Multi-Etiological Nature of Tuberculosis-Like Lesions in Condemned Pigs at the Slaughterhouse
Investigation published in PLoS ONE
Tuberculosis-like lesions (TBL) in pigs have been associated with microorganisms other than mycobacteria. In this work a histopathological and microbiological evaluation of TBL in pigs is shown. A total of 352 samples belonging to 171 pigs totally condemned at slaughterhouse due to generalized TBL were sampled and selected for analysis. Pyogranulomatous (56.2%) and granulomatous lesions (20.2%) were observed in all analysed organs. Most of the granulomas observed in both lymph nodes and lungs belonged to more advanced stages of development (stages III and IV) whereas in the liver and the splee…

Equine Strangles
VISAVET Outreach Journal publish this article
Streptococcus equi (S. equi) is the bacterium that causes equine strangles. Some horses are carriers of S. equi, meaning that they are infected with S. equi but do not show any signs of the disease. These horses can be a source of S. equi for other (susceptible) horses. Young horses (weaning foals, yearlings and two-year-old horses) are particularly susceptible to this disease; however, strangles can affect horses of any age.…

Salmonella Typhimurium exploits inflammation to its own advantage in piglets
Frontiers in Microbiology publish this investigation article
Salmonella Typhimurium (S. Typhimurium) is responsible for foodborne zoonotic infections that, in humans, induce self-limiting gastroenteritis. The aim of this study was to evaluate whether the wild-type strain S. Typhimurium (STM14028) is able to exploit inflammation fostering an active infection. Due to the similarity between human and porcine diseases induced by S. Typhimurium, we used piglets as a model for salmonellosis and gastrointestinal research. This study showed that STM14028 is able to efficiently colonize in vitro porcine mono-macrophages and intestinal columnar epithelial (IPEC-J…

Efecto de los subproductos del aceite de oliva en cerdos infectados por Salmonella Choleraesuis
Juan Ángel Díez Rodríguez defended this presentation at the Faculty of Veterinary Medicine of the Complutense University of Madrid in order to obtain the Master of Research
La salmonelosis es la segunda enfermedad de transmisión alimentaria de origen animal más importante en la Unión Europea. La serovariedad más importante en el cerdo es S. Choleraesuis, que causa una enfermedad septicémica y sistémica en los animales. Dado el actual problema con la resistencia a antimicrobianos, es vital desarrollar nuevas estrategias que consigan disminuir la diseminación de resistencias antimicrobianas entre bacterias. Un producto alternativo al uso de antimicrobianos podría ser la utilización de los subproductos derivados de la producción del aceite de oliva, por su alto cont…

Identificación de garrapatas recogidas en hospedadores animales y medio ambiente de la Comunidad de Madrid y Cataluña y determinación de la prevalencia de Rickettsia spp. en las mismas
Degree thesis defended by Clara Colmenero de Miguel at the Faculty of Veterinary Medicine of the Complutense University of Madrid
En la actualidad hay descritas más de 900 especies de garrapatas, de las cuales dos tercios son ixódidos, conocidas comúnmente como garrapatas duras. Su importancia en Salud Pública radica en que pueden actuar como vectores de enfermedades infecciosas, muchas de ellas de carácter zoonósico, como las rickettsiosis. De hecho, las garrapatas son los arácnidos que más enfermedades transmiten después de los mosquitos.
Además, en los últimos años se ha observado un aumento considerable en el número de enfermedades transmitidas por estas, lo cual se debe a los cambios en los hábitos de vida del h…

Collection of samples in horses using a nasopharyngeal swab
VISAVET Outreach Journal published this online article
The collection of samples using a nasopharyngeal swab is necessary in the majority of horses presenting with respiratory or neurological signs, for the diagnosis of bacterial (e.g. Streptococcus equi subsp. equi, Rhodococcus equi, etc.) and viral (e.g. Equine Herpesvirus type 1/type 4, Equine Arteritis virus, West Nile virus, etc.) agents. It is essential that the collection of samples is done correctly and also that the right swabs are used, in order to avoid false negatives in the diagnosis.…

Fatal Erysipelothrix rhusiopathiae septicemia in two Atlantic dolphins (Stenella frontalis and Tursiops truncatus)
Diseases of Aquatic Organisms publish this investigation article
We describe gross, histopathologic, ultrastructural, immunohistochemical, and microbiologic features of acute septicemia by Erysipelothrix rhusiopathiae in an Atlantic spotted dolphin Stenella frontalis and an Atlantic bottlenose dolphin Tursiops truncatus. Generalized lymphadenomegaly and widespread hemorrhages were the most consistent macroscopic findings. Tricavitary effusion and icterus were noted in one individual. Histologically, all organs examined showed numerous variably sized bacillary bacterial emboli (Gram-positive; Ziehl-Neelsen-negative), typically associated with systemic conges…

