Background Sepsis is a major contributor to neonatal mortality, particularly in low-income and middle-income countries (LMICs). WHO advocates ampicillin-gentamicin as first-line therapy for the management of neonatal sepsis. In the BARNARDS observational cohort study of neonatal sepsis and antimicrobial resistance in LMICs, common sepsis pathogens were characterised via whole genome sequencing (WGS) and antimicrobial resistance profiles. In this substudy of BARNARDS, we aimed to assess the use and efficacy of empirical antibiotic therapies commonly used in LMICs for neonatal sepsis.Methods In BARNARDS, consenting mother-neonates aged 0-60 days dyads were enrolled on delivery or neonatal presentation with suspected sepsis at 12 BARNARDS clinical sites in

The mating attributes in relating to parasitism and progeny production capacity of the parasitoid Habrobracon hebetor Say, using Plodia interpunctella (Hübner) as a host, were investigated in laboratory studies. The results indicated that 100% of the host larvae were parasitized by different individuals of H. hebetor females that were mated by the same male. Mating duration did not differ significantly among different successive matings with different females and had no effect on the rate of parasitism. In general, pairs that had their copulation early after emergence exhibited the maximum rate of parasitism as compared to delayed intervals. Moreover, the age of the H. hebetor females had no effect on the percentage of parasitism. The maximum parasitism percentage was recorded for the H. hebetor individuals that had been developed from the age group of the 6-d-old adults. The male: female ratios did not differ significantly among the female age groups. The percentage of parasitism clearly indicated a decrease with the increase of the male: female ratio. Overall, the results of the present work can be further utilized in mass rearing and release of H. hebetor in biological control programs in stored product protection.

Thyroid uptake and scintigraphy using Tc-99m pertechnetate has proven to be more advantageous than with I-131 iodide, since the images have better quality, the procedure is faster and the patient is submitted to a lower radiation dose. Tc-99m has been used worldwide to study the thyroid function because of a number of advantages such as short half-life, short biological half-life, short effective half-life, short retention in gland and no Beta (β-) radiation, providing low dose to gland (10,000 times less than that of I-131), low cost and readily availability. Otherwise, I-131 with its high radiation burden (1-3 rad/mCi) has long half-life and causes Beta (β-) particle emission. Its main gamma photon has high energy (364 keV) which also causes poor image quality.

The present study was undertaken to find out the prevalence of gastrointestinal nematodes in pigeon (columba livia) at Rajshahi division from 01-01-2016 to 15-12-2016 and to evaluate the comparative efficacy piparazine citrate and levamisole HCL. Total 3 different species of parasites were recorded in this study and those were Ascaridia columbae, Capillilaria obsignata, Raillietina tetragona. Out of 263 pigeon, 109 pigeon having ascarid and capillaria positive were treatment with piparazine citrate and levamisole HCL. The pigeon were treated with recommended (10g mixed in 6 litre drinking water for 100 pigeon) dose of Ascarex® and recommended (1gm mixed in 1 litre drinking water) dose of Avinex® orally, respectively. The recovery rate of ascariasis at 7th days was 50.9% and capillariasis was 51.85%. After 21th days the recovery rate of ascariasis was 72.72% and capillariasis was 66.66%. The efficacy of drugs is more in case of young (77.27% at 7th days and 87.36% at 21th days) than adult (44.82% at 7th days and 65.51% at 21th days).In exotic breeds efficacy is good (60.41% at 7th days and 85.41% at 21th days) than indigenous breeds (44.26% at 7th days and 66.65% at 21th days). The recovery rate is more in traditional (65.3% at 7th days and 78.33% at 21th days) than commercial farming system (42.85% at 7th days and 58.33% at 21th days). Res. Agric., Livest.

Fecundity and egg viability of Tribolium castaneum (Herbst) females were significantly (P<0.01) reduced by synthetic pyrethroids and an alkaloid containing insecticide nimbicidine. In control, the average number of eggs laid by each female/day was 12.18. The lowest number of eggs laid by each female/day was noted as 4.38 when combining nimbicidine with two pyrethroids i.e., cypermethrin and deltamethrin. The percentage of egg hatching without insecticide treatment was 95%. The lowest percent of egg hatching was 63.95 when the adult female was fed on flour medium treated with combined doses of cypermethrin, deltamethrin and nimbicidine. Among the treated insecticides, nimbicidine (80.69%) proved effective in reducing the fertility than those of cypermethrin (86.05%) and deltamethrin (88.52%).
