediments and fish of the estuary. The fish species were selected from those that spend most of their life cycle in the estuary. According to 16S rDNA analysis, isolates were affiliated with the genera Lactobacillus, Pediococcus, Leuconostoc, Enterococcus and Weissella. The predominant LAB isolates from the fish species belonged to Weissella viridescens, which was isolated from three of the four species analyzed. None of the LAB species isolated from fish was found in sediments. The agar diffusion method was used for detection of antagonistic activity against Listeria monocytogenes, Yersinia ruckeri, Aeromonas salmonicida subsp. salmonicida and two strains of Lactococcus garvieae. All the isolates exhibited some degree of antagonistic activity against L. monocytogenes, Y. ruckeri and both strains of Lc. garvieae. Twelve strains were found to be inhibitory for A. salmonicida. This study is the first report on the diversity of lactic acid bacteria in a coastal marine environment and fish from Argentina. The sediments and fish analyzed showed microbial strains with the ability to suppress pathogen growth under in vitro conditions, suggesting their potential as biological control agents for aquaculture and fish processing.Este estudio analiza la biodiversidad de bacterias del ácido láctico presentes en el estuario de Bahía Blanca y su actividad antimicrobiana frente a patógenos relacionados con el cultivo de salmónidos. Se aislaron 21 cepas de bacterias del ácido láctico a partir de peces y sedimentos del estuario. Las especies de peces fueron seleccionadas entre aquellas que habitan la mayor parte de su ciclo en el estuario. De acuerdo al análisis de la secuencia 16S ADNr, los aislamientos correspondieron a los géneros Lactobacillus, Pediococcus, Leuconostoc, Enterococcus y Weissella. La especie predominante en los aislamientos obtenidos de peces fue Weissella viridescens, la cual fue aislada de tres de las cuatro especies de peces estudiados. Ninguna de las especies aisladas de los peces fue encontrada en los sedimentos. El método de difusión en agar se empleó para detectar la actividad antimicrobiana de las cepas aisladas frente a patógenos de salmónidos: Yersinia ruckeri, Aeromonas salmonicida subsp. salmonicida, y dos cepas de Lactococcus garvieae, y frente a Listeria monocytogenes. Todas las cepas mostraron algún grado de inhibición frente a L. monocytogenes, Y. ruckeri and Lc. garvieae. Doce cepas mostraron actividad frente a A. salmonicida. Este estudio es el primer reporte sobre la diversidad de bacterias del ácido láctico en un ambiente marino costero y en peces de la Argentina. Las cepas de bacterias del ácido láctico obtenidas de peces y sedimentos con capacidad de inhibir in vitro los patógenos estudiados podrían tener aplicación en el control biológico en acuicultura y en la industria procesadora de pescado.Fil: Sica, María Gabriela.

ClC-1 mutations in myotonia congenita patients: insights into molecular gating mechanisms and genotype-phenotype correlation

Loss-of-function mutations of the skeletal muscle ClC-1 channel cause myotonia congenita with variable phenotypes. Using patch clamp we show that F484L, located in the conducting pore, probably induces mild dominant myotonia by right-shifting the slow gating of ClC-1 channel, without exerting a dominant-negative effect on the wild-type (WT) subunit. Molecular dynamics simulations suggest that F484L affects the slow gate by increasing the frequency and the stability of H-bond formation between E232 in helix F and Y578 in helix R. Three other myotonic ClC-1 mutations are shown to produce distinct effects on channel function: L198P shifts the slow gate to positive potentials, V640G reduces channel activity, while L628P displays a WT-like behaviour (electrophysiology data only). Our results provide novel insight into the molecular mechanisms underlying normal and altered ClC-1 function

Developing the islamic financial services sector in Italy: An institutional theory perspective

