A monitoring study was carried out with the aim to assess the level of toxic metals i.e., lead (Pb), cadmium (Cd), arsenic (As) and mercury (Hg) in different vegetables grown in Sindh province of Pakistan during 2007-2008. Two hundred ten samples of twenty one vegetables were collected from farmers’ field of Sindh and exporters at Karachi. These samples(More)
Newcastle disease (ND) is a contagious viral disease of many avian species particularly domestic poultry, and is responsible for devastating outbreaks in the poultry industries around the globe. In spite of its importance and endemicity in Southern Asia, data on the genetic nature of the viruses and epizootiological information of the disease is scarce. In(More)
Genetic hybridisation between parasitic nematode species has potentially important consequences. It could lead to the introgression of genes between species including those involved in pathogenicity, host specificity, transmission and drug resistance. It could also complicate diagnosis and control. However, there are few compelling examples of its(More)
Newcastle disease (ND) is one of the most deadly diseases of poultry around the globe. The disease is endemic in Pakistan and recurrent outbreaks are being reported regularly in wild captive, rural and commercial poultry flocks. Though, efforts have been made to characterize the causative agent in some of parts of the country, the genetic nature of strains(More)
We report the complete genome sequence of avian paramyxovirus 1 (APMV-1) isolated from an acute and highly contagious outbreak in pheasants (Pucrasia macrolopha) in Lahore, Pakistan. Biological and serological characterization showed a velogenic strain of APMV-1, which was further confirmed by the sequence analysis of the cleavage site in the fusion(More)
Apart from natural reassortment, co-circulation of different avian influenza virus strains in poultry populations can lead to generation of novel variants and reassortant viruses. In this report, we studied the genetics and functions of a reassorted non-structural gene (NS) of H9N2 influenza virus collected from back yard poultry (BYP) flock. Phylogenetic(More)
Agitation is a neurologic complication that may occur after electroconvulsive therapy (ECT). Severe agitation after ECT has been associated with multiple factors, both anesthetic and psychiatric. This case report describes severe postictal agitation after ECT in a patient with bipolar affective disorder. The clinical management of this challenging(More)
Newcastle disease virus (NDV) causes severe and economically important disease in poultry around the globe. None of NDV strains in Pakistan have been completely characterized and the role of rural poultry in harbouring NDV is unclear. Since they have a very important role for long-term circulation of the virus, samples were collected from apparently healthy(More)
Paratuberculosis is a chronic bowel disease of ruminants caused by Mycobacterium avium subsp. paratuberculosis (MAP). Its secretion through semen highlights the importance of paratuberculosis-free breeding bulls. The breeding and teaser bulls at three semen production units (SPUs) located in Punjab, Pakistan, were screened for the presence of antibodies(More)
Newcastle disease virus (NDV) infects wild and domestic birds but causes contagious and lethal disease in domestic poultry. ND is currently endemic in Pakistan, but no complete genome sequence of a Pakistani NDV isolate has been reported. An NDV strain isolated from a commercial poultry farm was completely sequenced. Phylogenetic analysis revealed that the(More)
