    Elaboración de una guía online de antifúngicos y resistencias antifúngicas en Veterinaria
    (2022) Álvarez Pérez, Sergio; Anega de Alvarado, Blanca; Tercero Guerrero, Daniela Vanessa; García Sánchez, Marta Eulalia; Blanco Cancelo, José Luis
    La rápida aparición a nivel mundial de resistencias a los fármacos antifúngicos representa una gran amenaza para la salud humana y animal, así como para la seguridad alimentaria. Sin embargo, existe aún muy poca conciencia pública sobre la relevancia de la resistencia a los antifúngicos en medicina veterinaria, lo cual contrasta con el gran interés que despiertan las bacterias resistentes a antibióticos. Entre los principales factores responsables del menor interés por el estudio de las resistencias antifúngicas en medicina animal suele destacarse la escasa importancia que se concede en veterinaria a los procesos infecciosos de etiología fúngica. Mediante el presente Proyecto de Innovación Educativa nos propusimos crear una “Guía Online de Antifúngicos y Resistencias Antifúngicas en Veterinaria” de acceso gratuito y 100% online, que incluya información relevante y material gráfico sobre los antifúngicos utilizados actualmente en medicina veterinaria, las técnicas aplicadas al estudio de los perfiles de sensibilidad antifúngica y los principales mecanismos de resistencia antifúngica observados en aislamientos de hongos filamentosos y levaduras de origen animal. Se pretende así que los estudiantes del Grado en Veterinaria, del Diploma en Asistencia Técnica en Clínica Veterinaria y otras titulaciones afines vayan adquiriendo conocimientos sobre Micología Clínica que les serán de gran utilidad durante sus estudios y, posteriormente, en su acceso a la vida profesional en un contexto de escasez de expertos en Micología Veterinaria.

    Creación de un Atlas online de Micología Clínica Veterinaria
    (2021-06-11) García Sánchez, Marta Eulalia; Anega de Alvarado, Blanca; Álvarez Pérez, Sergio; Blanco Cancelo, José Luis
    Pese a la creciente importancia de los hongos en patología animal, la información existente sobre la prevalencia de la mayoría de micosis animales es aún muy limitada y, en algunos casos, incluso la etiología de la infección sigue sin estar clara. Entre los principales factores responsables de esta falta de información sobre la importancia de las micosis en medicina animal suele destacarse la escasa formación micológica de los profesionales veterinarios. Mediante el presente “Atlas de Micología Clínica Veterinaria”, de acceso gratuito y 100% online, pretendemos que los estudiantes de Veterinaria y otras titulaciones afines vayan adquiriendo conocimientos básicos sobre los principales hongos filamentosos, levaduras y microalgas de importancia clínica en medicina animal. El Atlas está optimizado para ser visualizado tanto en pantallas de ordenadores personales como en dispositivos móviles.

    In vitro activity of fidaxomicin and combinations of fidaxomicin with other antibiotics against Clostridium perfringens strains isolated from dogs and cats
    (BMC, 2023-11-16) Álvarez Pérez, Sergio; Anega, Blanca; Blanco Cancelo, José Luis; Hernandez, Marta; García Sánchez, Marta Eulalia
    Background: Previous studies have demonstrated that fidaxomicin, a macrocyclic lactone antibiotic used to treat recurrent Clostridioides difficile-associated diarrhea, also displays potent in vitro bactericidal activity against Clostridium perfringens strains isolated from humans. However, to date, there is no data on the susceptibility to fidaxomicin of C. perfringens strains of animal origin. On the other hand, although combination therapy has become popular in human and veterinary medicine, limited data are available on the effects of antibiotic combinations on C. perfringens. We studied the in vitro response of 21 C. perfringens strains obtained from dogs and cats to fidaxomicin and combinations of fidaxomicin with six other antibiotics. Results: When tested by an agar dilution method, fidaxomicin minimum inhibitory concentrations (MICs) ranged between 0.004 and 0.032 μg/ml. Moreover, the results of Etest-based combination assays revealed that the incorporation of fidaxomicin into the test medium at a concentration equivalent to half the MIC significantly increased the susceptibility of isolates to metronidazole and erythromycin in 71.4% and 61.9% of the strains, respectively, and the susceptibility to clindamycin, imipenem, levofloxacin, and vancomycin in 42.9–52.4% of the strains. In contrast, ¼ × MIC concentrations of fidaxomicin did not have any effect on levofloxacin and vancomycin MICs and only enhanced the effects of clindamycin, erythromycin, imipenem, and metronidazole in ≤ 23.8% of the tested strains. Conclusions: The results of this study demonstrate that fidaxomicin is highly effective against C. perfringens strains of canine and feline origin. Although fidaxomicin is currently considered a critically important antimicrobial that has not yet been licensed for veterinary use, we consider that the results reported in this paper provide useful baseline data to track the possible emergence of fidaxomicin resistant strains of C. perfringens in the veterinary setting.

