Cryptosporidium is a common intestinal protozoan that can lead to diarrhea in humans and dogs. The predominant species of infection are C. hominis and C. parvum in humans, and C. canis in dogs. However, C. canis can infect immunocompromised humans. Considering the close contact with humans, dogs have the potential to be reservoirs for human cryptosporidiosis. Breeding kennels are the major supply source of puppies for pet shops. The present study is to determine the molecular prevalence and characteristics of Cryptosporidium spp. found in breeding kennel dogs. A total of 314 fecal samples were collected from young and adult dogs kept in 5 breeding kennels. A polymerase chain reaction targeting the small subunit rRNA gene was employed for the detection of Cryptosporidium spp. To determine the species, the DNA sequences were compared to GenBank data. Overall, 21.0% of the fecal samples were positive for Cryptosporidium spp. infection. Cryptosporidium spp. was detected in all 5 facilities. A sequencing analysis demonstrated that all isolates shared 99-100% similarity with C. canis. The results suggest that Cryptosporidium spp. infection is present at a high-level in breeding kennel dogs. However, because dominant species in this survey was C. canis, the importance of breeding kennel dogs as reservoirs for Cryptosporidium spp. transmission to humans is likely to be low in Japan.

We described a human case of zoonotic dog tapeworm, Dipylidium caninum (Eucestoda: Dilepidiidae), rarely occurring in China. The mother of a 17 month-old boy noted the appearance of small white and active worms over a month period in her son's feces, but the boy was asymptomatic except mild diarrhea. We observed 3 tapeworm proglottids resembling cucumber seeds in his stool sample. Microscopically, each proglottid had 2 genital pores, 1 on each lateral edge, and numerous egg capsules in the uterus. The patient was successfully treated with a single oral dose of praziquantel. Adult worms were recovered in the diarrheic stool after praziquantel treatment and purgation. His family had household pet dogs for several years, and he might have acquired the infection by ingestion of infected fleas of his pet dogs. A history of dog or cat pets and flea bites may be important clues to diagnosis of D. caninum infection. The infected pets should also be treated.

Serial ultrasonographic examinations were daily performed on 11 bitches (5 Maltese and 3 Yorkshire terrier) from day 15 until parturition to determine the time of Sift detection and ultrasonographic appearance of the fetal and extra-fetal structures. Gestational age was timed from the day of ovulation (day 0), which was estimated to occur when p18sma progesterone concentration was first increased above 4.0 ng/ml. The gestational length in 8 bitches was 61.5 (range: 60-64) days. The initial detection time of fetal and extra-fetal structures were: gestational sac at days 20.5 (18-23); zonary placenta in the uterine wall at days 25.4 (24-30); yolk sac membrane at days 25,5 (23-37); amniotic mombrane at days 28.7 (25-32); embryo initial detection at days 23.3 (20-26); fetal heartbeat at days 23.9 (21-27); fetal movement at days 31.3 (26-34); limb buds at days 32.1 (29-35); rotomarh at days 35.3 (32-40); urinary bladder at days 35.6 (33-39); skeleton at days 37.8 (37- 40) and kidney at days 45.3 (41-49), respectively.

본 연구는 반려동물을 돌보는 반려인 11인의 질적 인터뷰를 통해 반려동물 돌봄과 관련한 인터넷 소비 현상을 분석했다. 본 연구에서는 그동안 전혀 다루지 않았던 길고양이 돌보미를 인터뷰 대상인, 반려동물 소비자로 포함했다. 인터넷 소비는 개와 고양이의 종 차에 따라 다르게 나타났다. 개의 반려인들은 고양이에게는 필요하지 않은, 목욕제품, 미용기구, 옷, 하네스, 유모차 등을 많이 구입했다. 그동안 펫 푸어(pet-poor) 현상은 자신에게 소비할 돈을 절약하여 반려동물을 위해 소비하는 행동을 보이는 젊은 소비자들에게 많이 나타난다고 알려졌다. 그러나 이번 연구에서 펫 푸어 현상은 중장년, 노년층에서도 나타났으며 이들은 경제적으로 넉넉하지 않아도 반려견을 위해 값비싼 옷, 하네스 등을 구매하는 것으로 드러났다. 또한 중장년 여성의 길고양이 돌봄이도 펫 푸어로의 전락 가능성을 경계하고 있음을 알 수 있었다. 또한 반려동물용품의 인터넷 소비는 젠더 차이를 보인다고 할 수 없었다. 대체로 가족을 위해 생필품 구매를 주로 해 오던 여성이 반려동물용품도 온라인으로 구매했고, 부인이 인터넷 사용에 서툰 경우에는 남편이 대신 온라인으로 반려동물용품을 구매했다.

