ABSTRACT

Dog bites are a known public health problem involving physical, mental and emotional traumas. From a forensic point of view, it has been stated that their morphological characters, and the intercanine and interincisive measurements, could allow a taxonomic and specific identification of the implicated animal. The aim of this study was to differentiate and identify the biological profile of a potential aggressor dog by analysing eight morphometric bite patterns belonging to three different dog breeds. The data obtained were analyzed following three categories: a) breeds; b) sexes among breeds; and c) sex within breed. Significant differences were detected among the variables (p≤ 0.05), but only the maximum maxillary intercanines width (MaxCW) allowed a breed differentiation. The other variables allowed a differentiation between two breeds or one breed over the others. The principal components analysis (PCA) allowed visualizing the degree of dispersion and relationship among the scores. It showed three well-defined and separated breed groups, and different degrees of dispersion within and among breeds. The most important variable for such a differentiation was MaxCW. When considering sex among breeds for males, it showed a statistically significant difference, but only the diastema located between the third left mandibular, incisive and the left mandibular canine (C-I-ManL) allowed breed differentiation. For females, only MaxCW allowed a differentiation among breeds. The multivariate analysis permitted with a 95 % confidence interval, a breed and sex differentiation. Besides, the PCA models allowed classifying, identifying, separating and graphically showing the relationship among the variables. This made it possible to differentiate between breeds and sexes. Due to the large range of dog breeds around the world, this multivariate analysis could also help determining the dog's weight and size, narrowing down towards an approximate number of offending dogs, focussing on a certain kind of dog breed, and pinpointing any suspect dog.


Las mordeduras de perros son un conocido problema de salud pública que involucra traumas físicos, mentales y emocionales. En la faz forense, se ha establecido que características morfológicas, así como las medidas intercanina e interincisiva, permitirían una identificación taxonómica y especifica del animal involucrado. El objetivo fue diferenciar e identificar el perfil biológico de un potencial perro agresor analizando ocho patrones morfológicos de mordeduras pertenecientes a tres diferentes razas caninas. Los datos fueron analizados considerando tres categorías: a) razas; b) sexo entre razas; y c) sexo en cada raza. Se observaron diferencias entre las variables (p≤0,05), pero sólo la distancia máxima entre caninos maxilares (MaxCW), permitió una diferenciación entre razas. Las otras variables permitieron una diferenciación entre dos razas o de una raza sobre las otras. El análisis de componentes principales (PCA) permitió visualizar el grado de dispersión y la relación entre las puntuaciones (dentro y entre razas). Se observaron tres grupos (razas) bien definidos y separados con diferentes grados de dispersión dentro y entre razas. La variable más importante para tal diferenciación fue la MaxCW. Al considerar sexo (machos) entre razas, se encontró diferencia estadísticamente significativa, pero sólo la medida del diastema localizado entre el tercer incisivo y canino izquierdo mandibulares (C-I-ManL) permitió la diferenciación entre razas. Para hembras, sólo la MaxCW permitió una diferenciación entre razas. El análisis multivariante permitió, con un intervalo de confianza del 95 %, diferenciar raza y sexo. El modelo PCA permitió además clasificar, identificar, separar y mostrar gráficamente la relación entre las variables. Esto posibilitó diferenciar entre razas y sexos. Debido a la gran variedad de razas de perros en el mundo, este análisis multivariado permitiría estimar peso y tamaño del animal, indicando un número aproximado de perros atacantes, centrándose en ciertos tipos de raza, y localizar a cualquier cánido sospechoso.

