1. Que orientações o ACS pode fornecer nas visitas domiciliares para prevenção da histoplasmose?
Histoplasmose é uma infecção causada pelo fungo Histoplasma capsulatum. Embora na grande maioria das vezes seja assintomática ou auto-limitada, em alguns indivíduos pode desenvolver infecção pulmonar aguda (tipo uma pneumonia) ou infecção disseminada progressiva e severa (infecção generalizada), sobretudo em pacientes imunodeprimidos (ex: infec

2. Thermotolerance of Histoplasma capsulatum at 40 °C predominates among clinical isolates from different Latin American regions
ABSTRACT The yeast phase of 22 Histoplasma capsulatum clinical isolates from Mexico, Argentina, Colombia, and Guatemala and three reference strains, one from Panama and two from the United States of America (USA), were screened for thermosensitivity characteristics using different analyses. Growth curves at 0, 3, 6, 12, 24, and 30 h of incubation at 37 and 4

3. Mixed infection by Histoplasma capsulatum isolates with different mating types in Brazilian AIDS-patients
ABSTRACT Mixed infection by Histoplasma capsulatum isolates with different mating types, in AIDS-patients are described in this study. Morphological, mating type-specific PCR assay and multilocus sequencing type analysis of H. capsulatum isolates recovered from two Brazilian AIDS-patients were performed. Five H. capsulatum isolates were recovered at differen

4. Histoplasma panniculitis in a patient with systemic lupus erythematosus
Abstract: Histoplasmosis usually presents primarily as lung infection. Occasionally, mainly in immunocompromised hosts, it can spread and cause systemic manifestations. Skin lesions have been reported in 10 to 15 percent of cases of disseminated histoplasmosis, and panniculitis has been described as an unusual form of presentation in affected patients. We pr

5. Multiplex polymerase chain reaction as an improved method for screening Histoplasma capsulatum mating types
Histoplasmosis is a systemic mycosis infection caused by Histoplasma capsulatum, a heterothallic ascomycete. The sexual reproduction of this fungus is regulated by the mating type (MAT1) locus that contains MAT1-1 and MAT1-2 idiomorphs, which were identified by uniplex polymerase chain reaction (PCR). This study aimed to optimise single-step multiplex PCR fo

6. Clinical outcomes and risk factors for death from disseminated histoplasmosis in patients with AIDS who visited a high-complexity hospital in Campo Grande, MS, Brazil
Abstract INTRODUCTION: Disseminated histoplasmosis (DH) is a systemic mycosis caused by Histoplasma capsulatum (H. capsulatum) and is characterized by progressive and fatal evolution in immunocompromised patients. Moreover, it is considered an AIDS-defining disease. METHODS: We performed an observational, analytical, retrospective study to identify the cl

7. Epididymo-orchitis caused by Histoplasma capsulatumin a Colombian patient
Abstract Although histoplasmosis is generally a self-limited disease, disseminated infection can occur in patients lacking effective cell-mediated immunity, reaching virtually every organ, even the genitourinary tract in rare cases. We report a case of epididymo-orchitis in an immunocompetent 38-year-old bricklayer from the rural area of Villeta, Cundinamarc

8. Morphological changes in the digestive system of 322 necropsies of patients with acquired immune deficiency syndrome: comparison of findings pre- and post-HAART (Highly Active Antiretroviral Therapy)
ABSTRACT Involvement of the digestive system in AIDS pathologies or injuries is frequent. Aiming at comparing the frequency, the importance that these lesions have for death and the survival time in patients using or not using HAART, we studied 322 necropsies classified as follows: Group A - without antiretroviral drugs (185 cases); B - one or two antiretrov

9. Use of fluorescent oligonucleotide probes for differentiation between Paracoccidioides brasiliensis and Paracoccidioides lutzii in yeast and mycelial phase
BACKGROUND Fluorescence in situ hybridisation (FISH) associated with Tyramide Signal Amplification (TSA) using oligonucleotides labeled with non-radioactive fluorophores is a promising technique for detection and differentiation of fungal species in environmental or clinical samples, being suitable for microorganisms which are difficult or even impossible

10. Terpinen-4-ol, tyrosol, and β-lapachone as potential antifungals against dimorphic fungi
Abstract This study aimed to evaluate the in vitro antifungal activity of terpinen-4-ol, tyrosol, and β-lapachone against strains of Coccidioides posadasii in filamentous phase (n = 22) and Histoplasma capsulatum in both filamentous (n = 40) and yeast phases (n = 13), using the broth dilution methods as described by the Clinical and Laboratory Standards Ins

12. Antiretroviral drugs saquinavir and ritonavir reduce inhibitory concentration values of itraconazole against Histoplasma capsulatum strains in vitro
Abstract Recent studies have shown that some drugs that are not routinely used to treat fungal infections have antifungal activity, such as protease inhibitor antiretroviral drugs. This study investigated the in vitro susceptibility of Histoplasma capsulatum var. capsulatum to saquinavir and ritonavir, and its combination with the antifungal itraconazole. Th
