| The creation of a mollusc pathology network was in effect and made official during 1992. The subject of this document is to present this network, which has not yet achieved its definitive size. Why this network? The creation of this network responds to several institutional and scientific needs. Indeed, the setting up of control measures aimed at regulating mollusc exchanges notably via European Directive 91/67 and its transcription into French law has, as a corollary, caused the recognition of IFREMER as the agency charged with performing the analyses necessary for responding to the needs of this Directive, as far as marine invertebrates are concerned. Moreover, France being among the primary producers of shellfish in the world, the setting up of a... |

| ABSTRACT The aim of this report was to describe the magnetic resonance imaging (MRI) and pathological features of a canine mixed glioma. A 12-year-old boxer male dog was presented for necropsy along with data from an MRI evaluation conducted ante-mortem. The images were examined and showed a poorly demarcated prosencephalic lesion, hyperintense on T2W images, hypointense on T1W images and heterogeneously hyperintense on T2W FLAIR images. There was mild nonuniform contrast enhancement, apparent midline shift, moderate perilesional edema and marked distortion of the adjacent lateral ventricle. The brain was evaluated macroscopically, microscopically and immunohistochemically. Grossly, there was a poorly demarcated soft mass, with areas of hemorrhage, within... |

| ABSTRACT: This study described the epidemiological, clinical, pathological and bacteriological aspects of Mannheimia haemolytica pleuropneumonia in goats associated with shipping stress. Forty goats transported from the Northeast to the Southern region of Brazil died during shipment, or 2-3 days after unloading. Clinical signs included dyspnea, mucopurulent nasal discharge, and coughing. All goats were necropsied, and multiple tissues were collected for histopathological analysis and involved agent identifications. All lungs showed pulmonary consolidation, predominantly affecting the cranioventral lobes, in addition to the marked fibrinous pleuritis, pleural thickening, and pleural adhesions, that affected 90% of the goats. Histologically, there was... |

| Among mollusc pathogens, paramyxeans are an important group of protistan parasites belonging to the genera Marteilia and Marteilioides. Martelia refringens and M. sydneyi are of particular concern given their potential impact on mollusc aquaculture world-wide. Aber disease and QX disease are currently listed by the OIE, the World Organisation for Animal Health. After more than thirty years of existence in the scientific literature, these organisms still pose questions and research challenges to investigators. This paper reviews current knowledge of the group and key references. The review was focused on taxonomy, epidemiology, pathology and potential control methods for these organisms in order to enhance understanding of paramyxean infection issues in... |

| ABSTRACT Laboratory breeding of annual fish is often impaired when fish fail to inflate the swim bladder after hatching. These fish, which are known as belly-sliders, cannot swim in the water column, moving mainly on the bottom of water. Therefore, we wanted to understand the factors underlying failed inflation of swim bladder in the annual fish Austrolebias nigrofasciatus and determine the implications of this condition on the growth of juveniles. To identify how the initial filling of the gaseous vesicle is compromised, and to determine the implications of this condition on juvenile growth, we analysed the histology of the swim bladder of both normal swimming fish and belly-sliders during their initial growth phase (first month of life). In addition to... |

| A malignant dendritic melanoma of the oral cavity with metastases widely spread in a cow is described. The clinicopathological manifestations, developed during a two-year period, was characterized by the difficulty in mastication and swallowing, progressive weight loss, weakness and profuse sialorrhea. At the necropsy, an ulcerated black mass was found at the left jaw projecting into the oral cavity. The tumor reached the chin, inferior lip and tongue. Metastases were detected within the tongue, parotid gland, lymph nodes, trachea, thyroid, pleura, lungs, heart, peritoneum, omentum, and serosal membranes of the forestomach and abomasum, liver, and intima of some hepatic vessels, mammary gland, and muscles and fasciae of the left hind leg. No reference to... |

