2. Detection and clearance of a mosquito densovirus contaminant from laboratory stocks of Zika virus
BACKGROUND The Zika virus (ZIKV) epidemics that affected South America in 2016 raised several research questions and prompted an increase in studies in the field. The transient and low viraemia observed in the course of ZIKV infection is a challenge for viral isolation from patient serum, which leads to many laboratories around the world sharing viral stra

3. Cat ownership is associated with increased asthma prevalence and dog ownership with decreased spirometry values
The association between pet ownership and the development of allergic and respiratory diseases has been the aim of several studies, however, the effects of exposure in adults remain uncertain. The aims of the present study were to investigate the prevalence of asthma and lung function status among dog and cat owners. This cross-sectional study was performed

4. A fatal case of tuberculous meningitis in a child with juvenile idiopathic arthritis: a diagnostic challenge
Abstract The prognosis of tuberculous meningitis, a rare form of extrapulmonary tuberculosis, depends on the stage of treatment initiation. We report a fatal case of tuberculous meningitis. The patient had received successive tumor necrosis factor (TNF) antagonists and abatacept to treat juvenile idiopathic arthritis, with negative results for polymerase cha

5. Effect of dietary supplementation with butyrate and probiotic on the survival of Pacific white shrimp after challenge with Vibrio alginolyticus
ABSTRACT This study evaluated the performance, immunology, and survival of the Pacific white shrimp Litopenaeus vannamei to experimental challenge to Vibrio alginolyticus based on the use of the probiotic Lactobacillus plantarum and the combined use of probiotic and butyrate. Four different diets resulted from the addition of additives: butyrate, probiotic,

6. Performance and immunological resistance of Litopenaeus vannamei fed a β-1,3/1,6-glucan-supplemented diet after per os challenge with the Infectious myonecrosis virus (IMNV)
This study determined the efficacy of a β-1,3/1,6-glucan source on the survival, growth, and immunological responses of Litopenaeus vannamei challenged with infectious myonecrosis virus (IMNV). The work was conducted in 20 tanks of 500 L with clear water with constant recirculation and aeration. Shrimp weighing 2.6±0.4 g were stocked at 100 animals/m2 and

7. Social and immunological differences among uninfected Brazilians exposed or unexposed to human immunodeficiency virus-infected partners
Understanding the social conditions and immunological characteristics that allow some human immunodeficiency virus (HIV)-exposed patients to remain uninfected represents an on-going challenge. In this study, the socio-demographic and sexual behaviour characteristics and immune activation profiles of uninfected individuals exposed to HIV-infected partners wer

8. Inhibitory effect of liposomal quercetin on acute hepatitis and hepatic fibrosis induced by concanavalin A
Immune response plays an important role in the development of hepatic fibrosis. In the present study, we investigated the effects of quercetin on hepatitis and hepatic fibrosis induced by immunological mechanism. In the acute hepatitis model, quercetin (2.5 mg/kg) was injected iv into mice 30 min after concanavalin A (Con A) challenge. Mice were sacrificed 4

9. Experimental models in vaccine research: malaria and leishmaniasis
Animal models have a long history of being useful tools, not only to test and select vaccines, but also to help understand the elaborate details of the immune response that follows infection. Different models have been extensively used to investigate putative immunological correlates of protection against parasitic diseases that are important to reach a succ

10. Usefulness of pharmacy dispensing records in the evaluation of adherence to antiretroviral therapy in Brazilian children and adolescents
INTRODUCTION: Adherence, which is crucial to the success of antiretroviral therapy (HAART), is currently a major challenge in the care of children and adolescents living with HIV/AIDS. OBJECTIVE: To evaluate the prevalence of nonadherence to HAART using complementary instruments in a cohort of children and adolescents with HIV/AIDS followed in a reference se

12. Epidemiologic profile of patients attended at HIV/AIDS ambulatory of the Specialized Assistance Service (SAE) on Conselheiro Lafaiete city, Minas Gerais state, in the years of 2001 and 2008 / Perfil epidemiológico dos pacientes atendidos no ambulatório de HIV/Aids do Serviço de Assistência Especializada (SAE) de Conselheiro Lafaiete, MG, nos anos de 2001 e 2008
INTRODUCTION: The HIV/Aids epidemic is complex and dynamic and it spreads like a regional sub-epidemic mosaic. The increasing number of cases in small Brazilian municipal districts is a challenge to SUS. Conselheiro Lafaiete has 116,512 inhabitants and it is an micro-region center in the state of Minas Gerais. It has a SAE which attends HIV/Aids patients fro
