Background: The aim of the present study was to evaluate whether findings on initial chest computed tomography (CT) of influenza pneumonia can help predict clinical outcome. Methods: We reviewed all adult patients admitted to the Emergency Department (ED) with a confirmed diagnosis of novel influenza A H1N1 virus (2009 H1N1) pneumonia, who underwent chest CT upon admission between Aug 26, 2009 and Jan 31, 2010. Radiologic findings were characterized by type and pattern of opacities and zonal distribution. Clinical outcome measures were intensive care unit (ICU) admission, mechanical ventilation, and inhospital death. Results: Of 59 patients diagnosed with 2009 H1N1 pneumonia, 41 (69.5%) underwent chest CT on admission into ED. Nine (22%) of these patients developed adverse clinical outcomes requiring the following treatments: 9 (22.0%) ICU admissions, 5 (12.2%) mechanical ventilation, and 3 (7.3%) inhospital deaths. Counting the number of patients with more than 4 involved lobes, the sensitivity, specificity, positive predictive value, and negative predictive value for detection of adverse clinical outcome were 67%, 84%, 55% and 80%, respectively. Conclusion: Extensive involvement of both lungs (over 4 lobes) is related to ICU admission, mechanical ventilation, and inhospital death. Initial chest CT may help predict an adverse clinical outcome of patients with 2009 H1N1 influenza pneumonia.

Caprine arthritis encephalitis (CAE) virus is a causative agent of caprine arthritis-encephalitis. In our previous study we reported a prevalence of CAE. In this study, we described the further detailed pathological features of CAE and examined the detection of virus by in situ hybridization (ISH). Histopathologically, interstitial pneumonia and bronchopneumonia in lung, focal inflammation in mammary glands, perivascular cuffing in brain, arthritis, and focal necrosis, mild steatosis, inflammatory cell infiltration of liver were noted. CAEV proviral-DNA was identified by nested polymerase chain reaction (PCR) in blood cells, brain, synovial fluid, and lymph node. Confirmation by nested PCR involved amplification of a 296 bp ($1^{st}$ PCR) and 185 bp ($2^{nd}$ PCR) fragments corresponding to a conserved region on the gag gene of CAEV. Positive ISH signals were detected in the brain and liver. In conclusion, significant histopathological findings included parenchymal infection in various organs, including the lung, liver, brain, joint, and mammary gland were noted in the CAEV infected dairy goat. ISH can help confirm the diagnosis of CAE in formalin-fixed samples.

We report that mycoplasma organisms from lung tissues of slaughter pigs were identified to genes fragments with references use of nested-PCR technique(nPCR). Seven strains of mycoplasma species were isolated from 70 lung tissues. The organisms were detected by in vitro amplification of 16S rRNA and 23S rRNA genes. Nucleotide sequences of the spacer between 16S and 23S in the ribosomal RNA operons of mycoplasma were identified by the analysis of products from the nested PCR. Four common PCR primers, MhF1, MhF2 MhR1 and MhR2, were designed by analysis between these sequences by first amplified with F1, R1 and second with F2, R2, respectively. Specific amplification of the spacer region for reference strains of M. hyopneumoniae, M. hyorhinis, M. flocculare were confirmed by first round of PCR in which the traduced fragments of 690bp, 460bp, 630bp. But amplications of second round was changed to 240bp, 210bp, 230bp, respectively. Three different strains (M. hyopneumoniae:4, M. hyorhinis:2, M. flocculare:1) were detected by the nested-PCR technique. The results suggest that the detection of swine mycoplasma by n-PCR can be analyzed the nucleotide sequences between rRNA operons and homology study.

Mycoplasmal pneumonia of swine(MPS) cause by Mycoplasma hyopneumoniae has been recognized as a serious impediment to swine production due to chronic respiratory disorder which result in the weight loss and decreased feed conversion. The disease causes a great economic losses in pig industry by characterizing with high morbidity, low mortality, growth retardation and low feed efficiency. The present study was conducted to investigate the titers of antibody against M hyopneumoniae from the regional and seasonal groups of the slaughtered pigs by enzyme-linked immunosorbent assay(ELISA). The result have shown that the average seropositive rate of M hyopneumoniae infection was 84.6% . The regional seropositive rate in Korea showed 87.4% in Kyonggj, 83.4n in Kangwon, 89.2% in Chungnam and 77.6% in Chungbuk area, respectively. Also the seasonal seropositive rate was appeared as 78.6% in spring,90.1% in summer, 76.9% in autumn and 83.8% in winter, respectively.

Pneumocystis carinli is an established cause of pulmonary infections in immuno-compromised hosts. Several cytoiogical stains, such as Papanicolaou, Gomori methenamine sliver(GMS) and Diff-Quik have been used for detection of the organism, but occasionally can be laborious and, due to a degree of nonspecificity, may be misleading. We evaluated the diagnostic utility of immunocytochenmical stains that recognize P. carinii in bornchoalveolar lavage from experimentally Induced P. carinii pneumonia rats(n=15). In audition to routine stains for diagnosis by morphologic recognition of P. carinii on Papanicolaou, GMS and Diff-Quik stains, bronchoalveolar lavage samples were reacted with immunocytochemical stains using monoclonal antibodies(MAB) 092 and 902. In bronchoalveolar lavage P. carinii organisms were detected In 9 of 10 cases(90%) using each MAB 092 and 902, whereas GMS and Diff-Quik stains demonstrated P. carinii in 13(86%) and 11(73%) of 15 cases respectively. In lung tissue specimens(n=15) P. carinii organisms were well identified on GMS stain and immunohistochemical stains using MAB 092 and 902 in ail cases. We believe that the immunocytochemical staining using MAB 092 and/or 902 is a very useful and diagnostic tool In addition to GMS and Diff-Qulk stain to detect P. carinii organisms in bronchoalveolar lavage.

Penicillin antibiotics such as penicillin G, ampicillin and amoxicillin have been widely used in the pig industry to control salmonellosis, bacterial pneumonia, and urinary tract infections. Extensive use of antibiotics in veterinary clinics has resulted in tissue residues and bacterial resistance. To prevent unwanted drug residues entering the human food chain, extensive control measures have been established by both government authorities and industries. The demands for reliable, simple, sensitive, rapid and low-cost methods for residue analysis of foods are increasing. In this study, we established a rapid prediction test for the detection of pigs with unacceptable tissue residues of penicillins. The recommended therapeutic doses of three penicillins, penillin G (withdrawal time, 7 days), ampicillin (withdrawal time, 7 days) and amoxicillin (withdrawal time, 14 days), were administered to three groups of 20 pigs each. Blood was sampled before drug administration and during the withdrawal period. The concentration of penicillins in plasma, determined by a semi-quantitative ELISA, were compared to that of internal standard, 4 ppb, which corresponded to the Maximum Residue Limit in milk. The absorbance ratio of internal standard to sample (B/Bs) was employed as an index to determine whether drug residues in pig tissues were negative or positive. That is, a B/Bs ratio less than 1 was considered residue positive, and larger than 1 negative. All 60 plasma samples from pigs were negative to three penicillins at pretreatment. Penicillin G could be detected in the plasma of the treated pigs until day 4 post-treatment and ampicillin until day 2, whereas amoxicillin could be detected until day 10 of its withdrawal period. The present study showed that the semi-quantitative ELISA could be easily adapted to detect residues of penicillin antibiotics (penicillin G, ampicillin and amoxicillin) in live pigs.
