ICPI and IVPI determination: The ICPI of Desi and layer (commercial name Babcock-300) was analyzed and results are depicted in the table 1.
Intravenous pathogenicity index (IVPI): Desi and layers (commercial name Babcock-300) were raised for four weeks and found sero-negative for H9N2 by HI test were used for determination of IVPI.
Descriptive statistics were employed to estimate the mean and interproximal gingival indices (GI; IGI), gingival bleeding index (GBI), overall gingival inflammation prevalence, and severity; the overall average for mean and interproximal visible dental plaque indices (VPI; IVPI) and calculus index were calculated, with 95% confidence intervals.
The high VPIs and IVPIs in virtually all the participants of the study suggest that inadequate or insufficient oral hygiene is practiced in all 3 cities.
According to the clinical signs and number of dead birds during 10 days postinfection (PI), intravenous pathogenicity index (IVPI
) of H9 virus was calculated in birds of group B (H9 virus infected) and compared with the birds of group A (Control) as per standard procedure (WHO, 2002).
Even as the code went into effect there was scant evidence of progress on implementing and funding the IVPI
. Critics of the initial proposal thought the expense of the IVPI
would raise mortgage loan origination costs, and this concern remains.
While the IVPI
has not yet been established, an interim Web site is being created to receive and register complaints from appraisers and other entities on non-compliance with the HVCC.
of 0.00 indicated the virus was not of high pathogenicity for chickens.
Groups of 10 chickens were inoculated with the 7 influenza (H5N1) viruses to determine the IVPI
As the occurrence of multiple basic amino acids in the cleavage site marks highly pathogenic H5 and H7 influenza A strains (9), this finding confirms the results of the IVPI
Virus isolated from birds on the same source farm as the human isolate A/Canada/444/04 was confirmed as HPAI H7N3 by genotyping and IVPI
. Virus from birds on the same source farm as A/Canada/504/04 showed insertion sequence match with HPAI H7N3, but IVPI
was not performed (C.
Virulence was assessed by the standard intravenous pathogenicity (IVPI
) test by using 6-week-old SPF chickens and the standard pathotyping test by using 4-to 6-week-old SPF chickens (19,20).
