ABSTRACT: This study evaluated Lacticaseibacillus casei CB054 (Lsc.CB054) from anaerobically fermented bovine colostrum for its in vitro probiotic potential. We performed a series of tests to verify the capacity and safety bacterial isolate. These included evaluation hemolytic capacity, cytotoxicity, antimicrobial susceptibility, tolerance adverse conditions, survival gastrointestinal tract, antagonistic activity against pathogenic bacteria, auto- co-aggregation abilities. The results...
Pythium insidiosum belongs to the phylum Oomycota. It is capable of infecting mammals causing a serious condition called pythiosis, which affects mainly horses in Brazil and humans Thailand. The objective present study was verify vitro anti-P. activity biogenic silver nanoparticle (bio-AgNP) formulation. assays were evaluated on P. isolates (n = 38) following M38-A2 protocol. Damage hyphae ultrastructure verified by means scanning electron microscopy (SEM) transmission (TEM). Bio-AgNP...
Abstract Pythiosis is a rapidly progressing disease that can be lethal to affected individuals due resistance available therapeutic protocols. The affects mammals, with the largest number of reports in horses and humans. present study investigated activity biogenic silver nanoparticles (bioAgNP) treatment experimental pythiosis. was reproduced nine female 90-day-old New Zealand rabbits. Animals were divided into three groups: group1 (control, n = 3) daily topically treated nonionized...
The aim of this study was to investigate the in vitro susceptibility Pythium insidiosum combinations antifungal drugs terbinafine or itraconazole with Melaleuca alternifolia, Mentha piperita and Origanum vulgare essential oils (EOs).In EOs were evaluated by checkerboard microdilution method against 20 Brazilian isolates P. insidiosum. tests performed according protocol M38-A2, interpretation each combination result based on values fractional inhibitory concentration index. presented...
RESUMO: Foram coletadas 186 amostras de água ambientes pantanosos em 13 municípios das regiões Sul, Central e Oeste do Rio Grande Brasil, com o objetivo isolar caracterizar espécies Pythium avaliar a sua patogenicidade empregando coelhos como modelo experimental. Em 11,8% (n=22) águas foram isoladas diferentes incluindo: P. insidiosum (n=1), catenulatum (n=3), pachycaule voucher rhizo-oryzae torulosum (n=4) spp. (n=10). Zoósporos desses micro-organismos produzidos in vitro inoculados por via...
Abstract Background Maintaining mosquito colonies in the laboratory requires a blood supply so that females' oocytes can mature and oviposition take place. In this study, new artificial hematophagy system for colonization maintenance of Culex quinquefasciatus was developed tested. Methods We an attractive polymeric biofilm including 25% l -lactic acid use as membrane compared feeding rate females with Parafilm-M ® . also evaluated rate, larval survival adult emergence fed through biofilm....
ABSTRACT: Pythium insidiosum is an important oomycete pathogen of mammals that causes pythiosis, endemic disease in warm climates stands out for its unfavorable prognosis, lethality the affected species, and difficulties treatment. This study evaluated vitro anti-P. potential aqueous, hydroethanolic, ethanolic extracts indigenous wild mushrooms from southern Brazil. The were prepared Amanita gemmata, muscaria, Auricularia auricula, Gymnopilus junonius, Lactarius deliciosus, Laccaria laccata,...
ABSTRACT: This study evaluated the inhibitory effect of ozone gas (O3) on mycelia and zoospores Pythium insidiosum verified morphological changes it caused hyphae. The effects O3 were (n = 21) 10) P. insidiosum. was bubbled into vials with sterile distilled water mycelium or induction medium zoospores. After 15 minutes, aliquots grown yeast agar at 37 °C/96 hours. Ozonated flasks incubated ºC/72 hours; every 24 hours, subcultured ºC/96 Transmission (TEM) scanning (SEM) electron microscopy...
Abstract The study evaluated the ovicidal activity of enzymatic extracts Purpureocillium lilacinum and Trichoderma virens against trichostrongylid eggs from sheep. Filtered extract (FE) macerated crude (MCE) were prepared fungal cultures in minimal broth. In experiment, 100 eggs, obtained feces naturally infected sheep, exposed to for 24 48 hours/25°C. control group, incubated number L1 larvae was ascertained. Each treatment consisted four repetitions experiment repeated five times. It...
O colostro equino fornece imunoglobulinas, nutrientes e fatores de crescimento essenciais à imunidade sobrevivência do potro neonato. No entanto, em inúmeros casos a ingestão pelo neonato não ocorre forma natural, sendo necessário o aleitamento artificial. Todavia, métodos preservação têm gerado resultados controversos. objetivo deste estudo foi elaborar uma técnica fermentação anaeróbica fim preservar qualidade produto avaliar in vitro manutenção dos constituintes colostrais. Foram...
Abstract Background: Maintaining mosquito colonies in the laboratory implies need for a blood supply so that females can mature their oocytes and perform oviposition. In this study, new artificial hematophagy system colonization maintenance of Cx quinquefasciatus laboratory, was developed tested. Methods: We an attractive polymeric biofilm with 25% L-lactic acid its composition, to be used as membrane compared feeding rate Parafilm - M®. also evaluated oviposition rate, larval survival,...
