    Journal: Rev Bras Parasitol Vet; 2013; 22(4):602-4. PubMed ID: 24473889.
    Abstract:
    This paper describes the frequency and number of Sphyrion laevigatum in the skin of Genypterus blacodes, an important economic resource in Chile. The analysis of a spatial distribution model indicated that the parasites tended to cluster. Variations in the number of parasites per host could be described by a negative binomial distribution. The maximum number of parasites observed per host was two.
