The benefits of probiotics for the improvement of animal health status have been of great interest in recent years. For this reason, in this study was aimed at assessing a strain with probiotic potential to be added to the feed. Therefore, the objective of this trial is to use a strain with probiotic potential isolated from the intestinal microbiota of Helix aspersa Müller to subsequently add it to the feed of this species to improve its health status. So, the strain is characterized, and its probiotic potential is demonstrated. Finally, with the aim of preserving the probiotic strain by freeze-drying so that it can later be added to the feed, different cryoprotectants were studied that could give it a higher survival rate over time. The cryoprotectant that gives the best result with strain survival rate is trehalose 15%.

There are some reports about the risk of manipulating wild hedgehogs since they can be reservoirs of potential zoonotic agents like dermatophytes. The aim of this study was to describe the integument mycobiota, with special attention to dermatophytes of wild European hedgehogs. Samples from spines and fur were cultured separately in Sabouraud dextrose agar (SDA) with antibiotic and dermatophyte test medium (DTM) plates. Nineteen different fungal genera were isolated from 91 cultures of 102 hedgehogs. The most prevalent genera were Cladosporium (79.1%), Penicillium (74.7%), Alternaria (64.8%), and Rhizopus (63.7%). A lower prevalence of Aspergillus (P = 0,035; χ 2 = 8,633) and Arthrinium (P = 0,043; χ 2 = 8,173) was isolated during the spring time and higher frequencies of Fusarium (P = 0,015; χ 2 = 10,533) during the autumn. The prevalence of Acremonium was significantly higher in young animals (70%, 26/37) than in adults (30%, 11/37) (P = 0,019; χ 2 = 5,915). Moreover, the majority of the saprophytic species that grew at the SDA culture were also detected at the DTM. Finally, no cases of ringworm were diagnosed and no dermatophytes spp. were isolated. Concluding, this study provides the first description of fungal mycobiota of the integument of wild European hedgehogs in Spain, showing a large number of saprophytic species and the absence of dermatophytes.

Endometritis is associated with fertility problems in many species, with endometrial biopsy being the main diagnostic tool. In feline queens, the reduced size of the uterus may make it difficult to obtain representative diagnostic samples. Endometrial cytology may represent a valuable diagnostic tool for evaluating the health status of the endometrium in queens. Fifty domestic shorthair queens were included and divided into two cytological diagnostic technique groups, the uterine lavage (UL; n = 28) and uterine swabbing (US; n = 22) groups. Cytological results were compared with histopathological and bacteriological information. Changes in the histopathological patterns were also evaluated and compared with progesterone levels to confirm previous published data. Furthermore, the results from both cytological sampling methods were compared to evaluate the utility of each method. Endometritis was ruled out in all queens by means of histology and microbiology. Leukocyte counts and red blood cell/endometrial cell ratios were significantly higher in US than UL samples. Additionally, UL sampling is less affected by blood contamination and cells are better preserved. The combination of endometrial cytology and uterine culture might be useful for evaluating the endometrial characteristics in queens. The UL evaluation method is more representative of the actual endometrial status than the US technique.

Mycotoxins are secondary metabolites produced and accumulated by mould. This study assessed the ability of 89 lactic acid bacteria, isolated from different sources, to degrade two mycotoxins by Alternaria: alternariol and altenuene. The mehodology employed was the thin layer chromatography. The results obtained allow us to demonstrate that a 16.85% of the strains (15/89 strains) are capable of decreasing the intensity of the band related at the alternariol and 14.60% (13/89 strains) is capable of decrease the intensity of the band that manifests the altenuane in Alufolium. All tests have been observed under wavelengths of 360 nm and 255 nm. The results obtained allow carrying out a selection of lactic acid strains capable of degrading or decreasing the concentration of mycotoxins selected for this.
