Como proposição central, este artigo apresenta a seguinte problemática de pesquisa: como as tecnologias de informação e de comunicação podem auxiliar uma maior interação entre o espaço rural e o espaço urbano? Como objetivo geral, o artigo buscou compreender como as Tecnologias de Informação e de Comunicação podem ser utilizadas para a interação entre espaço urbano e rural. Especificamente, descreve a lacuna na definição das bases conceituais do que é espaço rural e urbano e observa o papel da comunicação, em específico das Tecnologias de Informação e de Comunicação, como mediador para uma compreensão destes espaços e das interferências mútuas que ocorrem. Como aporte metodológico utilizou a revisão bibliográfica e as teorias que conceituam campo e cidade, sobretudo nas discussões sobre conceitos intrínsecos aos fatores comunicacionais.
In Brazil, notification of toxoplasmosis outbreaks and epidemiological investigation is a mandatory activity of health surveillance. We investigated the risk factors for toxoplasmosis during outbreaks, notifications of outbreaks by the health secretary and reports in the literature. Other factors related to the municipalities were determined through the Institute of Geography and Statistics portal. We found that fruits and vegetables were the most described transmission routes in outbreaks, and oocysts were the most common parasitic form; in recent years; there has been an increase in outbreak notifications. We also found that municipalities with high municipal human development index have a higher number of toxoplasmosis infections during outbreaks. There is a need to raise awareness among the population and producers regarding good water management and quality practices and to facilitate the acquisition of complex data to improve preventive strategies.
There is an increase in tick-borne diseases in dogs in urban and rural areas in Brazil and some of these are of public health importance. Rhipicephalus sanguineus-transmitted hemoparasitoses are the main causes of mortality in dogs. The present study investigated the molecular occurrence of Ehrlichia canis, Babesia vogeli and Anaplasma platys in dogs with clinical sings and hematological abnormalities suggestive of tick-borne diseases. These dogs were seen at a Veterinary Hospital of a Public University between January 2014 and December 2016, and were evaluated through anamnesis, clinical examination and complementary exams. The polymerase chain reaction technique was used to detect the presence of hemoparasites DNA. From the 461 dogs that were tested for B. vogeli, 10.6% (49/461) were positive, the associated variable was age. Regarding the 730 animals screened for E. canis, 15.1% (110/730) were positive, and the infection was associated with hematocrit and number of platelets. Relative to the 86 samples evaluated for A. platys, 15.1% (13/86) were positive, and no variable presented statistical significance. From the animals positive for B. vogeli, no of these showed positivity by qPCR for Rangelia vitalii. It is concluded that the occurrence of hemoparasitosis in dogs from the Londrina region is common. Therefore, it is emphasized that molecular techniques should be used as an auxiliary tool for the differential diagnosis of the different etiological agents causing hemoparasitosis. Additionally, these molecular tools are essential for better investigation and preventive assertiveness because it allows to detect parasite DNA.
Abstract This study aimed to identify the intestinal parasites of road-killed wild felines in the North Central and North, Paraná state, southern Brazil. The animals were monitored by sampling previously established transects. The places where the felines were run over were mapped, the animals were identified, and the gastrointestinal tract was evaluated. The feces were submitted to coproparasitological techniques of spontaneous sedimentation, floating in hypersaturated NaCl solution and centrifugal floating in zinc sulfate. All the parasitic structures detected were photomicrographed. In the coproparasitological analyses were identified oocysts of Cystoisospora spp., eggs of Ancylostomatidae, and Capillaria spp.; eggs of Aelurostrongylus spp., Toxocara spp., Physaloptera spp., Taenia spp., and Spirometra spp.; Aelurostrongylus abstrusus larvae; and eggs and adults of Ancylostoma cati and Taenia spp. One of the cats was parasitized by a flea of Ctenocephalides felis felis. Based on these results, the animals analyzed in this study supplied important samples for the evaluation of parasitic diversity of North of Paraná and suggested that this region may have conditions that allow the maintenance of these parasites life cycles in the environment and among wildlife.
Abstract American cutaneous leishmaniasis (ACL) is a notifiable dermatozoonosis with relevant morbidity. The present study aimed to evaluate the epidemiological aspects of cases of ACL reported in Northern Paraná (2007–2016), as well as to georeference and analyse the influence of economic, social and environmental variables. Data from ACL notification forms were obtained and the patients' houses were georeferenced. Descriptive statistics, calculations of disease incidence and proportion of vegetation cover by municipality, spatial analysis, multiple linear regression and vulnerability analysis by census sector (CS) were performed. One thousand four hundred fifty‐one cases of ACL were reported in the 89 municipalities of four regional health (RH). The average incidence of cases per 10,000 inhabitants was as follows: 11.58, 8.79, 4.92 and 4.03 in 18thRH, 15thRH, 16thRH and 17thRH. Peaks of incident cases were observed in 2008, 2012 and 2015. There was a statistically significant difference between the HR when comparing the proportions of the variables gender, age, education level, area of residence, clinical form, diagnostic criteria, response to treatment and drug used in case of failure. It was observed that the lower the proportion of remaining Atlantic Forest, the greater the incidence of ACL in the municipality. With regard to clusters analysis, treatment abandonment clusters were observed in the 15thRH and mucous form clusters were observed in the 15thRH, 16thRH and 17thRH. The vulnerability analysis by CS allowed us to observe a statistically significant difference in all vulnerability indicators: economic and social in 15thRH and 17thRH; home infrastructure in 15thRH and 18thRH, urban infrastructure in 15thRH and 18thRH and compound vulnerability index in 15thRH and 18thRH. However, the most vulnerable areas did not always have the highest number of cases. The data presented demonstrate that preventive and health education measures must be mainly directed to areas of greater degradation of native forest; regardless of the vulnerability situation.
