  • A uniform group of 12 upgrade grower goats of 6.0 -7.5 months old were used in this study. They were equally divided into three groups of $T_1$, $T_2$ and $T_3$ and were infected orally with three levels (0, 5,000 and 10,000 larvae) of infective Haemonchus contortus larvae. Before infection, all animals were housed in individual pens with concrete floor. They were provided with a uniform management. Comparison of body weight changes of infected and uninfected grower goats were done using weekly body weights. There was significant (p < 0.01) interaction between the effect of stomach worm infection and duration of infection on body weight. The infected groups (2 and 3) weighed significantly (p < 0.05) less than the control group from week 18 to 21. The animals of control group gained an average of 2.85 kg with 18.75 g average daily gain (ADG) in 152 days, which were significantly higher than those of animals in the infected groups. There was significant effect of H. contortus infection on the pres laughter weights of grower goats. The hot carcass weights of the infected goats were significantly lower than the uninfected group. No significant difference in dressing percentage of infected and uninfected groups was observed.

  • Twelve newborn goat kids born of philippine does (3.5 and 5 years old) were used in this study. Four mother (candidate) doe goats were randomly allocated to each group. The mother does were infected orally with three levels (0, 15,000 and 30,000 larvae) of infective Haemonchus contortus larvae. Before infection all animals were housed in individual pens with concrete floors. They were provided with a uniform management. Estrus of does were synchronized using PGF2 alpha. All the animals were bred naturally by the same buck. Baby goat born of infected mother goats were divided into three groups. $T_1$, $T_2$ and $T_3$), respectively, from mother treatment groups. Birth weight and growth of goat kids born from H. contortus infected mother goats were determined. Birth weights of kids of $T_1$, $T_2$ and $T_3$ were 1.9, 1.5 and 1.2 kg, respectively. No significant (p > 0.05) differences in birth weight of kids for the 3 treatment groups were found. However, significant (p < 0.05) effects of stomach worm infection and duration of infection on liveweight gain of kids were observed. After second and third week of birth, respectively, the kids of groups 3 and 2 registered lover liveweight gains than the kids in control group. However, no significant (p > 0.05) difference in liveweight gain was found between the kids of infected mother does. Fecal egg counts of the infected mother does showed patent infections which also indicated by postmortem worm counts. However, no worm egg was found in the feces of the test kids.

  • A case of Pseudoterranova decipiens infection was found in a 43-year-old man by gastroendoscopic examination on August 20, 1996. On August 6, 1996, he visited a local clinic, complaining of epigastric pain two days after eating raw marine fishes. Although the symptoms were relieved soon, endoscopic examination was done for differential diagnosis. A white, live nematode larva was removed from the fundus of the stomach. The larva was $38.3{\times}1.0{\;}mm$ in size and had a cecum reaching to the mid-level of the ventriculus. A lot of transverse striations were regularly arranged on the cuticle of its body surface, but the boring tooth and mucron were not observed at both ends of the worm. The worm was identified as the 4th stage larva of P. decipiens.

  • The present study was performed to report 15 anisakiasis cases in Korea and to review the Korean cases reported in the literature. Total 32 Anisakis type I larvae were detected in the stomach of 15 patients by the endoscopy. Single worm was detected from 12 cases, and even 9 larvae were found from 2 cases. Epigastric pain was most commonly manifested in almost all cases, and hemoptysis and hematemesis were seen in 1 case each. Symptom manifestations began at 10-12 hr after eating fish in 73.3% cases. Endoscopy was performed 1-2 days after the symptom onset in most cases. The common conger, Conger myriaster, was the probable infection source in 7 cases. In the review of Korean anisakiasis cases, thus far, total 645 cases have been reported in 64 articles. Anisakis type I larva was the most frequently detected (81.3%). The favorable infection site of larvae was the stomach (82.4%). The common conger was the most probable source of human infections (38.6%). Among the total 404 cases which revealed the age and sex of patients, 185 (45.8%) were males, and the remaining 219 (54.2%) were female patients. The age prevalence was the highest in forties (34.7%). The seasonal prevalence was highest in winter (38.8%). By the present study, 15 cases of gastric anisakiasis are added as Korean cases, and some epidemiological characteristics of Korean anisakiasis were clarified.

  • Comparison of body weight changes of does infected with Haemonchus contortus (treatment groups 2 &3) and uninfected does (control group) was made using weekly body weight measurements over 35 weeks. The animals in treatment group 2 weighted significantly (p < 0.05) less than animals in the control group from the 5th week to the end of the experiment. Does in treatment group 3 had significantly (p < 0.05) lighter body weight than control does from the 13th week to the end of the study. The animals in control group gained an average of 0.75 kg. On the other hand, animals in infected groups 2 and 3 lost an average of 3.90 kg and 4.13 kg body weight, respectively. The animals in groups 2 and 3 also had significantly (p < 0.05) lower preslaughter and hot carcass weights than the controls.

  • Anisakiasis is a accidental parasitic infection caused by nematode larvae belonging to the subfamily Anisakinae when a raw or inadequately cooked fish is ingested. The common clinical symptoms are severe colicky abdominal pain or epigastric full sensation, nausea, vomiting and fever, but hematemesis or melena is very rare. We report a case of a 11-year-old female child who developed severe epigastric pain recurrently for 2 months, and recalled that she had eaten the raw flesh of an Astroconger myriaster. Endoscopic examination showed the whitish worm invading the stomach wall. Clinical symptoms disappeared after endoscopic removal. This study may be the first pediatric case of gastric anisakiasis in korea.

