Abstract
Bovine herpesvirus 1
(BoHV-1) is an evident respiratory and reproductive pathogen in bovines. It
causes infectious bovine rhinotracitis (IBR) and reproductive disorders. Present
study evaluated the prevalence of BoHV-1 among the healthy and sick cattle and
buffaloes. Two hundred blood samples were randomly collected from the animals of
district Okara, Pakistan. To detect BoHV-1 antibodies, indirect ELISA was
performed. Out of 200 samples from both species (cattle and buffalo), an overall
prevalence of BoHV-1 of 124/200 (62%) was obtained. Samples from buffalo had
higher species-specific prevalence 64/98 (65%) than samples from cattle 60/102
(58.8%). Overall, BoHV-1 was more prevalent in female (73.35%) animals as
compared to male animals (48.5%). Present study depicted that 84/124 (67.70%)
animals from positive results were apparently healthy and 40/124 (32.25%)
animals from seropositive results were sick. Identification and molecular
characterization was performed on sixty seropositive blood samples, PCR was
performed by using glycoprotein E gene primers on isolated DNA from these
samples, six were positive 6/60 (10%), and gene sequencing and phylogenetic
analysis had shown close similarities with other BoHV-1 gE gene sequences world
widely. The accession number assigned to these samples in GenBank were
OQ656376.1 and OQ656377.1. Subtyping of BoHV-1 was conducted by multiplex PCR
following HindIII enzyme activity, three samples were identified as BoHV-1.1
that indicated BoHV1.1 prevalence in study area. In this study, Multiplex PCR
proven as efficient, economical and rapid technique for diagnosis and subtyping. This study will be
helpful in vaccine development and in devising measures to control the spread of
BoHV-1.
