L'inquinamento ha un impatto sulle infezioni endoparassitarie nei pesci d'acqua dolce
Dai risultati di questo studio si pu concludere che il tasso di infezione degli endoprotozoi stato pi alto nei pesci d'acqua dolce di allevamento rispetto ai pesci selvatici (lago Borullus), inoltre la stagione estiva ha registrato il tasso di infezione pi alto e i protozoi pi prevalenti nella stagione estiva sono stati Eimeria spp ed Entamoeba in O. niloticus mentre in C. gariepinus i parassiti ematici sono stati gli endoprotozoi pi isolati Trypansoma e Babesia. Lo stato di salute dei pesci esaminati (Oreochromis niloticus e Clarias garipinus) stato influenzato in modo significativo da parametri dell'acqua come i composti azotati e lo stato batteriologico. I valori della conta batterica totale e dei coliformi totali sono risultati correlati positivamente con i fertilizzanti organici. Sono state riscontrate correlazioni positive tra l'acqua (composti azotati e stato batteriologico) e il tasso di infezione degli endoprotozoi. La concentrazione di metalli pesanti (Fe, Mn, Zn, Cu, Pb, Cd e Hg) nell'acqua risultata pi elevata nelle aziende agricole rispetto al lago Borullus. Nessuna correlazione tra il tasso di infezione e i livelli di metalli pesanti nell'acqua. La concentrazione di metalli pesanti negli organi segue la sequenza fegato > branchie > muscoli. Correlazione negativa tra i residui di metalli pesanti nei tessuti dei pesci e il tasso di infezione.
La pollution a un impact sur les infections endoparasitaires chez les poissons d'eau douce
Les r sultats de cette tude permettent de conclure que le taux d'infection par les endo-protozoaires tait plus lev chez les poissons d'eau douce d' levage (fermes piscicoles) que chez les poissons sauvages (lac Borullus), que la saison estivale pr sentait le taux d'infection le plus lev et que les protozoaires les plus r pandus pendant la saison estivale taient Eimeria spp et Entamoeba chez O. niloticus, tandis que chez C. gariepinus, les parasites sanguins taient les plus isol s, Trypansoma et Babesia. L' tat de sant des poissons examin s (Oreochromis niloticus et Clarias garipinus) a t affect de mani re significative par les param tres de l'eau tels que les compos s azot s et l' tat bact riologique. Les valeurs de la num ration bact rienne totale et de la num ration des coliformes totaux sont en corr lation positive avec les engrais organiques. Il y avait des corr lations positives entre l'eau (compos azot et statut bact riologique) et le taux d'infection des endo-protozoaires. La concentration en m taux lourds (Fe, Mn, Zn, Cu, Pb, Cd et Hg) dans l'eau tait plus lev e dans les fermes que dans le lac Borullus. Aucune corr lation entre le taux d'infection et les niveaux de m taux lourds dans l'eau. La concentration de m taux lourds dans les organes est la suivante: foie > branchies > muscles. Corr lation n gative entre les r sidus de m taux lourds dans les tissus des poissons et le taux d'infection.
Verschmutzung wirkt sich auf endoparasitäre Infektionen bei Süßwasserfischen aus
Aus den Ergebnissen dieser Studie konnte geschlossen werden, dass die Infektionsrate von Endoprotozoen bei gez chteten S wasserfischen (Fischfarmen) h her war als bei Wildfischen (Borullus-See), au erdem war die Infektionsrate in der Sommersaison am h chsten, und die vorherrschenden Protozoen in der Sommersaison waren Eimeria spp. und Entamoeba bei O. niloticus, w hrend bei C. gariepinus Blutparasiten am h ufigsten isoliert wurden. Der Gesundheitszustand der untersuchten Fische (Oreochromis niloticus und Clarias garipinus) wurde erheblich von Wasserparametern wie Stickstoffverbindungen und bakteriologischem Status beeinflusst. Die Werte der Gesamtbakterienzahl und der Gesamtcoliformenzahl korrelierten positiv mit organischen D ngemitteln. Die Schwermetallkonzentration (Fe, Mn, Zn, Cu, Pb, Cd und Hg) im Wasser war in den Farmen h her als im Borullus-See. Die Schwermetallkonzentration in den Organen folgt der Reihenfolge Leber > Kiemen > Muskeln. Negative Korrelation zwischen Schwermetallr ckst nden in Fischgeweben und Infektionsrate.
A poluição tem impacto na infeção endoparasitária em peixes de água doce
Os resultados deste estudo permitem concluir que a taxa de infe o de endoprotozo rios foi mais elevada nos peixes de gua doce cultivados (pisciculturas) do que nos peixes selvagens (Lago Borullus), e que a esta o do ver o foi a que registou a taxa de infe o mais elevada e que os protozo rios mais prevalecentes na esta o do ver o foram a Eimeria spp e a Entamoeba em O. niloticus, enquanto que em C. gariepinus os parasitas sangu neos foram os Trypansoma e a Babesia mais isolados. O estado de sa de dos peixes examinados (Oreochromis niloticus e Clarias garipinus) foi significativamente afetado pelos par metros da gua, tais como o composto azotado e o estado bacteriol gico. Os valores da contagem bacteriana total e da contagem total de coliformes correlacionaram-se positivamente com os fertilizantes org nicos. Houve correla es positivas entre a gua (composto azotado e estado bacteriol gico) e a taxa de infe o de endoprotozo rios. A concentra o de metais pesados (Fe, Mn, Zn, Cu, Pb, Cd e Hg) na gua foi mais elevada nas explora es do que no lago Borullus. N o h correla o entre a taxa de infe o e os n veis de metais pesados na gua. A concentra o de metais pesados nos rg os a seguinte: f gado > br nquias > m sculos. Correla o negativa entre os res duos de metais pesados nos tecidos dos peixes e a taxa de infe o.
Zanieczyszczenia wplywają na infekcje endopasożytnicze u ryb slodkowodnych
Na podstawie wynik w tego badania można stwierdzic, że wskaźnik zarażenia endoprotozoa byl wyższy u hodowlanych ryb slodkowodnych (hodowle ryb) niż u ryb dzikich (jezioro Borullus), r wnież sezon letni mial najwyższy wskaźnik zarażenia, a najbardziej dominującymi pierwotniakami w sezonie letnim byly Eimeria spp i Entamoeba u O. niloticus, podczas gdy u C. gariepinus pasożyty krwi byly najczęściej izolowanymi endoprotozoa Trypansoma i Babesia. Stan zdrowia badanych ryb (Oreochromis niloticus i Clarias garipinus) byl znacząco uzależniony od parametr w wody, takich jak zawartośc związk w azotowych i stan bakteriologiczny. Og lna liczba bakterii i og lna liczba bakterii z grupy coli korelowaly dodatnio z nawozami organicznymi. Stężenie metali ciężkich (Fe, Mn, Zn, Cu, Pb, Cd i Hg) w wodzie bylo wyższe w gospodarstwach niż w jeziorze Borullus. Stężenie metali ciężkich w narządach bylo następujące: wątroba > skrzela > mięśnie. Ujemna korelacja między pozostalościami metali ciężkich w tkankach ryb a wskaźnikiem infekcji.
