Molecular characterization of Indian isolates of infectious bursal disease virus from broiler chickens.

The present study was undertaken to characterize recent field isolates of infectious bursal disease virus (IBDV) by reverse transcription-polymerase chain reaction (RT-PCR) and partial sequencing of VP2 gene. The virus could be detected in 17 of 20 field samples from broiler chickens in Haryana state, India as well as in all the four vaccine strains. Nucleotide sequences of four field isolates and one vaccine strain were compared with 10 reported IBDV strains from different parts of the world.

Effects of feeding Fusarium verticillioides (formerly Fusarium moniliforme) culture material containing known levels of fumonisin B1 in Japanese quail (Coturnix coturnix japonica).

One hundred fifty 1-d-old quail chicks (Coturnix coturnix japonica) were divided into 2 groups. The 2 groups were designated as controls (CX) and fumonisin-fed birds (FX) with each containing 50 and 100 chicks, respectively. The birds in group CX were maintained on quail mash alone, whereas the birds in group FX were maintained on diets supplemented with 300 ppm of fumonisin B1 from Fusarium verticillioides (formerly Fusarium moniliforme) culture material from 1 d.

HIV-1 infection in early seroconversion stage missed by rapid or ELISA tests--two case reports.

Two cases of HIV-1 infection demonstrating lack of sensitivity of rapid and ELISA screening tests are being reported. The first case was that of a 23 years old female whose recent infection was picked up by ELISA (Tetra ELISA) test but missed by two rapid tests (Comb AIDS and HIV Tridot). The 2nd case presumably too in early seroconversion phase, was that of a 39 years old male.

Seroprevalence of hepatitis C virus (HCV) in health care workers of a tertiary care centre in New Delhi.

Hepatitis C virus (HCV) is a parenterally transmitted virus that poses an occupational hazard to the health care workers (HCWs). No significant data are available regarding the prevalence of HCV in health care workers in India. The present study was designed to determine the seroprevalence of HCV infection in health care workers in a tertiary care centre in New Delhi.

Individual and combined effects of Fusarium moniliforme culture material, containing known levels of fumonisin B1, and Salmonella gallinarum infection on liver of Japanese quail.

Three hundred day-old Japanese quail (Coturnix coturnix japonica) were divided into two groups with 150 quail in each group. One group was maintained on quail mash alone, while Fusarium moniliforme culture material was added to quail mash in the second group from day 5 of age and was supplied at a rate of 150 ppm fumonisin B1 (FB1)/kg mash. At day 21, each group was further subdivided into two groups, yielding four groups with 75 birds apiece, which served as the control (group CX), the Salmonella Gallinarum alone group (group CS), the FB1 alone group (group FX), and the group fed FB1 and infected with Salmonella Gallinarum (group FS).

Effect of ochratoxin A on broiler chicks challenged with Salmonella gallinarum.

1. A study was conducted to evaluate the effects of ochratoxin A (OA) on broiler chicks challenged with Salmonella gallinarum. 2.

Effects of Fusarium moniliforme culture material containing known levels of fumonisin B1 on progress of Salmonella Gallinarum infection in Japanese quail: clinical signs and hematologic studies.

To study the individual and combined effects of fumonisin B1 (FB1) toxicity and Salmonella serotype Gallinarum infection, Japanese quail (Coturnix coturnix japonica) were fed Fusarium moniliforme culture material (2.5%), 150 mg FB1/kg ration, and were subsequently challenged orally with Salmonella Gallinarum organisms (2 x 10(4) colony-forming units) at 21 days of age. The chicks were fed culture material containing FB1 from day 5 till the end of the experiment.

A pilot seroepidemiological study of cytomegalovirus infection in women of child bearing age.

Three hundred and forty serum samples collected from women of child bearing age, without any clinical evidence of cytomegalovirus (CMV) infection, were screened for the presence of IgG antibodies against CMV by ELISA test. The IgG antibodies were detected in 297 which gave prevalence rate of 87.4%.

Pathological changes in broiler chickens fed ochratoxin A and inoculated with Escherichia coli.

A study was conducted to evaluate the effects of ochratoxin A (OA) on Escherichia coli-challenged broiler chickens. One hundred and eighty-four one-day-old broiler chicks were divided into two groups of 92 chicks each, with one group fed a control mash diet and the other fed a mash diet containing 2 parts/10(6) OA. On day 14, each group was further subdivided into two groups with one group inoculated with E.

Primary rubella virus infection: prevalence and relationship to pregnancy wastage.

A total of 580 females (200 in prepubertal age and 380 in reproductive age group) were screened for primary rubella infection. Rubella specific serology (IgM and IgG) was studied by ELISA using commercially available diagnostic kits. IgM seropositivity was observed in 56 of 200 females (28%) of prepubertal age and 26 of 380 females (6.

Mycobacterial cervical lymphadenitis in childhood.

A study of 190 children of chronic cervical lymphadenitis showed tuberculous etiology on histopathological examination in 92 (48.4%) and bacteriological evidence of mycobacterial infection (smear and/or culture) in 42 (22.1%).

Effect of ochratoxin A on Escherichia coli-challenged broiler chicks.

A study was conducted to evaluate the effects of ochratoxin A (OA) on Escherichia coli-challenged broiler chickens. Day-old broiler chicks were separated into two groups of 92 chicks each, with one group fed a control mash diet, and the other fed a mash diet containing 2 ppm OA. On day 14, each group was further separated into two groups, with one group inoculated with E.

Treatment of focal glomerulosclerosis with pulse steroids and oral cyclophosphamide.

Patients with steroid-resistant nephrotic syndrome often have an unsatisfactory long-term outcome and are at risk of developing chronic renal failure. We prospectively treated 65 children with idiopathic steroid-resistant nephrotic syndrome and focal segmental glomerulosclerosis (FSGS) with intravenous pulses of corticosteroids and oral cyclophosphamide. Dexamethasone (5 mg/kg) or methylprednisolone (30 mg/kg) was administered intravenously, initially 6 pulses on alternate days, followed by 4 fortnightly and 8 monthly pulses.

Occurrence of fumonisin B1 in maize and poultry feeds in Haryana, India.

A total of 100 maize and 50 poultry feed samples collected in 1998 at random from nine and eight districts of Haryana, respectively, were analysed for fumonisin B1. The samples were collected from poultry farms, feed manufacturers and markets. Ninety one (91%) maize samples and forty two (84%) poultry feed samples were found to contain fumonisin B1.

Pharmacologic issues in the management of septic shock.

Despite our increased understanding of the biochemistry and physiology of sepsis, the treatment of septic shock remains a challenge. Initial management of septic shock entails urgent and emergent stabilization of the patient followed by broad-spectrum, empiric antibiotic therapy. After volume resuscitation, vasopressors or inotropic therapy or both may be necessary to restore perfusion.
