1. Adenovirus 36 infection and daycare starting age are associated with adiposity in children and adolescents
Abstract Objective This study aimed to investigate human adenovirus 36 (Adv36) as an associated factor for adiposity in children and adolescents aged 9-12 years. Methods This was a case-control study comparing overweight (cases) and eutrophic (controls) children and adolescents aged 9-12 years based on their body mass index in relation to human adenovirus

2. Serological response against bovine herpesvirus and bovine viral diarrhea virus induced by commercial vaccines in Holstein heifers
RESUMO: A vacinação é utilizada como estratégia para a prevenção e controle das doenças reprodutivas, causadas pelos vírus da diarreia viral bovina (BVDV) e herpesvírus bovino tipo 1 (BoHV-1), entretanto, as diversas composições de vacinas comerciais devem ser avaliadas quanto a sua eficiência protetiva mediada por anticorpos (Acs). O objetivo de

3. Infecção latente pelo herpesvírus bovino tipo 1 em búfalos (Bubalus bubalis) no Rio Grande do Sul
RESUMO Apesar dos bovinos serem considerados os hospedeiros naturais do BoHV-1, estudos sorológicos têm sugerido que búfalos podem ser suscetíveis ao BoHV-1 e a outros alfa-herpesvírus geneticamente relacionados. O objetivo deste estudo foi detectar a presença de DNA viral de BoHV-1 em 202 amostras de gânglios trigêmeos de búfalos, pela técnica de

4. Soroprevalence of bovine alphaherpesvirus type 1 (BoHV-1) and risk factors associated with dairy properties of the municipality of Senador Guiomard, Acre, Brazil
RESUMO O alfaherpesvírus bovino tipo 1 (BoHV-1) é o agente etiológico responsável por graves infecções que comprometem os tratos respiratório e genital dos bovinos acometidos. Com o objetivo de estimar a soroprevalência de BoHV-1 e identificar os fatores de risco associados em propriedades leiteiras do município de Senador Guiomard, Acre, foi realiz

5. Bovine alphaherpesvirus 1 and 5 in semen from bulls presenting genital lesions under field conditions in Brazil
RESUMO Os alfa-herpesvírus bovinos 1 e 5 (BoHV-1/5) são importantes patógenos de doença respiratória, reprodutiva e neurológica em bovinos. O objetivo deste estudo foi investigar a frequência de detecção de anticorpos neutralizantes contra BoHV-1/5 em amostra de soro e detectar DNA viral em sêmen de touros do rebanho bovino localizado nas fazendas

6. Antivenomic approach of different Crotalus durissus collilineatus venoms
Abstract Background: Our group has previously performed a proteomic study verifying that individual variations can occur among Crotalus durissus collilineatus venoms. These variations may lead to differences in venom toxicity and may result in lack of neutralization of some components by antivenom. In this way, this study aimed to evaluate the Brazilian ant

7. Alpha-type phospholipase A2 inhibitors from snake blood
Abstract It is of popular and scientific knowledge that toxins from snake venom (among them the PLA2 and myotoxins) are neutralized by various compounds, such as antibodies and proteins purified from animal blood. Venomous and nonvenomous snakes have PLA2 inhibitory proteins, called PLIs, in their blood serum. One hypothesis that could explain the presence o

8. Cloning, structural modelling and characterization of VesT2s, a wasp venom hyaluronidase (HAase) from Vespa tropica
Abstract Background: Wasp venom is a complex mixture containing proteins, enzymes and small molecules, including some of the most dangerous allergens. The greater banded wasp (Vespa tropica) is well-known for its lethal venom, whose one of the major components is a hyaluronidase (HAase). It is believed that the high protein proportion and activity of this e

10. Diagnosis of arboviruses using indirect sandwich IgG ELISA in horses from the Brazilian Amazon
Background The Amazon as a whole is the largest reservoir of arboviruses worldwide, while the Brazilian Amazon hosts the largest variety of arboviruses isolated to date. In this study, the results of an indirect sandwich IgG ELISA, standardized for 19 arbovirustypes circulating among horses in Brazilian Amazon, were compared to results of the hemagglutinat

11. Evaluation of different adjuvants formulations for bluetongue vaccine
This study investigated the adjuvant potential of W/O/W multiple emulsions and microemulsions, comparing them with traditional aluminum hydroxide and oil-in-water emulsion adjuvants against bluetongue vaccine (BTV). Local inflammatory reactions were assessed in rabbits by measuring the temperature of the animals and the skin thickness at the site of applicat

12. Mimotopes selected by biopanning with high-titer HIV-neutralizing antibodies in plasma from Chinese slow progressors
OBJECTIVE: One approach to identifying HIV-1 vaccine candidates is to dissect the natural antiviral immune response in treatment-naïve individuals infected for over ten years, considered slow progressor patients (SPs). It is suspected that SP plasma has strongly neutralizing antibodies (NAb) targeting specific HIV viral epitopes. METHODS: NAbs levels of 11