1. The sixty raised shepherd and sixty-five inhoused pet dogs in the regions of Daejon and Cheongju were subjected to investigate the TB infection by means of BCG and X-ray diagnosis. The 5 out of 65 inhoused pet and 7 out of 60 shepherd dogs were observed to be infected with TB, respectively. However, none of Mycobacterium species were detected from lung tissues of 4-slaughtered dogs showing BCG positive reaction. 2. The rats were first inoculated with 0.1ml BCG, and then 0.1ml M bovis suspended solution($1{\times}10^5$ organisms/0.2ml) 3weeks later. After 5 months, the animals were killed. The pathohistological results from both groups, TB inoculated and BCG treated groups, were observed on the surface of lung. Furthermore, the severe pathological lesion in the Iung was observed in M bovis inoculated group compared to BCG treated group. 3. The slight macrophage invasion and granuloma formation in the lung from BCG treated group were observe individually. However, it was confirmed that the lung from M bovis treated group was invaded by the macrophages and neutrophils combined with the granuloma formation. 4. When the numbers of the total cells taken from broncho-alvealar fluid in each of mouse from both groups were differentially counted, the number of total cell, neutrophils, and lymphocytes from M bovis treated group were significantly increase compared with those of BCG treated group. 5. Although there were nearly no response of the alveolar macrophages to CSF in serum obtained from control group, those from M boris treated group were significantly proliferated.

Heavy metal pollution has become a serious health concern in recent years. Dogs are a very good indicator of the pollution load on the environment. They share people's environment and are exposed to the action of the same pollutants. This study estimated the heavy metal contents in the serum of dogs in domestic districts, and assessed the age, sex, feeding habits, living area, breeding environment and smoking habit of the owners. The findings suggest that dogs can be used to monitor the environmental quality of heavy metals. The mean concentrations of heavy metals in the dog serum from 204 samples (108 male and 96 female) were 0.22${\pm}$0.01 $\mu$g/ml, 0.24${\pm}$0.04 $\mu$g/ml, 0.61${\pm}$0.08 $\mu$g/ml, and 0.50${\pm}$0.06 $\mu$g/ml (for Cd, Hg, Pb, and Cr), respectively. Concentrations of Pb, Cd, Hg, and Cr in the dog serum were higher in Yeongnam including Ulsan, and Seoul higher than those of Chungchong and Honam, especially Pb concentration, which was significantly higher (p<0.01). Concentrations of Cd, Hg, Pb, and Cr in serum, were increased by age (p<0.05). When commercial pet food was provided to dogs, Cd and Cr concentrations were significantly higher in dog serum than dogs fed a human diet (p<0.01 in Cd and p<0.05 in Cr). Heavy metal concentrations of dogs owned by smoking owners, were higher than non-smoking owners although there was no significant difference.

Dogs are a very good indicator of the pollution load on the environment. They share people's environment and are exposed to the action of the same pollutants. This study was to estimate the heavy metal contents in dog hairs in domestic districts, and to assess effects of age, sex, feed habits, living area, breeding environment and smoking habit of owner. The mean concentrations of heavy metals in 204 samples were 0.09${\pm}$0.10 ${\mu}g$/g, 0.21${\pm}$0.09 ${\mu}g$/g, 0.82${\pm}$0.09 ${\mu}g$/g and 0.48${\pm}$0.07 ${\mu}g$/g (Cadmium (Cd), Mercury (Hg), Lead (Pb) and Chromium (Cr)) in dog hairs, respectively. Concentrations of Pb, Cd, Hg and Cr in dog hairs in Yeongnam including Ulsan and Seoul, were higher than in Chungchong and Honam, and concentrations of Pb were significantly different (p<0.01). Concentrations of Cd, Hg, Pb and Cr in dog hairs increased with age (p<0.05). Only dogs fed commercial pet foods had significantly higher Cd and Cr concentrations in hairs than dogs fed dog feed and human diet (p<0.01 in Cd and p<0.05 in Cr). Cr concentrations of dog hairsfrom dogs kept on cement floors were the highest of the other environments (p<0.01). Heavy metal concentrations of dogs owned by smokers, were higher than dogs of non-smokers, but there were no significant differences.

Atopic dermatitis, caused by immune hyper-responsiveness, is wide spread in humans as well as in the dogs, especially in industrialized condition. Pet dogs are generally exposed to the same environment as their owners, and a significant portion of these animals are also known to suffer from this allergic disease. However, diagnosis and treatment methods of atopic dermatitis in animals have not been well established. We explored the possibility of using recently developed PG102 for the treatment of atopic dermatitis in the canine population. PG102 is a water soluble extract prepared from Actinidia arguta, and has been shown to produce significant therapeutic effect in variable allergy animal models. After oral administration of PG102 at a dose of 12.5 mg/kg daily for 4 weeks, severity of disease was greatly improved. IgE is one of representative members used to diagnose allergic diseases in humans. However, it is not well established whether there is any correlation between the serum level of IgE and atopic dermatitis. Our data indicated that dogs diagnosed to have atopic dermatitis contained higher level of serum IgE than the normal dogs and that treatment of dogs with PG102 significantly lowered the serum level of IgE. Taken together, this study demonstrated that PG102 treatment yielded significant amelioration of canine atopic dermatitis and down-regulation of serum IgE and that the serum level of IgE can be used as a convenient member for diagnosis of atopic dermatitis in dogs.
