Fish viruses and fish viral diseases.

FISH in pathology.

This critical review summarizes the knowledge about fish skeletal tissues and inherent normal and anomalous development. Particular emphasis is given to existing literature on reared European fishes. The aim was to identify the main gaps of knowledge that require to be filled, in order to precociously identify anomalous developmental patterns that lead to skeletal anomalies in reared finfish larvae and juveniles. The review also aims to extend our knowledge about the factors that are possibly involved in the onset of skeletal anomalies. The final goal is the optimization of the morphological quality of farmed juvenile fish.

Skeletal Anomalies in Reared European Fish Larvae and Juveniles. Part 1: Normal and Anomalous Skeletogenic Processes

The common goldfish is the most widespread teleosts in the world. Due to its peculiar characteristics, such as the high resistance, easy availability and stabulation, and for its evolutionary characteristics, this fish lends itself to be one of the most used experimental models. This study aimed to characterize the mast cells in the intestine of Carassius auratus using anti-TLR-2, anti-S100, anti-VIP, anti-serotonin (5-HT) and anti-Piscidin antibodies. The intestine of goldfish, like that of all vertebrates, plays an important role in the immunology of the animal. The gut-associated lymphoid tissue GALT is an immune component containing several specific cells such as lymphocytes, macrophages and mast cells. In addition, the presence of goblet cells in the intestinal epithelium strengthens the defence system, secreting many cytokines and chemokines and displaying antibacterial properties. Our results show mast cells labelled with antibodies that are highly conserved between fish and mammals, demonstrating an active role of these cells in the immune response.

Microbiology of leprosy

In fish there is an innumerable variety of neoplasias that arise essentially from all cell types. Neolasia here, we will focus on the neoplasias that appear spontaneously in these animals and will not cover the experimentally induced neoplasias and/or the animal models of neoplasias. As for diagnosis, in general, specialists in aquatic organism pathology are not so familiar with the diagnosis of neoplasias. Infectious pathology, as opposed to non-infectious pathology, is the predominant condition in this area and, of course, these are of greater importance because some infectious diseases generate great economic losses, while neoplasias are isolated pathologies, with some exceptions. 
In the last 20 years, 10 neoplasias in different species have been diagnosed in our laboratory, and we reported their characteristics in this paper. We also made a detailed bibliography review and observed how 90 neoplasias among 56 species of teleosteal fish were reported. 
Neoplasias in fish, unlike other diseases, do not generate great losses to aquaculture. However, the true value of neoplastic pathology compared is to better understand the histiogenesis and biological behavior of neoplasias in mammals and humans. Carcinogenesis is generally complex and in most neoplasias in both mammals and fish, the origin is unknown, and it seems that there are many factors that contribute to the onset and growth of neoplasias.

Neoplasias in Fish: Review of the Last 20 Years. A Look from the Pathology

Mycobacteria are widespread in the natural environment, both in terrestrial and aquatic environments, and some species can be zoonotic. In aquatic organisms, especially in fish and crustaceans, they are diagnosed with certain frequency. Taking into account that mycobacteria affecting fish, as well as the species causing leprosy, have less mycolic acid, the authors used the Fite-Faraco (FF) technique in this work and compared it with the classic Ziehl Neelsen (ZN) staining. In the Laboratory of Immunology and Pathology of Aquatic Organisms (LIPOA), the authors chose from their tissue archive tissue material belonging to 10 specimens of fish of different species, belonging to LIPOA, which were reported cases over a period of 15 years (from 2002 to 2017). The Original Research Article Romano et al.; AJRAVS, 6(1): 27-34, 2020; Article no.AJRAVS.59001 28 specimens had in common the presence of lesions classified as granulomatous inflammation, but with the ZN technique it was not possible to obtain a definitive diagnosis of mycobacteriosis. The authors observed that in tissues from fish infected with Mycobacteria, the FF technique was more useful, since the presence of bacilli can be observed, where previously the ZN technique was used and no bacilli were observed.

Several types of maxilla deformities have been reported in various species of fish. In salmonids, the maxilla deformities are observed with frequency. Here we report eight cases of a rainbow trout, five females and three males, adult, with upper maxilla foreshortening. The specimens studied came from an establishment located in the fish farmer located in the Patagonia, Argentina.

Lymphocystis disease has been reported worldwide in several species of freshwater fish and marine fish, naturally infected in the wild environment, or in intensive crops in farms. Nodular warty lesions of irregular surface were observed in the tegument and fins and mouth in a species of croaker (Micropogonias furnieri) caught in Cassino beach Rio Grande RS, Brazil and flounder (Paralichthys orbignyanus) caught in the city of San Clemente, Argentina. The skin lesions fragments were fixed in 20% buffered formalin, and the histological sections were stained with hematoxylin and eosin and Original Research Article Pedrosa et al.; AJRIZ, 3(3): 29-36, 2020; Article no.AJRIZ.60333 30 Periodic Acid-Schiff (PAS), where microscopic alterations were visualized in the form of hyaline capsule with small basophilic structures in nodules and fibroblastic cells proliferation. The reported cases were based on the disease macroscopic findings characteristic of a lymphocystis disease, along with the histopathology, which confirmed the presence of the disease in the analyzed tissues.

Tunics hyperplasia of blood vessels can be quantified by a range of techniques that relate to modifications of area or thickness on histological sections. We studied hyperplasia of tunics of coronary arteries in a fish species, Rachycentron canadum for establishing the relationship between tunics and luminal obstruction by morphometry. The morphometric analysis was performed on 158 arterial vessels of 40 fish samples. The histological slides of cardiac and vascular tissue were stained using hematoxylin and eosin and observed under an optical microscope. The data relating to the proportion of the lumen area compared to the area of the tunic Original Research Article Pedrosa et al.; AJRIZ, 4(1): 40-48, 2021; Article no.AJRIZ.67057 41 media were analyzed according to Beta regression models. The lumen proportion showed a decreasing relationship with weight and length of the analyzed animals. A linear relationship was not observed between lumen proportion and areas and/or radius of arterial tunics. It is concluded that the increase in weight gain contributes to a reduction of lumen area, leading to arterial obstruction without increasing or decreasing relationship between the proportion of vascular lumen and the thickness of arterial tunics. The set of abnormalities described are likely to be attributed to nutritional factors during the fish cultivation.
