Thus, the ability of several povidone-iodine (PVP-I) products to inactivate SARS-CoV-2 was evaluated based on their in vitro inactivation efficacy. PVP-I solutions such as Isodine Gargle® (ethical and consumer products), Isodine Gargle C®, and Isodine Nodo Fresh® for 30 or 60 s decreased the viral infectivity level from 2-4 × 106 TCID50/ml to below the detectable level (> 99.9% reduction). Our results indicate that the use of Isodine® mouthwash and gargle products is an effective infection control measure against SARS-CoV-2.","PeriodicalId":56285,"journal":{"name":"Japanese Journal of Veterinary Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42532411","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}

A total of 160 dogs were used. The animals were evaluated in four groups as control and those with bacterial, viral, and parasitic infections. Serum procalcitonin, tumor necrosis factor-alpha (TNF- α ), interleukin-1 beta (IL-1 β ), interleukin-6 (IL-6), interferon-gamma (IFN- γ ) level, and total white blood cell (WBC), and differential leukocyte count were determined. Serum procalcitonin level was found to be higher in dogs with bacterial infection compared to the control group and dogs with viral disease ( P = 0.019). It was observed that serum procalcitonin level in dogs with bacterial infection varies related to the disease agent and it was found higher in those with pyometra ( P = 0.009). Serum procalcitonin level was higher in dogs which had parasitic infections but, the difference is not significant. IL-6 level was found higher in dogs with viral and parasitic diseases than those in the control ( P = 0.006). A negative correlation was determined between procalcitonin and IFN- γ ( P = 0.001). While a positive correlation was detected between procalcitonin and WBC count, a negative correlation was determined between procalcitonin and monocyte percentage. In conclusion, serum procalcitonin level can be used as a clinical biomarker in bacterial diseases and, perhaps, in some parasitic diseases in dogs. However, further studies should be conducted to determine threshold values that take the severity of infection, its prevalence, and clinical course into account.","PeriodicalId":56285,"journal":{"name":"Japanese Journal of Veterinary Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41285184","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}

Cryptosporidium parvum virus type 1 (CSpV1) is the first member within the Partitiviridae family recognized to infect protozoan hosts. Cryptosporidium tracking based on CSpV1 detection has been attempted; however, each study used different conditions for the PCR protocol, primers, and target viral sequences. Accordingly, the sensitivity of PCR-based CSpV1 detection remains unclear. In addition, oocyst purification from clinical samples can be problematic due to small number of oocysts, sample degradation and low yield efficiency of currently used purification methods. Here we show that the second half of the coding region of dsRNA2 can be detected from various types of clinical samples, without the need for oocyst purification, by using a semi-nested-PCR technique. Furthermore, we show that the short sequence targeted in this study has higher diversity than the Cryptosporidium GP60 gene. Taken together, our findings suggest that this method could be used as an important tracking marker for Cryptosporidium species.","PeriodicalId":56285,"journal":{"name":"Japanese Journal of Veterinary Research","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49036318","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}

Four 180-day-old male Guanzhong Black (GZB) pigs and six male Landrace piglets (including three 30-day-old and three 7-day-old pigs) were collected to study Setd8 gene.

Moreover, the expressions of the two Setd8 variants were significantly higher in testis than brain of GZB pig (P < 0.05). Further study on testis showed that the mRNA expression of Setd8a variant was significantly lower than Setd8b variant in 30-day-old and 7-day-old pigs (P < 0.05).
