Mammals of the superorder Xenarthra can harbor and transmit several pathogens, acting as important sources of infection for spreading various zoonoses. Microsporidia have not yet been described in this group of animals, the aim of this study was to analyze the occurrence of the zoonotic microsporidian Encephalitozoon intestinalis, Encephalitozooncuniculi and Enterocytozoon bieneusi in the feces of giant anteater (Myrmecophaga tridactyla) and armadillo species (Priodontes maximus, Euphractus sexcinctus, Dasypus novemcinctus, Cabassous squamicaudis) monitored by Wild Animal Conservation Institute (ICAS) in Brazil. Fecal samples (n=127) were subjected to DNA extraction with the QIAamp Fast DNA Stool Mini Kit. Amplification by PCR was performed with generic primers and the product generated from this reaction was subjected to nested PCR with specific primers. Eleven samples tested positive for E. intestinalis, two from M. tridactyla (2/56, 3.6%), seven from E. sexcinctus (7/51, 13.7%), two from P. maximus (2/11, 18%) and one from C. squamicaudis (1/3, 33.3%). There was a predominance of positive results in adult animals, of both sexes across and in the Pantanal and Cerrado biomes. In conclusion, the prevalence in Xenarthra was 9.4%, with a higher occurrence in armadillos than in anteaters. Therefore, the species of wild mammals studied here should be considered reservoirs of microsporidian pathogens and have a relevant role in the concept of One Health.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Male and female mice were fed a high-fat/high-sucrose (HFS) diet for eight weeks. Two mouse models fed the HFS diet showed increases in urinary protein, kidney weight, and glomerular size, but these changes were pronounced in KK-Ay mice.

In addition, fat accumulation was observed in the macula densa of db/db mice and in the glomeruli of KK-Ay mice fed with the HFS diet.

However, azole-resistant strains have been isolated from canine skin and ear canals worldwide. Phytochemicals isolated from essential oils are effective alternatives for inhibiting Malassezia pachydermatis. To evaluate the usefulness of phytochemicals against azole-resistant isolates, we performed in vitro susceptibility testing using the phytochemicals carvacrol, citral, and thymol. Eight antifungal-resistant isolates were obtained from 7 cases of dermatitis and 1 case of otitis externa during 2022 and 2023 from dogs in Tokyo and Kanagawa, Japan. Fungal susceptibility to carvacrol, citral, and thymol were assessed using the modified broth microdilution method. The minimum inhibitory concentrations (MICs) of the phytochemicals in all isolates were as follows: 0.03 to 0.125% for carvacrol; 0.03 to 0.125% for thymol; and 0.03% to 0.125% for citral. Based on these results, carvacrol, citral, and thymol appear to be effective against azole-resistant strains.

The adrenal gland plays a key role in stress responses and has abundant vasculature, through which the hypothalamic-pituitary axis hormonally controls its activity. Understanding the arterial supply pattern to the gland is fundamental to understanding its function and performing experiments. We therefore traced the arteries supplying the adrenal gland in six male and nine female common marmosets using the latex injection method. The adrenal artery originates from one to four parent arteries, including the caudal phrenic, celiac, left gastric, gonadal, and renal arteries and the abdominal aorta. The branching pattern of the adrenal arteries was divided into Types 1 to 4, having 1-4 parent arteries, respectively. Type 2 was most frequent on the right side (seven of 15 halves, 46%), whereas Type 3 was most frequent on the left (eight of 15 halves, 53%). The number of cranial, middle, and caudal adrenal arteries ranged from one to four in the cranial, one to five in the middle, and one to six in the caudal adrenal arteries. The total number of adrenal arteries varied from three to 13, predominantly as five on one side. The present study revealed frequent individual variations in the origin and number of adrenal arteries in the common marmoset, which may be informative for further research involving the adrenal glands in this species.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"123-130"},"PeriodicalIF":1.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11830446/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142830629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Belugas (White Whale, Delphinapterus leucas), belonging to the family Monodontidae, are of considerable importance and often the centerpiece of aquarium collections worldwide. This study aimed to investigate the effects of the administration of prebiotics on the gut microbiota and overall health of the beluga. Prebiotic 1-kestose, a fructooligosaccharide comprising sucrose and fructose, was administered to three belugas, alongside their regular vitamin supplements for a duration of 8 weeks. 16S rRNA gene amplicon sequencing of intestinal DNA revealed that the relative abundance of the genus Turicibacter, a potentially pathogenic bacteria, significantly reduced after 1-kestose administration when compared to that at baseline (P=0.050). In addition, a quantitative PCR analysis revealed that the levels of collagenase gene, a putative virulence factor gene of Turicibacter, significantly reduced after 1-kestose administration (P=0.050). Blood creatinine levels that were initially above the normal value also reduced after 1-kestose administration (P=0.023). Therefore, this study demonstrated the potential of 1-kestose to improve the health and welfare of aquarium belugas.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"152-159"},"PeriodicalIF":1.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11830438/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142781712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