© The Editor(s) (if applicable) and the Author(s) 2016. The Islamic Financial Services (IFS) sector has experienced wider consumer acceptance and rapid growth since its commercial launch in the 1970s. This growth has primarily been in countries in Asia such as Iran, Malaysia, Pakistan and the Middle East region. Although non-Muslim majority countries like Hong Kong and Singapore have taken positive strides in developing the sector, European countries have lagged behind their Asian counterparts (Daily Times, 2013). Europe is host to a large Muslim population, but the lack of developed Islamic financial institutions means that the potential of IFS product offerings is yet to be fully realized in the region (Volk and Pudelko, 2010)

The clinical utility of molecular diagnostic testing for primary immune deficiency disorders: a case based review

Primary immune deficiency disorders (PIDs) are a group of diseases associated with a genetic predisposition to recurrent infections, malignancy, autoimmunity and allergy. The molecular basis of many of these disorders has been identified in the last two decades. Most are inherited as single gene defects. Identifying the underlying genetic defect plays a critical role in patient management including diagnosis, family studies, prognostic information, prenatal diagnosis and is useful in defining new diseases. In this review we outline the clinical utility of molecular testing for these disorders using clinical cases referred to Auckland Hospital. It is written from the perspective of a laboratory offering a wide range of tests for a small developed country

The primary headaches: genetics, epigenetics and a behavioural genetic model

The primary headaches, migraine with (MA) and without aura (MO) and cluster headache, all carry a substantial genetic liability. Familial hemiplegic migraine (FHM), an autosomal dominant mendelian disorder classified as a subtype of MA, is due to mutations in genes encoding neural channel subunits. MA/MO are considered multifactorial genetic disorders, and FHM has been proposed as a model for migraine aetiology. However, a review of the genetic studies suggests that the FHM genes are not involved in the typical migraines and that FHM should be considered as a syndromic migraine rather than a subtype of MA. Adopting the concept of syndromic migraine could be useful in understanding migraine pathogenesis. We hypothesise that epigenetic mechanisms play an important role in headache pathogenesis. A behavioural model is proposed, whereby the primary headaches are construed as behaviours, not symptoms, evolutionarily conserved for their adaptive value and engendered out of a genetic repertoire by a network of pattern generators present in the brain and signalling homeostatic imbalance. This behavioural model could be incorporated into migraine genetic research

Epidemiology, practice of ventilation and outcome for patients at increased risk of postoperative pulmonary complications

BACKGROUND Limited information exists about the epidemiology and outcome of surgical patients at increased risk of postoperative pulmonary complications (PPCs), and how intraoperative ventilation was managed in these patients. OBJECTIVES To determine the incidence of surgical patients at increased risk of PPCs, and to compare the intraoperative ventilation management and postoperative outcomes with patients at low risk of PPCs. DESIGN This was a prospective international 1-week observational study using the ‘Assess Respiratory Risk in Surgical Patients in Catalonia risk score’ (ARISCAT score) for PPC for risk stratification. PATIENTS AND SETTING Adult patients requiring intraoperative ventilation during general anaesthesia for surgery in 146 hospitals across 29 countries. MAIN OUTCOME MEASURES The primary outcome was the incidence of patients at increased risk of PPCs based on the ARISCAT score. Secondary outcomes included intraoperative ventilatory management and clinical outcomes. RESULTS A total of 9864 patients fulfilled the inclusion criteria. The incidence of patients at increased risk was 28.4%. The most frequently chosen tidal volume (VT) size was 500 ml, or 7 to 9 ml kg1 predicted body weight, slightly lower in patients at increased risk of PPCs. Levels of positive end-expiratory pressure (PEEP) were slightly higher in patients at increased risk of PPCs, with 14.3% receiving more than 5 cmH2O PEEP compared with 7.6% in patients at low risk of PPCs (P < 0.001). Patients with a predicted preoperative increased risk of PPCs developed PPCs more frequently: 19 versus 7%, relative risk (RR) 3.16 (95% confidence interval 2.76 to 3.61), P < 0.001) and had longer hospital stays. The only ventilatory factor associated with the occurrence of PPCs was the peak pressure. CONCLUSION The incidence of patients with a predicted increased risk of PPCs is high. A large proportion of patients receive high VT and low PEEP levels. PPCs occur frequently in patients at increased risk, with worse clinical outcome