    Analysis of the culturable gut yeast microbiota of dogs with digestive disorders
    (Elsevier, 2024-01-09) Álvarez Pérez, Sergio; Rodríguez Franco, Fernando; Sainz Rodríguez, Ángel; García Sánchez, Marta Eulalia; García-Sancho Téllez, Mercedes Guadalupe; Tercero-Guerrero, Daniela; Blanco Cancelo, José Luis
    Despite the increasing interest in studying the gut mycobiota of dogs, the association between fungal colonization and the development of digestive disorders in this species remains largely understudied. On the other hand, the high prevalence of antifungal-resistant yeasts detected in previous studies in samples from animals represents a major threat to public health. We analyzed the presence of culturable yeasts in 112 rectal swab samples obtained from dogs with digestive disorders attended in a veterinary teaching hospital. Our results revealed that Malassezia pachydermatis was frequently isolated from the studied dog population (33.9% of samples), and that the isolation of this yeast was significantly associated to the age of animals, but not to their sex, disease group, or the presence of vomits and/or diarrhea. In contrast, other yeast species were less prevalent (17.9% of samples in total), and their isolation was not significantly associated to any variable included in the analysis. Additionally, we observed that 97.5% of the studied M. pachydermatis isolates (n = 158, 1–6 per positive episode) displayed a minimum inhibitory concentration (MIC) value >4 μg/ml to nystatin, 31.6% had a MIC ≥32 μg/ml to fluconazole, and 27.2% had a MIC >4 μg/ml to amphotericin B. The antifungal susceptibility profiles of non-Malassezia (n = 43, 1–7 per episode) were more variable and included elevated MIC values for some antifungal-species combinations. These results confirm that the intestine of dogs is a reservoir of opportunistic pathogenic yeasts and suggest that the prevalence of M. pachydermatis colonization depends more on the age of animals than on any specific digestive disorder.

    Presence of Aspergillus fumigatus with the TR34/L98H Cyp51A mutation and other azole-resistant aspergilli in the air of a zoological park
    (Elsevier, 2023-11) Álvarez Pérez, Sergio; García Sánchez, Marta Eulalia; Martínez Nevado, Eva; Blanco Cancelo, José Luis
    Antifungal-resistant fungi, including Aspergillus fumigatus and other Aspergillus species, pose an urgent threat to human and animal health. Furthermore, the environmental route of azole resistance selection due to the widespread use of azole fungicides in crop protection and other applications is a major public health issue. Although environmental surveillance of fungi is frequently performed in many zoological parks and wildlife rehabilitation centers, the antifungal susceptibility of recovered isolates is only rarely analyzed, which precludes a clear assessment of the threat posed by these fungi to captive animals. In this study, we assessed the presence of airborne azole-resistant Aspergillus spp., including the so-called ‘cryptic species’ (i.e., species which are phenotypically similar to more well-known aspergilli but clearly constitute different phylogenetic lineages) in a zoological park located in the city of Madrid, Spain. In general, our results revealed a low prevalence A. fumigatus and cryptic aspergilli with decreased susceptibility to azoles. However, we detected an A. fumigatus isolate with the TR34/L98H mutation in the gene encoding the lanosterol 14α-demethylase (Cyp51A), consisting of a tandem repeat of 34 base pairs in the promoter region and a lysine to histidine substitution at codon 98. Notably, this TR34/L98H mutation has been linked to the environmental route of azole resistance selection, thus highlighting the ‘One Health’ dimension of the emerging problem of antifungal resistance. In this context, continuous environmental surveillance of azole-resistant aspergilli in zoological parks and other similar animal facilities is recommended.

    Active surveillance of antimicrobial resistance in companion animals: A pilot study in a Spanish Veterinary Teaching Hospital
    (Elsevier, 2024-04-02) Scarpellini, Raffaele; Leal Vélez de Mendizábal, Laura; Quevedo Caraballo, Sergio; Blanco Cancelo, José Luis; García Sánchez, Marta Eulalia; Pérez Sancho, Marta; Portero Fuentes, Miriam; Penelo Hidalgo, Silvia; Esposito, Erika; Mondo, Elisabetta; Piva, Silvia
    The role of small animal veterinary hospitals in the onset and dissemination of antimicrobial-resistant organisms (AMROs) is still not clear, and the implementation of an internal surveillance systems is a cost-effective tool to better understand their impact. The aim of this study was to describe a pilot program of active surveillance in a Spanish Veterinary Teaching Hospital, developed to estimate the detection frequency of AMROs in the commensal flora of patients and in the environment. Surveillance was focused on Methicillin-resistant Staphylococci (MRS), third generation cephalosporins resistant gram-negative bacteria (3GCR-GNB), and carbapenems-resistant gram-negative bacteria (CR-GNB). Oral and perirectal swabs were collected in the same dogs and cats hospitalized > 48 h, at their admission and before their discharge. Out of 50 patients sampled, 24% (12/50) were carriers at admission of at least one of the three investigated AMROs. Twenty-eight percent of patients (14/50) acquired at least one AMRO during the hospital stay. MRS detection frequency at admission was 12% (6/50), while acquisition was 6% (3/50). 3GCR-GNB detection frequency was 14% at admission (7/50) and acquisition 22% (11/50), while CR-GNB detection frequency was 2% at admission (1/50) and acquisition 2% (1/50). Environmental surveillance (98 samples) showed a total detection frequency of 22.4% for MRS (22/98), 2% for 3GCR-GNB and CR-GNB (2/98). Clinical staff’ shoe soles showed high detection frequency for MRS (50%). 3GCR Escherichia coli was the most isolated species in patients (n = 17). The results show how active surveillance can be used as a tool to assess the impact of AMROs in veterinary hospitals to subsequently build up tailored control plans based on specific issues.