Identificación y caracterización de Aeromonas spp. aisladas de peces enfermos
Presentation by Irene Cerdá Lentijo to obtain the Master of Microbiology. Autonomous University of Madrid
El género Aeromonas se ha clasificado tradicionalmente en dos categorías: grupo mesófilo o grupo A. hydrophila, y grupo psicrófilo o A. salmonicida, si bien hoy en día se conocen más de treinta especies. A pesar de formar parte de la microbiota normal de diversas especies animales, algunos miembros de este género pueden comportarse como patógenos animales, como los peces (siendo agentes causales de furunculosis o de eritrodermatitis de la carpa, entre otras), lo cual tiene un importante impacto en la industria acuícola, ocasionando grandes pérdidas económicas además de tener gran importancia s…

Thermal reference points as an index for monitoring body temperature in marine mammals
Investigation published in BMC Research Notes
BACKGROUND:
Monitoring body temperature is essential in veterinary care as minor variations may indicate dysfunction. Rectal temperature is widely used as a proxy for body temperature, but measuring it requires special equipment, training or restraining, and it potentially stresses animals. Infrared thermography is an alternative that reduces handling stress, is safer for technicians and works well for untrained animals. This study analysed thermal reference points in five marine mammal species: bottlenose dolphin (Tursiops truncatus); beluga whale (Delphinapterus leucas); Patagonian sea lion…

Use of colistin-containing products within the European Union and European Economic Area (EU/EEA): development of resistance in animals and possible impact on human and animal health
Investigation published in International Journal of Antimicrobial Agents
Since its introduction in the 1950s, colistin has been used mainly as a topical treatment in human medicine owing to its toxicity when given systemically. Sixty years later, colistin is being used as a last-resort drug to treat infections caused by multidrug-resistant (MDR) Pseudomonas aeruginosa, Acinetobacter baumannii and Enterobacteriaceae (e.g., Escherichia coli, Klebsiella pneumoniae), for which mortality can be high. In veterinary medicine, colistin has been used for decades for the treatment and prevention of infectious diseases. Colistin has been administered frequently as a group tre…

Effect of the inoculation site of bovine purified protein derivative (PPD) on the skin fold thickness increase in cattle from officially tuberculosis free and tuberculosis-infected herds
Investigation article published in Preventive Veterinary Medicine
The official technique for diagnosis of bovine tuberculosis (bTB) worldwide is the tuberculin skin test, based on the evaluation of the skin thickness increase after the intradermal inoculation of a purified protein derivative (PPD) in cattle. A number of studies performed on experimentally infected or sensitized cattle have suggested that the relative sensitivity of the cervical test (performed in the neck) may vary depending on the exact location in which the PPD is injected. However, quantitative evidence on the variation of the test accuracy associated to changes in the site of inoculation…

Testing Eurasian wild boar piglets for serum antibodies against Mycobacterium bovis
Preventive Veterinary Medicine publish this investigation article
Animal tuberculosis (TB) caused by infection with Mycobacterium bovis and closely related members of the M. tuberculosis complex (MTC), is often reported in the Eurasian wild boar (Sus scrofa). Tests detecting antibodies against MTC antigens are valuable tools for TB monitoring and control in suids. However, only limited knowledge exists on serology test performance in 2-6 month-old piglets. In this age-class, recent infections might cause lower antibody levels and lower test sensitivity. We examined 126 wild boar piglets from a TB-endemic site using 6 antibody detection tests in order to asse…

Streptococcus pharyngis sp. nov., a new streptococcal species isolated from the respiratory tract of wild rabbits
Investigation published in International Journal of Systematic and Evolutionary Microbiology
Four isolates of an unknown Gram-positive, catalase-negative coccus-shaped organism isolated from pharynx of four wild rabbits, were characterized by phenotypic and molecular genetic methods. The microorganisms were tentatively assigned to the genus Streptococcus based on their cellular morphological and biochemical criteria, although the organisms did not appear to correspond to any recognized species. Comparative 16S rRNA gene sequencing confirmed their identification as members of the genus Streptococcus, being phylogenetically closet related to Streptococcus porcorum 682-03T (96.9 % 16S rR…