ABSTRACT

Las lesiones ocasionadas por mordeduras de animales de compañía constituyen un problema de importancia para la salud, por un lado se relaciona con los traumas directos y los derivados posteriormente tanto físicos como psicológicos, así como con aspectos relacionados con la transmisión potencial de una enfermedad mortal como es la rabia. Actualmente la rabia no se encuentra erradicada; aún se registran casos en animales de compañía de países limítrofes e incluso en provincias del norte de nuestro país. Asimismo en la Ciudad de Buenos Aires (CABA) se mantiene el ciclo aéreo de la rabia a través de los murciélagos. Éstos, al padecer la enfermedad, y por la afectación del sistema nervioso central, presentan: incoordinación, problemas de su sistema de radar, parálisis y muerte. Los perros y gatos domésticos, así como las personas, pueden tomar contacto con estos animales enfermos o muertos y contagiarse de rabia. Se analizan las denuncias efectuadas en la Ciudad de Buenos Aires durante 2017, así como los datos de los animales agresores

ABSTRACT

Over the last few centuries, the expansion of urbanization brought bats closer to urbanized areas, increasing the risk of accidents by bat bites. The morphology of bat bites can be varied, usually having an elliptical shape, about 0.5 cm along its greatest length, and the characteristic corkscrew bite pattern. The authors present the case of a patient who was repeatedly bitten by vampire bats for two months. A polymerase chain reaction was performed in the cutaneous nerves at the base of the hair follicles which showed negativity towards the rabies virus. The authors highlight the public health importance of this case, and discuss the morphological characteristics of these hematophagous bat bites.

ABSTRACT

INTRODUÇÃO: No presente trabalho objetivamos descrever o processo de colonização da Bacia do Alto Paraná, Sudeste do Brasil, por arraias, demonstrando sua atual situação e provável tendência, os impactos gerados e discutindo algumas ações de manejo e medidas mitigadoras. MÉTODOS: Foram realizadas entrevistas com ribeirinhos e profissionais de saúde para o levantamento de informações sobre a ocorrência de arraias e acidentes associados a estes animais, além de coletas e observações subaquáticas de potamotrigonídeos, entre 2004 e 2009, em localidades situadas nos Estados de São Paulo, Paraná e Mato Grosso do Sul, no Sudeste, Sul e parte do Centro-Oeste do Brasil. RESULTADOS: Três espécies de arraias foram identificadas na área de estudo, demonstrando utilizar os caminhos abertos pela Hidrovia Tietê-Paraná para se dispersarem. Dezesseis vítimas de acidentes envolvendo esses animais foram encontradas, notadamente banhistas e pescadores, chamando a atenção pelo fato dos casos não serem notificados e apresentarem elevada morbidade, com marcante incapacidade temporária para o trabalho. CONCLUSÕES: Este é o primeiro relato de invasão biológica envolvendo espécies de elasmobrânquios conhecido na literatura e, pelas arraias estarem colonizando áreas densamente povoadas e ampliando sua área de distribuição a cada ano, é de se esperar que sua interação negativa com humanos se intensifique, provocando alterações importantes no perfil epidemiológico dos acidentes por animais peçonhentos ocorridos no sudeste brasileiro.


INTRODUCTION: In this paper, our aim was to describe the process of colonization of the upper Paraná basin, southeastern Brazil, by stingrays, showing the current situation, likely trend and impact caused and discussing some management actions and mitigation measures. METHODS: Interviews were held with riverbank people and health professionals, to gather information on occurrences of stingrays and accidents associated with these animals, along with underwater observations and collection of specimens, between 2004 and 2009 in localities in the States of São Paulo, Paraná and Mato Grosso do Sul, in the southeastern, southern and part of the central-western regions of Brazil. RESULTS: Three species of stingrays were identified in the study area, thus demonstrating that they were using the paths opened by the Tietê-Paraná Waterway to disperse. Sixteen victims of accidents involving these animals were found, mainly bathers and fishermen. Attention was drawn to the fact that these cases had not been reported, yet they presented high morbidity with notable temporary incapacity for work. CONCLUSIONS: This is the first report on biological invasion involving species of elasmobranchs in the literature and, because stingrays are colonizing densely populated areas and are expanding their range of distribution each year, it can be expected that their negative interactions with humans will intensify, with important changes in the epidemiological profile of accidents due to venomous animals occurring in southeastern Brazil.

