| 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... |

| Bonamiosis was first reported in association with mass mortality of flat oysters, Ostrea edulis, in June 1979 in L'Ile Tudy, Brittany. The disease rapidly spread to all of the oyster farming areas in France but also in other European countries. The French flat oyster production, which already suffered from another protozoan disease, marteiliosis, decreased from 5500 mt in 1979 to less than 2000 mt after 1980. In 2001, about 350 French farms sell 1650 mt of flat oysters. This production mainly relies on natural spat collection which specially occurs in Quiberon bay. One third of this spat is transferred from South to North Brittany for further growth. Quiberon bay constitutes an interesting site regarding the surveillance of bonamiosis because of the... |

| 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 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... |

| 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... |

| 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... |

| 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... |

| An epizootiological study of the mayor deseases affecting the penaeid shrimp Penaeus vannamei was performed from june 1994 throuh august, 1995 in tree farms located on the colombian Carebbean coast. The presence and prevalence of infectious agents such as bacteria, protozoa, viral inclusions bodies and changes histopatologicals was determinated by means of gross examination and histological analysis.. The relationship between these infection agents and specific disease was also studies. The presence of some viruses such a Baculovirus penaei, IHHNV, TSV and LOVV, were determinated by demostration of the cytopathical effects characteristic of these agent. Additionaly, a logistic regression analysis was used to determine the relationship between some clinical... |

| An upsurge in the prevalence of rusty-yellow discoloration of the skin of the two tilapia species, being cultured at the African Regional Aquaculture Centre (ARAC), gave a basis for an urgent clinical and epizootiological studies of the condition. The studies were therefore carried out along with the performance of some catfishes in polyculture with Oreochromis niloticus, under the integrated poultry cum fish farming system. It was observed that this condition affects the tilapia species only, and the antemortem, and postmortem examination revealed that the discolouration is restricted to the surface of the cutaneous tissue; affecting the underside of the exposed part of the scales, the fins and the skin flap covering the scale pockets, mostly in adult... |

| 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... |

| 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 Newcastle disease is a highly contagious disease responsible for major outbreaks and considerable economic losses in the poultry industry in China. There is still little information available regarding gene characterization of the NDV, especially in ducks and pigeons. Therefore, the aim of this study was to investigate NDV isolated from ducks and pigeons in Hubei, China. In this study, three NDVs from ducks and pigeons were isolated between 2013 and 2015.The fusion protein (F) gene of the NDV isolates was sequenced and phylogenetically analyzed. The clinical signs and gross histopathological lesions were examined. Phylogenetic analysis of these strains indicated that all the sequences are classified as genotype II. The isolates shared a 112... |

| 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... |
