During the spring of 2009, a new influenza A (H1N1) virus of swine origin emerged and spread worldwide causing a pandemic influenza. Here, 329 naso-pharyngeal swabs collected from patients with flu-like symptoms were analyzed by real-time PCR for the presence of H1N1 2009 pandemic virus. Twenty-five samples collected from immunocompetent and immunodepressed patients contained the H1N1 pandemic virus. Phylogenetic analysis of the hemagglutinin and neuraminidase genes showed no obvious differences in terms of similarity and/or homology between the sequences identified in immunocompetent individuals and those obtained from immunocompromised patients...

Haemorrhagic septicaemia (HS) is an acute disease of cattle and buffaloes caused by Pasteurella multocida 6:B. Outbreaks of the disease have been closely associated with carrier animals that transmit the organism to susceptible animals during stressful condition. This study was conducted to determine whether goats exposed intranasally to P. multocida 6:B can transmit the organism to contact goats. Thirty-six healthy local Katjang goats were divided into four groups and goats of groups 1 and 3 were each inoculated intranasally with a 1-ml inoculum that contained 1 x 10(9) CFU/ml of live P...

We examined the relationships among the activity of daily living (ADL), oral cavity care, and the number of oral cavity microorganisms in 40 patients with cerebrovascular diseases (CVD). The CVD patients were classified into 4 groups, I, II, III and IV based on their ADL and the method used for oral cavity care. The ADL was highest in group I and lowest in group III. Only the patients of only group III could not eat by themselves and were receiving naso-esophageal feeding. Oral cavity care was performed by the patients themselves in groups I and IV, but was performed by caregivers in groups II and III...

In order to investigate the specificity of low titer antibodies to BHV 1, twelve cattle were subjected to stress and dexamethasone treatment. They were monitored virologically by inoculating cell cultures with naso-pharyngeal-, ocular- and vaginal- or preputial swabs and serologically by assessing the prevalence and incidence of antibodies to bovine, caprine-, porcine-, and equine herpesviruses and to bovine leukemia virus. Antibodies were classified as specific for BHV 1 if the animals excreted IBR virus, or if the antibodies neutralized BHV 1 and reacted with BHV 1 antigens, or if they reacted additionally with CapHV antigens...

Coagulase-negative staphylococci have gained increasing importance in burns, whereas interest is no longer focussed on Pseudomonas bacteria. By means of microbiological analysis of swabs taken from patients, environment and staff, we trailed the routes of infection in an intensive-care unit for burns. Analysis of patients: In 27 out of 11 patients the same biotype of Staphylococcus epidermidis could be identified; 22 of these occurred in swabs from wounds. The phagotypification of Staphylococcus aureus showed the same phagotype in 28 out of 41 swabs taken from infected wounds of 10 patients...
