Investigation of residual levels and pertaining detection wavelength of 5 sulfonamides in the mouse muscle
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 379~383
This survey was carried out to determine 5 residual sulfonamides(sulfamerazine : SMR, sulfamethazine : SMT, sulfamonomethoxine : SMM:, sulfadimethoxine : SDM, sulfaquinoxaline : SQX) in muscle of mouse. For this investigation, pertaining detection wavelength, residual levels and residual times in muscle of mouse were summarized as follows ; 1. Pertaining detection wavelength of 5 residual sulfonamides(SMR, SMT, SMM, SDM, SQX) was 270nm by HPLC/UV detection. 2. After 1 day put a stop to sulfonamides administration, residual levels was 1∼l.5ppm, but were not detected at day 7 3. Withdrawal time of 5 sulfonamides were about 7 days suspectly.
Outbreak of Eimeria stiedae infection in a rabbit farm in Kwangju
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 385~390
A rabbit farm reared about 500 New Zealand White in Kwangju city was occurred Eimeria stiedae infection. Morbidity and cumulative mortality were more than 39% and 14%, respectively, from May, 1997 to March, 1998. Most of cases with severe diarrhea were belong to younger than 2-month old. In necrospy, there were multifocally white nodules with about 1-5mm in diameter on the liver surface and dark greenish mucous exudate in intestinal lumen. Main microscopic lesions included marked hyperplasia of the bile duct epitheilia containing different developmental stages of Eimeria stiedae and inflammatory cell infiltration, and the degeneration of small intestinal epithelia. Many oocysts of Eimeria stiedae were detected in the intestinal contents and epithelia, the feces, the bile juice, the bile duct and the liver.
Prevalence of intestinal parasites of pet dogs in Taejon city
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 391~400
In order to survey the prevalence of intestinal parasites in dogs, 304 fecal samples were taken from dogs in Taejon city, The prevalence and identification of intestinal parasites were determined by the fecal examinations using sheather's floating technique and sedimentation methods and then Cryptosporidium oocysts were identified by kinyoun's modified acid fast stainning method. The results were obtained as follows ; 1. Parasite eggs and oocysts were detected in 105 samples (34.5%) from 304 cases of dog feces. 2. The 11 kinds of eggs and oocysts were isolated from the feces of dog. Those were Ancylostoma caninum (12.1%, 37 dogs), Trichuris vulpis (11.5%, 35 dogs), Toxocara canis (10.2%, 31 dogs), Isospora sp (7.2%, 22 dogs), Cryptosporidium sp (3.6%, 11 dogs), Toxascaris leonine (1.9%, 6 dogs), Strongyloides sp (1.9%, 6 dogs), Taenia sp (0.6%, 2 dogs), Diphylidium caninum (0.3%, 1 dog), Spirometra sp (0.3%, 1 dog) and Clonorchis sinensis (0.3%, 1 dog). 3. It was mixed infection such as single, double, triple and quadruple, 64.8%, 25.7%, 8.6% and 0.9%, respectively. 4. In indiviually-raised 4095, the infectious late of T canis (11.4%), A Caninum(13.2%), Cryptosporidium sp (6.1%), T leontna (2.6%) were higher than those of group raised dogs. But the infectious rate of T vulpis (12.1%) in group raised dogs was higher than that of individually-raised dogs. 5. Adults of Demodex and Sarcoptes which have been found in this survey are excluded in this report.
Uncinaria infection in a Badger, A case report
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 401~405
A male badger which showed depression and bloody diarrhea was submitted to Iksan Branch of Chonbuk Veterinary Service Laboratory for necropsy on May 1998. Grossly, paleness of the mucous membranes was observed and the small intestinal contents were hamorrhagic. The numerous tiny hookworms, sized in 5-10 mm and greyish-white in color, attached to the intestinal mucosa. Male bursa was well developed. Histologically, intestinal lumen was filled with hemorrhagic contents, which contained worms. The epithelial cells of the villi were underwent degeneration and lamina propria was infiltrated by lymphocytes and plasma cells, and goblet cells were hyperplastic. There were rounded cutting plates in the funnel-shaped buccal capsule and transverse striation on sheath in hookworm, ultrastructurally, which were consistent with Uncinaria sp. The shape of eggs were ellipsoidal and morula, and some eggs contained a mobile larva. It was concluded that this badger was infected with Uncinaria.
Granulatous nodules on abdominal serosa of chick infected with Aspergillus species
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 407~411
Aspergillosis, caused by infection with Aspergillus fumigatus and less commonly by other Aspergillus species, is a prevalent and costly respiratory disease of poultry, In a flock of chicks, the number of birds, 4∼5 months old, had become gradually emaciated and subsequently died. Gross necropsy revealed multiple granulomatous masses on the abdominal serosa. The masses, 4∼15 mm in size, were attached on mainly intestinal wall. Also, the smaller masses in size were on mesentery and pancreas. However, only a few small white nodules were scattered throughout liver and lung in few samples. Microscopically, the mass were granulomatous with a central area of necrosis containing numerous septate, branched fungal hypae consistent with Aspergillus sp. These were surrounded by macrophages, giant cells, lymphocytes and fibrous tissues. Nodular lesions of liver and lung were seemed to spread hemotogenously from intestine and the possible route of infection was speculated by oral. This report is a Aspergillus-induced granuloma limited to the serosa of abdominal cavity, especially of intestinal wall.
