This study was carried out at the Razi Institute during 2005-2006 with inspecting 12168 lung tissue of slaughtered sheep and goats at the Ziaran Abattoir. Pneumonia were diagnosed in 282 cases and the affected lung tissue was collected and transferred to the Bacteriology and Pathology Departments for isolating of Pasteurella spp. and interpretation of histopathologic lesions. Pasteurella mult...

Humoral immune response in cattle and buffaloes vaccinated against Pasteurella multocida B: 2 with reference to levels of B Lymphocytes IL-2R+Harsh Shaveta, Deepti Chachra, H M Saxena, Mudit Chandra

We studied the comparative in vitro activities of ABT-773, a new ketolide, against 268 aerobic and 148 anaerobic recent isolates from clinical bites using an agar dilution method and inocula of 10(4) CFU/spot for aerobes and 10(5) CFU for anaerobes. The following are the MIC ranges and MICs at which 90% of isolates are inhibited (MIC(90)s) of ABT-773 for various isolates, respectively: Pasteure...

More than 5 million Americans are bitten by animals, usually dogs, annually. Bite patients comprise ∼1% of all patients who visit emergency departments (300,000/year), and approximately 10,000 require hospitalization and intravenous antibiotics. Ceftaroline is the bioactive component of the prodrug ceftaroline fosamil, which is FDA approved for the treatment of acute bacterial skin and skin str...

Experiments using different types of antigen-adjuvant preparations were conducted in outbred sheep to compare effects of adjuvants on immune responses. Trinitrophenyl-ovalbumin (TNP-ovalbumin) incorporated in a preparation with nonionic block copolymers elicited high antibody titers to both ovalbumin and TNP. Different humoral immune responses were observed when Pasteurella haemolytica lipopoly...

The full sequence of plasmid p250, isolated from Haemophilus paragallinarum strain HP250, has been obtained. The plasmid contains seven ORFs: a putative integrase, a putative replication protein (repB) and five ORFs similar to those from the haemocin (bacteriocin) hmcDCBAI operon from Haemophilus influenzae. Of 19 other non-plasmid-containing H. paragallinarum strains screened (11 serovar refer...

We studied the comparative in vitro activity of ertapenem, a new carbapenem, against 240 aerobic and 180 anaerobic recent clinical bite isolates using an agar dilution method and an inoculum of 10(4) cfu/spot for aerobes and 10(5) cfu/spot for anaerobes. Ertapenem inhibited 410/420 (98%) of the isolates tested at < or = 4 mg/L with only 4/5 Campylobacter gracilis and 1/3 Campylobacter rectus st...

Synergism was demonstrated between Sendai virus and Pasteurella pneumotropica in the respiratory tract of mice showing no evidence of previous infection with either agent. Mice aerosol challenged with P. pneumotropica invariably eliminated the viable organism from their lungs within 72 h. In contrast, intrapulmonary killing was delayed in animals previously infected with Sendai virus. Maximum s...

A selective enrichment procedure, using two new selective media, was developed to isolate Pasteurella multocida from wild birds and environmental samples. These media were developed by testing 15 selective agents with six isolates of P. multocida from wild avian origin and seven other bacteria representing genera frequently found in environmental and avian samples. The resulting media--Pasteure...

Soft-tissue infection by Pasteurella multocida in humans is usually associated with a dog- or cat-related injury, and these infections can become aggressive. We sequenced the type strain P. multocida subsp. multocida ATCC 43137 into a single closed chromosome consisting of 2,271,840 bp (40.4% G+C content), which is currently available in the NCBI GenBank under the accession number CP008918.
