In this study we investigated maternal Helicobacter felis (H. felis) infection status to determine the potential of maternal transmission. Pregnant Beagle dogs were infected experimentally with H. felis. Following the experimental design, the stools of the mother and litters were isolated and assessed for transmission of H. felis at parturition day, 1-week old age and 6-week old age respectively. Polymerase chain reaction (PCR) was used to examine the presence of transmitted H. felis. All litters showed no transmission of H. felis at parturition day. However, they revealed 14.3% and 100% at 1-week old age and 6-week old age respectively by PCR. These results suggested that vertical infection during prenatal period or delivery procedure is unlikely as a route of mother-to-child H. felis infection. It might be acquired H. felis through breast-feeding, contaminating saliva and fecal-oral during co-habitat.

4.Factors Influencing COVID-19 AstraZeneca (ChAdOx1) Vaccination and Side Effects among Health Care Workers in an Acute General Hospital
Journal of Korean Biological Nursing Science 2021;23(4):318-329
Purpose:
This study was conducted to identify factors affecting COVID-19 vaccination and associated side effects among health care workers in a small and medium-sized hospital.
Methods:
In May 2021, 301 workers out of a total of 670 working in a small and medium-sized hospital in Gyeonggi-do, were surveyed. The small and medium-sized hospital treats patients with COVID-19. Health care workers across different medical institutions responded with self-reported internet questionnaires. Factors influencing COVID-19 vaccination were analyzed via logistic regression.
Results:
Out of 301 subjects, 89.0% showed an intention to inoculate, and 85.7% were vaccinated against COVID-19. The most frequent reason for vaccination was responsibility as a medical worker. The fear of adverse reactions was the most frequent reason for non-vaccination. Adverse reactions after inoculation occurred in 70.9% of cases, and 30.6% were referred for treatment of adverse reactions. The factors ultimately influencing COVID-19 vaccination were vaccination intention, previous side effects from other vaccinations, occupation, and age.
Conclusion
In order to improve the effectiveness of COVID-19 vaccination, a systematic approach is required to determine the risk factors associated with the young age of the administrative staff/ personnel, subjects with a history of side effects associated with other vaccines, and health care workers who do not intend to be vaccinated. It is important to develop strategies to improve immunization. In addition, accurate and essential information regarding the side effects of vaccination is needed, along with appropriate education and publicity.

Journal of the Korean Society of Emergency Medicine 2022;33(3):262-270
Objective:
Gastrointestinal (GI) bleeding is one of the most common reasons for people to visit the emergency department. Despite advances in treatments, the intensive care unit (ICU) admission rates due to GI bleeding are still high. Therefore, many scoring systems had been developed to screen patients who need active care. Among these scoring systems, the AIMS65 score, Glasgow-Blatchford score (GBS), and Pre-Rockall score (PRS) are known to be accurate risk assessment scoring models. A recent study has shown that hypoalbuminemia is related to poor prognosis in patients with GI bleeding. In this study, we compared the prognostic performance of the blood urea nitrogen to serum albumin ratio (B/A ratio) with the AIMS65, GBS, and PRS scores in patients with GI bleeding.
Methods:
This is a retrospective cohort study of patients presenting with GI bleeding in the Seoul Regional Emergency room from February to December 2018. The baseline characteristics of these patients were obtained. The data were compared with the prevalence of ICU admission from the emergency department and in-hospital mortality. The B/A ratio, AIMS65, GBS, and PRS scores as predictors of ICU admission and in-hospital mortality were evaluated using the area under the receiver operating characteristic (AUROC) curve.
Results:
A total of 433 patients were included in this study. Of these, 354 (81.8%) were admitted to the hospital, 121 (27.9%) were admitted to the ICU, and 26 (6.0%) died during hospitalization. Multivariate logistic regression analysis revealed that the B/A ratio was a significant predictor of ICU admission and in-hospital mortality. The predicting ICU admission AUROC value of the B/A ratio was 0.735, and those of the AIMS65, GBS, and PRS scores were 0.763, 0.741, and 0.704, respectively. For predicting in-hospital mortality, the AUROC value of the B/A ratio was 0.758, and those of the AIMS65, GBS, and PRS scores were 0.826, 0.717, and 0.744, respectively.
Conclusion
The B/A ratio is a useful tool for predicting the prognosis for patients with GI bleeding as are the AIMS65, GBS, and PRS score models.