| En febrero de 2003 en la Laguna de Yahuarcocha, se registró la muerte masiva de peces, estimándose que morían aproximadamente 500 peces/m2 por causas no conocidas. Fenómeno que se mantuvo durante algunas semanas disminuyendo paulatinamente el número de muertes. El Instituto Nacional de Pesca realizó un monitoreo durante los días 19 y 20 de marzo, con la finalidad de determinar las posibles causas, para lo cual se analizaron los parámetros ambientales, biológicos, identificación de las especies presentes en la laguna y la histopatología de los órganos y tejidos de los peces afectados. Los parámetros físico-químicos en la columna de agua y sedimentos registrados se encontraron dentro de los rangos normales para cuerpos lóticos. Desde el punto de vista... |

| ABSTRACT: Protozoal diseases caused by species of Sarcocystiscan cause serious damage in sheep flocks, inducing decreased growth conversion rates and partial or complete loss of carcasses at the slaughterhouse. This article describes an outbreak of Sarcocystis giganteainfection in sheep slaughtered in a farm in Rio Grande do Sul State, Brazil. Between July and September 2013, three sheep showed multiple nodules in the esophagus that were microscopically characterized as encapsulated cysts filled with elongated, basophilic, nucleated structures morphologically consistent with S. giganteabradyzoites. Diagnosis was made based on the epidemiological, macroscopic, and microscopic findings. This is the first report of this infection in sheep in Rio Grande do... |

| We present a description of osteological alterations observed in the tucuxi, Sotalia fluviatilis (Gervais, 1853) from a sample of 43 specimens. Fractures were the most frequent alterations in the sample (16%), occurring in various regions of the skeleton such as the ribs, hyoid apparatus, transverse and neural processes of vertebrae and scapula. We observed three individuals with ankylosis between the cervical vertebrae and two individuals with morphological changes (cranio-caudally elongated hemal arch and flattened cranial margin of the scapula). The only observed pathology was a case of osteomyelitis in the left dentary, which caused the loss of teeth, deformation of the associated alveoli and the formation of a medial fistula (lingual) for drainage of... |

| Bone diseases and tooth alterations in 47 specimens of Otaria byronia (Blainville, 1820), from southern Brazilian coast, were analized. Tooth wear and the associated bone pathologies were determined, as well as their percentuals. The main infection was osteomyelitis associated with tooth alterations, such as fractures and attrition, both of them exposing the pulp chamber. Tooth attrition increases with age, favoring fractures and their complications, including osteomyelitis, causing a high frequency of them in specimens presenting more pronounced tooth wear. In one specimen tuberculosis was found in the maxilla, perhaps primarily pulmonary. The high frequency of enamel hypoplasia might reflect cyclic food deficit. Infections and tooth fractures might be... |

| Three species of oysters have been or are cultivated in Europe: Crassostrea angulata, C. gigas, and Ostrea edulis. If we follow the taxonomic critera of Grassé, the European oysters belong to the group of Mollusca, class of Lamellibranchia or Bivalves, order of Filibranchia, family Ostreidae with two genera: C. angulata (Lamarck), Portuguese, cupped oyster; C. gigas, (Thunberg), Japanese or Pacific, cupped oyster; Ostrea edulis (Linné), fiat European oyster. Some authors think that C. gigas and C. angulata belong to the same species. lndeed, Ranson stated that the characteristics of the larvae are the same, and Menzel obtained viable hybrids (F2) between these two oysters. AIso, Buroker et al. in studying the genetic variations of proteins and enzymes of... |

| Clinical hepatic coccidiosis in New Zealand white rabbits (n=24) of either sex (aged 1-2 month) with clinical signs, pathology an therapy is presented. The infected rabbits showed anorexia, reluctance to move and death within 3-4 days. Liver showed irregular whitish nodules scattered on its surface and in deeper parenchyma. Characteristic histopathologjcal changes in liver with different developmental stages of Eimeria stiedae in the epithelial cells of bile ducts have been recorded. Treatment of infected rabbits with 2.5% oltrazuril (Baycox) at 25 ppm in water for 2 days was highly effective. The oocysts is appeared in the faeces on day 6 after treatment. No mortality was seen in treated rabbits while all the infected untreated rabbits died with in a... |
