Macroscopic and microscopic lesions in passerine birds caused by plasmodium spp., leucocytozoon spp. and haemoproteus spp
Degree Final Project defended by Gonzalo Anibarro García-Baquero
The order Passeriformes, known as `passerines`, is a large and diverse order of birds that groups some 6,500 species, which are of great importance at an ecological and public health level. It currently faces numerous threats, both natural and human, that endanger the survival of its populations. Among these threats, parasites of the order Haemosporida occupy a relevant place. This work focuses on knowing the incidence of Haemosporida parasites in the population of passerine birds and describing the macroscopic and histological lesions they cause in order to understand and deepen in their path…

Novel Epidemiologic Features of High Pathogenicity Avian Influenza Virus A H5N1 2.3.3.4b Panzootic: A Review
Investigation article published in Transboundary and Emerging Diseases
Avian influenza is one of the most devastating avian diseases. The current high pathogenicity avian influenza (HPAI) A virus H5N1 clade 2.3.4.4b epizootic began in the 2020–2021 season, and has caused a panzootic, considered one of the worst ever reported. The present panzootic has novel epidemiological features that represent a challenge for its prevention and control. This review examines key epidemiological changes of the disease such as seasonality, geographic spread, and host range. The seasonality of the virus has changed, and contrary to previous avian influenza epizootics, this subclad…

Stream of revelation: detection of equine herpesvirus-1 (EHV-1) in urine during myeloencephalopathy outbreaks
Investigation published in Equine veterinary journal
Background: The detection of EHV-1 by real-time PCR in nasal swabs (NS), whole blood, brain, and spinal cord samples has been extensively described. However, there remains a notable gap in understanding the excretion of the virus in urine, the patterns of DNA detection, and the potential role of urine in viral dissemination during an outbreak.
Objectives: To ascertain the presence of EHV-1 DNA in urine during natural infection and to compare the DNA detection patterns of EHV-1 in urine, buffy coat (BC), and NS.
Study design: Prospective clinical study.
Methods: During the hospitalisat…

MicroMundo: Bridging Citizen Science and Service-Learning to promote Antibiotic Resistance Awareness in the Community
Oral communication in 7th European Conference on Service-Learning in Higher Education
The threat of antimicrobial resistance has been set by the World Health Organization into its priorities for immediate action (WHO, 2014). Antibiotics are our therapeutic arsenal against infectious diseases, saving millions of lives every year worldwide. However, a misuse of these valuable drugs in environmental, animal and human health over the last decades has led to the expansion of multi-resistant bacteria, responsible for over 1.000.000 deaths yearly. As prominent keys to fight antibiotic resistance stand: (i) to promote awareness of the problem in the population, leading to a rational an…

Genomic comparison between Mycobacterium bovis and Mycobacterium microti and in silico analysis of peptide-based biomarkers for serodiagnosis
Investigation article published in Frontiers in veterinary science
In recent years, there has been an increase in the number of reported cases of Mycobacterium microti infection in various animals, which can interfere with the ante-mortem diagnosis of animal tuberculosis caused by Mycobacterium bovis. In this study, whole genome sequencing (WGS) was used to search for protein-coding genes to distinguish M. microti from M. bovis. In addition, the population structure of the available M. microti genomic WGS datasets is described, including three novel Belgian isolates from infections in alpacas. Candidate genes were identified by examining the presence of the r…

Diagnosis of leishmaniasis in wild murine fauna in Spain
Degree Final Project defended by Paloma Alonso Collado
Leishmaniasis is a zoonotic parasitic disease caused by protozoa of the genus Leishmania, which is primarily transmitted by dipteran vectors (phlebotomine sandflies). It is a disease that affects a large part of the countries worldwide, including Spain, where it is considered endemic.
The outbreaks that have occurred in the Community of Madrid since 2009 due to infected leporids have brought wild reservoirs into focus. The diagnosis of the disease canpor be made by direct observation of amastigotes in areas of active multiplication, immunological diagnosis or molecular diagnosis.
The aim…

Study of the Toscana virus in lagomorphs
Sara Martín-Gromaz Esteban defended this Degree Final Project
The Toscana Virus (TOSV) is an arbovirus of the genus Phlebovirus, which is transmitted by the bite of phlebotomine sandflies of the genus Phlebotomus and is currently considered an emerging zoonotic pathogen. This virus is known to cause meningitis in humans in endemic areas of the Mediterranean, especially during the summer months when there is increased phlebotomine sandfly activity. Recent studies suggest that some mammals, including lagomorphs, could act as reservoirs or potential amplifying hosts of the virus in certain regions.
In addition, co-infection with Leishmania, which is transm…

Detection of Leishmania in rabbit ticks (Oryctolagus cuniculus)
Degree Final Project defended by Mª Leticia del Barrio Montañés
The study focused on the detection of Leishmania infantum in ticks collected from wild rabbits (Oryctolagus cuniculus) in the Community of Madrid. Leishmaniasis is a zoonotic disease transmitted by sandflies, and its control is critical due to its global spread and the lack of a vaccine for humans. The primary reservoir is the dog, but the outbreak in Madrid (2009-2012) evidenced hares and rabbits as competent reservoirs, suggesting the need to explore this disease further, for example, by examining other potential common vectors in these wild rabbits, such as ticks.
The main objective was to…

Tuberculosis outbreak in cattle in Rogaland, Noeway
The outbreak of tuberculosis in cattle in Rogaland in 2022 highlights the importance of veterinarians having up-to-date knowledge of these types of “neglected” infectious agents and the diseases they cause. Mycobacterium bovis is part of the Mycobacterium tuberculosis (MTB) complex along with several other mycobacterial species, all of which are slow-growing and primarily pathogenic for humans, cattle, and small rodents. M. bovis and other species within the MTB complex are facultatively intracellular pathogens, and their pathogenicity is associated with the bacteria’s ability to infect a host…
