The group is responsible for the isolation and characterization of more than 15,000 strains of at least 200 different types of arboviruses. 34 of which are pathogenic to humans, of which four have been associated with epidemics in the Brazilian Amazon, the dengue virus (DEN-1, DEN-2, DEN-3 and DEN-4 serotypes), yellow fever, Mayaro and Oropouche. Other arboviruses pathogenic to humans have been sporadically isolated from humans, but many are often isolated from hematophagous arthropods and wild vertebrates. Some of these are important disease agents in humans, mainly responsible for encephalitis or meningoencephalitis. Possible new arboviruses have been isolated and their characterization studies are ongoing. We have also developed new diagnostic methods for arboviruses with greater sensitivity and specificity and faster.

The Laboratory of Leishmaniasis Transmitters was created in 1981 by Professor Leonidas de M. Deane for understanding the need to have professionals in the Oswaldo Cruz Institute who sought answers to the gaps in the knowledge of leishmaniasis, in addition to creating a Laboratory of Reference for vector studies. In 1992, this group of studies on leishmaniasis was officially recognized as an Accredited Laboratory of the Oswaldo Cruz Institute, Laboratory of Leishmaniasis Transmitters – LTL (Portuguese acronym), with Elizabeth Ferreira Rangel as Chief Researcher. Since then, in addition to several research projects in leishmaniasis, the group has been dedicated to the training of human resources, guiding students at different levels ranging from Scientific Initiation to PhD, teaching classes and / or coordinating courses in Post- Including outside the Oswaldo Cruz Institute. In 2004, the LTL was formally recognized as a National Reference Laboratory for Entomological Surveillance in Leishmaniasis, becoming part of the FIOCRUZ Leishmaniosis Reference Network, where it has been carrying out diagnostic / identification of vectors, training of Health Secretaries and participating in actions of entomological surveillance in areas of transmission of leishmaniasis, providing technical consultancies for State and Municipal Health Secretariats, Health Surveillance Department/ Ministry of Health. Recently, the Leader of the group was appointed as a member of the Committee of Specialists in Control of Leishmaniasis, the World Health Organization and is an Advisor to the Committee for the Control of Leishmaniasis, at the Pan American Health Organization.

It has been possible to know the distribution of the different species of anopheline mosquitoes in several endemic areas of the Amazon, its potential as a vector of malaria, its biology and habits and this has offered subsidies to the control sector of this endemic. In addition, the resistance of the main vector species to insecticides has been evaluated as a basis for the control of vectors of malaria carried out by government agencies. The determination of the food source (s) of the mosquitoes in order to determine the degree of antrophilia of the species and its condition as a vector of this protozoosis also subsidizes the control of the endemic. We have evaluated the efficacy of impregnated nets using the integrity, bioassay and colorimetric tests. Still, using molecular tools it has been possible to determine the species of the albitarsis complex and to correlate them with the transmission in different Brazilian endemic areas.

The Laboratory of Immunogenetics has been developing epidemiological studies associated with genetic markers and their biological relation in the pathogenesis of infectious and parasitic diseases. In this sense, the group has been directed to the study of the bacterium Helicobacter pylori and its markers of virulence, and currently, also the serological and molecular diagnosis of Treponema pallidum in congenital infections. The biological and evolutionary significance of gene-environment interactions is relevant to analyze and understand the genetic composition of current human populations, as well as to determine the function and application of several molecular markers in the diagnosis and prognosis of various types of diseases, such as gastric cancer. The glycoconjugates of blood groups ABH and Lewis, among others, have been characterized as to their distribution in several gastric pathologies, demonstrating their potential prognostic marker. The study of the ABH blood group in different species was also started.
The Biomolecular Technology Laboratory was conceived with the aim of offering, in a pioneering way in the northern region of Brazil, studies and the provision of services directed to animal health and conservation. The group also works in the area of genetics and molecular biology of microorganisms to study the microbiological diversity of the Amazon, and from the same exploration and molecular engineering of new compounds with potential application in the pharmaceutical, nutraceutical, cosmetic and biofuel industries.

The studies developed and under development have made possible the knowledge about the distribution of amebiasis and toxoplasmosis in Belém, as well as the implantation and / or implementation of the laboratory diagnosis, including immunological methods, of these two Protozoan infections as well as giardiasis, cryptosporiosis, toxocariasis and malaria. As for toxoplasmosis, the laboratory diagnosis system was implemented for the different risk groups and a diagnostic network involving the municipal and state spheres for the pregnant and newborn population. In the case of toxocariasis, the helminth culture system was already implanted for antigen production and serological diagnosis in Belém. For amebiasis, a specific diagnostic method was established for the detection of Entamoeba histolytica antigen. Studies on malaria in the Amazon region have resulted in the knowledge of the degree of Plasmodium falciparum resistance to the antimalarial drugs, the genes involved in the resistance, the polymorphism of this protozoan, and the distribution of the Plasmodium vivax variants in our region. New methods to detect the resistance of this parasite to antimalarials are being implemented with the objective of improving the quality of the results and standardize methodology to make them comparable within Brazil and with those produced by the Amazonian countries. Also, rapid tests for the diagnosis of malaria (TDR) have been developed for sensitivity and specificity, as well as the consequence of the deletion of HRP2 and HRP3 genes in the performance of these tests.

The Laboratory of Virology, of the Biological Sciences Institute (ICB) of the Federal University of Pará (UFPA), nowadays coordinated by Professor Ricardo Ishak, was initiated by Dr. Francisco de Paula Pinheiro (Evandro Chagas Institute), still in 1970, as a by-product of his teaching collaboration with the ICB. However, the limitation of teaching activity prevented for some years, that hiring was made for an increase in the research and extension activities of this laboratory. Between 1997 and 2002, extension activity was prioritized when the Virology Laboratory became part of the Ministry of Health's National STD / AIDS Coordination Networks (T-Lymphocyte Determination, CD4 + and Plasma Viral Load Quantification). The association and commitment of the Laboratory of Virology with undergraduate and graduate studies has already prepared human resources that are now engaged in UFPA, HEMOPA, IEC and private laboratories in the city of Belém, as well as trained personnel that today teach, research and take graduation courses in places such as UNIFESP, UFRJ and in a laboratory unit of the Brazilian Army. The research projects of the Laboratory of Virology aim to elucidate aspects of the classic descriptive epidemiology of viral and bacterial agents that use the sexual way as the main form of dissemination in conjunction with the genetic characteristics of the host. In the last five years, the Virology laboratory received financial support from CNPq, PN-DST / AIDS / MS, the Department of Science and Technology of the State of Pará (SECTAM), the Foundation for Support and Research Development, FADESP, PROF (CAPES) of the NIH (USA) and the Japan Health Science Foundation (Japan).
