The aim of this study was to determine the level of contamination of public plazas in the city of Temuco with parasitic forms through dog faeces. A total of 102 faecal samples were collected in eight plazas of the city centre. Samples were processed by the sedimentation-flotation method (Teuscher method). The 89.2% of the samples resulted positive for a parasitic form, where strongyle-type eggs (69.6%) within the Phylum Nematoda and the oocysts of Isospora within the Phylum Protozoa (6.8%) were the most frequent. Half of the samples were poliparasitic where the triparasitism reached 21.5% of all samples. The findings indicate a polluted environment and poor waste management in the city center.

Mucus is one of the most important components of fish immunity, it contains components of innate immunity such as glycoproteins, lysozyme, complement proteins, proteolytic enzymes, antimicrobial peptides and immunoglobulins. Current information concerning the generation, physiology and effects of mucus in Atlantic salmon is reviewed, as well as possible mucogenic additives for the control of parasites that may be attractive for future use in the reduction of Caligus rogercresseyi. A full-text multidisciplinary data search was carried out. The topics included in the research process correspond to salmon, mucus, and mucogenic additives. It was found that the additive that generates a greater increase of the mucus components is the probiotic Bacillus sp. The findings suggest that more research is needed to unravel the implications of skin mucosal immunity on fish welfare and diseases of bio...
