occurrence of anthropozoonotic parasitic infections and faecal microbes in free ranging sperm whales physeter macrocephalus from the mediterranean sea
Parasitology Research, 2018Co-Authors: Carlos Hermosilla, J M Brotons, Ellen Prengerberninghoff, Magdalena Cerda, Jorg Hirzmann, Christa Ewers, Liliana M. R. Silva, Anja TaubertAbstract:Sperm whales (Physeter macrocephalus) are the largest toothed whales and only living member of family Physeteridae. Present survey represents first report on cultivable faecal microbes and gastrointestinal helminths and protozoans infecting free-ranging sperm whales inhabiting Mediterranean Sea waters surrounding Balearic Archipelago, Spain. Twenty-five individual sperm whale scat samples, including one calf, were collected without disturbance of animals during the summer of 2016. Parasitological diagnostic methods, such as sodium acetate acetic formalin (SAF) method, carbol fuchsin-stained faecal smears, Giardia/Cryptosporidium coproantigen ELISAs and an Anisakis-specific PCR were applied for further identification. Five bacterial genera, i.e. Acinetobacter, Clostridium, Enterococcus, Staphylococcus and Streptococcus, and one fungus namely Cladosporium were identified. Parasitological infections included seven different parasite species with some of them bearing anthropozoonotic potential. Thus, four of these parasites were zoonotic, i.e. Anisakis, Balantidium, Diphyllobothriidae gen. sp. and Giardia. Additionally, Zalophotrema curilensis eggs, spirurid-like eggs and Cystoisospora-like oocysts were identified. Molecular characterization identified Anisakis physeteris as the species infecting these whales. This survey provides first records on occurrence of two zoonotic enteropathogenic protozoan parasites (Giardia and Balantidium) and of facultative pathogenic bacteria (Clostridium and Enterococcus) in sperm whales. Presented data should be considered as a baseline study for future monitoring surveys on anthropozoonotic pathogens affecting free-living sperm whale populations and enhance investigations on possible impact on public health as well as on isolated Mediterranean sperm whale subpopulation.

endo and ectoparasites of large whales cetartiodactyla balaenopteridae Physeteridae overcoming difficulties in obtaining appropriate samples by non and minimally invasive methods
International journal for parasitology. Parasites and wildlife, 2015Co-Authors: Carlos Hermosilla, Liliana M. R. Silva, Anja Taubert, Rui Prieto, Sonja Kleinertz, Monica A SilvaAbstract:Baleen and sperm whales, belonging to the Order Cetartiodactyla, are the largest and heaviest existent mammals in the world, collectively known as large whales. Large whales have been subjected to a variety of conservation means, which could be better monitored and managed if physiological and pathophysiological information, such as pathogen infections, could already be gathered from free-swimming animals instead of carcasses. Parasitic diseases are increasingly recognized for their profound influences on individual, population, and even ecosystem health. Furthermore, a number of parasite species have gained importance as opportunistic neozoan infections in the marine environment. Nonetheless, traditional approaches to study parasitic diseases have been impractical for large whales, since there is no current routine method for the capture and handling of these large animals and there is presently no practical method to obtain blood samples remotely from free-ranging whales. Therefore, we here not only intend to review the endo- and ectoparasite fauna of large whales but also to provide new insights in current available methods for gathering parasitological data by using non- or minimally invasive sampling techniques. We focus on methods, which will allow detailed parasitological studies to gain a broader knowledge on parasitoses affecting wild, free-swimming large whale populations.

Nuevos restos de Scaldicetus (Cetacea, Odontoceti, Physeteridae) del Mioceno superior, sector occidental de la Cuenca del Guadalquivir (sur de España)
Universidad Nacional Autónoma de México: Centro de Geociencias, 2013Co-Authors: Toscano Grande Antonio, Abad De Los Santos, Manuel, Ruiz Muñoz Francisco, Muñiz Guinea Fernando, Álvarez García Genaro, Mara García, Edith Xio, Caro Gómez, José AntonioAbstract:The Physeteridae family is one of the basal branches in odontocete cetaceans. At the present, it is only represented by three species belonging to the genus Physeter and Kogia, although it includes numerous extinct genera as Scaldicetus. From a systematic point of view, Scaldicetus is one of the most common and problematic group of the extinct subfamily Hoplocetinae during the Neogene. It is considered a polyphyletic genus and its taxonomic use has been relegated to the identification of isolated teeth. Two dental pieces identified as Scaldicetus found in two late Miocene units of the western sector of the Guadalquivir Basin (south of Spain) have been analyzed in this work. The sedimentological and palaeontological analysis of the facies indicates littoral to open marine environments with profuse potential preys for Scaldicetus. The morphological characteristics and the heterogeneous palaeobiogeographic and ecological distribution of Scaldicetus denote that this taxon occupied an ecological niche similar to that of Orcinus orca at present. This paper constitutes the first systematic review of Odontocetes fossils in Southern Spain and contributes new data about the understanding of this controversial genus.La familia Physeteridae constituye una rama basal dentro de los cetáceos odontocetos. En la actualidad solo está representada por tres especies pertenecientes a los géneros Physeter y Kogia, aunque incluye numerosos géneros extintos. Scaldicetus es uno de los géneros neógenos más comunes y problemáticos desde el punto de vista taxonómico de la extinta subfamilia Hoplocetinae. Considerado un género polifilético, su uso sistemático ha quedado relegado a piezas dentales aisladas. En este trabajo se analizan dos piezas dentales atribuidas al género Scaldicetus halladas en dos formaciones del Mioceno superior de la región occidental de la Cuenca del Guadalquivir (sur de España). Los análisis sedimentológico y paleontológico de las facies indican ambientes litorales y marinos profundos, con abundantes presas potenciales para Scaldicetus. Sus características morfológicas y su distribución ecológica y paleobiogeográfica, indican que Scaldicetus ocupó un nicho ecológico similar al de Orcinus orca en la actualidad. Esta aportación constituye la primera revisión sistemática de restos fósiles de odontocetos en el sur de España, e intenta aportar información que contribuya a la comprensión de este controvertido género
