This paper describes the in vitro cultivation of the 3rd-larval stage (L3) of Anisakis simplex to adulthood in a much simpler and easier to prepare medium than those described to date. The adult males obtained are between 3.8 and 6.5 cm long and the females between 4.5 and 8.0 cm. Some individually cultivated females laid eggs which had an average size of(More)
This is the first demonstration of the in vitro development of the 3rd-stage larvae (L3) of Hysterothylacium aduncum to the adult. This was achieved in a semi-defined medium that is easy to prepare and to reproduce. The L3, collected from the peritoneal cavity of horse mackerel (Trachurus trachurus), were individually inoculated into RPMI-1640 medium +20%(More)
The existence of sibling species is widespread among nematodes and the recognition of these has important epidemiological implications. In an attempt to establish whether this is the case for Hysterothylacium fabri, which is present in many Mediterranean fish species, we studied its genetic diversity and analysed its population structure. To do this, we(More)
A total of 301 blue whiting, Micromesistius poutassou Risso, 1826, ranging in length from 17 to 28 cm, from Motril Bay (Mediterranean coast, south Spain) were examined for anisakid nematodes, as these fish are common items in the Spanish Mediterranean diet. Three anisakid species were morphologically identified with a total prevalence of 10.63%. Anisakis(More)
We studied the parasitization by Anisakis spp. in European hake (Merluccius merluccius) of 40–52 cm from the Atlantic off northwest Africa and the Mediterranean off southern Spain. Infection parameters differed: The fish from the Atlantic showing a prevalence of 87.97% and a mean intensity of 4.69, while, in those from the Mediterranean, these were 41.27%(More)
An epidemiological survey of anisakids was carried out on 209 specimens of greater forkbeard (Phycis blennoides) and 58 of forkbeard (Phycis phycis) captured off the Mediterranean coasts of Andalucía (southern Spain). Four species of nematodes were identified: Anisakis simplex s.l., Anisakis physeteris, Hysterothylacium aduncum and Hysterothylacium fabri.(More)
In view of the lack of an effective pharmacological treatment against human anisakiosis, a disease produced by L(3) larvae of the genus Anisakis present in raw fish, we studied the in vivo larvicidal effect of certain monoterpenic derivatives against L(3) of A. simplex s.l. The aldehydic monoterpene citral and the alcoholic citronellol, when they are(More)
Anisakis morphotype I is the principal etiologic agent of human anisakiasis, with differences in pathogenicity found between the Anisakis simplex s.s. and A. pegreffii species; however, the role of morphotype II larvae in this illness is not well understood. The purpose of this study is to verify the ability of morphotype II larvae to invade tissues via the(More)
Staphylococcus aureus contamination of foods is one of the most prevalent causes of gastroenteritis worldwide, which is caused by ingestion of preformed toxins. Ready-to-eat foods without previous heat treatment before consumption are susceptible to be contaminated during processing, storage or handling at both retail points and domestic homes. In this(More)
Cross contamination is one of the most important contributing factors in foodborne illnesses originating in household environments. The objective of this research was to determine the transfer coefficients between a contaminated domestic slicing machine and a cooked meat product, during slicing. The microorganisms tested were Staphylococcus aureus (Gram(More)
