Antibiotics susceptibility of Proteus mirabilis isolated from domestic animals in Chonbuk province
Cho, Jeong-Gon ;
Korean Journal of Veterinary Service, volume 26, issue 2, 2003, Pages 95~103
Isolates of 70 Proteus mirabilis were tested against 10 different antibiotics by a disc diffusion method as recommended by National Committee for Clinical Laboratory Standards (NCCLS). The isolates were resistant in order of tetracycline(100.0%), enrofloxacin(95.7%), ampicillin(74.3%), choramphenicol(62.9%), cephalothin(58.6%), streptomycin(50%), kanamycin(47.2%), neomycin(35.8%), gentamicin(15.7%), and amikacin(2.9%). In the antibiotic resistant patterns, 37 kinds of multiple resistance patterns of P mirabilis isolates were detected. The highest resistant pattern was ampicillin-cephalothin-chloramphenicol-enrofloxacin-tetracycline(11.6%).

From February 2000 to December 2001, A total of 1,785 samples was taken from beef and pork carcasses in Seoul. Seven(0.69%) Listeria spp. were isolated from the 1,014 of beef carcasses, and five(0.65%) were isolated from the 771 of pork carcasses. The isolates were identified L monocytogenes by API listeria, and VIDAS LMO kit, serological test and PCR assay were preformed. A total 12 strains of L monocytogenes were isolated form samples tested and all of the strains were classified into serotype 1. PCR primers are selected to amplify a 520-base pair(bp) DNA fragment from the listeolysin O gene(hlyA) of Listeria monocytogenes. A 520-bp product was detected in PCR with DNA from L monocytogenes, but not from the other Listeria species tested.

This study was carried out to compare the antibiotic residues in the muscles of cattle and pigs from slaughter-houses in Seoul from 2000 to 2002 by EEC-4-plate, Charm II and HPLC methods. The results were summarized as follows; 1. Residual materials were detected from 41 samples(0.6%) by EEC-4-plate method from random sampling and 38 samples(12%) by Charm II method from directed sampling. 2. Violation rates were 0.3% by monitoring and 4.7% by surveillance program. 3. The 35 samples were classified as tetracyclines 30(86%), sulfonamides 4(11%),
-lactams 1(3%) and two samples simultaneously determined oxyteracycline plus sulfadimetoxine, and sulfamerazine plus sulfadimetoxine. 4. The highest residual concentration(ppm) of chlortetracycline, oxytetracyline, sulfamethazine, sufadimetoxine and penicillin were 0.5, 12.0, 6.4, 2.6 and 0.44, respectively.

This study was carried out to identify and investigate antimicrobial susceptibility for Mannheimuia haemolytical which is responsible for shipping fever. Samples were collected from nasal and lung of 100 adult healthy cattle which are slaughtered in Samsung meat corporation located in Incheon metropolitan city. lung lesion index have been investigated within 0-5 range according to Shewen and Willkie(Can J Vet Res 52:30-36, 1988). Eighty-seven of 100 cattle were under normal condition with 0-1 ranges. A total of 129 strains were collected from blood and tryptic soy agar. Among these strains, 100 strains were identified with Staphylococcus, Streptococcus and enterobacteria containing E coli. Biochemical and fermentation assay of arabinose, trehalose, xylose, mannose, mannitol, lactose and salicin were tested to identify with Mannheimia sp. for 7 strains shown haemolytic activity on blood agar. Five strains were identified with Mannheimia haemolytica and 2 strains were untyped. In seasonal survey, Mannheimia sp recovered from fall to winter(5 of 7) have been highly isolated rather than those from spring to summer(2 of 7). Mannheimiz haemolytica were susceptible to antibacterials tested in this study but more resistant to oxytetracycline and streptomycin.

