The present study was undertaken to determine the present status of fowl cholera (FC) infection of poultry in Gazipur district during September 2016 to February 2017. A total of 282 either dead or sick birds (Layer and Sonali) were taken as sample in which the sick birds were subjected to record clinical data and consequently the dead birds were for post mortem examination. Hence, overall 12.41% prevalence was found for FC and about 87.59% was for mixed other diseases.  All the birds were grouped into six named as A1, A2 and up to A6 accordingly their age. The highest incidence (29.79 %) was found in A1 (8-20weeks) group and the lowest was 4.26% in A5 (51-60 weeks) group. Furthermore, six FC infected farms were categorized to treat with six specific antibiotics individually. Thereafter, the highest recovery rate (89.6% and 87.5%) was recorded in two farms using Enrofloxacin and Gentamicin particularly. The lowest recovery rate (60%) was in Erythromycin treatment group. However, the layer birds of six farms lost their body weight almost 11.84%, specifically the highest percentages (16.49%) was in treated with Ampicillin and lowest percentages (5.79%) found in a farm treated with Gentamicin. In brief, FC commonly appears just near to laying age and therapeutic management trivially decreases the body weight that ultimately shoots up the production cost.

SummaryChildhood excess weight is probably associated with, or reflected in, parental attitudes. The objective of this study was to study the relationships between childhood excess weight and parental attitudes. The study subjects were 53 boys and 56 girls, aged 6–10, regularly attending schools in Porto Alegre, south Brazil, and one of their parents or caregivers. Attitudes of the parents or caregivers were assessed by the Child Feeding Questionnaire (CFD). Weight and height of the children were measured, parents self-reported their weight and height and body mass indexes were calculated for both. The WHO criteria for overweight and obesity were used for the adults. The CDC criteria for overweight and risk for overweight were used for the corresponding children. Boys presented excess weight more often than girls. The parents of children with excess weight showed higher scores for perceived child weight, concern about child weight, restriction and monitoring. In logistic regression, excess weight in children was associated with perceived child weight, restriction and male sex; pressure to eat was negatively associated with excess BMI. In Porto Alegre, south Brazil, excess body weight in children aged 6–10 is associated with parental perceived child weight and concern about it, monitoring and restriction; being a boy increases the odds of being overweight.

Pasteurella multocida can invade and translocate through endothelial cells and result in vascular-system infection, which can cause severe economic losses in the poultry industry. Antibacterial therapy (especially florfenicol) plays an important part in controlling P. multocida infection. To preserve the effect of florfenicol, in vivo pharmacokinetic/pharmacodynamic (PK/PD) modeling of florfenicol against three P. multocida strains in duck was established. Then, the efficacy of the currently marketed dose, a rational dosage regimen for populations, and the PK/PD cutoff were predicted through Monte Carlo simulations (MCSs). The area under the concentration–time curve from 0 to 24 h/minimum inhibitory concentration (AUC0–24 h/MIC) was the optimal PK/PD parameter. The PK/PD surrogate values of florfenicol against P. multocida were similar using different organs as the PD target, but varied in different strains. For the florfenicol-sensitive strain 0825Y1, when the AUC0–24 h/MIC reached 117.54 and 108.19, florfenicol showed a bactericidal effect in the liver and lung, respectively. For the florfenicol-sensitive strain 0901J1, the corresponding value was 78.39 and 54.30, respectively. For the florfenicol-resistant strain JY160110, florfenicol could attain a maximum effect of 1 – log10 reduction in bacteria in the liver and lung when the AUC0–24 h/MIC reached 2.03 and 2.06, respectively. The PK/PD-based prediction for the population dose indicated a poor effect for the low end of the currently marketed dose (40 mg/kg body weight per day), but a robust effect for the high end of the currently marketed dose (60 mg/kg body weight per day) with a target attainment rate of 92.79% and 81.44% against P. multocida in mainland China and worldwide, respectively. The recommended dose optimized by MCSs was 52 mg/kg body weight in mainland China. The PK/PD cutoff of florfenicol against P. multocida at the low end and high end of the current daily dose (40 and 60 mg/kg body weight) and predicted daily dose in mainland China (52 mg/kg body weight) was 0.25, 4, and 0.5 μg/ml, respectively. These results suggested that more than one strain should be involved for PK/PD modeling and contributed to rational use of florfenicol in populations. We also provided fundamental data for determination of florfenicol breakpoints in poultry.

1. Three groups of cockerels were reared from 3 to 11 weeks of age on increasingly severe quantitative food restriction treatments, resulting in body-weight values of 12, 19 and 27% below that of a control group which was fed ab lib.2. The rate of uptake of L-arginine, glycine, L-lysine and L-phenylalanine was measured in vitro using intestinal rings, over a 5 min incubation period.3. Uptake of L-arginine was significantly increased with increasing degrees of body-weight restriction. This amino acid and L-lysine were the only two to show a significantly enhanced uptake rate as a result of the restriction treatments.4. No significant differences were noted in the case of glycine or L-phenylalanine uptake following food restriction, indicating a certain selectivity in the alteration of absorption rates following food restriction, when such tests are conducted in vitro.

Vacuolated cells in the liver of young rats were studied by light and electron microscopy following the administration of vitamin A (200 units per gram of body weight). Their characteristics were compared with similar cells found in untreated animals.In rats given vitamin A, cells with vacuolated cytoplasm were a prominent feature. These cells were found mostly in a perisinusoidal location, although some appeared to be in between liver cells (Fig. 1). Electron microscopy confirmed their location in Disse's space adjacent to the sinusoid and in recesses between liver cells. Some appeared to be bordering the lumen of the sinusoid, but careful observation usually revealed a tenuous endothelial process separating the vacuolated cell from the vascular space. In appropriate sections, fenestrations in the thin endothelial processes were noted (Fig. 2, arrow).
