| ABSTRACT: The Guiana dolphin (Sotalia guianensis) is a small odontocete distributed from Santa Catarina state, Brazil, to Honduras. Although it is currently considered “near threatened” by the International Union for Conservation of Nature, considerable knowledge on health and disease aspects of this species has been gained over the last decade. The main threats for the species are represented by multiple anthropic factors. Guiana dolphins feed on a variety of taxa, primarily teleosts, crustaceans, and cephalopods. Herein, we reported a case of severe laryngeal displacement and esophageal impaction with ulceration associated with a deglutted adult leatherjacket (Oligoplites sp.). This fish species is not a common prey item of Guiana dolphins’ diet. Severe... |

| ABSTRACT: This study described the pathological and microbiological aspects of a fatal systemic Mortierella wolfii infection in a neonatal calf in southern Brazil. The calf was born clinically normal, but on the third day of life it presented apathy, unilateral hypopyon, and neurological signs, and in the next day it was euthanized. At necropsy, multiple soft, and white-yellow nodules were observed in the liver, spleen, kidneys, mesenteric lymph nodes, heart, and lungs. In the brain, reddish, and friable areas were found. In the eye, there were anterior and posterior synechiae, diffuse thickening of choroid, and anterior chamber filled by whitish and friable material. Microscopically, areas of necrosis, pyogranulomatous inflammation, vasculitis,... |

| A 33 month-old male flying squirrel kept in a zoo developed progressive dyspnea and died. Macroscopically, the liver and lung were enlarged with numerous nodular vesicles. Histologically, these organs were replaced by numerous collapsed vesicles demarcated by fibrous tissues. The cysts lined by a cellular, germinal layer contained numerous brood capsules with abundant production of well-developed protoscolices. Protoscolices were about 80–100 μm in diameter, and had hooks being visible as refractive structures. This zoo locates in the east of Hokkaido where is an endemic area of Echinococcus multilocularis infection. From epidemiology and pathological findings, this animal was diagnosed as E.multilocularis infection. This report describes the pathology of... |

| The aim of this study was to analyze changes in the skeletal muscle tissue of rats after muscle stretch injury using fractal analysis. Nineteen rats were divided into three groups, Control (n= 5) (C), Lesion two days (n= 7) (L2), and Lesion seven days (n= 7) (L7). Histological slides of the gastrocnemius muscle of the animals were prepared and stained with Hematoxylin and eosin for analysis of the inflammatory process, and picrosirius for the demonstration of collagen. The stained slides were subsequently analyzed using Fractal Dimension (FD). The results showed high FD values of the inflammatory process in the experimental groups L2 and L7 in relation to C (p= 0.000). The analysis of collagen in the picrosirius stained slides showed high FD in the L2... |

| The purpose for the present study was to determine the frequency of sella turcica bridge and clinoid enlargement on lateral cephalometric plain film radiography from peruvians patients who attended our radiological center and identify any possible genre or age group associations. The sella turcica from 417 lateral cephalometric plain film radiography was evaluated in order to determine the presence of sella turcica bridge (fusion between the anterior and posterior clinoid process) or clinoid enlargement related to the Sella (S) cephalometric point. The sella turcica bridge and clinoid enlargement frequency was 4.31% (n=18), and 16.3% (n=68). Cramer´s V and ETA statistics found, by separately, non significant association (p > 0.05) between sella turcica... |

| The gastric compartments of ten cetaceans stranded on the coast of Ceará State, Northeast Brazil were analyzed in this study. Gastric Anisakis spp. was diagnosed in all individuals involved in this study. Parasites and tissue samples were collected during necropsy. The presence of Anisakis parasites showed similar distribution across the three gastric compartments and the majority was free within the gastric lumen. Macroscopically, the lesions were predominantly characterized by the presence of ulcers (60%, 6/10) within the gastric mucosa, occasionally associated with edema and hemorrhage (30%, 3/10). Eight cetaceans (8/10 - 80%) presented gastric microscopic alterations and in 75% (6/8) of these animals, chronic lymphoplasmocytic gastritis was observed... |