A survey of canine heartworm(Dirofilaria immitis) infections among dogs in Daefu area was performed from February 2000 to October 2002 using a microfilarial test and an antigen test(AGEN
Canine heartworm). The infection rate of 220 dogs(96 males, 124 females) was 23.2%(51/22) by the microfilarial test, but was 23.6%(52/220) by the antigen test, revealing that 1 of 52 antigen-positive dogs were microfilaria-negative in the peripheral blood. All dogs that were microgilaria-positive were also antigen-positive. The infection rates of heartworm in dogs at the age of < 1, 1-3, 4-6, 7-11 and 12-15 years were 2.7%, 17.4%, 41.0%, 42.9% and 57.1%, respectively. Based on the fact that the antigen test is more accurate than the microfilaria test. The infection rates of heartworm in dogs by housing of indoor and outdoor were 6.9% and 46.4%, respectively. Based on the fact that outdoor housing is more infectious than indoor housing.

Fowl typhoid is a septicemic disease of turkeys and chickens. The antigen is Salmonella(S) gallinarum, which cross-reacts with S pullorum because of common antigen. The organism is maintained in the ovary of carrier birds and transmitted vertically in the york. It is also transmitted horizontally through feces and broken eggs. The symptoms are weakness, drowsiness, wing drooping, hyperexcitability, paresis and diarrhea. In the many cases, the birds are found dead in the morning before any symptoms have been noticed. this experiment was carried out to investigate the characteristics of S gallanarum and scrutinized about the control systems. 1. Fowl typhoid was came about in the winter than the other seasons. The average of mortality was 46.3%. And it was came about not only adult poultry but also chicks. 2. S gallinarum was isolated from liver and spleen in infected chickens. Total isolated strains were 60. 3. The organisms were all extinct at 60
, 30mins. 4. A survival rate was higher in underground water than a secondary distilled water. It was detected in underground water until 30 days. 5. When being exposed to the solar light, it became extinct almost within 24 hours. 6. It was survived in a refrigerator until 12 months. 7. It was extinct among 5 mins in 0.1% phenol and 2% formalin. 8. When the cultured organism fluid was inoculated in SD-rat abdominal cavity, rat died within 24 hours. 9. Pullorum-typhoid related program must disciplines in order to destroy the fowl typhoid, and breeding system must be converted to cage system.

To explore the most sensitive and useful method for simultaneous determination of 8 carbamate pesticides in livestock productions, the mixture of 8 carbonates was determined by HPLC with scanning fluorescence detector. For mobile phase water, acetonitrile and methanol program gradient showed more applicable sensitivity than water and acetonitrile program gradient used ExW 339 nm and EmW 445 nm for fluorescence detector. On using carbamate columns, the retention time was within 4 to 20 minutes. And this made it possible to separate and detect simultaneously. therefore we could analyze it exactly and efficiently and reduce time. The preparation process of MSPD method showed that the high recovery rate was more than 88.5% in most of the carbamate pesticides. Therefore we could say that it was an efficient and fast method analyzing out of lots of samples.

This study was carried out to get a fundamental information for improvement of reproductive performance in gilt. We investigated the effects of breeds on body weight, age, body length, wither's height, girth and backfat thickness, and the serum concentrations of estradiol-17
, cortisol and progesterone at first estrus and mating of gilts. A total of 47 gilts of Duroc, Landrace and Yorkshire, produced at Livestock Experiment Station, Chungnam livestock sanitation research institute from 2000 through 2002, were used for this experiment. Body weight, age and girth of Duroc at frist estrus and mating were higher than those of Landrace and Yorkshire. There were no differences on body length among the three breeds at frist and mating. Wither's height of Duroc and Yorkshire at first estrus and mating was higher than that of Landrace. Backfat thickness of Yorkshire was thinnest among the three breeds at first estrus, but there were no differences on backfat thickness among the three breeds at first mating. Serum estradiol-17
concentration of Landrace(45.0 pg/ml) at first estrus was higher than that of Yorkshire(27.4 pg/ml) and Duroc(21.8 pg/ml), but there were no differences on estradiol-17
concentration (from 18.5 to 31.9 pg/ml) among the three breeds at first mating. Serum cortisol concentration of Duroc at first esturs and mating was higher than that of Landrace and Yorkshire. There were no differences on serum progesterone concentration among the three breeds at first estrus and mating of gilt.

