Diagnosis of tuberculosis in ruminants and camelids: optimization of cell-based and humoral tests

Carmen Casal Comendador defended the PhD Thesis at the Faculty of Veterinary Medicine of the Complutense University of Madrid

Tuberculosis is a bacterial zoonosis that represents an important health problem in humans, domestic animals and wildlife. The most frequently involved species in animal tuberculosis are Mycobacterium bovis and M. caprae. The disease has a major economic impact caused by the decreased production in animals, the commercial restrictions implied, and the costs of eradication campaigns in cattle. In the last years, tuberculosis is gaining relevance in other domestic species i.e. goats, mainly in those countries with a high census of this species. Additionally, tuberculosis in South American cameli… Read more

Virological and Epidemiological analysis of Colony Collapse Disorder in Spain. Study of causes and consequences

PhD Thesis defense by Marina Vicente Rubiano at the Faculty of Veterinary Medicine of the Complutense University of Madrid

The honey bee Apis mellifera is the main pollinator species used to increase the productivity of crops and it also has a central role in the conservation of the worldwide diversity. In the last decades, an increase in the mortality of honey bee colonies has been observed in many regions, causing a great alarm due to its potential economic and environmental consequences. This phenomenon, which has unknown causes, has been called “Colony Collapse Disorder” (CCD) when a depopulation of adult honey bees is observed, or “winter losses” when colonies do not survive to the winter by unidentified caus… Read more

Resistance to cephalosporins in Enterococcus spp.

Laura Carrilero Aguado defended the PhD Thesis at the Faculty of Veterinary Medicine of the Complutense University of Madrid

Enterococcus spp. are facultatively anaerobic, catalase-negative Gram-positive cocci, arranged individually, in pairs, or short chains. Enterococci include one of the most important nosocomial pathogens, Enterococcus faecalis. E. faecalis can be responsible for infections of wounds, soft tissue and the urinary tract. In some cases they produce bacteremia which can lead to endocarditis in previously damaged cardiac valves. Several factors have been identified as important in the pathogenesis of the bacteria. Nevertheless, it remains unclear how this commensal bacteria evolved into an insidious … Read more

Salmonella enterica Serovar Typhimurium Exploits Inflammation to Modify Swine Intestinal Microbiota

Frontiers in cellular and infection microbiology publish this investigation article

Salmonella enterica serovar Typhimurium is an important zoonotic gastrointestinal pathogen responsible for foodborne disease worldwide. It is a successful enteric pathogen because it has developed virulence strategies allowing it to survive in a highly inflamed intestinal environment exploiting inflammation to overcome colonization resistance provided by intestinal microbiota. In this study, we used piglets featuring an intact microbiota, which naturally develop gastroenteritis, as model for salmonellosis. We compared the effects on the intestinal microbiota induced by a wild type and an atten… Read more

The role of Leishmania immune adherence reaction in human infection

PhD Thesis defense by Dario Cabañes Rodríguez at the Faculty of Veterinary Medicine of the Complutense University of Madrid

The leishmanioses are vector-borne diseases caused by trypanosomatid protozoa of the genus Leishmania. This parasite has a heteroxenous life cycle, living as extracellular flagellated promastigote in the digestive tract of the insect vector and as obligate intracellular sessile amastigote within mononuclear phagocytes of vertebrate hosts. Leishmania is transmitted to susceptible hosts through the bite of infected sandflies of the genus Phlebotomus. Phlebotomine sandflies are telmophage diptera that feed from hematomas; infected females inoculate promastigotes into hematomas in host skin whil… Read more

Evidence of shared bovine viral diarrhea infections between red deer and extensively raised cattle in south-central Spain

Investigation article published in BMC Veterinary Research

Bovine viral diarrhea virus (BVDV) is a pestivirus that affects cattle production worldwide and that can infect other ungulates such as cervids and even wild boar (Sus scrofa). It is believed that domestic livestock can become infected through contact with wild animals, though it is known that infection can spread among wild animals in the absence of contact with livestock. Little is known about the sharing of BVDV infection between wild and domestic animals in the same habitat, which is important for designing eradication campaigns and preventing outbreaks, especially on hunting estates with … Read more

Fluorescent microbead-based immunoassay for anti-Erysipelothrix rhusiopathiae antibody detection in cetaceans

Investigation published in Diseases of Aquatic Organisms

A fluorescent microbead-based immunoassay (FMIA) for detection of anti-Erysipelothrix rhusiopathiae antibodies in pigs was adapted to cetaceans. The FMIA was validated and adjusted using serum samples from 10 vaccinated captive bottlenose dolphins Tursiops truncatus collected between 1 and 13 mo after immunization. The technique was then used to analyze specimens from 15 free-ranging cetaceans stranded alive in the Valencian Mediterranean coast between 2006 and 2014, which comprised 11 striped dolphins Stenella coeruleoalba, three Risso’s dolphins Grampus griseus and one bottlenose dolphin Tur… Read more