| A study of the growth and mortality of the European oyster Ostrea edulis , including the effects of Marteilia refringens and Bonamia ostreae , was carried out in three oceanic areas in the Bay of Arcachon from May 1989 to February 1991. One-year-old spat, free from disease were used for the trials. Six months after beginning the trials, Marteilia refringens had severely infested the cultures. Although Bonamia ostreae was found during the first year, the rate of infestation was low. In the second year bonamiasis increased and high mortality (> 60%) occurred in Ostrea edulis populations. Although the growth of the oysters was good, their condition index was generally poor. Moreover, shell perforations by Polydora sp. were observed. The influence of... |

| An infection caused by a Perkinsus -like parasite has been observed in Ruditapes decussatus from Portugal (Comps and Chagot, 1987). Following a pathological study carried out on clams affected by mortalities in the Algarve area, this parasite was found again, inducing a reaction process in the host. Histological examination reveals the parasite in the connective tissue of different organs. The adjoining tissues, particularly the epithelia, are not affected. |

| ABSTRACT The objective of this study was to compare the histopathological aspects of the liver of free-living and farmed bullfrogs (Lithobates catesbeianus). Thirty liver samples were collected from young and adult bullfrogs in the states of Minas Gerais and Rio de Janeiro, Brazil. Marked blood congestion and even hemorrhage and a large number of melanomacrophages were observed in most of the livers from free-living bullfrogs. Additionally, hepatocytes showed cytoplasmic eosinophilia and some showed nuclear hypertrophy and presence of microvesicular steatosis; small foci of infiltrates of mononuclear cells were observed in some samples, as well as a thicker capsule. In the farmed bullfrogs, cytoplasmic rarefaction was normal. Morphologically, unlike the... |

| Depuis l’assec du canal d’alimentation en 2004 après le passage du cyclone Gafilo, on a constaté une augmentation massive de la densité d’Upogebia spinimanus au sein de la ferme de l’AQUALMA-Besalampy. En cas d’apparition d’une nouvelle maladie des crustacés, ce phénomène constituerait un grand risque en favorisant sa transmission chez les crevettes élevées, voire les consommateurs. Une nouvelle méthode d’approche installée par le laboratoire centrale de l’AQUALMA s’intéresse sur la prévention des risques de maladie liée à la biosécurité, en même temps des crevettes, des consommateurs et de l’environnement. Par conséquent, durant ce 5 mois de stage, des pratiques sur terrain et en laboratoire au moyen de différentes expériences à noter le suivi... |

| The French network for the surveillance and monitoring of mollusc health (REPAMO) was officially set up in 1992 to control the shellfish status along the French coasts according to the European directives 91/67/EEC and 95/70/EC. The objectives are 1) the surveillance of notifiable diseases present in France (Bonamiosis and Marteiliosis of flat oysters Ostrea edulis), 2) the surveillance of health status of cultured and wild populations of molluscs, 3) the study of abnormal mortality and 4) the control of exchanges from European and third countries. In this context, a new surveillance programme, called Active Targeted Survey, part of the REPAMO, was applied in 2004 in order to improve the monitoring of the health status of the French mollusc populations... |

| ABSTRACT: This report described clinical, epidemiological, and pathological aspects of ischemic myelopathy caused by fibrocartilaginous embolism (FCE) in a 10-year-old, mixed breed gelding. Clinically, the horse presented acute hind limbs paralysis, with a clinical course of approximately 24 hours. At necropsy, no gross lesions were observed. Cross-sections of the spinal cord revealed focally extensive areas of malacia from the T10 to L4 segments. Focally extensive areas of liquefactive necrosis involving the gray matter and adjacent white matter were observed on histologic sections. The lumen of multiple blood vessels in the periphery of the necrotic areas was occluded by fibrocartilaginous emboli that strongly stained with alcian blue. Clinical signs,... |

| Introduction: Through the combined works of research, local communities and professionals, a new activity has been created, "vénériculture", i.e. clam farming. Thanks to the knowledge acquired in research as well as production in the shellfish field, clam production results followed shortly thereafter. Rightly so, only 10 years have elapsed since the beginning of the research and the actual production phase (500 t) involving about 300 professionals. Research conducted by IFREMER positively contributes to the creation of new trades as well as diversity within existing professions. Clams are marketed nationally as well as exported. French producers are truly competent, but the prospect of open borders and increasing competition requires maintaining a high... |