  • This study was performed to observe histopathological changes and serological reactions in chronic anisakiasis of rabbits. Each rabbit was infected per os with 30 larvae of Anisakis type I. Their sera were collected chronologically and the rabbits were killed for histopathological examination, 3, 13, 20, 30, 60, 90 and 150 days after the infection. The results were summarized as below. 1. Most of the larvae were recovered from the stomach, but a few from the omentum, intestine, mesentery and abdominal wall. The recovery rates and distribution of worms by organ were not differed by duration of infection. 2. Histologically the lesion was abscess type on 13 days, i.e., the dead worms were surrounded by fibrinous exudate, histiocytes and thick zone of numerous inflammatory cells. After 30 days, histiocytes were found to invade the worms and the lesion was changing into abscessgranulomatous type. Also a calcified worm was found on the 30th day. After then the worms were observed to be dissolved slowly until 90 days. On 150 day, only one calcified worm was observed. 3. The levels of serum IgG antibody by ELISA reached their maximum 30 days after the infection. After then, it decreased slowly until 150 days after the infection. Above serological and histopathological findings indicated that antigenic stimulation from degenerating Anisakis larvae was the greatest during the first 30 days after infection. This period was corresponding with the beginning of worm resolution or calcification. Serologic test by ELISA would be a valuable tool for confirming chronic anisakiasis.

  • Korean native goats were used for meat production test, and summarized resalts are as follows. 1. The amounts of feed consumed for Korean Native Goat were significantly higher at day than at night. 2. The feed intake was decreased and live weight gain was lower for the summer period. 3. The concentrate consumption was increased when poor quality of pasture and native grass. 4. Compared between single bran feeding group$(T_2)$ and mixed grain feeding group$(T_3)$, the roughage consumption were similar in both groups. 5. By the use of feeding standard for feeding of Korean Native Goat, the feed convertion of T.D.N, D.C.P, and M. E were decreased. 6. It is necessary to periodically protect from contamination parasitic such like stomach worm, liver flack, nodula worm disease and coccidiosis. 7. The carcass rates of goat at 11-12 months age were higher in $T_3$ feeding group as 44.56% compared with $T_2$ feeding group as 42.17% and tethering group as 35.1% and also the dressed carcass percentage were 33.89%, 30.25% and 29.92% respectively. 8. By increasing the amouat concentrate feeds, fat content in muscle was increased but moisture and ash contents were decreased. 9. The fat caused unacceptable flavour was about 4 percent of total dressed goat meat. 10. Among the spices, clove and pepper were better to improved meat flavour for sausage and can meat processing 11. It was known that the quality of goat meat was suitable for meat processing.

  • Chromosomes of gonadal tissues from Fasciola spp, Eurytrema pancreaticum and Calicophoron calicophorum occurred Korean cattle were egamined using modified air-drying method. To compare their phenotype with three different genotypes among Fasciola spp, the adult and egg si2e were measured since they have been known as important taxonomical characters. The results obtained were as followed; Cattle liver fluke, Fasciola spp were classified into three types based on their chromosomal complements such as individual with 2o chromosome(diploid), 30 chromosome(triploid) and 20/30 mosaic constitution(mixoploid). The propotions of appearance of three types were 40.00%, 54.29% and 5.71%, respectively. The frequency of three types in type I which was regarded as F gigantica were 58.82% for diploid, 35.29% for triploid and 5.88% for mixoploid, but in type II which was regarded as F hepatica were 72.2% for triploid, 22.22% for diploid and 5.56% for mixoploid. Egg length of triploid forms was significantly larger than that of diploid forms and egg size of mixoploid forms was similiar to that of triploid forms. Worm size of triploid forms was larger than that of diploid forms and was more similar to that of mixoploid forms, but the statistical data were not significant. Diploid chromosome consisted of one pair of metacentric chromosome(m), four pairs of submetacentric chromosomes(sm), five pairs of subtelocentric chromosomes(st), while triploid chromosome consisted of one pair of metacentric chromosome, seven pairs of submetacen.tric chromosomes, one pair of subtelocentric chromosome and telocentric chromosome(t), respectively. In mixoploid chromosome, constitution of the chromosomes of diploid or triploid cell was consistent with that of diploid or triploid. Chromosomes of gonadal tissues from pancreatic fluke, Eurytrema pancreaticum consisted of 13 pairs of homologs(2n=26, n=13). The mitotic and meiotic divisions were observed frequently. In the mitotic metaphase, Karyotype consisted of five pairs of metacentric chromosomes, four pairs of submetacentric chromosomes, three pairs of subtelocentric chromosomes and one pair of telocentric chromosome. Chromosomes of gonadal tissues from stomach fluke, Calicvphoron calicophorum consisted of 9 pairs of homologs(2n=18, n=9). The meiotic divisions was frequently observed, but mitotic divisions was rare. In the mitotic metaphase, Karyotype consisted of two pairs of metacentric chromosomes, three pairs of submetacentric chromosomes and four pairs of subtelocentric chromosomes. Karyotype of Calicophoron calicophorum differed from that of Japanese C calicophorum which was similar to that of Paramphistomum cervi of Korean cattle. Though that of Calicophoron calicophorum of Korean cattle was similar to that of Paramphistomum explanatum of Korean cattle, that have been recognized to be a different species of fluke.
