Riassunto
Il progressivo aumento di richieste di carpe koi di qualità e di elevati costi degli ultimi anni, pone sempre più l’esigenza di capire l’effettivo stato di salute dei pesci, apparentemente sani, importati in numero sempre maggiore in Italia. Partendo dall’origine delle carpe koi e dalla storia spesso leggendaria del suo allevamento, abbiamo trattato in maniera introduttiva la loro biologia, anatomia e fisiologia per poter analizzare in maniera efficace i maggiori agenti patogeni e le principali malattie, verificando i vari metodi di diagnosi e la sensibilità dei test diagnostici nel rivelamento di agenti eziologici in soggetti considerati portatori asintomatici. Sono stati presi in esame soggetti importati direttamente dal Giappone, circa 20 soggetti in rappresentanza dei 100 totali importati. I rivelamenti sono stati effettuati in diversi periodi dell’anno (inverno, primavera ed estate). Iniziando con il primo quello invernale il 27 gennaio2020, seguito da quello primaverile l’11 maggio 2021 e per finire in estate il 28 settembre 2021. La ricerca ha avuto come soggetti principali gli agenti batterici, virale e parassitari più frequentemente riscontrati nelle carpe koi. Quelle virologiche hanno preso in esame il virus della viremia primaverile della carpa (SVC), gli Herpesvirus 1 e 3 e il virus dell’edema della Carpa (CEV). Le indagini batteriologiche si sono incentrate particolarmente sulla ricerca di Aeromonas spp.,Pseudomonas spp., Vibrio spp., Flavobacterium spp. e Mycobacterium spp.. Mentre per le ricerche parassitarie la nostra indagine ha riguardato i micro e macro-parassiti esaminando la cute, le branchie e il sangue. Il nostro studio conferma l’importanza dei test diagnostici per garantire lo stato di salute di questi meravigliosi gioielli viventi di nuova importazione.
2 ABSTRACT
The progressive increase in requests for quality koi carp and high costs in recent years, increasingly raises the need to understand the actual state of health of the fish, apparently healthy, imported in increasing numbers in Italy. Starting from the origin of the koi carp and the often legendary history of its breeding, we have dealt with their biology, anatomy and physiology in an introductory way in order to be able to effectively analyze the major pathogens and the main diseases, verifying the various methods of diagnosis and the sensitivity of diagnostic tests in the detection of etiological agents in subjects considered asymptomatic carriers. Subjects imported directly from Japan were examined, around 20 subjects representing the total 100 imported. The revelations were made at different times of the year (winter, spring and summer). Starting with the first one in winter on January 27, 2020, followed by the spring one on May 11, 2021 and ending in summer on September 28, 2021. The main subjects of the research were the bacterial, viral and parasitic agents most frequently found in koi carp. Virological studies examined carp spring viremia virus (SVC), herpesviruses 1 and 3 and carp edema virus (CEV). The bacteriological investigations have focused particularly on the search for Aeromonas spp., Pseudomonas spp., Vibrio spp., Flavobacterium spp. and Mycobacterium spp.. While for parasitic research our investigation concerned micro and macro-parasites by examining the skin, gills and blood. Our study confirms the importance of diagnostic tests to guarantee the state of health of these wonderful newly imported living jewels.
