The purpose of this case report is to describe and document a rare anatomical variation of a moderator band located in right ventricle of a stallion referred for cryptorchid castration. During routine pre-anesthetic echocardiography, a thick moderator band was detected crossing the right ventricle. No other cardiovascular abnormalities were identified. Anesthesia and recovery occurred uneventfully. This variation is important not only for anatomy but also for the evaluation of normal heart both during ultrasound and electrocardiographic examination.

Equine pastern dermatitis (EPD) is a multifactorial disease with a change in the skin microbiome. The present study monitored the influence of Weissella cibaria Biocenol™ 4/8 D37 CCM 9015 stabilized on alginite on the skin microbiota of healthy horses and model patients with EPD. Based on clinical signs, EPD lesions were identified as exudative or proliferative forms. A comparison of the initial microbial community based on 16S rRNA amplicon sequencing revealed that there was a statistically significant difference between healthy vs. exudative ( R  = 0.52, p  = 0.003) and exudative vs. proliferative communities ( R  = 0.78, p  = 0.043). The healthy skin microbiota was dominated by the families Corynebacteriaceae (19.7 ± 15.8%) and Staphylococcaceae (15.8 ± 10.7%). Streptococcus (11.7 ± 4.1%) was the dominant genus in the exudative group together with Corynebacterium (11.0 ± 3.8%), while Staphylococcus (15.6 ± 14.5%) dominated the proliferative group. The genus Staphylococcus represented only 0.5% of the exudative skin microbial community, a major difference between EPD-affected lesion types. Upon application, there was a statistically significant shift in community composition in all the groups, including the healthy community; however, the change was the most significant in the exudative community. On average, the genus Weissella represented 80.0 ± 13.3% of the exudative and 49.0 ± 30.0% of the proliferative bacterial community during treatment. One week after the application period, richness and diversity increased and were comparable in all groups. The application of the W. cibaria strain was associated with a significant decrease of the genera Staphylococcu s, Moraxella, and Rothia in the proliferative group and with a decrease of Streptococcus and Clostridium in both exudative and proliferative groups. Based on our results, we conclude that a topically applied W. cibaria RIF R , stabilized on alginit, induced potentially beneficial shifts in the composition of the skin microbiota., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2025 Styková, Valocký, Kačírová and Fecskeová.)

The aim of this study was to draw attention to the risk of transmission of Encephalitozoon, Cryptosporidium and Blastocystis infection due to high animal migration and to point out that even wild animals can be a source of many zoonotic diseases. Encephalitozoon cuniculi, Cryptosporidium spp. and Blastocystis spp. are frequent microscopic organisms that parasitise humans, domestic and wild animals. Two hundred and fifty-five faecal specimens were collected from wild boars, badgers, wolves, bears, foxes and deer from 15 locations in Slovakia. Sequencing of positive PCR products and subsequent sequence comparison with GenBank sequences identified Blastocystis spp. in five wild boars. The ST 5 (n = 4) and ST 10 (n = 1) subtypes were determined by genotyping. We identified Encephalitozoon cuniculi in five wild boars, and genotype II (n = 5) was determined on the basis of ITS repeat sequences. Cryptosporidium scrofarum was sequenced in wolves (n = 4) and wild boars (n = 1), while Cryptosporidium suis only in wild boars (n = 2). None of the wild boars had a mixed infection.
