Hemolysis, icterus and lipemia interfere with the determination of two oxidative stress biomarkers in canine serum

BMC Veterinary Research publish this investigation article

Background: Oxidative stress has been proven to play a role in numerous human and canine diseases. Among the biomarkers of oxidative stress, Thiobarbituric Acid Reactive Substances (TBARS) and Total Antioxidant Status (TAS) are two of the most widely used. Preanalytical factors are crucial for obtaining accurate results in these assays. Hemolysis, icterus and lipemia (HIL) are common sources of preanalytical errors in the laboratory; however, limited information is available regarding the considerations for canine specimens. Therefore, the objective of this study was to evaluate the potential … Read more

Will we ever eradicate animal tuberculosis?

Investigation article published in Irish veterinary journal

Two characteristics of the Mycobacterium tuberculosis complex (MTC) are particularly relevant for tuberculosis (TB) epidemiology and control, namely the ability of this group of pathogens to survive in the environment and thereby facilitate indirect transmission via water or feed, and the capacity to infect multiple host species including human beings, cattle, wildlife, and domestic animals other than cattle. As a consequence, rather than keeping the focus on certain animal species regarded as maintenance hosts, we postulate that it is time to think of complex and dynamic multi-host MTC mainte… Read more

Primary Feline Tauopathy: Clinical, Morphological, Immunohistochemical, and Genetic Studies

Investigation published in Animals

Tauopathies are a group of neurodegenerative diseases characterized by the pathological aggregation of hyperphosphorylated tau in neurons and glia. Primary tauopathies are not uncommon in humans but exceptional in other species. We evaluate the clinical, neuropathological, and genetic alterations related to tau pathology in 16 cats aged from 1 to 21 years with different clinical backgrounds. Interestingly, a 10-year-old female cat presented a six-year progressive history of mental status and gait abnormalities. The imaging study revealed generalized cortical atrophy. Due to the poor prognosis,… Read more

Persistence of equine herpesvirus type 1 in urine

Abel Dorrego Rodríguez defended this presentation at the Faculty of Veterinary Medicine of the Complutense University of Madrid in order to obtain the Master of Research

Equine herpesvirus type 1 is a highly contagious virus distributed globally that causes respiratory, reproductive, and neurological disease in horses. It often presents itself in the form of outbreaks where rapid diagnosis is essential. The description of the virus`s presence in urine opens the door to its use as a diagnostic sample. This study was conducted in order to understand the behaviour of the virus in this fluid and to establish the most suitable preservation method. The virus was artificially inoculated into samples from 6 horses, assessing how the concentration varied over time and… Read more

Evaluation of diagnostic tests for the detection of tuberculosis in cervids

Mónica Alonso Fernández defended this Degree Final Project

Tuberculosis is one of the infectious diseases with the greatest impact worldwide, caused by bacteria of the Mycobacterium tuberculosis complex, capable of affecting both humans and animals. The first actions to establish control of bovine tuberculosis in Spain started in the middle of the 20th century, which has led to a decrease in the incidence and prevalence in animals. Wildlife is an important reservoir for domestic cattle, which makes eradication difficult. Cervids are one of the main reservoirs of tuberculosis for cattle, especially red deer (Cervus elaphus) and fallow deer (Dama dama).… Read more

Surveillance of zoonotic pathogens in wild birds in the Community of Madrid

Daniel Peromingo Fernández defended this Degree Final Project

Wild birds are important reservoirs of zoonotic pathogens, although the risk of transmission to humans is quantitatively lower than for other mammalian host groups, due to their phylogenetic distance. The main epidemiological determinants of wild birds in relation to zoonoses include migratory movements and their association with emerging and re-emerging diseases, and their ability to adapt to urban environments, which is associated with increased exposure to humans. Both psittacosis and West Nile fever are zoonoses of great public health relevance and share their reservoir in birds. The aim o… Read more

Detection of equine herpesvirus-1 (EHV-1) in urine samples during outbreaks of equine herpesvirus myeloencephalopathy

Equine veterinary journal publish this investigation article

Background: Real-time PCR is the diagnostic technique of choice for the diagnosis and control of equine herpesvirus-1 (EHV-1) in an outbreak setting. The presence of EHV-1 in nasal swabs (NS), whole blood, brain and spinal cord samples has been extensively described; however, there are no reports on the excretion of EHV-1 in urine, its DNA detection patterns, and the role of urine in viral spread during an outbreak. Objectives: To determine 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 de… Read more

New approaches in the control of infectious fertility problems in extensive cattle

PhD Thesis defense by Coral Polo Vaquero at the VISAVET Centre of the Complutense University of Madrid

In Spain, extensive cattle farming is a sector characterized by its priority orientation towards beef production and whose main objective from a productive point of view is to maximize the number of calves per cow and year. Extensive exploitation systems may be able to use the natural resources of the environment, contributing to the maintenance of resilient ecosystems as long as they are properly managed. In 2020, Spain generated the 24 % of beef within the European Union (EU), being the third main beef producing country. However, the average annual fertility rates of this sector in Spain is … Read more

Epidemiological impacts of attenuated African swine fever virus circulating in wild boar populations

Research in Veterinary Science publish this investigation article

African swine fever virus (ASFV) genotype II has been present in wild boar in the European Union since 2014. Control measures have reduced the incidence of the ASF, but highly virulent as well as attenuated ASFV strains continue to circulate. We present the intraherd epidemiological parameters of low and highly virulent ASFV in wild boar from experimental data, and for the first time, evaluate the impact of attenuated strain circulation through unique deterministic compartmental model simulations under various potential scenarios and hypotheses. Using an estimated PCR infectious threshold of T… Read more

Oral immunization with heat-inactivated Mycobacterium bovis reduces local parasite dissemination and hepatic granuloma development in mice infected with Leishmania amazonensis

Investigation published in Research in Veterinary Science

Aiming to explore whether oral immunization with heat-inactivated Mycobacterium bovis (HIMB) protects mice against Leishmania infection, 18 female BALB/c mice were randomly assigned to the immunized group, that received oral HIMB, or the control group, and were infected by inoculation of 10,000 Leishmania amazonensis promastigotes in the footpad. Spleen culture was positive in 55.55% of immunized mice and in 100% of control mice (p = 0.082). The number of immunolabeled amastigotes number in the popliteal lymph node was lower in the immunized group (p = 0.009). The immunized group presented few… Read more
