In Brazil, the importance of leishmaniosis it is seen in its high incidence and huge distribution, as well as the possibility of became a lethal disease. It´s a zoonosis of canids, felines, rodents e marsupials, that is transmitted to men through vector bugs. Visceral leishmaniosis, the most serious and prevalent form, strongly became as an emergent and endemic disease, seeing in many Brazilian states, also bringing a lot of problems to public health. Because of this, it´s notable that the increase of urbanization in the last 20 years put in quest all the control strategies existent, the measures implanted until today were incapable to eliminate the transmission as to impede the occurrence of new epidemics. The prevention of dogs through imunoprophylaxis appear as an alternative, however to have a safe use it´s needed other studies, that can bring real results. The research below shows the increase of visceral leishmaniosis during the years, associated mainly to human cases, besides of dismember the tries used or that will be used with objective of dicrease the spread of leishmaniosis

A leishmaniose é uma doença que atinge milhões de pessoas no mundo e, de acordo com a FUNASA, está se espalhando por todas as regiões do Brasil. O tratamento desta zoonose é ineficaz, pois os fármacos utilizados apresentam muitos efeitos colaterais e colaboram com o aparecimento de parasitas e vetores resistentes. Portanto um maior conhecimento sobre a biologia molecular destes protozoários poderá facilitar o descobrimento de novas terapias e desenvolvimento de drogas antiparasitárias. O complexo telomérico é formado pela interação de DNA com proteínas, sendo que estas últimas podem também interagir entre si. A proteína RPA de eucariotos compreende um complexo trimérico subdividido em três subunidades. Este cumpre independentemente ou juntamente com outras proteínas diversas funções vitais para a célula, entre elas, auxiliar na manutenção dos telômeros e ajudar a recrutar a telomerase. Além disso, ela parece ser um dos principais componentes do complexo de proteínas que interagem com o terminal simples fita telomérico de protozoários tripanosomatídeos. Curiosamente, em Leishmania spp., as subunidades 2 e 3, ao contrário da subunidade 1 da RPA, não fazem parte do complexo telomérico. Portanto a LaRPA-1 pode apresentar comportamentos peculiares quando comparada a RPA dos outros eucariotos, e se tornar um importante alvo ao se estudar a biologia molecular do parasita. Este trabalho tem como objetivo clonar, expressar e purificar os três diferentes mutantes truncados da proteína LaRPA-1 para, futuramente, utilizar-se estas proteínas recombinantes como ligantes em ensaios de interação proteína:proteína, visando mapear possíveis sítios ou domínios na proteína LaRPA-1.O gene que codifica LaRPA-1 já encontrava-se clonado e sequenciado no laboratório de Telômeros da UNESP de Botucatu....(Resumo completo, clicar acesso eletrônico abaixo)

Tuberculosis and brucellosis are important diseases in national scenario, as they affect national cattle and can be transmitted to human, as they are zoonosis. The transmission risk increases mostly for those who have strict contact with animals, as is this case of slaughterhouse workers. This paper presents a bibliographic review of data referent to both diseases occurring in bovine slaughterhouse workers in Brazil, characterizing as occupational zoonosis diseases. We still have few data available of this subject, what raise difficulties to know the real incidence of both diseases in national cattle and in people who work in contact with animals, and most of the time are not instructed to the risk that they are exposed and how to prevent it. It’s important to know which is the situation of both diseases so that prevention and even eradication measures can be taken, as we know the Veterinary has an essential function in this matter, protecting animal health as much as protecting national public health

Proteins of animal origin are among the most consumed foods in the world, this scenario highlights the pig production, providing much of the daily protein intake worldwide. Brazil has significant numbers in the production and export of pork to stand among the first in the world marker. Several diseases such as brucellosis, can configure a threat to this sector. Brucellosis in pigs is an important disease and zoonosis once it is the cause of great economic losses by making the species vulnerable to sanitary barriers as well as putting at risk the health of attendants of farms, slaughterhouses employees and consumers. Pigs slaughtered in slaughterhouses approved by competent organs guarentee the safety of employees, in the flowchart of slaughter, and consumers, but illegal slaughterhouses pose risk to public health