Colibacillosis in domestic animals, a review
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 413~429
Escherichia coli is recovered from a wide variety of infections in many animals species. It may be a primary or secondary agent. Nursing and young animals are particularly susceptible, and urinary tract infections are frequent. The various serotypes of E coli are intestinal inhabitants of animals including humans and probably infect most mammals and birds : therefore, they have a cosmopolitan distribution. Colibacillosis refers to any totalized or systemic infection caused entirely or partly by E coli. Collibacillosis in mammals is most often a primary enteric disease, whereas collibacillosis in poultry is typically a secondary located or systemic disease occurring when host defenses have been impaired or overwhelmed. Other opportunistic bacteria, which can be identified by culture, may play a similar role to that of I coli in secondary infections. Collectively, infections caused by E coli are responsible for significant economic losses to the animal performance. From the standpoint of pathogenic mechanisms and diseases, four major categories of E coli are recognized : enterotoxigenic(ETEC), enteropathogenic (EPEC), enteroinvasive(EIEC), and enterohemorrhagic(EHEC). In addition, two less-well-defined E coli categories are recognized in animals and humans : enteroaggregative and cytotoxin necrotizing factor-positive. The aforementioned categories are represented by different serotypes. Certain serotypes show a host preference and are encountered more frequently in some disease syndromes. Of the four major categories, ETEC is the most common cause of diarrhea in calves, lambs, and pigs. Strains in the other categories cause the less-common diarrhea and other disease syndromes. Enterotoxins and pilus antigens are the two most prominent virulence factors thus far identified for ETEC. Two enterotoxins, one heat-stable(ST) and one heat-labile(LT), are produced by enterotoxigenic strains of E coli : not all culture produce both of these plasmid-based enterotoxins.
Experimental infection or Argulus juponicus in freshwater fishes
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 431~437
Argulus spp, a small group of parasitic curstaceans called Branchiura, is particularly important in freshwater acquaculture. We investigated the infection of Argulus to several different species of fishes and therapy effect of masoten. Argulus japonicus was collected from Okjeong lake, Chonbuk province and experlmen-tally infected to freshwater fishes from July to August 1998. The results were as follows ; 1. The shape of a Agulus is an oval and dorsoventrally flattened, with first maxillae and second maxillae, and four pairs of legs. 2. The size of the adult stage of A japonicus was 3.2-5.0
2.3-2.9mm in female and 1.5-3.1
1.6-2.9mm in male. 3. In the trial of experimental infection with A japonicus to non-scaled fishes, Parasilurus asotus and Ictalurus punctalus, were infected and some of them died after severe infection. However, A japonica was not infected at all. 4. Masoten treatment for A japonicus was effective at 0.2 ppm once a day for 3 days and parasites on the surface of fishes disappeared after five days.
Studies on the efficacy of anthelmintics to goats infected with internal parasites
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 439~449
From September 1997 to August 1998, Korean indigeous goats infected with internal parasites were examined for efficacy of anthelminthics by fecal egg counts. Efficacy of anthelmintic drugs against gastointestinal Haemonchus contortus in goats were effective with Ivermectin(94.9%), Piperazine(92.8%), Levamisole(88.3%), Albendazole(68.2%), respectively. Albendazole was effective against goats with Haemonchus contortus in 3 herds, but not effective in 1 herds. Efficacy of anthelmintic drugs against gastointestinal Paramphistomim sp in goats were effective with Ivermectin(95.3%), Piperazine(93.3%), Albendazole(92.9%), Levamisole(91.1%), respectively. Efficacy of anthelmintic drugs against Eimeria sp in goats were effective with Toltrazuril(92.6%), Diclazuril(90.4% ), Nicarbazin (87.5%), Amprolium(70.0%), respectively. Amprolium was effective against goats with Eimeria sp in 3 herds, but not effective in 1 herds.
Studies on the brucellosis in Kyongbuk area
Korean Journal of Veterinary Service, volume 21, issue 4, 1998, Pages 451~465
The present study was carried out to investigate the prevalence of brucellosis in Kyungbuk area for the 3 years from 1966 to 1998. Collective milk samples were routinely screened to detect positive farms by using the milk ring test(MRT), and serum agglutination test was performed to detect sero-positive individuals in the MRT positive farms. Attempt were made to isolate the causative organismas from slaughtered sero-positive reactors and some biochemical and polymerase chain reation characters of the isolates were also made to identify the organisms. Seroprevalence to brucellosis in peoples who are close contact with infected dairy herds was also investigated. Brucellosis of dairy cattle was rare before 1997, but has been broken more frequently since early 1998. By the MRT for dairy herds, positive rate was gradually increased every year : 0.6% in 1996, 1.5% in 1997, 3.9% in 1998. Among 262 MRT-positive herds, only 21 herds(8.0%) showed positive brucellosis in serological test. The isolation rates of Brucella sp from tested materials were 51.2% in supramammary glands, 39.5% in milks, and 50.0% in pulmonary Iymphnode, respectively. Isolated strain and biotype were Brucella(B) arbortus biotype 1 in 26 heads, and were B suis biotype 1 in 2 heads. Isolated strain and vaccine strain were very similar in their colony morphology and staining. In drug susceptibility, isolated stains(B abortus) and vaccine strain(B abortus RB-51) were sensitive to ampicillin, gentamycin, kanamycin, neomycin, penicillin, streptomycin, and to tetracycline, but resistant to erythromycin. In the PCR, field strains reacted to BA and IS711 primers, and vaccine strain reacted to BA, IS711, and RB5l primers. In the plate agglutination test of 96 sera of human contacted with animals, serum antibody titer detected 1 : 100 in one person, 1 : 200 in one, and below 1 : 25 in the others.
