Muscle tissue from the oesophagus and diaphragm of 500 beef cattle slaughtered in New Zealand was examined for Sarcocystis infection by microscopic examination of cysts isolated from muscle samples. All cattle were infected with Sarcocystis; based on light microscopy of cysts, 98% had thin-walled Sarcocystis cruzi cysts and 79.8% had thick-walled(More)
Ten Eimeria field isolates from North Germany were studied in battery tests for sensitivity to selected anticoccidials. A high percentage of the Eimeria field isolates (9 out of 10) showed resistance to anticoccidials, mostly multiple resistance. Partial or complete resistance to maduramicin was found in 7 field isolates, to monensin in 6, to salinomycin in(More)
OBJECTIVE One of the aims of a subcutaneous (SC) injection is to avoid intradermal or intramuscular injections. Pen systems are an alternative solution to single-use syringes and have become standard for example diabetes therapy. Shorter and smaller needles minimize pain and the risk of intramuscular injections. The thickness of subcutaneous adipose tissue(More)
Anti-Toxoplasma antibody titres in 185 sera from clinically normal goats from 14 farms were assayed by both the latex agglutination and the indirect fluorescent antibody tests. The animals were of various breeds including Angora, New Zealand feral, Angora x feral, Saanen and Toggenburg. A high level of agreement between the two tests was obtained with 83.8%(More)
Two recombinant Toxoplasma gondii polypeptides, H4 and H11, were tested as diagnostic antigens in enzyme-linked immunosorbent assays (ELISAs). The results obtained by ELISAs based on single H4 (H4-ELISA), on single H11 (H11-ELISA) and on a mixture of H4 and H11 (H4/H11-ELISA) were compared with results obtained by an ELISA based on traditional ELISA antigen(More)
A total of 482 serum samples from pastoral camels in the Butana plains, mid-Eastern Sudan, were tested for Toxoplasma antibodies by the latex agglutination test (LAT). Sixty-seven percent of the camels were seroreactive. The prevalence rate of seroreactivity increased significantly with age (P less than 0.01) and was highest among camels aged over 7 years(More)
Bartonella henselae and B. quintana infections in man are associated with various clinical manifestations including cat-scratch disease, bacillary angiomatosis and bacteraemia. While cats are the natural reservoir for B. henselae, the source of B. quintana is unclear. In this study, the sera of 713 cats from Germany were examined for the presence of(More)
From July 1993 to June 1994 2036 fecal samples from 196 litters from 10 pig farms were collected. Three or four piglets from each litter and the respective sows were examined 3 times at 2, 3 and 4 weeks after farrowing. I. suis was detected in all 10 farms. The rate of infection of the litters was 62.2%. 71.6% of all litters with diarrheic problems were I.(More)
Following oral infection of Microtus agrestis with sporocysts of Frenkelia microti, transient focal necrosis and cellular infiltrations in the liver, hyperplasia of lymphoid organs, and inflammatory infiltrations in the heart, pulmonary veins, skeletal muscles and brain occurred during the first asexual multiplication period of the parasite in the liver.(More)
Twelve anticoccidial or antimalarial drugs were tested for their efficacy against various development stages of Sarcocystis muris in NMRI-mice. Schizogonic stages present in the liver from day 11 to 17 p.i. showed to be most sensitive to drug action. Sulfaquinoxaline plus pyrimethamine, zoalene and Bay g 7183 completely eliminated these stages. A strong(More)