This stud was attempted to detect six benzimidazoles[thiabendazole(TBZ), oxfendazole(OFZ), mebendazole(MBZ), flubendazole(FLBZ), albendazole(ABZ), and febendazole(FBZ)] in eggs using high performance liquid chromatography(HPLC) with photodiode array detector(DAD) simultaneously. The eluates were determined by HPLC on a waters X-Terra
) with DAD at 295nm. The mobile phase was 0.04M ammonium phosphate(pH 7.5)/ACN(62.28 v/v) run isocratically. The calibration curves were linear(r>0.999) for six benzimidazoles. Average recovery rate from eggs were 94.54% for TBZ, 97.71% for OFZ, 88.82% for MBZ, 93.71% for FLBZ, 78.61% for ABZ, and 75.09% for FBZ, respectively. The limits of detection and quantification were 2.27ppb, 3.88 for TBZ, 9.34ppb, 15.61ppb for OFZ, 28.53ppb, 45.15ppb for MBZ, 27.39ppb, 40.95ppb for FBZ, 8.61ppb, 13.95ppb for ABZ and 12.79ppb, 22.34ppb for FBZ, respectively.

This study was conducted to survey the farm which suffered from disease similar to classical swine fever(CSF) in Gyeongbuk province. Clinical signs appeared first in a few number of growing pigs which showed specific signs of diarrhea, depression, sleepiness, and reluctance to get up or to eat. Younger piglets may have appeared chilled, shiver and huddle together. As the disease progresses the affected pig's skin went red and purple. In histopathological signs, there were many haemorrhages throughout the body and larger haemorrhages in some organs such as lymph nodes. And there is a precipitous fall in the number of circulating leukocytes in the blood. In spite of insisting of farmer which did not vaccinate to classical swine fever, significant antibody production was detected in these affected pigs at enzyme-linked immuonsorbent assay. According to the above results at first glance, these affected pig suspected with CSF in clinical signs and histopathological lesions only. Because the symptoms and post-mortem picture were very similar to CSF, these false positive results would have been dangerous to diagnostician. But by reverse transcriptase polymerase chain reaction(RT-PCR) and comparative nucleotide sequence analysis, the disease was correctly diagnosed with post-weaning multisystemic wasting syndrome(PMWS) and porcine reproductive and respiratory syndrome(PRRS) compoundly. And the antigen which were detected the lesion similar to CSF virus, was confirmed with LOM vaccine strain of CSF. In most national CSF eradication program and in countries which are free of the CSF virus, vaccination against CSF is not practiced and generally is not allowed. But now in Korea, routine vaccination is practiced because of outbreaking the CSF repeatedly. When CSF is diagnosed the whole herd and other in contact animal are slaughtered continuously.

There was a mass outbreak of death caused by transport stress and malnutrition in Japanese macaques imported from Japan at a farm stock in Korea, which were diagnosed on the ground of history taking, clinical finding, hematological examination and necropsy. Twenty eight Japanese macaques imported from Japan died suddenly from the 4th day after arrival in a farm. These animals were confined very small cages individually and lose the appetite for 10 days from shipping. Main clinical findings observed from alive Japanese macaques consisted of hypothermia and dehydration. On hematological observation for typical 4 cases showed increased erythrocytes and packed cell volume. On serum biochemical examination for 3 cases showed hypoglycemia, whereas blood urea nitrogen, aspartate aminotransferase and alanine aminotransferase were increased. On necropsy for 3 cases, hemorrhage and congestion were observed on the lung and the walls of stomach and intestine were thinned. Histologically, hemorrhagic pneumonia and enteritis with loss of villi were seen. The death of these animal was caused by poor management during transport, which was resulted in transport stress and malnutrition.
