SIC: a novel selective medium for the primary isolation of in veterinary samples.

Brucellosis, a re-emerging zoonotic infection, threatens animal welfare and public health with serious economic consequences. A definitive diagnosis requires Brucella isolation by culturing field specimens in specific media. This study aimed to (i) assess the effectivity of recommended Farrell's médium (FM) and CITA medium (CM) for the isolation of four Brucella melitensis strains (16M, Rev1, and the 16MΔ and Rev1Δ in-frame deletion mutants) with variable susceptibility to polymyxins; (ii) develop a Brucella selective medium (BSM) suitable for these strains; (iii) test BSM, FM, and CM with other Brucella species; and (iv) develop an improved selective culture medium (SIC) for all brucellae, including B.

Wzm/Wzt System: Changes in the Bacterial Envelope Lead to Improved Rev1Δ Vaccine Properties.

The lipopolysaccharide (LPS) O-polysaccharide (O-PS) is the main virulence factor in . After synthesis in the cytoplasmic membrane, O-PS is exported to the periplasm by the Wzm/Wzt system, where it is assembled into a LPS. This translocation also engages a bactoprenol carrier required for further biosynthesis pathways, such as cell wall biogenesis.

Prematurity and Low Birth Weight in Neonates as a Risk Factor for Obesity, Hypertension, and Chronic Kidney Disease in Pediatric and Adult Age.

Low weight at birth may be due to intrauterine growth restriction or premature birth. Preterm birth is more common in low- and middle-income countries: 60% of preterm birth occur in sub-Saharan African or South Asian countries. However, in some higher-income countries, preterm birth rates appear to be increasing in relation to a reduction in the lower threshold of fetal viability.

Prevalence of in Free-Range Pigs: Risk Factors and Intestinal Microbiota Composition.

Extensive pig systems are gaining importance as quality production systems and as the standard for sustainable rural development and animal welfare. However, the effects of natural foods on epidemiology remain unknown. Herein, we assessed the presence of and the composition of the gut microbiota in pigs from both -free and high prevalence farms.

Genotyping Study of 4,[5],12:i:- Monophasic Variant of Serovar Typhimurium and Characterization of the Second-Phase Flagellar Deletion by Whole Genome Sequencing.

After Enteritidis and Typhimurium, 4,[5],12:i:- is the most reported serovar in human clinical cases. During the past 20 years, many tools have been used for its typing and second-phase flagellar deletion characterization. Currently, whole genome sequencing (WGS) and different bioinformatic programs have shown the potential to be more accurate than earlier tools.

Phage Lytic Protein LysRODI Prevents Staphylococcal Mastitis in Mice.

Phage lytic proteins are promising antimicrobials that could complement conventional antibiotics and help to combat multi-drug resistant bacteria that cause important human and animal infections. Here, we report the characterization of endolysin LysRODI (encoded by staphylophage phiIPLA-RODI) and its application as a prophylactic mastitis treatment. The main properties of LysRODI were compared with those of endolysin LysA72 (encoded by staphylophage phiIPLA35) and the chimeric protein CHAPSH3b (derived from the virion-associated peptidoglycan hydrolase HydH5 and lysostaphin).

The aim of this study was to evaluate the potential use of an e-nose in combination with lateral flow immunoassays for rapid aflatoxin and fumonisin occurrence/co-occurrence detection in maize samples. For this purpose, 161 samples of corn have been used. Below the regulatory limits, single-contaminated, and co-contaminated samples were classified according to the detection ranges established for commercial lateral flow immunoassays (LFIAs) for mycotoxin determination.

The presence of mutated and deleted PTEN is associated with an increased risk of relapse in childhood T cell acute lymphoblastic leukaemia treated with AIEOP-BFM ALL protocols.

