Chronic debilitation and anemia were observed in a free-living opossum (Didelphis marsupialis) heavily parasitized by Physaloptera turgida, Brachylaima virginianum, and Cruzia americana. Chronic interstitial pneumonia associated with Capillaria aerophila and a metastrongyloid nematode also was present.
Gastrointestinal and bronchopulmonary nematode infections and the efficacy of netobimin (Hapasil) were analyzed by way of fecal examination in 10 female mouflons (Ovis musimon), in central Spain, February 1993. Before treatment all 10 mouflons had Trichostrongylus axei, Teladorsagia circumcincta and Marshallagia spp.; sic had Nematodirus spp., two had Trichuris sp., one had Capillaria sp., seven had bronchopulmonary Dictyocaulus filaria and 10 mouflons had protostrongylid lungworms (Muellerius capillaris, Protostrongylus rufescens, Cystocaulus ocreatus or Neostrongylus linearis). Netobimin (7.5 mg/kg) was 100% effective against T. axei, T. circumcincta, Marshallagia spp., and D. filaria infections whereas one animal continued eliminating Nematodirus spp. eggs. The drug also was effective against Capillaria spp. but not against Trichuris spp. or protostrongylid infections.

We report a case of porocephalosis in a 35-year-old Congolese adult who habitually ate large amounts of snake. The principal nonspecific clinical sign was abdominal pain. Diagnosis was based on X-ray examination of the abdomen without preparation and abdominal ultrasound scan.

A 32 year old male, positive for human immunodeficiency virus (mY) antibodies, was found to be positive for multiple opportunistic infections by a parasite and a fungi, which is a very rare occurrence. Cryptosporidium and Geotrichum were simultaneously detected from his stool and sputum respectively.
The efficacy of netobimin against digestive tract strongyles and the small lungworm Muellerius capillaris was tested in a dairy goat herd. The drenches were given orally at the rate of 20 mg/kg of body weight once, 10 mg/kg on 2 successive days, or 7.5 mg/kg on 3 successive days. Fecal egg counts and larval counts were done 8 days before and on the day of drenching; further counts were performed on postdrenching days 8 and 18. Two goats were necropsied, 1 on postdrenching day 5 and 1 on day 10 in the group treated on 3 successive days. The fecal egg counts were reduced by 44 to 79% depending on dosage on postdrenching day 18; the remaining worms were Trichostrongylus colubriformis. The larval counts of M capillaris were reduced by 72 to 92%, depending on dose. The reduction was significant in all the treated groups, compared with that in the control group. The use of netobimin at the dosage of 10 mg/kg given on 2 successive days or 7.5 mg/kg given on 3 successive days might be recommended to treat goats infected with Muellerius spp and digestive tract strongyles.

During 1974-1984, cryptosporidiosis was diagnosed in slightly more than 1% (63/6050 = 1.04%) of histopathology reports on chickens and turkeys made at two Georgia diagnostic laboratories. During 1985-1988, cryptosporidiosis was diagnosed in almost 6% (157/2622 = 5.99%) of histopathology reports on chickens and turkeys made at the two laboratories. Intestinal and respiratory Cryptosporidium sp. infections have increased significantly (p less than 0.01) with time. During the same period, there was no statistical pattern for bursa of Fabricius Cryptosporidium sp. infections, and there was no relationship between the incidence of bursal infections and the incidence of either respiratory or intestinal infections.
Cryptosporidiosis is a coccidial protozoan initially reported in domestic animals. It is primarily a gastrointestinal organism that does not invade mucosa. It was first described in 1976 in developing countries as an etiology of infantile diarrhea with inanition and malnutrition. Gastrointestinal involvement in patients with AIDS has been increasingly reported. We report a case of combined gastrointestinal and bronchial cryptosporidiosis. Cryptosporidium is an acid-fast organism which was successfully treated with erythromycin.

Standard textbooks discuss parasitic disease according to specific organisms. In contrast, patients with parasitic infections present to physicians with a variety of clinical manifestations that may involve any of several organ systems and that often mimic nonparasitic diseases. A syndromic approach to the clinical situation may help the physician in considering the most important parasitic agents. Many parasitic infections can be acquired in temperate climates. While often considered tropical or exotic, other parasitic diseases are now seen more frequently in developed countries because of immigration and increased world travel. In this review the clinical syndromes associated with common parasitic diseases in North America are discussed, with an emphasis on risk factors and diagnosis of specific infections.
