ALFONSO X EL SABIO UNIVERSITY
PARASITIC DISEASES AND PARASITOLOGY
I started my researching activity as a Veterinary student in the Veterinary Faculty of Complutense University of Madrid, in the Parasitology field of the Animal Health Department. From the beginning of my work as a researcher I have taken part in different researching projects related to vectorial diseases in Veterinary Medicine. These investigations were not only based on the illnesses the parasites can cause in animals. They also included important information and data about different field of knowlegde related to the artrhropods responsible for the transmission of the mentioned illnesses. In fact, my development as a researcher involves different fields of study in which arthropods are present. My doctoral thesis was titled “Equine anoplocefalosis: epidemiology of the infection in Spain and a study of the lesions caused by Anoplocephala perfoliata (Goeze, 1782). For this thesis I had to study in depth oribatid mites, which are the intermediate host of anoplocephalids. One of the first things I learned was how to identify them by different morphological features. Moreover, different laboratorial techniques were developed to collect and preserve them in the laboratory in order to carry out experimental infections and be able to study horse infections and clinical consequences. As a part of the horse infection´s research, molecular techniques such as PCR and multiplex PCR were performed in oribatid mites. The arthropod´s identification accomplished during my doctoral thesis involved me in this field of knowledge and started my ticks formation. At the beginning, I was mainly focused on their identification by using specific keys and, after that, as a part of different researching projects, I also focused on looking for pathogens transmitted by these ticks. One of these investigations was related to seroprevalence of piroplasmosis in Spanish horses. The results of these investigations involve: divulgative and scientific articles and several participations in congresses described in detail in the curriculum vitae. As a part of my constant training I have done several stays in research, diagnosis and innovation centers. One of my stays took place in the Veterinary Faculty of León, a university in which I have also been involved as an associate in different projects during 5 years. Moreover, I have also participated in other researching projects of the Veterinary Faculty of Madrid and the Veterinary Faculty of the National University of the Littoral in Esperanza, Argentina. On another hand, I have collaborated with the beekeeping and agrienvironmental research center of Marchamalo (Guadalajara) and from 2019 to 2022 I have collaborated as a researcher in the Parasitology Area of the Carlos III Health Institute, in a project titled “Celular and molecular approaches to studying the asexual life cycle of the intraerythrocytic parasite Babesia divergens, the main causative agent of bovine and human babesiosis in Europe”. Currently I am working on some research projects with PhD Félix Valcárcel and his team, at INIA Animal Reproduction Department, Animal Parasitology Department Since 2005, I work at Alfonso X El Sabio University in the Veterinary Faculty. I am a teacher of the subjects Parasitology and Parasitic diseases and in 2011 and up till now, I became the coordinator of Parasitic Diseases. Since 2010, I am also responsible for carrying on selective control in livestock farms from Segovia and Madrid. This work has allowed and allows me to diagnose the presence of vector borne diseases transmitted by arthropods, including the diseases transmitted by Ixodid ticks, very present in production and companion animals. As a part of my work in the area of clinical diagnosis, I have been able to develop a few investigations in vector borne diseases in small animals that have resulted in 7 final degree projects in the last 5 years. As head researcher, I have directed three projects at the Alfonso X el Sabio University. In the last one, devoted to the diagnosis applied to research in Veterinary Sciences, among other activities, a research has been conducted based on the study of hard ticks species present in the National Park of Tapada in Mafra, Portugal. We are currently developing two different projects based on ticks of Tapada National Park and on the ticks of the environment and animals of Segovia.

Abstract

Introduction

Hard ticks can easily spread and colonise novel regions. However, some factors such as habitat, climatic conditions, or available hosts determine the distribution and abundance of ticks. The main objectives of this study were to identify the hard tick species present in fallow deer and red deer in Tapada Nacional Park (Mafra, Portugal).

Methods

Ticks from red deer (n=14) and fallow deer (n= 71) were manually collected in Tapada, from 2012 to 2019.Ticks were kept in 70% ethanol and carried out to the laboratory to be identified using morphological keys.

Results

A total of 596 tick, adults, were collected from cervids; 193 males and 403 females. Ixodes ricinus (73.15%) was the most prevalent tick both in fallow and red deer, followed by Riphicephalus sanguineus (11.4%), Hyalomma impeltatum (4.19%), H. detritum detritum and H. punctata (2.35%), D. marginatus (1.17%), H. sulcata (1.01), H. lusitanicum (0.84%) and I. hexagonus (0.3%). 3.19% of ticks were only identified to genus level as Hyalomma sp. The mean number of ticks per animal was similar in fallow deer and in red deer (7.2 and 5.9).

Conclusions

The high incidence of I. ricinus is probably due to the climatic conditions of Tapada National Park (warm temperate, moist forest climate, with wet winters, dry summers) and host availability. The presence of R. sanguineus was higher than expected although it can be explained by a high presence of canids in the park. Finally, the unexpected presence of several Hyalomma species could be due to the ability of ticks to adapt to different environmental conditions.