Canine respiratory coronavirus (CRCoV) is commonly associated with canine kennel cough worldwide. Clinically infected dogs present coughing, sneezing, and nasal discharge. Severe infections may progress to pneumonia. Through serological surveys, CRCoV has been identified as a worldwide pathogen found in the respiratory tracts of dogs suffering from mild or severe respiratory disease. In this study, three dogs were obtained from a dog kennel. Over the previous 5 days, the dogs showed coughing, sneezing, and nasal discharge. To detect the etiologic pathogen, we performed multiplex RT-PCR (mRT-PCR) to amplify the genes encoding canine influenza virus matrix protein, canine distemper virus nucleocapsid protein, and CRCoV spike protein. Dot blotting was achieved with a CRCoV-specific probe. Nasal-secreting CRCoV was detected by the 442 bp CRCoV-positive PCR reaction in the nasal swabbing samples from dogs. Further, CRCoV-positive reactions by dot blot hybridization were detected in the nasal swabbing samples from dogs. In conclusion, we detected CRCoV in kenneled dogs with respiratory disease in Korea. Multiplex RT-PCR was able to detect successfully CRCoV infection in dogs. We suggest that mRT-PCR would be useful and effective for monitoring CRCoV infection in various kinds of dogs.

Cell culture systems for the protozoan Eimeria are not yet available. The present study was conducted to develop an animal model system by inoculating animals with a live Eimeria vaccine. This study was conducted on 3-day-old chickens (n = 20) pretreated with cyclophosphamide. The chickens were divided into 2 groups: the control group (n = 10) and the inoculated group that received the live Eimeria vaccine (n = 10). During the study period, we compared the clinical signs, changes in body weight, and number of oocysts shed in the feces of the control and inoculated group. This study showed that oocyst shedding was significantly higher in the chickens inoculated with live Eimeria oocysts than in the control chickens. Moreover, body weight gain was lesser in the animals in the inoculated group than in the control animals. Fecal oocyst shedding was observed in the inoculated animals. On the basis of these findings, we suggest that live Eimeria vaccination with cyclophosphamide pretreatment may be used to obtain an effective animal model for studying protozoan infections. This animal study model may eliminate the need for a tedious continuous animal inoculation process every 6 months because the live coccidiosis vaccine contains live oocysts.

A male one year-old beagle dog with unilateral cryptorchism was presented for investigation of reduced appetite. Abdominal sonography and radiography demonstrated abnormal enlargement of the left testicle in the abdominal cavity. Both the retroperitoneal cryptorchid testicle and the other contralateral testicle were removed surgically. The retroperitoneal cryptorchid testicle was an enlarged, firm and bulging sphere mass. The cut surface revealed a homogeneous white color. The contralateral testicle in the scrotum showed an almost normal appearance. Histopathologically, the retroperitoneal cryptorchid testicle was diagnosed as a Sertoli cell tumor. This report describes a case of Sertoli cell tumor with cryptorchism in a beagle dog.

Laboratory Animal Research 2011;27(2):141-145
Mycoplasmas are highly fastidious bacteria, difficult to culture and slow growing. Many species of mycoplasmas are important pathogens that cause respiratory infection in laboratory animals and that are known to affect experimental results obtained with contaminated animals. The aim of the present study was to develop a sensitive and specific assay for the detection of mycoplasma species. To this end, we developed a polymerase chain reaction and dot blot hybridization assay (PCR/DBH) for detecting mycoplasma DNA and evaluated it for its sensitivity and specificity. Mycoplasma consensus primer pairs were used for the amplification of target DNA. When PCR product was visually detected, the limit of detection of the PCR test was 10(2) pg of mycoplasma purified DNA. For DBH, the amplified DNA was labeled by incorporation of digoxigenin (DIG). This DIG-labeled probe was capable of detecting 10(4) pg of purified mycoplasma DNA by DBH. PCR/DBH was more sensitive than PCR or DBH alone and was also very specific. Our PCR/DBH assay can be applied efficiently to confirm the presence of mycoplasma species on clinical samples and to differentiate between mycoplasma species infection and other bacterial infections.

Eimeria tenella and Eimeria maxima are important pathogens causing intracellular protozoa infections in laboratory avian animals and are known to affect experimental results obtained from contaminated animals. This study aimed to find a fast, sensitive, and efficient protocol for the molecular identification of E. tenella and E. maxima in experimental samples using chickens as laboratory avian animals. DNA was extracted from fecal samples collected from chickens and polymerase chain reaction (PCR) analysis was employed to detect E. tenella and E. maxima from the extracted DNA. The target nucleic acid fragments were specifically amplified by PCR. Feces secreting E. tenella and E. maxima were detected by a positive PCR reaction. In this study, we were able to successfully detect E. tenella and E. maxima using the molecular diagnostic method of PCR. As such, we recommended PCR for monitoring E. tenella and E. maxima in laboratory avian facilities.
