1. Identification of Leishmania species by high-resolution DNA dissociation in cases of American cutaneous leishmaniasis,
Abstract Background American cutaneous leishmaniasis is an infectious dermatosis caused by protozoa of the genus Leishmania, which comprises a broad spectrum of clinical manifestations depending on the parasite species involved in the infections and the immunogenetic response of the host. The use of techniques for amplification of the parasites DNA based on

2. Detection of enteric agents into a cats’ shelter with cases of chronic diarrhea in Southern Brazil
RESUMO: Uma pesquisa de agentes enteropatogênicos em gatos domésticos de um abrigo foi realizado como etapa da investigação das causas de diarreias crônicas intermitentes. Amostras fecais individuais de 39 gatos, com livre acesso ao ambiente externo, foram obtidas para pesquisa de helmintos através do exame parasitológico, investigação de parvovíru

3. Use of Mini-FLOTAC and Fill-FLOTAC for rapidly diagnosing parasitic infections in zoo mammals
Resumo Animais criados em ambiente restritos são altamente suscetíveis a infecção gastrointestinal por helmintos e protozoários, constituindo os zoológicos em ambientes com alta contaminação por parasitos. O sucesso da implementação de programas de controle contra estes parasitos em zoológicos depende do rápido diagnóstico das infecções por p

4. Skin manifestations of tick bites in humans
Abstract: Ticks are blood-sucking arthropods that attach to human skin through oral devices causing diverse initial cutaneous manifestations, and may also transmit serious infectious diseases. In certain situations, the Health Teams (and especially dermatologists) may face difficulties in identifying the lesions and associating them to the parasites. To assi

5. Socioenvironmental conditions and intestinal parasitic infections in Brazilian urban slums: a cross-sectional study
ABSTRACT Intestinal parasitic infections (IPIs) are neglected diseases with limited data regarding prevalence in Brazil and many other countries. In increasingly urban societies, investigating the profile and socioenvironmental determinants of IPIs in the general population of slum dwellers is necessary for establishing appropriate public policies catered to

6. Silver and Silver Chloride Nanoparticles and their Anti-Tick Activity: a Mini Review
This overview highlights the importance of characterization of biogenic nanoparticles of silver and silver chloride in order to understand the action on ticks or pathogens transmitted by them. These nanoparticles appear as important active principles in this area. They can act against ticks or against major pathogens transmitted by the bite of ticks such as

7. Biological rhythms and vector insects
The adjustment of all species, animals and plants, to the Earth’s cyclic environments is ensured by their temporal organisation. The relationships between parasites, vectors and hosts rely greatly upon the synchronisation of their biological rhythms, especially circadian rhythms. In this short note, parasitic infections by Protozoa and by microfilariae hav

8. Estudo do papel do ATP na ativação do sistema imune e na proteção durante a infecção por Plasmodium chabaudi. / Role of ATP in the immune response to blood-stage Plasmodium chabaudi malaria.
Estima-se que a malária seja responsável por um milhão de mortes anuais, atingindo principalmente crianças. O sistema imune participa tanto na proteção contra a infecção pelo plasmódio, como no desenvolvimento das síndromes associadas à malária (anemia, malária cerebral, acidose metabólica e choque sistêmico). Recentemente, tem sido mostrado q

9. Inquérito epidemiológico de infecções parasitárias intestinais em trabalhadores rurais canavieiros nas regiões de Campinas e Ribeirão Preto / Epidemiological survey of intestinal parasitic infections in rural sugarcane workers in the regions of Campinas and Ribeirão Preto
Intestinal parasitic diseases represent a serious public health problem worldwide, with prevalence rates varying in each region, and socioeconomic and environmental factors to corroborate maintaining or increasing the number of cases. Rural workers in sugar cane plantations, due to weather conditions and which are submitted during the rural work, and suffer

10. Diagnosis of Giardia infections by PCR-based methods in children of an endemic area
The present study was designed to estimate the prevalence of Giardia infection in preschool- and school-aged children living in an endemic area. Fecal samples from 573 children were processed by zinc sulfate centrifugal flotation, centrifugal sedimentation (using a commercial device for fecal concentration - TF-Test kit®) and polymerase chain reaction (PCR)

11. Metronidazole release using natural rubber latex as matrix
Natural Rubber Latex (NRL) can be used successfully in controlled release drug delivery due to their excellent matrix forming properties. Recently, NRL has shown to stimulate angiogenesis, cellular adhesion and the formation of extracellular matrix, promoting the replacement and regeneration of tissue. A dermatological delivery system comprising a topically

12. Parasitos gastrintestinais de avestruzes (Struthio camelus) de diferentes idades e sua ocorrência nas épocas seca e chuvosa em um criatório no Município de Itaboraí, Estado do Rio de Janeiro. / Gastrointestinal parasites of ostriches (Struthio camelus) of different ages and their occurrence in the dry and rainy seasons in a farm in Itaboraí City, State of Rio de Janeiro.
Ostriches are susceptible to many diseases and until recently, many of them are unknown and can affect these animals when it comes to commercially breeding. In Brazil, the commercial establishment has been initiated 20 years ago, but already there are reports about the diseases that can affect these birds. The objectives of this study were identify morpholog