Notwithstanding the improvement in treatment results for paediatric T cell acute lymphoblastic leukaemia (T-ALL) it remains important to understand if genetic aberrations influence therapy response. PTEN tumour suppressor gene inactivation is a frequent event in T-ALL but its effect on patient therapy response is debatable. We analysed the effect of the presence of mutated PTEN on outcome in 257 children with T-ALL treated with Associazione Italiana di Ematologia e Oncologia Pediatrica (AIEOP)-Berlin-Frankfürt-Münster (BFM) protocols.

Multidrug resistant Salmonella enterica isolated from conventional pig farms using antimicrobial agents in preventative medicine programmes.

A longitudinal study was conducted to investigate the presence of multidrug antimicrobial resistance (multi-AR) in Salmonella enterica in pigs reared under conventional preventative medicine programmes in Spain and the possible association of multi-AR with ceftiofur or tulathromycin treatment during the pre-weaning period. Groups of 7-day-old piglets were treated by intramuscular injection with ceftiofur on four farms (n=40 piglets per farm) and with tulathromycin on another four farms (n=40 piglets per farm). A control group of untreated piglets (n=30 per farm) was present on each farm.

Transcatheter aortic valve implantation versus surgical aortic valve replacement in patients over 85 years old.

Objectives: Surgical aortic valve replacement (SAVR) for the treatment of in very old patients with severe aortic stenosis is associated with a high risk of morbidity and mortality. Transcatheter aortic valve implantation (TAVI) has become the preferred alternative. Therefore, we sought to evaluate outcomes in very old patients who underwent SAVR versus TAVI.

Short and long-term outcome in very old patients with ST-elevation myocardial infarction after primary percutaneous coronary intervention.

Diabetes education in primary care: a randomized clinical trial.

The aim of the study was to evaluate the effect of a structured group education program administered by a primary care nurse in patients with type 2 diabetes mellitus. The sample included 137 patients with type 2 diabetes mellitus, randomized into two groups: intervention (5-week educational course and reinforcements every 4 months for one year) and control (with no structured diabetes mellitus education) with an evaluation of metabolic control, weight, blood pressure, distress scores, and knowledge on diabetes. There were no differences between the two groups in HbA1c at 4, 8, or 12 months when compared to baseline values.

Brucella abortus depends on pyruvate phosphate dikinase and malic enzyme but not on Fbp and GlpX fructose-1,6-bisphosphatases for full virulence in laboratory models.

The brucellae are the etiological agents of brucellosis, a worldwide-distributed zoonosis. These bacteria are facultative intracellular parasites and thus are able to adjust their metabolism to the extra- and intracellular environments encountered during an infectious cycle. However, this aspect of Brucella biology is imperfectly understood, and the nutrients available in the intracellular niche are unknown.

Hypertension management algorithm for type 2 diabetic patients applied in primary care.

Background: Hypertension frequently coexists with type 2 diabetes (DM), and increases the risk of cardiovascular outcomes. The aim of the study was to obtain/maintain blood pressure (BP) goals (ADA/JNC 7) according to a stepwise algorithm using the medication supplied by the Brazilian government.

Methods: A one-year, single-arm interventional study conducted with type 2 diabetes patients.

Relative contributions of lipooligosaccharide inner and outer core modifications to nontypeable Haemophilus influenzae pathogenesis.

Nontypeable Haemophilus influenzae (NTHi) is a frequent commensal of the human nasopharynx that causes opportunistic infection in immunocompromised individuals. Existing evidence associates lipooligosaccharide (LOS) with disease, but the specific and relative contributions of NTHi LOS modifications to virulence properties of the bacterium have not been comprehensively addressed. Using NTHi strain 375, an isolate for which the detailed LOS structure has been determined, we compared systematically a set of isogenic mutant strains expressing sequentially truncated LOS.

Effect of different types of self-management education in patients with diabetes.

Education plays an important role in diabetes mellitus (DM) treatment, as it enables patients to manage their disease. There is a wide range of tested educational interventions, and, to date, no universal model that can be standardized and recognized as effective for all individuals with the disease has been defined. This article aims to review the effect of different types of educational interventions for self-management of glycemic control in patients with DM type 2, in addition to define general recommendations for this treatment strategy.
