Abstract
The use of antibiotics to prevent bovine mastitis is responsible for the emergence and selection of resistant strains. Lactic acid bacteria (LAB) could be introduced into animal feed as an alternative prevention method that would bypass the risk of resistance development. In previous research, we demonstrated that two probiotic LAB strains isolated from bovine milk were capable of stimulating the production of antibodies and the host's immune cellular response in the udder. The present study aimed to elucidate whether the antibodies of animals inoculated with these strains were able to increase phagocytosis by neutrophils and inhibit the growth of different mastitis-causing pathogens. Moreover, the effect of LAB on the expression of pro-inflammatory cytokines was assessed. Ten animals were inoculated intramammarily with 106 cells of the two strains at dry-off. The blood serum was tested for its ability to opsonize bovine mastitis pathogens, the in vitro bactericidal activity of bovine blood and milk against these pathogens was determined, and cytokine mRNA expression was quantified in milk somatic cells. The inoculated animals did not show abnormal signs of sensitivity to the LAB. Their blood serum significantly enhanced the phagocytosis of Staphylococcus spp. and the LAB. Escherichia coli and Streptococcus uberis were inhibited by the milk serum but not the blood serum, whereas Staphylococcus aureus and Staphylococcus haemolyticus were inhibited by both. In regard to cytokine expression, interleukin (IL)-1β increased markedly for up to 4 h post-inoculation, and an increase in IL-8 was observed 4, 12 and 24 h after inoculation. Tumour necrosis factor-α mRNA increased 1 and 2 h after inoculation and a significant difference was registered at 6 h for interferon-γ. This rapid immunomodulatory response shows that inoculating animals with LAB at dry-off, when they are especially susceptible, could be a useful strategy for the prevention of bovine mastitis.

Tetraglochin andina Ciald.: A medicinal plant from the Argentinean highlands with potential use in vaginal candidiasis. J Ethnopharmacol 2018; 216:283-294.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Argentinean medicinal plant Tetraglochin andina Ciald, formerly classified as T. cristatum (Britton) Rothm is used in traditional medicine by inhabitants from Argentinean northwestern highlands (Puna) to treat candidiasis and as anti-inflammatory. AIM OF THE STUDY To assess the potential of the crude drug as an anti-Candida agent with anti-inflammatory properties. The bioactivity and phytochemical composition of a dry extract of the plant was investigated. MATERIAL AND METHODS The pharmacognostic description of the crude drug is carried out for the first time, including macroscopic and microscopic examinations of the different organs, physicochemical and extractive values (petroleum ether-, ethanol- and water-soluble). The dry extract from T. andina was evaluated as antifungal against pathogenic Candida sp. and Saccharomyces cerevisiae isolated from vaginal infections and reference strains, by the macrodilution and microdilution assays. The normal vaginal microbiome in women is characterized by the dominance of lactic acid-producing bacteria, mainly Lactobacillus spp. The effect of T. andina extract on Lactobacillus strains was also assayed. The inhibitory effect on proinflammatory enzymes (cyclooxygenase, lipoxygenase and phospholipase A2) and antioxidant capacity was studied. The chemical profile was analyzed by HPLC-ESI-MS. RESULTS The hydroalcoholic extract inhibited the growth of all yeasts with Minimal Inhibitory Concentration (MIC) values between 12.5 and 400 µg GAE/mL and the MIC values on Lactobacillus were higher than the MIC values against Candida isolates ( > 400 µg GAE/mL). These results indicate that the hydroalcoholic extract could be used without affecting the normal microbiota of vaginal fluid. The extract showed antioxidant activity and could modulate the inflammatory process by three pathways (sPLA2, COX-2, LOX). The plant extract contained high total phenolic levels (386.9±1.7 mg GAE/g dry extract) and flavonoid levels (260.4±2.7 mg GAE/g dry extract). Fifty phenolic compounds were identified by HPLC-ESI-MS. They were mainly hydrolysable and condensed tannins. The dry extract was chemically and biologically stable during one year at room temperature or 4 °C. CONCLUSIONS The presence of anti-Candida and anti-inflammatory activities in Tetraglochin andina extracts give support to their traditional use for treating conditions associated with microorganism infections and inflammatory process in humans. This plant preparation could be used to design phytopharmaceutical preparations to inhibit yeast growth and moderate the inflammatory and oxidative process.
