Helmintoses zoonóticas transmitidas pelo consumo inadequado de peixes

Among the major food-borne parasitic zoonoses, the helminthiasis transmitted by consumption of fish have been highlighted because they involve a large number of individuals in many regions of the world in recent years. In the past, these parasitosis were restricted to underdeveloped nations or with peculiar eating habits; however the process of globalization of food production, the increased international travel and consumption of fish for their nutritional benefits caused the expansion into new areas, which had never before been recorded, making it a serious public health problem in some countries. This review discuss the main helminths transmitted by eating raw or undercooked fish, in order to alert the public, the scientific community and health authorities about their risks to human health, as well as stimulate the realization of new researches that contributes to a greater knowledge of the epidemiological situation in the country of these parasites and the development of strategies for prevention and control of them.

Microbiota fúngica de passeriformes de cativeiros da Região Noroeste do Estado de São Paulo

Birds are hosts for a rich fungal microbiota which can act as potent pathogens for humans and other species of animals, causing thereby serious public health problems. The objective of this study was to evaluate the participation of birds kept in containers in the epidemiology of infectious diseases such as cryptococcosis and aspergillosis, thus verifying the maintenance and spread of pathogens in the environment. 36 samples of excretas of passeriformes were collected and were cultivated in Sabouraud Dextrose Agar 4% at room temperature and 37°C. The isolated fungal colonies were classified according to their morphological and staining characteristics. Subsequently, those in yeast form were peaked in Niger Agar, incubated at 30°C. In one sample showed growth of more than one type of colony and there was verified the presence of 25.0% of Penicillium spp., 19.4% of Trichosporon spp., 13.9% of C. gattii, 11.1% of C. neoformans, 11.1% of Candida spp., 8.3% of Rhizomucor spp., 8.3% of Aspergillus spp., 2.8% of Nigrospora spp. and 2,8% of Geotrichum spp. It can be conluded by the expost that birds shed continuously pathogenic microorganisms in their feces acting in definitive form in the infectious diseases ecoepidemiology.

Programa de conscientização de idosos sobre posse responsável de animais de estimação em bairro periférico do município de Araçatuba, SP

Currently, responsible ownership of pets has been widely discussed. In the past, they were brought to our society and it is our duty nowadays to establish this relationship between man and animal. This study aimed at evaluating the level of knowledge of elderly dog owners about responsible ownership with emphasis on control of canine visceral leishmaniasis and at the same time make them aware of the precautions to be taken. An individual questionnaire on the subject was applied to 68 elderly people. They all belong to Nossa Senhora Aparecida Village, located on the suburb of Araçatuba-SP. Along with the interview, veterinary students advised them on the control of canine visceral leishmaniasis, the importance of sterilization in cats and dogs and the responsible ownership, with distribution of informative leaflets. Fecal samples from dogs were collected by the owners and they were sent to the Laboratory of Parasitology and Parasitic Diseases at Odontology Faculty at Araçatuba UNESP to be processed through the Willis-Mollay technique. Anthelmintic were acquired in the project and donated for the treatment of animals tested positive. 56.25% (63/112) out of the total number of dogs examined were females, aged between one and ten years. Only 32.14% (36/112) had access to the streets, 90.18% (101/112) were not castrated and 58% (65/112) were mixed breed (SRD). Among the owners, 88.24% (60/68) did not know what zoonosis is and 14.71% (10/68) were not aware what leishmaniasis is. Regarding the researched animals, 62.50% (70/112) had ectoparasites (fleas and ticks). It was also observed that 67.86% (76/112) of dogs had been dewormed, but in 59.82% (36/112) of cases, the intervals between these processes were irregular. For females, 85.71% (54/63) had no prevention heat and it was noted that 19.51% (8 / 41) had already given birth, had dystocia. With these data we can confirm the lack of information by these elderly and the need to establish community awareness and continued programs.

Contato com gatos: um fator de risco para a toxoplasmose congênita?

Toxoplasmosis is an important zoonosis and one of the most common parasitic infections throughout the world, which may cause among other problems several fetal pathologic alterations. Congenital toxoplasmosis is a result of transplacental transmission of Toxoplasma gondii due to a prime infection of the mother during pregnancy. Several studies have determined that the main risk factor for infection in pregnant women is the consumption of uncooked meat, which contributed from 30 to 63% of cases; other 6% to 17% of infections were related to contaminated soil. The relationship between pregnant women and their cats constitutes nothing more than a healthy experience when main transmission mechanisms and risk factors related to the disease are known.

Determinação do teor de glicose em bagaço de cana-de-açúcar hidrolizado pelo processo de conversão enzimática

The production of ethanol and sugar from sugarcane juice generate as byproduct, the bagasse. Currently, the bagasse, an industrial lignocellulosic biomass, can be used for production of second-generation ethanol, since when it is submitted to hydrolytic processes generates fermentable sugars. The objective of this study was to produce fungal enzymes capable of hydrolyzing this lignocellulosic biomass to generate glucose. For this, we used the mushroom species Lentinula edodes, Pleurotus ostreatus, Pleurotus eryngii, and Pycnoporus sanguineus as potential sources of laccase, manganese peroxidase and lignin peroxidase enzymes, capable of hydrolyzing the crushed sugarcane. The hydrolysis process was performed with the highest enzymatic activities observed from laccase in L. edodes (39.23 U-mL after 25 day incubation), P. ostreatus (2.5 U U-mL after 27 day incubation), P. sanguineus (80 U-mL after 27 days of incubation) and P. eryngii (16.45 U-mL 15 days incubation). MnP and LiP showed no significant results. The enzymatic hydrolysis of sugarcane bagasse in natura (32,17% hemicellulose, cellulose 52,45% and 10,62% lignin) and bagasse hydrolyzate with 7,0% H2SO4 (0,20% hemicellulose, 68,82% to 25,33% cellulose and lignin) were evaluated for each enzymatic obtained. Compared to others, the enzymes produced by P. sanguineus incubated in sugarcane bagasse showed better efficiency resulting in glucose with an average content of 0,14 g-L. Although the levels of glucose determined in this work were low in relation to the literature, it can be stated that the laccase, manganese peroxidase and lignin peroxidase enzymes demonstrated good hydrolytic potential, especially those produced by the fungus P. sanguineus.
