ABSTRACT
This research was aimed to explore the helminth parasitic diseases in Schizothorax plagiostomus (the snow trout) from river Swat and river Panjkora, Pakistan. Collection of 360 fish specimens have done from the lower, middle and upper reaches of both the rivers through gill nets, cast nets, dragon nets and hooks. All the samples were examined in the University of Malakand, Zoology Department for helminth parasites during the months from January 2015 to December 2016. Of the total examined fish samples 21.9% (n=79) were infected with Rhabdochona spp including 17.7% (n=32/180) in river Swat and 26.6% (n=47/180) in river Panjkora. Highest month-wise prevalence (p=0.09878,p<0.05) was reported in May (30%), then by February and October each (26.6%) while the lowest during August (13.3%). Highest prevalence (p=0.9723, p<0.05) was reported in summer season (26.6%), while lowest in the winter season (20%). Adults were highly infected (p=< 0.0001) in prevalence (63.7%) followed by sub-adults (13.2%) while no infection was found in juvenile specimens. Females fish samples had higher (p=0.0277, p>0.05) prevalence (28.8%) than males (16.6%). Fishes of the lower reaches had highest (p=0.0029, P>0.05) prevalence (31.7%) followed by middle reaches (16.5%) while the lowest prevalence was observed in samples of fish collected from upper reaches (9.87%). Present study address that Rhabdochona spp in the intestine of snow trout has a long term relationship and call as a natural infection in cyprinids and zoonotic risk to human.
RESUMO
Esta pesquisa teve como objetivo explorar as doenças parasitárias por helmintos em Schizothorax plagiostomus (a truta das neves) do rio Swat e do rio Panjkora, Paquistão. A coleta de 360 espécimes de peixes foi feita nos trechos inferior, médio e superior de ambos os rios por meio de redes de emalhar, de lançamento, de dragão e anzóis. Todas as amostras foram examinadas na Universidade de Malakand, Departamento de Zoologia, para helmintos parasitas durante os meses de janeiro de 2015 a dezembro de 2016. Do total de amostras de peixes examinadas, 21,9% (n = 79) estavam infectados com Rhabdochona spp, incluindo 17,7% (n = 32/180) no rio Swat e 26,6% (n = 47/180) no rio Panjkora. A maior prevalência no mês (p = 0,09878, p <0,05) foi relatada em maio (30%), depois em fevereiro e outubro cada (26,6%), enquanto a menor em agosto (13,3%). A maior prevalência (p = 0,9723, p <0,05) foi relatada no verão (26,6%), enquanto a menor no inverno (20%). Os adultos foram altamente infectados (p = <0,0001) na prevalência (63,7%), seguidos por subadultos (13,2%), enquanto nenhuma infecção foi encontrada em espécimes juvenis. As amostras de peixes do sexo feminino tiveram maior (p = 0,0277, p> 0,05) prevalência (28,8%) do que o masculino (16,6%). Os peixes do curso inferior tiveram maior (p = 0,0029, P> 0,05) prevalência (31,7%) seguida do curso médio (16,5%), enquanto a menor prevalência foi observada em amostras de peixes coletados do curso superior (9,87%). O presente estudo aborda que Rhabdochona spp no intestino da truta das neves tem uma relação de longo prazo e pode ser considerada uma infecção natural em ciprinídeos e risco zoonótico para humanos.
