In 1972, cysts of Echinococcus multilocularis were observed in two adult Peromyscus maniculatus trapped within 1.8 km of Lethbridge, Alberta. These findings extended the known distribution of this parasite in Alberta and in southwestern Canada.

Larval Echinococcus multilocularis was found in one of 25 Peromyscus maniculatus collected in a dolomite quarry near Gunton, about 30 miles north of Winnipeg. This finding shows that E. multilocularis is present in Manitoban rodents at least in an area of 60 sq. mi.

Cysts of Echinococcus multilocularis Leuck. 1863 were found in 15 of 99 deer mice, Peromyscus maniculatus (Wagner), from a dolomite quarry and a gravel pit 12 and 20 miles north northeast of Winnipeg respectively, in the Stony Mountain – Argyle area. This is the first report on the occurrence of E. multilocularis in Manitoba rodents. It extends northeast the known area of distribution of this cestode in the North American prairies.

Echinococcus multilocularis Leuckart, 1863 has been recovered from 63 of 283 Peromyscus maniculatus trapped near Edmonton, Alberta. This record extends the known distribution of Echinococcus multilocularis in central North America to the northwestern edge of the prairie and into the aspen parkland zone.

Wheat spot mosaic disease was first discovered in southern Alberta, Canada, in 1956. A hitherto unidentified disease-causing agent, transmitted by the eriophyid mite, caused chlorosis, stunting and finally severe necrosis resulting in the death of the affected plants. Double membrane-bound bodies (DMBB), 0.1-0.2 μm in diameter were found to be associated with the disease.Young tissues of leaf and root from 4-wk-old infected wheat plants were fixed, dehydrated, and embedded in Spurr’s resin. Serial sections were collected on slot copper grids and stained. The thin sections were then examined with a Hitachi H-7000 TEM at 75 kV. The membrane structure of the DMBBs was studied by numbering them individually and tracing along the sections to see any physical connection with endoplasmic reticulum (ER) membranes. For high resolution scanning EM, a modification of Tanaka’s method was used. The specimens were examined with a Hitachi Model S-570 SEM in its high resolution mode at 20 kV.

Therapeutic Procedures

Introduction: Alveolar echinococcosis (AE) is a zoonosis caused by Echinococcus multilocularis. AE is primarily localised in the liver. Echinococcus multilocularis imitates tumour-like behaviour. It can metastasise through blood or lymphatic system to distant organs. Echinococcosis often remains asymptomatic due to its long incubation period and indistinct symptoms. Clinical symptoms are determined by the parasite’s location. Diagnosis of echinococcosis is based on medical history, clinical symptoms, laboratory tests, serology results, imaging methods and final histology findings. Surgical removal of the cyst with a safety margin, followed by chemotherapy is the therapeutic method of choice. Case report: We present a case report of alveolar echinococcosis in a thirty-year-old female patient in whom we surgically removed multiple liver foci of alveolar echinococcosis. The disease recurred after two years and required another surgical intervention. Conclusions: Alveolar echinococcosis is a disease with a high potential for a complete cure provided that it is diagnosed early and that the recommended therapeutic procedures are strictly adhered to.
