摘要:

An outbreak of coccidiosis on two Belgian farms is described. Diarrhea started in piglets at 9 or 10 days of life. Zero to three pigs died per litter. The morbidity rate varied from 70 to 90 per cent. Histological examination of the intestines revealed shortening of villi and different stages of the life cycle of coccidia were seen in the enterocytes. Virological examination was negative for corona‐, corona‐like, and rota‐virus. A haemolytic E. coli strain was isolated in one case. As for treatment, good results were obtained by the adding of 1 kg amproleum pre‐mix per ton sow feed. Scouring pigs were treated orally with 2 cc of an amprol solution once a day. The diarrhea stopped one day after treatment.

摘要:

The eyes of 160 Collies were examined for Collie Eye Anomaly, Progressive Retinal Atrophy, and any other eye abnormality present. The incidence of CEA in 160 Collies was 40.6 per cent.

摘要:

The comparative efficacy of a product containing 500 mg benzathine cloxacillin (Orbenin D.C.), another product containing 100 mg nafcillin, 300 mg procaine benzylpenicillin and 100 mg dihydrostreptomycin (Nafpenzal D.C.) and a third product containing 250 mg cephalonium (Cepravin D. C.), in the elimination and prevention of mastitis due to gram‐positive microorganisms during the dry period was investigated in 1253 cows located in 14 herds in Israël.

摘要:

Influenza virus A‐equi 2 (Heq2Neq2) caused an epizootic in the Netherlands in the winter of 1978–1979. Horses vaccinated with A / Equi / Praha/56 (Heq1 Neq1) and A/Equi/ Miami /63 (Heq2Neq2) were also infected and showed clinical signs. The virus involved showed a marked antigenic drift from the prototype and vaccine strain A/ Equi/ Miami/63 (Heq2Neq2).

摘要:

A review is presented of the phagocytosis and intracellular killing of Staphylococcus aureus by polymorphonuclear and mononuclear leukocytes. Recruitment of adequate numbers of leukocytes to the site of infection occurs through the process of chemotaxis. Recognition of invading staphylococci by the phagocytic cells is mediated through bacterial opsonization. Both processess depend upon the activation of the heat‐labile complement system which generates the majority of chemotactic (C5a) and opsonic (C3b) molecules for S. aureus phagocytosis. The key role of peptidoglycan in the cell wall of staphylococci in these events is stressed. Attachment and ingestion of opsonized staphylococci occurs via poorly‐defined receptors for opsonins in the membrane of the leukocyte. The greater phagocytic capacity of neutrophils as compared to monocytes is not reflected in differences in their membrane receptors for staphylococcal opsonins. Once ingested, staphylococci are rapidly destroyed by oxygen‐dependent and oxygen‐independent bactericidal mechanisms of the phagocytes. Small numbers of S. aureus may survive within the leukocyte. Special attention is focused on the numerous ways S. aureus is able to hinder, evade, and directly damage the phagocytic defense mechanisms of the host.

摘要:

In a four‐year survey, the course of pasture infestation with infective larvae of Strongylidae and the pattern of development of the Strongylidae infection in the host were investigated. In this way it was hoped to obtain epidemiological data which might serve as a basis for the control of strongylidosis in the horse.
