Idesia [online]. ISSN Seriola lalandi is a fish that has described their reproductive biology in wild specimens. In particular, the gonadal maturation of this fish has variations by sex and length of each individual. However, fish in captivity, as in the case of cultivation in Aquaculture Recirculation System SAR , for fattening and subsequent marketing, has not yet been described their gonadal development and its association with long or weight of fish. These were euthanized in order to conduct the corresponding autopsy, removing the gonads, to which were applied Histological Techniques routine Hematoxylin - Eosin and Histochemical Techniques Picro - Fuchsin Van Gieson and Periodic Acid Schiff.

Gross and histopathological findings of the dog suggested hermaphroditism with bilateral ovotestes and pyometra. Keywords: dog; hermaphrodite; os clitoridis; ovotestis; pyometra Hermaphrodite means an animal or a human being in which male and female sex organs are present simultaneously, or in which the sex organs contain both ovarian and testicular tissue [ 3 ].

Gonads and the evolution of hormonal phenotypes.

Sometimes one gonad becomes a testis while the other becomes an ovary; sometimes the gonads become ovotestes containing a mixture of male and female components [ 1 ]. Although hermaphroditism is often associated with infertility, that is not always the case.

Hermaphroditism occurs rarely in human and animal populations [ 5 ]. Only few cases of hermaphrodite have been reported in various breeds of dogs such as Basset hound [ 2 ], Cocker spaniel [ 7 ] and Pug [ 8 ].

Here, we report a very rare case of a hermaphrodite dog. Hermaphroditism was identified in a 3-year-old American Cocker spaniel with external female appearance.

The dog was presented due to vaginal discharge, loss of appetite. Epub Feb Mechanism of inhibition of human secretory phospholipase A2 by flavonoids: rationale for lead design. J Comput Aided Mol Des. Epub Aug Flavonoids affect actin functions in cytoplasm and nucleus.

Since gastropods are indicator of pollution in marine environment 3 , it might be that the C. In the same area Nasipit, Agusan del Norte it was reported that there are occurrences of imposex in some gastropods species like the Thais tuberosa and Cronia margariticola 4.

Imposex or pseudohermaphrodism is a widespread phenomenon among prosobranch molluscs characterized by the development and superimposition of non-functional male accessory sex organs i. Aside, it was observed that the operculum of imposex is much wider compared to female and male.

However, the male gastropod operculum is wider compared to a normal female 6. The incidence of imposex in gastropods is a worldwide concern and has been studied in many gastropods 3 , 7 , 8 , 9.

This phenomenon is caused by exposure to Tributyltin compound and results in accumulation of testosterone in the gastropods 10 , Tributyltin is the most commonly used antifouling agent used in paints for the underwater hull of large boats It was used to kill the algae, mussels and barnacles found in the hulls of the vessels which are a historic problem that hinders the operation of marine vessels. The use of imposex standard indices will be established to evaluate the incidence of imposex in other gastropod species in Nasipit, Agusan del Norte considering that it is an inexpensive method to establish occurrence, patterns and changes in TBT pollution in marine environment.

However, for the future studies, this analysis will be carried out. This study is very essential in on the reproductive condition of C. There is no study conducted in this gastropod in the incidence of imposex, morphological and histological characterization of gonads.