African swine fever virus transmission cycles in Central Europe: Evaluation of wild boar-soft tick contacts through detection of antibodies against Ornithodoros erraticus saliva antigen

BMC Veterinary Research publish this investigation article

BACKGROUND: African swine fever (ASF) is one of the most complex viral diseases affecting both domestic and wild pigs. It is caused by ASF virus (ASFV), the only DNA virus which can be efficiently transmitted by an arthropod vector, soft ticks of the genus Ornithodoros. These ticks can be part of ASFV-transmission cycles, and in Europe, O. erraticus was shown to be responsible for long-term maintenance of ASFV in Spain and Portugal. In 2014, the disease has been reintroduced into the European Union, affecting domestic pigs and, importantly, also the Eurasian wild boar population. In a first a… Read more

Genetic analysis of human clinical isolates of Lactococcus garvieae: relatedness with isolates from foods

Investigation article published in Infection Genetics and Evolution

Lactococcus garvieae is a gram-positive bacterium well-known as an important pathogen in aquaculture, and it is also a human pathogen of increasing clinical significance. Forty-three human L. garvieae isolates from clinical specimens were characterized by Multilocus Sequence Typing (MLST). Twenty-six different sequence types (STs) were identified among the human isolates, of which 20 were novel STs. Most human isolates clustered into four clonal complexes, with a predominance of CC3. Within CC3, ST10 was the most common genotype, indicating the existence of a circulating genetic lineage among … Read more

Streptococcus caprae sp. nov., isolated from a Iberian Ibex (Capra pyrenaica hispanica)

Investigation article published in International Journal of Systematic and Evolutionary Microbiology

Biochemical and molecular genetic studies were performed on a novel Gram-positive catalase-negative coccus-shaped organism isolated from tonsil samples of two Spanish Ibex. The microorganism was identified as a streptococcal species based on its cellular morphological and biochemical tests. 16S rRNA gene sequence comparison studies confirmed its identification as a member of the genus Streptococcus, but the organism did not correspond to any species of this genus. The nearest phylogenetic relative of the unknown coccus from ibex was Streptococcus porci (96.6% 16S rRNA gene sequence similarity)… Read more

Environmental Assessment of Tetracycline’s Residues Detected in Pig Slurry and Poultry Manure

Journal of Environmental Protection publish this article

The widespread use of antimicrobials in animal husbandry has led to an increase in concentrations of antibiotics in animal faeces. Furthermore, the spreading of this waste as fertilizer on agricultural land indirectly introduces antimicrobial residues into the environment. This study examined samples of pig slurry and poultry manure for three tetracyclines—oxytetracycline (OTC), chlortetracycline (CTC) and doxycycline (DOC) and conducted an environmental evaluation of soils. The samples were taken from manure heaps on eight broiler chicken farms and from slurry ponds on eight pig farms. The te… Read more

Sea mammal morbilliviruses

Chapter included in Mononegaviruses of veterinary importance. Volume 2: molecular epidemiology and control edited by CABI

Cetacean morbillivirus (CeMV) has caused thousands of deaths in cetaceans worldwide. The first known outbreak happened in 1988 on the USA`s Atlantic coast. Since then, different outbreaks have affected cetacean populations in the northern hemisphere, especially in the Mediterranean and on the Atlantic coast of the USA. Three strains of CeMV have been recognized officially: dolphin morbillivirus, porpoise morbillivirus and pilot whale morbillivirus. However, recently there have been reports of CeMV infections in the Pacific and southern hemisphere, where the obtained sequences seem to be new st… Read more

Mejor uso posible de los antibióticos en ganadería

Revista Producción Animal publish this article

Los antibióticos son medicamentos singulares, ya que no sólo combaten a las bacterias patógenas que se encuentran en el sitio de infección, sino que además actúan también sobre todas las bacterias que encuentran durante su travesía por el organismo del individuo afectado, lo que facilita la selección de las que porten algún mecanismo de resistencia y su transmisión a otros individuos que, cuando enfermen, no podrán ser tratados. El mejor uso posible de los antibióticos busca por tanto maximizar el efecto terapéutico y minimizar el desarrollo de resistencias. Los antibióticos son armas terapéu… Read more

A European perspective on the transmission of food-borne pathogens at the wildlife-livestock-human interface

The book Food Safety Risks from wildlife: Challenges in Agriculture, Conservation and Public Health edited by Springer International Publishing includes this chapter

There are many unique aspects and peculiarities regarding the transmission of foodborne pathogens at the wildlife–livestock–human interface in Europe, which include the diversity of farming systems, wildlife and habitats, as well as the consumption habits of the European human population. However, it can be generalized that zoonotic diseases acquired from wildlife (or directly related to wildlife) are mainly linked to the consumption of undercooked venison, hunting or handling infected game carcasses. Hunting has always been an integral part of the cultures and traditions of European rural soc… Read more
