In order to detection of the intestinal parasites, 503 fecal samples were taken from mongorel-and pad-dogs in Chonbuk province. The prevalence and identification of intestinal parasites were determined by the fecal examinations using the floatation and /or sedimentation methods and microscopical examination, respectively. The results were obtained as follows; 1. Fifty-nine percent(297 dogs) from 503 fecal samples were detected eggs. In seasonal detection rate of eggs, summer was 30.3%, Autumn 26.4%, Winter 22.3% and Spring 21.0%, in order. 2. A total of 20 kinds of eggs were isolated from feces, and it was identified 75.7% as Nematoda(320 dogs), 5.6% as Cestoda(24 dogs) and 1.4% as Trematoda(6 dogs), and 17.2% as Protozoa(73 dogs). The isolates were identified as Ancylostoma caninum(30.4%, 153 dogs), Isospora spp.(14.3%, 72 dogs), Toxocara canis(11.1%, 56 dogs), Toxascaris leonina(5.8%, 29 dogs), Uncinerza stenocephala or Physaloptera spp.(5.4%, 27 dogs), Trichuris vulpis(2.4%, 12 dogs) and the others, single or in combination. 3. In mixed infection such as single, double, triple and quadraple was 63.6%, 31.7%, 3.4% and 1.3%, respectively.
This study was carried out to isolate of causative agents from CMT-positive and mean somatic cell count(SCC) >=500,000 cells/ml mastitic milk, and evaluate to antimicrobial susceptibility of isolates in Iksan branch area from January to November, 1996. 1. The CMT-positivity(SCC 500,000 cells/ml) of 610 heads was 36.2%(221), and of 2,373 quarter milks was 16.1%(383). 2. The Gram-positive isolates were 153 strains which was Staphylococcus sp(115), Micrococcus sp(18), Streptococcus sp(10), Listeria monocytogenes(5) and Enterococcus faecalis(5). 3. The Gram-negative isolates were 66 strains including E coli(14), Yersinia sp(13), Shigella sp(8), Enterobacillus sp(8), Cedecea sp(5), Pseudomonas aeruginosa(5), Proteus sp(5), Klebsiella sp(4), Salmonella sp(2), Kluyvera ascorbata(1) and Tatumella Ptyseos(1). 4. The Gram positive strains of isolates were moderately susceptible to T/s, Cp, Pd, Imp, Aug, Rif, Cft and Va. And the Gram negative strains of isolates were moderately susceptible to T/s, Cp, Imp, Pi and Ti, in order.5. Multiple antimicrobial resistant patterns were encountered 62 and 36 from Gram positive and negative isolates, respectively.

The purposes of this study were to characterize the disposition of sulfathiazole(ST) and to investigate the effects of sodium bicarbonate on the disposition of ST in broiler chicks(2.5~3.0kg). Animals were given ST acutely(10~80mg/kg, PO), and plasma, kidney, muscle, heart, liver and spleen samples were collected and analyzed for ST by high performance liquid chromatography. The plasma and tissue data was consistent with a one-compartment pharmacokinetic model. The drug is rapidly but incompletely(2.5~3.87%) absorbed with peak plasma and tissue levels being achieved within one hour after dosing. The plasma and tissue levels depended on drug dosage, and the descending order in concentration of ST was kidney>plasma>heart>muscle≥spleen≥liver from animals sacrificed at one hour after dosing. Moreover, significant positive correlations(r>0.9) existed between plasma and tissue levels of ST. In addition, sodium bicarbonate pretreatment decreased plasma level, indicating that an alkalinization stimulate the excretion of ST. Results of this study suggest that oral application of ST was rapidly absorbed and eliminated, and confirmed that tissue residues of ST can be estimated from plasma drug concentration in broiler chicks.
