Catnip essential oils have antimicrobial effects against bacteria, yeast, and fungi; however, there is limited information regarding their activity pathogens that cause canine skin infections. This study aimed to identify the phytochemical constituents of catnip oil assay its Staphylococcus pseudintermedius, Malassezia pachydermatis, Microsporum canis, gypseum, gallinae, Trichophyton mentagrophytes. was extracted by hydrodistillation, chemical were analyzed gas chromatography-mass...
Helicobacter pylori (H. pylori) is a micro-aerophilic, spiral-shaped, motile bacterium that the principal cause of gastric and duodenal ulcers in humans major risk factor for development cancer. Despite provoking strong innate adaptive immune response host, H. persists mucosa, avoiding eradication by macrophages other phagocytic cells, which are recruited to site infection. Here we have characterised critical degradative process phagosome maturation primary human five genotypically...
Background and Aim: Microsporum gallinae is the major dermatophyte species that causes avian dermatophytosis. Disinfection plays an important role in controlling preventing dermatophytosis; however, information about effect of common disinfection processes on M. limited. This study aimed to investigate efficacy ultraviolet (UV) irradiation, heat treatment, detergents, germicides against infective spores (arthroconidia) vegetative mycelia gallinae. Materials Methods: The minimum inhibitory...
Abstract Background: Helicobacter pylori infection is an important health problem, as it involves approximately 50% of the world's population, causes chronic inflammatory disease and increases risk gastric cancer development. H. elicits a vigorous immune response, but this does not usually result in bacterial clearance. We have investigated whether persistence host could be partly due to inability macrophages kill bacterium. Materials Methods: Monocytes isolated from peripheral blood normal...
The development of new antimicrobial formulations for the treatment animal infectious dermatitis is important as current treatments can have undesirable effects.The purpose this study was to examine in vitro activity an Eryngium foetidum L. ethanolic extract against a bacterium, Staphylococcus pseudintermedius; yeast, Malassezia pachydermatis; and three dermatophytes, Microsporum canis, gypseum, Trichophyton mentagrophytes; all which are most common skin pathogens causing dermatitis.A...
Mastitis is an essential issue in dairy cows. Post-milking teat dips can help reduce this problem, but they employ harsh disinfectants, and many bacteria are becoming increasingly tolerant. This study aimed to investigate the antibacterial activity of clove, citronella, sweet basil oils against common bovine mastitis causative agents Staphylococcus aureus, Streptococcus agalactiae, Escherichia coli develop antiseptic post-milking spray for use The vitro antimicrobial was determined by broth...
Background and Aim: Mosquitoes carry numerous diseases of medical veterinary significance. While citronella essential oil is safe as a mosquito repellent, extensive research does not document its ability to deter mosquitoes from animals. This study assessed the bath bomb’s repel Culex quinquefasciatus in dogs. Materials Methods: Citronella oil’s chemical composition was analyzed using gas chromatography-mass spectrometry (GC-MS). Through freeze-thaw testing, bomb formulation containing 6%...
ABSTRACT We investigated the in vitro postantibiotic effects (PAEs) of ketolides telithromycin (HMR 3647) and HMR 3004 analyzed results using sigmoid E max model. Mean maximum PAEs against erythromycin A-susceptible strains Staphylococcus aureus , Streptococcus pyogenes pneumoniae were 3.7, 8.9, 9.7 h, respectively, while for A-resistant much shorter. 3.2 to 4.4 h all species.
Abstract Background In cases of non‐infectious diarrhoea in children, the WHO and Thai Antibiotic Smart Use ( ASU ) project recommend that no antibiotics should be given drinking water replaced with oral rehydration salt ORS solution until is finished. Aim To survey dispensing pattern for treatment children Thailand. Methods Simulated clients visited 91 Class I community pharmacies five districts Khon Kaen province asked advice to treat a 14‐month‐old child. The patient history questions by...
Superficial bacterial skin infections caused by Staphylococcus pseudintermedius are common in dogs.The cannabis plant has shown potential antibacterial effects, but there is limited information about anti-S.pseudintermedius activity.This study investigated the activity of ethanolic extract and topical formulations Cannabis sativa L. subsp.indica (Lam.) against 23 S. isolates obtained from canine pyoderma using broth microdilution time-kill assays.The extract's minimum inhibitory...
Helicobacter pylori infection can lead to the development of gastritis, peptic ulcers and gastric cancer, which makes this bacterium an important concern for human health. Despite evoking a strong immune response in host, H. persists, requiring complex antibiotic therapy eradication. Here we have studied impact patient's serum on relation macrophage uptake, phagosome maturation, bacterial killing.Primary macrophages were infected vitro with both serum-treated control pylori. The ability...
With the aim of directing lanthanide complex uptake via mannose receptor, a first generation luminescent complexes has been developed with an α -D-mannose targeting motif. Four were produced to investigate photophysical properties and determine effect coordinated residue on emission intensity. The free hydroxyls quenched phosphorescence due their close proximity, though they did not bind centre as observed by q -values ≈ 1.0 for all between pH 3 10. Fluorescent was found vary significantly...
Avian favus (dermatophytosis) is a superficial mycosis caused by Microsporum gallinae in poultry. This disease an important problem poultry husbandry, but the standard antifungal treatment can leave drug residues farm products. The aim of this study was to compare efficacy clove essential oil ointment (3%, w/w) with commercially available ketoconazole cream (2%, for M. infection chickens. An vitro time-kill assay showed that reduced number viable ATCC 90749 99.99% within 1 hr. A randomized...
Elemental sulfur has been used for a long time to treat superficial mycoses in both medical and veterinary practices, but effective treatment requires high concentrations of sulfur. Encapsulation nanoparticles can potentially allow the delivery infections. Sulfur were synthesized from Catharanthus roseus extract sodium sulfide at various pH conditions (4, 6, 7). Particle identification characterizations performed by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM),...
The rise of antimicrobial resistance in veterinary medicine is a significant concern, particularly for pathogens responsible skin infections. Although Stevia rebaudiana Bertoni (stevia) has demonstrated effective properties, there limited research on its efficacy against animal pathogens. This study aimed to identify natural compounds stevia extract, develop topical spray formulation, and assess effectiveness six common bacterial fungal associated with aerial parts plants were extracted...
Opisthorchiasis which exerted by infection of Opisthorchis viverrini is strongly related to the incident cholangiocarcinoma (CCA) in many Southeast Asian countries northeastern Thailand. The O. primarily caused raw fish consumption, and repeated exposure liver fluke. Meanwhile, acetaminophen usually medicated relieve pain particularly people northeast Thailand.This study therefore aimed at investigating effects on pathogenesis hamsters for opisthorchiasis.There were 4 groups hamsters: i)...
