This concerns the summary report of a series of studies on Metastrongylosis hitherto published by the writer. The life cycle of swine lungworm was first elucidated by Hobmaier in 1929. Since then subsequent studies conducted by many workers have revealed that some species of earthworms act as specific intermediate hosts of swine lungworm. The writer observed that three species of earthworms, Helodrilus foetidus, Allolobophora caliginosa and Pheretima, serve as intermediate hosts of swine lungworm in Korea. The present summary consists of the results of survey on the distribution of infectious lungworm larvae and the studies on the developmental growth of lungworm larvae in the intermediate and terminal hosts.

This experiment was undertaken in order to investigate whether chicken can serve as a carrier for swine lungworm, Metastrongylus apri. The results abtained are summerized as follows: All chickens which were fed the infective larvae of M. apri, in the form of infected earthworm (Eisenia foctida) excreted appreximately 4.4 to 5.4 percent of the infective larvae in their feces between 2 to 10 hours after dosing. The larval excretion was marked especially during the first 2 hours. A few (0.10~0.12%) larvae were detected from the intestinal wall of chickens by pepsin-digestion method on a day after dosing, but no further migration or development of the larvae was observed. The larvae which had passed through the digestive tract of chickens retained their viability and produced characteristic lungworm disease when inoculated to guineapigs. From these results, it may he concluded that the chicken can serve as a carrier for the infective larvae of M. apri.

Case 1 was showed severe caughing and nasal discharge, who was one of 5-month-old 18 male sheep taking inspection for MCF experiment. Pathological examination of case 1 was conducted. Macroscopic observations were the foamy sticky fluids in nasal and tracheal cavity, the grey spots with 2-4 mm diameter on the surface of lung. Histopathological observations were severe eosinophil and other round cell infiltration in general organs including lung, trachea, small intestine, large intestine, liver. Also, in the lung, there were parasite-cutting lesions in some alveolar spaces and bronchioles. Following these observations, case 1 was diagnosed as ovine lungworm infection.

본 연구는 서해안 새만금 방조제 내만에서 발견된 상괭이의 기생충 감염 사례 보고이다. 상괭이는 수컷으로 연령이 8세로 추정되었다. 기생충은 복강, 두개골 및 폐 등 총 3개 기관에서 3종류가 발견되었다. 복강내 선충은 Crassicauda sp.으로 추정되었다. 두개골내 흡충은 Nasitrema sp., 선충은 Pseudaliids 과에 속하는 폐충의 일종일 것으로 추정되었고 폐충은 폐 조직표본 현미경 검사에서도 발견되었다. 아니사키스 (Anisakis spp.) 는 발견되지 않았다.

1. Of 4,112 earth worms, 3,480 were classified as Eisenia foetidae, and 3,277 of the species were infested with the larvae of Metastrongylus apri. 2. Cresol and $CaCN_2$ were found effective in the insecticidal test of earthworms. 3. The nose ring was effective, in pigs, to prevent digging and eating the earthworms and resulted a lower lungworm incidence in pigs. 4. The best place to put the nose ring was the nasal septum.

A male, 3.5 month old Pomeranian dog was diagnosed with a natural infection of Crenosoma (C.) vulpis in Daejeon, Korea. First stage larvae of C. vulpis were detected by fecal examination using the Baermann technique. Thoracic radiographs revealed mild, pervasive bronchial infiltration of the lung. Enumeration of larvae via the McMaster technique revealed 1,600 larvae per gram of feces. The dog was treated with mebendazole, and clinical symptoms were resolved 2 weeks post-treatment, as indicated by the subject presenting fecal tests negative for C. vulpis.

Pathological studies, on the lung of 27 cases of bovine parasitic bronchitis which were secured from abattoirs in Korea, were performed and discussed. The chief pathological findings were as follows. Grossly, the lungs were shown various degree of lobular consolidation, collapse and alveolar emphysema around the bronchi in which nematodes of Dictyocaulus viviparus were present. Emphysema and edema were observed in the interlobular septa. The lesions were encountered mostly in the caudal and ventral borders of the diaphragmatic lobes. In all the cased of parasitic bronchitis in which thickening of the visceral pleura and fibrinous deposition on the pleural surfaces were not seemed to be entirely due to the lungworm infection. Microscopically, bronchopneumonia, peribronchial and peribronchiolar lymphoid hyperplasia, lympho-reticular broncho-occlusive legion, and bleakthrough lesion were examined in the affected lungs.

In a pasture located at Kyong Puk area, a group of 200 Korean native casttle showed severe coughing, dyspnea and emaciation, of which 30 cattle died from the respiratory disease. To the alived cattle, clinical, pathologicoparasitological observations and treatment with terramycin, Mintic and tetramisole (Bonasol) were carried out and the following results were obtained. 1) Paroxymal coughighings, increased respiratory rate and heart rate were observed in almost all cases. But, larval output in feces was recognized in 32 percent of the cases. 2) Morderate eosinophilia was observed in a half of the cases. 3) At autopsy, lungs were enlarged, and areas of dark consolidations were scattered in all lobes. In the bronchi, numerous adult lungworms were found. 4) The adult worms detected from the bronchi were morphologically identified as Dictyocaulus viviparus. 5) The clinical signs and larval output were disappeared after the administration of Mintic or Bonasol. 6) From these results, it was concluded that the respiratory disease of the cattle was caused by the infestation of lungworm, Dictyocaulus viviparus.

In a cross-sectional abattoir survey of bovine pulmonary diseases in Mymensingh, during September 2001 to April 2002, subclinical Dictyocaulus viviparous infection was found in mesoendemic level in Bangladeshi adult zebu cattle. The number of mature lung worms varied from $1{\sim}18$ in individual lungs. One to five mature lung worms were most frequent (74.2%) followed by 6 to 10(19.3%) and $11{\sim}18$ (6.5%). Of the total 123 mature worms collected from 31 lungs, there were 50 (40.7%) male and 73 (59.3%) female worms. The female lungworms (mean length 14.41mm) were significantly (P<0.01) larger than the male lungworms (mean length 11.28mm). The number of hydatid cysts varied from $1{\sim}80$ in individual lungs. One to five ($1{\sim}5$) cysts were recorded most commonly (76.0%) followed by $11{\sim}80$ (20.0%) and $6{\sim}10$ (4%). The size (diameter) of the hydatid cysts ranged from $2{\sim}12cm$. Of the total 203 hydatid cysts collected from 31 lungs 45 (22.2%) cysts were fertile and 158 (77.8%) cyst were sterile.
