Approximately 90% of freshly imported macaques and other Old World Monkeys are known to be infected with respiratory mites. The lung associated pigments are integral components of pulmonary acariasis in Old World Monkeys; at least three distinctive pigmental bodies are identified in association with lung mite infection. Two major components of pigments are recently identified as silica by using elemental analysis using a high voltage electron microscope and an energy-dispersive X-ray analysis technique. Since a limited number of infected monkey lung tissues and associated pigments can be examined by this tedious procedure, it was important for us to examine much greater number of specimens to verify our initial observation. Ten microincineration technique described provided a unique and practical way to identify the mineral elements in as many 27 histologic sections within a short span of time. Silica and silicates are heat resistant whereas majority of organic materials including lung mite parasites disintegrated under the extreme temperature. Mineral elements were exclusively located within the polarizable white ash. More than 90% of total pigmental bodies identified were found to be related to siliceous materials in 20 incinerated infected monkey lung tissues whereas five noninfected lungs similarly examined did not reveal any pigmental bodies. Other than a small of fine granular mucin substances which were PAS positive, the majority of lung mite associated pigments such as large granules of hemosiderin, needle-like crystals and other fine granules engulfed by macrophages were identified to be siliceous materials as they have persisted even after microincineration. Mite parasites and other organic materials were completely disintegrated. Similar pigmental bodies examined by microscope X-ray analysis were positive for silicate. This finding suggests that lung mite infection in Old Monkeys apparently predisposed silicosis. Therefore, until the link between lung mite infection and silicosis is clarified, expreimental inhalation toxicologic findings in mite-infected Old World monkeys should be interpreted cautiously.

Human infections with Lophomonas blattarum are rare. However, the majority of the infections occurred in China, 94.4% (136 cases) of all cases in the world. This infection is difficult to differentiate from other pulmonary infections with similar symptoms. Here we reported a case of L. blattarum infection confirmed by bronchoalveolar lavage fluid smear on the microscopic observations. The patient was a 21-year-old female college student. The previous case which occurred in Chongqing was 20 years ago. We briefly reviewed on this infection reported in the world during the recent 20 years. The epidemiological characteristics, possible diagnostic basis, and treatment of this disease is discussed in order to provide a better understanding of recognition, diagnosis, and treatment of L. blattarum infection.

A patient with multiple-organ echinococcosis suffered from liver echinococcosis,lung echinococcosis,and pelvic echinococcosis successively in the past three decades.From the first operation at 19 years-old,she underwent operations several times due to the recurrence of multiple organ involvement.Echinococcosis is a zoonotic disease.Although the liver usually is the primary site,the disease can also invade many other organs.Diagnosis is typically based on disease history and imaging findings.Thorough removal of the lesions during the first operation is particularly important.Comprehensive evaluations and multi-disciplinary team are helpful in the treatment of patients with multiple organ invasion.

Clinical manifestations of extralymphatic disease caused by filariasis are varied and range from symptoms due to tropical pulmonary eosinophilia to hematuria, proteinuria, splenomegaly, and rarely arthritis. Disseminated microfilaremia in association with loculated lung cyst and empyema is of rare occurrence and to the best of our knowledge has not been documented in the literature so far. We report here a case of disseminated microfilaremia due to Wuchereria bancrofti infection accompanied by a lung cyst and empyema in a 21-year-old Indian man.

Total 9 cases of extraintestinal amoebiasis, amebic liver abscess and amebic lung abscess, were treated with metronidazole. The diagnosis and progress check were done by (1) stool examination, (2) size and pain of liver, (3) hematological examination, (4) urinanalysis, (5) X-ray or liver scanning (6) examination of aspirated pus from liver and (7) immobilization test of E. histolytica. Results are summarized as follows: Amebic hepatitis: Metronidazole was given to 3 cases with daily dose of 0.9-1.2 gm for 3-7 days. Clinical symptoms were completely restored by the treatment. Amebic lung abscess: One case was treated with metronidazole for 3 days with the daily dose 1.2 gm. X-ray findings showed remarkable improvement by the treatment. An additional administration of the drug for 6 days resulted complete resolution of the pneumonic changes. Amebic liver abscess: Four cases were treated with metronidazole. The daily doses were 0.4-2.4 gm and continued for 2-10 days. Aspiration of the abscess for 1-10 times or continuous drainage of pus were performed during the course supplementarily. All cases were recovered to normal by the combining treatment. No remarkable side effect was noticed by the drug administration, and no relapse was experienced up to date.

OBJECTIVESTo determine the natural crustacean host, the Paragonimus species, and to investigate the potential host-parasite relationship between Manipur Paragonimus and some of the laboratory animals.

METHODSThe laboratory animals such as puppies, albino rats and Swiss mice were infected orally with metacercariae isolated from the fresh water crabs, Potamiscus manipurensis. The fecal specimens of the experimentally infected animals were examined microscopically for Paragonimus eggs at regular intervals. The animals were autopsied on days 35 to approximately 328 after infection and the isolated worms were flattened between glass slides and fixed in 70% alcohol. The worms were stained with carmine and mounted with Canada balsam for morphological studies. The eggs were collected in 5% formol saline solution for microscopy. The flukes were classified into 4 developmental stages.

RESULTSA total of 11 worms, 5 mature, 5 immature and 1 pre-adult were recovered. The morphological features of the metacercariae, worms and eggs were similar to those of Paragonimus heterotremus.

CONCLUSIONManipur is one of the rare areas in the world where Paragonimus heterotremus is prevalent and the puppies are ideal experimental animal host. This species may be one of the important causes of paragonimiasis in animals and humans in Manipur.
