  • A male badger which showed depression and bloody diarrhea was submitted to Iksan Branch of Chonbuk Veterinary Service Laboratory for necropsy on May 1998. Grossly, paleness of the mucous membranes was observed and the small intestinal contents were hamorrhagic. The numerous tiny hookworms, sized in 5-10 mm and greyish-white in color, attached to the intestinal mucosa. Male bursa was well developed. Histologically, intestinal lumen was filled with hemorrhagic contents, which contained worms. The epithelial cells of the villi were underwent degeneration and lamina propria was infiltrated by lymphocytes and plasma cells, and goblet cells were hyperplastic. There were rounded cutting plates in the funnel-shaped buccal capsule and transverse striation on sheath in hookworm, ultrastructurally, which were consistent with Uncinaria sp. The shape of eggs were ellipsoidal and morula, and some eggs contained a mobile larva. It was concluded that this badger was infected with Uncinaria.

  • The present study was undertaken to identify the species of nematodes and determine infection state of small intestinal nematodes from dogs in Taegu area. One hundred and eleven healthy dogs which were 8 months old or more were examined by means of autopsy from September to November, 1993. All of the worms in small intestine were collected and preserved in 10% formalin solution. The worms were cleared in the lactophenol solution and examined by stereomicroscope and lightmicroscope. The result obtained were summarized as follows : Fifty three dogs(47.7%) out of the 111 experimental dogs were infected with small intestinal nematodes. Hookworm infection was recognized in 30(27.7%) dogs. All of the hookworms were identified morphologically as Ancylostoma caninum which had 3 pairs of ventral teeth, a pair of triangular dorsal teeth and a pair of centrolateral teeth. No Uncinaria stenocephala infection was detectable. Roundworm infection was recognized in 37(33.3%) dogs. Twenty one(18.9%) dogs were infected with Toxascaris leonina which had characteristic dorsal lips, paired spicules and a simple tail without process. The individual worm burden of the infected dogs ranged from one to 361 with mean of 25.5%. Among them 0~358(mean $17.8{\pm}30.66$) were Ancylostoma caninum, 0~18(mean $1.6{\pm}3.44$) were Toxocara canis and 0~60(mean $6.0{\pm}12.05$) were Toxascaris leonina. Single infection with Ancylostoma caninum, Toxocara canis and Toxascaris leonina were observed in 16(14.4%) dogs, in 9(8.1%) dogs, and in 11(9.9%) dogs respectively. Double infection with Ancylostoma caninum plus Toxascaris leonina and Toxocara canis plus Toxascaris leonina occurred in 5(0.5%) and in 3(2.7%) dogs respectively. Triple infection with Ancylostoma caninum plus Toxocara canis plus Toxascaris leonina occurred in 7(6.3%) dogs.

  • This study aimed to determine the prevalence of intestinal helminth parasitic infections and associated risk factors for the human infection among the people of Samarkand, Uzbekistan. Infection status of helminths including Echinococcus granulosus was surveyed in domestic and wild animals from 4 sites in the Samarkand region, Uzbekistan during 2015-2018. Fecal samples of each animal were examined with the formalin-ether sedimentation technique and the recovery of intestinal helminths was performed with naked eyes and a stereomicroscope in total 1,761 animals (1,755 dogs, 1 golden jackal, and 5 Corsac foxes). Total 658 adult worms of E. granulosus were detected in 28 (1.6%) dogs and 1 (100%) golden jackal. More than 6 species of helminths, i.e., Taenia hydatigena, Dipylidium caninum, Diplopylidium nolleri, Mesocestoides lineatus, Toxocara canis, and Trichuris vulpis, were found from 18 (1.0%) dogs. Six (T. hydatigena, Toxascaris leonina, Alaria alata, Uncinaria stenocephala, D. caninum, and M. lineatus) and 2 (D. nolleri and M. lineatus) species of helminths were also detected from 5 Corsac foxes and 1 golden jackal, respectively. Taeniid eggs were found in 2 (20%) out of 10 soil samples. In the present study, it was confirmed that the prevalences of helminths including E. granulosus are not so high in domestic and wild animals. Nevertheless, the awareness on the zoonotic helminth infections should be continuously maintained in Uzbekistan for the prevention of human infection.
