UC 38, a simple analog of oxathiin carboxanilide, UC 84, lacking the oxathiin ring, was found to be a potent inhibitor of human immunodeficiency virus (HIV)-1-induced cell killing and HIV replication in a variety of human cell lines, as well as in human peripheral blood lymphocytes and macrophages. UC 38 was active against a wide range of biologically diverse laboratory and clinical strains of HIV-1. However, UC 38 was inactive against HIV-2 and both nevirapine- and pyridinone-resistant strains of HIV-1. UC 38 selectively inhibited HIV-1 reverse transcriptase (RT), but not HIV-2 RT. Combination of UC 38 with 3-azido-3-deoxythymidine synergistically inhibited HIV-induced cell killing. An HIV-1 isolate resistant to UC 38 was selected in cell culture, and the mutations in the RT nucleotide sequences were determined. Comparison with the wild-type RT sequence revealed an amino acid change at position 181 (Tyr to Cys). The UC 38-resistant virus was found to be cross-resistant to a variety of ...

XTT assay is a colorimetric method that uses the tetrazolium dye, 2,3-bis-(2-methoxy-4-nitro-5-sulphenyl)-(2H)-tetrazolium-5-carboxanilide (XTT) to quantify cell-mediated damage to fungi. Actively respiring fungal cells convert the water-soluble XTT to a water-soluble, orange colored formazan product (Meshulam et al., 1995). Here, we describe the protocol that measures the ability of plasmacytoid dendritic cells (pDCs) to exert antifungal activity. This approach was first established with human polymorphonuclear cells (PMN) by Meshulam et al. (1995) and then adapted to pDC by Ramirez-Ortiz et al. (2011) and Loures et al. (2015). It can be modified for use with other effector cells and to test compounds for antifungal activity., XTT测定是使用四唑鎓染料，2,3-双 - （2-甲氧基-4-硝基-5-磺酰基） - （2H） - 四唑鎓-5-甲酰苯胺（XTT）定量细胞介导的损伤的比色法 到真菌。 主动呼吸真菌细胞将水溶性XTT转化为水溶性橙色甲an产物（Meshulam等人

Background Thuricin CD is a two-component antimicrobial, belonging to the recently designated sactibiotic subclass of bacteriocins. The aim of this study was to investigate the effects of thuricin CD, as well as the antibiotics, tigecycline, vancomycin, teicoplanin, rifampicin and nitazoxanide when used independently and when combined at low concentrations on the viability of Clostridium difficile 20291 R027, TL178 R002, Liv022 R106, DPC6350 and VPI10463 biofilms and planktonic cells. Results On the basis of XTT (2,3-bis[2-methyloxy-4-nitro-5-sulphophenyl]-2H-tetrazolium-5-carboxanilide)-menadione biofilm viability assays, we found that thuricin CD was effective against biofilms of R027, Liv022 R106 and DPC6350 when used independently while nitazoxanide and rifampicin were also potent against biofilms of R027 and DPC6350, when applied on their own. Tigecycline was found to be effective against R027 and DPC6350 biofilms, whereas teicoplanin and vancomycin when used independently were only ...

Succinate dehydrogenase (Sdh) inhibitor fungicides, such as boscalid, are effective for the management of gray mold caused by the fungal pathogen Botrytis cinerea. Unfortunately, resistance to boscalid was common among isolates of the pathogen from small fruits grown in Oregon. Boscalid-resistance is commonly associated with mutations in Sdh, especially in subunit B. SdhB was sequenced from five boscalid-sensitive and five boscalid-resistant isolates of B. cinerea. A majority of the boscalid-resistant isolates had a single nucleotide polymorphism at codon 272 resulting in a substitution of histidine with arginine (H272R). The boscalid-sensitive isolates did not harbor this mutation. The transposons Boty and Flipper also were found within the genomes of the resistant strains, but not boscalid-sensitive isolates. Additionally, a pattern was found to exist between the transposons present within the strains and source location. Additional studies with a greater number of isolates are required to ...

Micafungin (MFG) demonstrates potent activity against biofilms of Candida albicans and Candida parapsilosis, the most frequent opportunistic fungal pathogens. Little is known about its immunopharmacologic effect on antibiofilm activity of phagocytic cells following exposure to Candida biofilms. In this study, we investigated the effects of MFG on human neutrophil-mediated damage of C. albicans and C. parapsilosis biofilms by XTT [2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide] and the potential mechanisms underlying the immunomodulatory MFG activities on cultured monocyte-derived THP-1 cells in response to these biofilms by reverse transcription-PCR and sandwich and multiplex enzyme-linked immunosorbent assay. Preexposure of C. albicans to subinhibitory MFG concentrations significantly enhanced neutrophil-mediated biofilm damage, an effect that appears to be species specific since a comparable effect was not observed with drug-pretreated C. parapsilosis biofilms. Human ...

Background: Methyl-thiophanate (MT), a fungicide largely used in agriculture throughout the world including Tunisia, protects many vegetables, fruits and field crops against a wide spectrum of fungal diseases. Oxidative stress has been proposed as a possible mechanism involved in MT toxicity on non-target organism.. Methods: In the present study, the effect of MT injected intraperitoneally to adult rats at 300 or 500 mg/kg of body weight was studied on blood, liver and kidney.. Results: Our results showed 3 days after MT injection, a significant decrease in hemoglobin and hematocrit values. A disruption in total white blood cells and platelets also occurred. Accordingly, an increased in malondialdehyde, H2O2 and advanced oxidation protein levels in liver and kidney were noted with the two doses. A significant change in plasma biomarkers and organ enzymatic and non-enzymatic activities were observed after MT treatment. The modifications in biochemical parameters were substantiated by ...

1. Fungicides. Learn the difference between a contact (protectant) fungicide and a systemic fungicide. Although a glossary may help, the index in your textbook may guide you to good descriptions in the text.. 2. Biological control. Learn that biocontrol agents often interfere with pathogen activity by one or more of the following mechanisms: (1) parasitism of the pathogen, (2) competition with the pathogen for nutrients or other resources, (3) excretion of toxic substances or (4) induction of host resistance. For students with access to Agrios (1), read about Mechanism of Action on p. 307 and view the images in Figures 9-7 through 9-13.. 3. Host resistance. Learn what phytoalexins are (just a general working definition, not specifics about particular phytoalexins); the glossary and index of your text may serve as a guide to appropriate information. Although plants produce many types of biochemical defense mechanisms, phytoalexins will serve as a good example. Also learn that plants sometimes ...

Signs of Pytophthora crown rot and stem canker are wilting, decline and plant death although a fairly healthy root system may be present.. Phytophthora like Pythium is a a lower fungus favored by excess moisture and excess nitrogen fertility. Unlike Pythium, species of Phytophthora are more aggressive, more likely to be host specific, and less frequently found in greenhouses. The most likely source of origin is plant material.. Start with soilless growing media and avoid contaminating media with soiled hands, tools, or containers. Promptly remove diseased plants, avoid splashing water when irrigating and keep hose ends off the floor. The best means for controlling Phytophthora is with drenches of systemic fungicides which will move up into the crown area such as mefenoxam (Subdue Maxx), foestyl-Al (Aliette) azoxystrobin (Heritage), or phosphonate-Al (ProPhyt). Check label for crop appropriateness. Rotate fungicides to prevent resistance development.. ...
