1. ANTICORPOS POLICLONAIS PARA O IMUNODIAGNÓSTICO DE VÍRUS BOVINO
Resumo O objetivo do estudo foi produzir anticorpos policlonais para vírus bovino e testar a reatividade em imunoensaios como imunofluorescência, imunoperoxidase e slot blot. Como imunógeno utilizou-se cepas e/ou isolados dos herpesvírus bovino tipo 1, 2 e 5 (BoHV-1, BoHV-2 e BoHV-5), vírus da diarreia viral bovina (BVDV), vírus respiratório sincicial

2. Treatment of ligneous conjunctivitis with heterologous serum
RESUMO A conjuntivite lenhosa é uma forma rara de conjuntivite bilateral crônica e recorrente, na qual há formação de membranas espessas na conjuntiva tarsal e em outras mucosas. Relatamos o caso de uma paciente de 55 anos com conjuntivite lenhosa bilateral, que obteve sucesso no tratamento com soro heterólogo em concentração de 50%. Não houve recor

3. 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

4. Parenteral adjuvant potential of recombinant B subunit of Escherichia coli heat-labile enterotoxin
BACKGROUND The B subunit of Escherichia coli heat-labile enterotoxin (LTB) is a potent mucosal immune adjuvant. However, there is little information about LTB's potential as a parenteral adjuvant. OBJECTIVES We aimed at evaluating and better understanding rLTB's potential as a parenteral adjuvant using the fused R1 repeat of Mycoplasma hyopneumoniae P97 ad

5. Molecular detection of mixed infections with multiple dengue virus serotypes in suspected dengue samples in Tamaulipas, Mexico
This study aimed to detect dengue virus (DENV) serotypes in serum samples obtained in Matamoros Tamaulipas, Mexico, and to determine the concordance of conventional nested reverse transcriptase polymerase chain reaction (RT-PCR) and a serological test [enzyme-linked immunosorbent assay (ELISA NS1)]. Here, we detected mixed infections consisting of four serot

6. A clinical trial protocol to treat massive Africanized honeybee (Apis mellifera) attack with a new apilic antivenom
Abstract Background Envenomation caused by multiple stings from Africanized honeybees Apis mellifera constitutes a public health problem in the Americas. In 2015, the Brazilian Ministry of Health reported 13,597 accidents (incidence of seven cases per 100,000 inhabitants) with 39 deaths (lethality of 0.25%). The toxins present in the venom, which include m

7. Human FcRn can mediate the transport across intestinal mucosal barrier and prolong the half-life of rabbit IgG in vivo
FcRn (neonatal Fc receptor) plays an important role in IgG transportation, antigen presentation and signal transmission. In this study, the complement fixation test and flow cytometry test were performed to verify whether the heterologous antibody could be transmitted to the serum or leukocyte with FcγR (Fc gamma receptor) across the intestinal mucosa. The

8. Post-exposure treatment of Ebola virus using passive immunotherapy: proposal for a new strategy
Background Better treatments are urgently needed for the management of Ebola virus epidemics in Equatorial Africa. Methods We conducted a systematic review of the literature on the use of passive immunotherapy for the treatment or prevention of Ebola virus disease. We placed findings from this review into the context of passive immunotherapy currently used

9. Environmental influences on antibody-enhanced dengue disease outcomes
Because an enriched environment (EE) enhances T-cell activity and T-lymphocytes contribute to immunopathogenesis during heterologous dengue virus (DENV) infections, we hypothesised that an EE increases dengue severity. To compare single serotype (SS) and antibody-enhanced disease (AED) infections regimens, serial intraperitoneal were performed with DENV3 (ge

10. Experimental model of heterotopic ossification in Wistar rats
Heterotopic ossification (HO) is a metaplastic biological process in which there is newly formed bone in soft tissues adjacent to large joints, resulting in joint mobility deficit. In order to determine which treatment techniques are more appropriate for such condition, experimental models of induced heterotopic bone formation have been proposed using hetero

11. Assessment of immunity against avian colibacillosis induced by an aroA mutant containing increased serum survival gene in broilers
Colibacillosis is an important disease in the poultry industry which causes serious economic damages. As it is suggested that vaccination is one of the means to control colibacillosis, we tried to investigate the vaccine potential of a ΔaroA derivative of an O78:K80 avian pathogenic Escherichia coli containing increased serum survival gene. 490 chicks were

12. Use of heterologous antigens for the immunodiagnosis of abdominal angiostrongyliasis by an enzyme-linked immunosorbent assay
Angiostrongylus costaricensis has a broad geographic distribution spanning from North to South America and the infections of vertebrates with this nematode can result in abdominal complications. Human infections are diagnosed by histological or serological methods because the isolation of larvae from feces is not feasible, as most parasites become trapped in
