The present study evaluated the susceptibility of 27 clinical isolates Pythium insidiosum to caspofungin in vitro and correlated results with therapeutic response vivo rabbits experimental pythiosis.The macrodilution method was performed accordance CLSI document M38-A technique. Three reading criteria for MICs were adopted: MIC0, MIC1 MIC2 (100%, 90% 50% growth inhibition, respectively). minimum fungicidal concentration also determined. Ten inoculated viable P. zoospores divided into two...
Skin lesions in feline sporotrichosis usually present a high fungal burden, making cats an important source of infection. This study evaluated the burden and isolation skin during treatment with itraconazole (ITZ), combined or without potassium iodide (KI). Treatment-naïve culture-confirmed presenting ulcers were treated for up to 40 weeks oral ITZ alone (n = 74) KI 56). These submitted monthly sampling same lesion mycological culture cytopathology until healing twelve weeks. The was...
The present study investigated the in vitro and vivo interactions among azithromycin, clarithromycin, minocycline, tigecycline against Pythium insidiosum. In antimicrobial activities were determined by broth microdilution method accordance with CLSI document M38-A2, antibiotic assayed using checkerboard MIC format. efficacy was a rabbit infection model. geometric mean MICs of P. insidiosum were, respectively, 1.91, 1.38, 0.91, 0.79 μg/ml. By testing, all combinations resulted synergistic...
We evaluated the in vitro activities of voriconazole, itraconazole, and terbinafine against 30 clinical isolates Pythium insidiosum using a checkerboard macrodilution method. The combined activity plus itraconazole or voriconazole was synergic 17% strains. Antagonism not observed.
We describe here the in vitro activities of azithromycin, clarithromycin, minocycline, or tigecycline alone and combination with amphotericin B, itraconazole, terbinafine, voriconazole, anidulafungin, caspofungin, micafungin against 30 isolates oomycete Pythium insidiosum. The assays were based on CLSI M38-A2 technique checkerboard microdilution method. main synergisms observed through minocycline B (73.33%), itraconazole (70%), (70%) clarithromycin (73.33%).
Malassezia pachydermatis is considered an opportunistic pathogen of the outer ear duct in dogs and cats. This yeast can also be found skin, rectum, anal sacks vagina. Eighty-two samples this isolated from with symptoms external otitis Porto Alegre region were tested for their susceptibility to antifungal agents using Broth Microdilution Method. The testing Ketoconazole, Fluconazole Itraconazole. Experimental essays determined that Sabouraud dextrose broth supplemented 1% Tween 80 was most...
ABSTRACT This study evaluated the in vitro activity of aminoglycoside antibiotics and tigecycline against Pythium insidiosum . The susceptibility tests were carried out using broth microdilution method accordance with CLSI document M38-A2. MIC values for gentamicin, neomycin, paromomycin, streptomycin ranged from 32 to 64 mg/liter, minimal fungicidal concentration (MFC) 128 which are incompatible safe concentrations these drugs plasma vivo Tigecycline showed lowest (0.25 2 mg/liter) MFC (1 8...
Abstract The contamination of consumer food and animal feed with toxigenic fungi has resulted in economic losses worldwide industries. Mycotoxins are highly biologically reactive secondary metabolites can inhibit protein synthesis cell multiplication. Considering the cytotoxicity mycotoxins, this experiment was performed to determine vitro influence ochratoxin A, deoxynivalenol zearalenone on lipid peroxidation lymphocytes broiler chickens at different concentrations. This study also...
Little detailed information is available on the association of Malassezia pachydermatis genotypes and extent skin damage that they cause. In present study, isolates M. pachydermatis, recovered from healthy dogs with dermatitis in Brazil, were characterized basis partial sequencing large subunit (LSU), first internal transcribed spacer (ITS-1) chitin synthase 2 gene (chs-2). The determination phospholipase production was also included investigations. severity lesions hyperpigmentation disease...
As drogas antifúngicas são classificadas em agentes químicos clássicos e atuais antibióticos. Os aqueles medicamentos que apresentam de maneira geral espectro ação reduzido contra fungos, atuando como fungistático modo indireto ao modificar as condições locais, por exemplo o iodo, os ácidos graxos derivados, ácido salicílico, tolnaftato tolciclato. representados pelos imidazóis triazóis, flucitosina alilaminas antibióticos poliênicos (anfotericina B, nistatina natamicina) a griseofulvina.

A neurological syndrome in dairy cattle associated with consumption of moldy beer residues is described. The disease occurred on 1 farm late June 2001, during winter. Six heifers and cow out 45 were affected a 3-week period. animals died spontaneously or euthanized approximately 2–14 days after the onset clinical signs. signs characterized by flaccid paralysis gait abnormalities. Clinical more pronounced exercise included stiff unsteady gait, knuckling at fetlocks hind limbs, frequent...
Three lipid-dependent Malassezia isolates (here named 114A, 114B and 114C) recovered from a dog with skin lesions were phenotypically genotypically characterized. All presented ovoid cells buds formed on narrow base. Most of the results physiological tests consistent those furfur. The phylogenetic analysis ITS-1 LSU nucleotide sequences was concordant in placing all three clinical close to M. However, data chs-2 sequence revealed that isolate 114A is distinct furfur closely affiliated...
Dermatophytosis caused by Microsporum canis is a heterogeneous disease with variable clinical manifestations. M. zoophilic dermatophyte and the most frequent fungi isolated from dogs, cats children in Brazil. The aim of this study was to investigate genetic variability isolates different animal species using two microsatellite markers, namely, McGT(13) McGT(17), correlate results epidemiological patient data included global set 102 strains, including 37 symptomatic cats, 35 asymptomatic 19...
1. The protective effect of a natural Brazilian calcium montmorillonite (CaMont) against aflatoxins was studied in broiler chickens. 2. A total 1056-d-old Cobb male broilers were housed experimental pens (22 chickens per pen) for 42 d. Three levels CaMont (0, 2.5 and 5 g/kg) two (0 3 mg/kg) assayed. Each treatment had 8 replicate 22 each. 3. Of all the tested experiment, ones treated with most adversely affected. at concentrations g/kg improved body weight d age by 13.3% 22.7%, increased...
Trichophyton verrucosum is the most commonly dermatophyte involved in cattle ringworm. This work reported a case of bovine dermatophytosis due to detected from clinical sample by SYBR-Green real-time PCR. The strategy was based on DNA extraction directly infected hair followed real‐time PCR and melting‐point analysis. A faster differential diagnosis observed when compared conventional mycological methodology for detection identification verrucosum.