La Encefalopatía Espongiforme Bovina (EEB) es una enfermedad degenerativa mortal y transmisible del sistema nervioso central del ganado, con largo período de incubación y clínicamente se caracteriza por sintomas nerviosos, la reacción exagerada a los estímulos externos y dificultad locomoción. La EEB es una enfermedad del grupo de las Encefalopatías Espongiformes Transmisibles (EET), y consiste en una enfermedad zoonótica transmitida por comer alimentos contaminados con una proteína llamada príon. Se discute el control de enfermedades, celebrada en la carne de vacuno refrigerada masacre a través de las Material Especificado de Riesgo (MER) que son el cerebro, cráneo, ojos, amígdalas, médula espinal, gânglio del trigémino, gânglios de la raiz dorsal y el íleon distal. Estos organismos pueden contener el agente de la EEB y transmitir la enfermedad. Los controles se basan en la ley brasileña y las normas internacionales que dictan la recogida y destrucción de estos materiales, sino también las normas para la comercialización de productos procedentes de rumiantes, así como la prohibición de alimentar rumiantes com productos de origen animal

As leishmanioses são enfermidades infecciosas que costumam afetar populações de países de clima tropical e subtropical, em sua maioria subdesenvolvidos, uma vez que seus principais vetores necessitam de condições ambientais e climáticas adequadas facilmente encontradas nessas regiões, para se proliferar. Há diferentes formas clínicas que se caracterizam por sua evolução crônica, sendo a forma visceral (LV) uma das mais graves. Neste caso, a disseminação é relativamente rápida uma vez que existe também a abundância de um dos seus principais reservatórios domésticos, o cão, que vive bem próximo ao homem, o qual é também acometido por esta zoonose. Dessa maneira é preciso que as populações, principalmente aquelas localizadas em áreas endêmicas, saibam identificar os pontos principais dessa doença como a transmissão, sinais clínicos e prevenção. Por esse motivo, essa revisão sistemática objetivou procurar saber qual o conhecimento de diferentes populações sobre as leishmanioses. Foram utilizados os seguintes descritores: (knowledge) AND (population) AND (leishmaniasis), através de um levantamento bibliográfico em três bases de dados, LILACS, SCIELO e PUBMED. Foi possível concluir, através da análise de sete artigos, que o conhecimento das leishmanioses ainda se encontra muito superficial dentro das populações e que a principal fonte de informação ainda é a informal, de pessoa a pessoa

Considering the importance of zoonotic infections by Leishmania spp. and Toxoplasma gondii in Araçatuba region, São Paulo, this study determined the degree of knowledge of residents of Araçatuba about these two diseases. Questionnaires about these diseases were applied to 123 people. Regarding schooling, all the respondents were literate, and 69.9% (86/123) did not attend higher education and 30.8% (37/123) completed an undergraduate degree. Of these, 91.9% (34/37) knew the meaning of the term zoonosis, with significant difference compared to those who were not trained. This word was unknown by 57% (29/123) of total respondents. Most non-graduates, 59.3% (51/86) did not know what is toxoplasmosis and among graduates, 35.1% (13/37) ignored the subject.There were significant difference between these groups. Regarding the prevention of Leishmania infection, a greater proportion of the residents advocated environmental cleanup, the collar repellent and use of citronella. In relation to toxoplasmosis, 54.5% did not know the ways of transmission of this disease and among those with graduate degree, 13 ignoring any transmission medium. When it comes to prevention of this disease, 55.3% (68/123) did not know any prophylactic. In the group of higher education, 14 did not know how to prevent toxoplasmosis. The results of this study show that the majority of respondents are not aware about the mode of transmission of these diseases, especially in relation to toxoplasmosis.

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.
