    Abstract Here, the microstructure and mechanical properties of a basalt with three alteration degrees (low, medium, and high) are studied, and these properties are compared to the alteration degree of the basalt. The representative samples of each alteration degree have been studied both in raw state as after a short ageing treatment with ethylene glycol. The properties studied are density, P-wave velocity (VP) and uniaxial compression strength (UCS). The microstructure has been studied via optical and scanning electron microscopy and X-ray computed microtomography (microCT), which also provides quantitative data on connected and non-connected porosity. The representative samples of the three alteration degrees show clear differences and Vₚ and UCS values are progressively lower as higher the alteration. The loss of the good properties of low altered basalt was due to smectites filling a dense network of micro- and nano-fractures that crossed the full rock. Smectites as alteration products of the basalt explained the behaviour of these rocks. With only three swelling–shrinking cycles of smectites, the porosity grew ~500% in the most altered sample, which explains the cohesion loss of the rock and its lower UCS. Statistical analysis showed the negative correlation among the connected porosity and the mechanical properties of these basalts.

    Abstract Background: Although salmonellosis is considered one of the most important food-borne zoonotic diseases in Europe, close contact between dogs and their owners can also be a potential source of Salmonella spp. for humans. This study assessed the prevalence and antimicrobial resistance of Salmonella spp. in apparently healthy dogs in the Valencian Region, eastern Spain. Moreover, a macroscopic comparison of lactic acid bacteria in both Salmonella-positive and Salmonella-negative dogs was carried out.
    Results: Of a total of 325 dogs sampled, 6 (1.85%) were positive for Salmonella spp. with 3 different serotypes, Havana (3), Mikawasima (2) and monophasic Typhimurium (1). All isolates were susceptible to all antimicrobials tested except monophasic S. Typhimurium, which was resistant to ampicillin. Finally, macroscopic results revealed that lactic acid bacteria had higher heterogeneity in the Salmonella-negative dogs than in the Salmonella-positive dogs. Although the results in our study showed a low prevalence of Salmonella spp., raw food has been suggested as a risk factor for bacteria in dog faeces.
    Conclusions: Public awareness campaigns on good hygiene practices, especially after handling canine faeces or raw food, are necessary. Furthermore, to reduce the potential transmission of bacteria, dogs should be fed food that has been properly cooked, as raw or undercooked food can be a source of zoonotic pathogens. Moreover, further studies must be performed to determine the relationship between lactic acid bacteria and Salmonella spp. in dog faeces.

    Abstract Mastitis is a significant disease in dairy ruminants, causing economic losses to the livestock industry and severe risks to public health. Antibiotic therapy is one of the most crucial practices to treat mastitis, although the susceptibility of caprine mastitis pathogens to current antibiotics has not been tested under standard or modified incubation conditions. This work evaluated the in vitro activity of tildipirosin, gamithromycin, oxytetracycline, and danofloxacin against caprine mastitis pathogens incubated following standard conditions of Clinical and Laboratory Standards Institute (CLSI) and deviation method by 25% supplementation with goat serum. Mycoplasma agalactiae, Escherichia coli, Staphylococcus aureus, Streptococcus spp., and coagulase-negative Staphylococci (CNS) were isolated from dairy goats with mastitis in Spain. Minimum inhibitory concentrations (MICs) were determined using the broth microdilution technique. The lowest MIC

    Abstract This paper describes the results that have been obtained in a real case study of a hybrid constructed wetlands system, which has been in continuous operation for over 11 years. The main aim of the study was to understand the long-term operation and efficiency of the system (which is situated in the municipality of Santa Lucía, Gran Canaria, Spain), which comprises two vertical-flow and one horizontal-flow constructed wetlands for the treatment of urban wastewater. The system, which was originally designed to treat a flow rate of 12.5 m

    Abstract Of all the abiotic stress types to which plants grown in fields are exposed, the most influential is water stress. It is well accepted that adopting controlled deficit irrigation strategies during the growing season has beneficial effects on the chemical compositions of grapes and red wines. However, there is a discrepancy in the timing, intensity and duration of deficit. This study aimed to evaluate the changes in phenolic composition of ‘merlot’ cultivar grapes when subjected to different levels of water stress in a semi-arid Mediterranean climate. Four treatments with different water stress levels were applied within two phenological intervals (flowering-veraison, veraison-maturity) to 128 grapevines for two consecutive years. The water stress levels for Treatments 1, 2, 3 and 4 were: no-light, light-moderate, moderate-intense and intense for the flowering-veraison and veraison-maturity intervals, respectively. Water stress distinctly affected the phenolic compounds in skin and seeds. The concentrations of flavan-3-ols and total polyphenols were much higher in seeds than in skin, and in both fractions, tannins are the major compounds.

    Abstract Background: The treatment of tuberculosis (TB) in solid organ transplant (SOT) recipients is challenging owing to interactions between rifampin and immunosuppressive drugs. Rifabutin, a rifamycin with excellent activity against Mycobacterium tuberculosis and that induces cytochrome p450 less, may facilitate treatment. We report our experience with rifabutin for treating TB in SOT recipients and review the available literature.
    Methods: A retrospective observational study of all SOT recipients with TB between January 2000 and December 2019. The clinical characteristics and outcomes of patients treated with and without rifabutin-containing regimens were compared and a literature review was conducted.
    Results: We included 31 SOT recipients with TB, among whom 22 (71%) were men and the median age was 62 years (interquartile range 50-20). There were no significant differences between patients treated with rifabutin (n = 12), rifampin (n = 14), and non-rifamycins (n = 5) in clinical cure rates (83.3%, 64.3%, and 100%, respectively; P = .21), side effects (25%, 37.5%, and 20%, respectively; P = .74), or mortality (16.7%, 35.7%, and 0%, respectively; P = .21). Only one patient, treated with rifampin, suffered graft rejection. The literature review identified 59 SOT recipients with TB treated with rifabutin-containing regimens from 8 publications. Overall, the clinical cure, graft rejection, and mortality rates were 93.2%, 5.1%, and 6.8%, respectively.
    Conclusions: Rifabutin-containing regimens offer a reliable alternative to rifampin when treating TB in SOT recipients.
