Lobação pulmonar e distribuição brônquica do ouriço-cacheiro (Sphiggurus villosus) / Lung lobation and bronchial distribution of the orange-spined hairy dwarf Porcupine (Sphiggurus villosus)

Background: The orange-spined hairy dwarf porcupine (Sphiggurus villosus) is a mammal found in Brazil, Venezuela, Guyanas and Bolivia. Its dorsum is yellowish brown and presents a great number of spines. There are no spines in the belly area, which is covered with softer fur. It can host ticks and louses, hemoparasites and endoparasites. This paper aimed to describe the lung lobation and the bronchial distribution of the orange-spined hairy dwarf porcupine. Materials, Methods & Results: The lungs of two orange-spined hairy dwarf porcupines, ran over by cars and with no damage in the viscerae, were used in the study. Animals were set with intramuscular and intravisceral injections of a 10% formaldehyde solution and further dissected. The right lung was bigger than the left one and presented cranial, middle, caudal and accessory lobes, and the cranial lobe was bilobated in cranial and caudal portions. The left lung presented cranial and caudal lobes, and the former was subdivided into cranial and caudal portions. The right main bronchus divided into three bronchi, one to the cranial, one to the middle and one to the caudal and accessory lobes. The right lobar bronchus gave origin to five segmental bronchi to the cranial portion and three segmental bronchi to the caudal portion; the middle lobar bronchus originated four segmental bronchi; the accessory lobe bronchus was originated from the right caudal lobe and divided into two segmental bronchi. The right lobar bronchus divided into eleven segmental bronchi. The main left bronchus bifurcated into one bronchus to the cranial lobe and one to the caudal lobe; the left cranial lobe bronchus divided into five to the cranial portion and two to the caudal portion; the left caudal lobe bronchus originated eleven segmental bronchi as well as the right one. Discussion: Markable interlobar fissures were noticed between lobes, similarly to the domestic carnivorous, to the crabeating raccoon (Procyon cancrivorus) and to wild rodents as agoutis (Dasyprocta azarae). There was a left lobe division, differently from the described in the crab-eating raccoon and horses, and similarly to the described in domestic carnivorous or in agoutis, capybaras (Hydrochoerus hydrochaeris) and pacas (Agouti paca). In all lobes, but the accessory lobe, lobar bronchi divided into several segmental bronchi, differently from the described in the right cranial and accessory lobes of the domestic carnivorous and of the crab-eating raccoon, and from the right middle lobe bronchus of the paca, which presented a bifurcated lobar bronchus. It also differed from the left cranial lobe of agoutis and pacas, which presented one or three segmental bronchi to this lobe, respectively. In the accessory lobe, there was a lobar bronchus bifurcating in segmental bronchi, as described in the domestic carnivorous and in the crab-eating raccoon. The bronchial distribution and lung lobation of the orange-spined hairy dwarf porcupine were different from the ones reported in domestic carnivorous and horses, wild rodents and from the crab-eating raccoon, with a markable division in the left and right cranial lobes, as in the domestic ruminants, from whom it differed due the absence of the tracheal bronchus.

LOBAÇÃO PULMONAR E DISTRIBUIÇÃO BRÔNQUICA DA JARITATACA (Conepatus semistriatus, Boddaert, 1785) COMUNICAÇÃO CURTA

Este estudo objetivou descrever a lobação pulmonar e a distribuição brônquica da jaritataca. Foram utilizados quatro espécimes provenientes de atropelamentos. Os animais exibiram pulmões em forma de semicone e a os lobos cranial, médio, caudal e acessório formaram o pulmão direito. O pulmão esquerdo exibiu lobos cranial e caudal, sem divisão do lobo cranial. O brônquio principal direito se trifurcou em um brônquio para o lobo cranial, um para o médio e um para os lobos caudal e acessório. O brônquio lobar cranial direito se dividiu em três brônquios segmentares; o brônquio lobar acessório e o lobar médio direito originam dois brônquios segmentares; o brônquio lobar caudal direito deu origem a seis brônquios segmentares. O brônquio principal esquerdo bifurcou-se em um brônquio para o lobo cranial e um para o lobo caudal. O brônquio lobar cranial esquerdo dividiu-se em seis brônquios segmentares, assim como o brônquio lobar caudal esquerdo. A distribuição brônquica e a lobação dos pulmões da jaritataca são diferentes das reportadas em carnívoros domésticos e roedores selvagens.

Análise microbiológica de caldos de cana comercializadas na ruas de Curitiba, PR / Microbiological analysis of sugar cane juice commercialized in the streets of Curitiba, PR

É importante analisar a qualidade microbiológica do caldo de cana e de outros produtos vendidos por ambulantes nas ruas das cidades, pois são preocupantes as condições higiênico-sanitárias nas quais eles são produzidos, podendo constituir foco de disseminação de DTAs (doenças transmitidas por alimentos). Este trabalho teve como objetivo analisar a qualidade microbiológica de caldos de cana comercializados nas ruas da cidade de Curitiba-PR. Verificou-se que das trinta amostras estudadas, vinte e nove apresentavam padrão microbiológico satisfatório. No entanto, foi observado entre os comerciantes diversos procedimentos inadequados de higiene, o que ressalta a necessidade de alertar a Vigilância Sanitária local quanto ao comércio ambulante, para que alie-se uma fiscalização ativa às ações de educação sanitária.(AU)

It is important to analyse the quality of the sugar cane juice and other products sold by ambulant sellers on the streets, being the higienic-sanitary conditions on wich they are produced a point of concern, as they can be the starting point of Food Born Diseases. This study was intended to analyse the microbiologic quality of the sugar cane juice sold on streets of Curitiba-PR. From the thirty samples studied, twenty-nine showed satisfactory microbiologic standards. Though, several non-adequate hygienic procedures were observed, wich shows the need of allerting the local sanitary authorities about the informal street comerce, so that an active vigilancy starts working along sanitary education actions.