ABSTRACT

La convivencia del hombre y el perro ha resultado en beneficios mutuos durante miles de años, si bien en el último tiempo han surgido una serie de inconvenientes donde las lesiones por mordeduras ocupan un lugar destacado. El objetivo del presente trabajo fue describir las características epidemiológicas de las lesiones por mordedura de perro ocurridas a lo largo de un año en Tierra del Fuego. Se realizó un estudio observacional descriptivo, transversal, de los pacientes que ingresaron con lesiones por mordedura de perro al Servicio de Guardia Clínica y Pediátrica de los Hospitales y Centros de Salud desde el 1/3/05 hasta el 1/3/06. Se confeccionaron 382 planillas. El 49.5% fueron niños resultando más afectado el grupo de 5-9 años (44.4%; IC95% 37.2-51.8). En adultos correspondió al grupo de 15-24 años (29.5%; IC95% 23.2-36.5). Se registraron más lesiones en varones (57.6%) que en mujeres (42.4%) (x² = 8.6, p= 0.003). En los meses primavera y verano se registró el 56.5% de las lesiones, en la vía pública el 72.8% de ellas. Los perros de tamaño grande causaron el 49.7% (IC95% 44.6-54.9) de las lesiones. El 89.8% de los ataques fueron causados por perros ajenos. El 55.8% (IC95% 50.6-60.8) se registró en miembros inferiores y el 11% (IC95% 8.1-14.7) en cabeza y cuello. Los datos obtenidos demuestran que en Tierra del Fuego las lesiones por mordedura de perro afectan en forma permanente la salud e impactan en la calidad de vida de la población.


The coexistence between man and dog has resulted in mutual benefits during thousands of years, nevertheless some problems have recently arisen where bite injuries have an important role. The aim of this work was to describe the epidemiological characteristics of dog bite lesions which occurred during a year in Tierra del Fuego. A descriptive observational, transversal study of patients who were admitted with dog bite injuries to clinic and pediatric emergency services of hospitals and health centers was carried out between 3/1/05 and 3/1/06. A total of 382 records were made. The children group represents 49.5%. The group between 5 and 9 year-old was the most affected (44.4%; IC95% 37.2-51.8). In the adult group, that between 15 and 24 year-old was the most affected (29.5%; IC95% 23.2- 36.5). More lesions were registered in men (57.6%) than in women (42.4%) (x² = 8.6, p= 0.003). During spring and summer months, 56.5% of the lesions were registered. A 72.8% of the incidents occurred on the public highway. Dogs of big size were responsible of 49.7% (IC95% 44.6-54.9) of the injuries. The 89.8% of the incidents were caused by another person´s dog. Of the lesions, 55.8% (IC95% 50.6-60.8) were registered in lower extremities and 11% (IC95% 8.1-14.7) in head and neck. These data show that dog bite lesions affect the health and impact in the quality of life of the population of Tierra del Fuego, Argentina.

ABSTRACT

The ectoparasitic bee mite, Varroa destructor, is highly adapted to its natural and adopted honey bee hosts, Apis cerana and Apis mellifera. Adult females perforate the integument of bee pupae in such a way that they and their progeny can feed. We examined the wounds that founder females made, and usually found one, and rarely up to three, integumental wounds on pupae of A. mellifera multiply infested by V. destructor. The punctures were mainly on the 2nd abdominal sternite of the host. These perforations are used repeatedly as feeding sites by these hemolymph-sucking mites and by their progeny. The diameter of the wounds increased during pupal development. In brood cells containing 4-5 invading female mites and their progeny, healing of the wound is delayed, normally occurring just before the imaginal moult of the bee pupa. These wounds are subject to microbial infections, and they are relevant to the evolution of behavioral traits in these parasitic mites and their relations to host bees.
