Abstract The experiment was conducted to investigate the effects of antibiotics on blood profiles and serum inflammatory mediators of weaned pigs experimentally infected with F18 Escherichia coli (E. coli). Twenty-six pigs (6.88 ± 1.03 kg BW) were individually housed in disease containment rooms and randomly allotted to one of three treatments with 8–12 replicate pigs per treatment. The three dietary treatments were control diet and 2 additional diets supplemented with 0.5 or 50 mg/kg carbadox, respectively. The experiment lasted 18 d (7 d before and 11 d after first inoculation [d 0]). F18 E. coli inoculum was daily and orally as 1010 cfu/3 mL for 3 d. Blood samples were collected before E. coli inoculation and on d 2, 5, 8, and 11 post-inoculation (PI). Total and differential blood cell count were analyzed by CBC test. All data were analyzed by ANOVA using PROC MIXED of SAS. Supplementation of low-dose antibiotics had greatest (P < 0.05) neutrophils but lowest (P < 0.05) monocytes on d 2 PI, compared with control and high-dose antibiotics groups. Pigs in the low-dose antibiotics group still had higher (P < 0.05) white blood cell counts and lymphocytes than pigs in the other groups on d 11 PI. In consistent with CBC results, pigs supplemented with low-dose antibiotics had greatest (P < 0.05) serum C-reactive protein on d 2 and 5 PI and serum TNF-α on d 5 PI, compared with pigs in the control and high-dose antibiotics groups. No differences were observed in the red blood cell profiles between pigs in control and low-dose antibiotics groups, whereas supplementation of high-dose antibiotics had lowest (P < 0.05) packed cell volume but highest (P < 0.05) mean corpuscular hemoglobin concentration among three treatments. In conclusion, low-dose antibiotic supplementation may exacerbate systemic inflammation caused by F18 E. coli infection.

Abstract The experiment was conducted to investigate the effects of antibiotics on growth performance, diarrhea, fecal β-hemolytic coliforms, and bacterial translocation of weaned pigs experimentally infected with F18 Escherichia coli (E. coli). Twenty-six pigs (6.88 ± 1.03 kg BW) were individually housed in disease containment rooms and randomly allotted to one of three treatments with 8–9 replicate pigs per treatment. The three dietary treatments were control diet and 2 additional diets supplemented with 0.5 or 50 mg/kg carbadox, respectively. The experiment lasted 18 d (7 d before and 11 d after first inoculation [d 0]). F18 E. coli inoculum was daily and orally as 1010 cfu/3 mL for 3 days. Growth performance was measured on d -7 to 0 before inoculation, and d 0 to 5 and 5 to 11 post-inoculation (PI). Diarrhea scores were daily checked throughout the experiment. Fecal samples were collected on d 2, 5, 8, and 11 PI to test the percentage of β-hemolytic coliforms in total coliforms. Bacterial translocation was measured in lymph nodes on d 5 and 11 PI. All data were analyzed by ANOVA using PROC MIXED of SAS. Pigs supplemented with high-dose of antibiotics had greater (P < 0.05) final BW and lower (P < 0.05) overall frequency of diarrhea, compared with pigs in control and low-dose antibiotics groups. Pigs supplemented with low-dose antibiotics had lowest (P < 0.05) ADG and feed efficiency from d 0 to 5 PI, and had highest (P < 0.05) percentage of β-hemolytic coliforms in fecal samples on d 2 and 5 PI, and greatest (P < 0.05) bacterial colonies in mesenteric lymph nodes on d 11 PI, compared with pigs in the other two groups. In conclusion, low dose antibiotic supplementation exacerbates the detrimental effects of E. coli infection on pig performance and diarrhea.

The aim of this study was to investigate effects of lambda-cyhalothrin (LCT) on clinical, hematological, biochemical and pathological alterations in rabbits (Oryctolagus cuniculus). New Zealand white female rabbits (n = 24) of 4-5 months age having 997.92 ± 32.83 g weight were divided into four equal groups. Group A (control) received normal saline intraperitoneally (ip). Animals in groups B, C and D were treated with LCT 1.0, 4.0 and 8.0 mg/kg bw ip. Each group received seven consecutive doses at an interval of 48 hours. Blood and serum samples were collected at an interval of 96 hours. Blood analysis revealed a significant (p < 0.05) decrease in red blood cell and white blood cell counts, hemoglobin concentration and lymphocytes, while mean corpuscular hemoglobin concentration, mean corpuscular volume, neutrophils, monocytes and eosinophils were increased. Serum biochemical analysis revealed significant (p < 0.05) decrease in serum total proteins and serum albumin, while an increase was seen in serum alanine aminotransferase and aspartate aminotransferase activities compared with the control group. Serum globulin values varied non-significantly in all treatment groups as compared to control group. A dose-dependent increase in the incidence of micronucleated polychromatic erythrocyte was observed. All gross and histopathological lesions observed in LCT-treated rabbits were dose-dependent. Liver of the treated rabbits exhibited extensive perihepatitis, hyperplasia of bile duct, necrosis, hemorrhages and congestion. In lungs, there were hemorrhages, thickened alveolar walls, congestion, emphysema, collapsed alveoli and accumulation of extensive inflammatory cells. Kidneys were congested and hemorrhagic whereas renal parenchyma and stroma were normal. Microscopically, heart showed congestion of blood vessels and nuclear pyknosis, myodegeneration. It was concluded from the study that LCT produced toxicopathological alterations in rabbits in a dose-dependent manner. On the basis of the results, it can be suggested that overdosing of LCT be avoided while treating animals for ectoparasites.

Farming of native carnivore fish species has drawn attention due to their promising use in aquaculture. Among these species, tucunaré of the genus Cichla stand out, them being of high economical interest for sport fishing and Amazon's industry of ornamental fish. The present study describes the weight-length relationship (WLR), relative condition factor (Kn), red blood cell parameters, thrombocytes and leukocytes count of Cichla temensis Humboldt, 1821, farmed in central Amazon. Fish that underwent food training during fingerling culture received extruded ration containing 45% of crude protein during fattening, and had Kn with values from 0.925-1.199, which indicated good health condition during the culture. The equation obtained from the WLR was W = 0.0073Lt3.1435, indicating an isometric growth, which is the desirable for fish of fish farm. Red blood cell counts, total thrombocyte and leukocyte counts, hematocrit, hemoglobin concentration, mean corpuscular volume (MCV), concentration of mean corpuscular hemoglobin (MCHC), lymphocytes, monocytes and neutrophils had intra-specific variation. A significant (p<0.001) positive correlation of the red blood cells number with the hemoglobin concentration and hematocrit was found. These are the first sets of blood parameters for C. temensis and could be used as reference for comparison in further studies to evaluate the health status of this fish in different environments, because assessment of these parameters may be used as quick tool for diagnosing diseases, stress and malnutrition.

Abstract The objective of this experiment was to investigate dietary supplementation of oligosaccharide-based polymer on blood profiles of weaned pigs experimentally infected with a pathogenic F18 Escherichia coli (E. coli). Forty-eight pigs (7.23 ± 1.11 kg BW) were individually housed in disease containment rooms and randomly allotted to one of four treatments with 12 replicate pigs per treatment. The four dietary treatments were a nursery basal diet (control), and 3 additional diets supplemented with 50 mg/kg Mecadox (AGP), 10 or 20 mg/kg of oligosaccharide-based polymer. The experiment lasted 18 d [7 d before and 11 d after the first inoculation (d 0)]. The doses of F18 E. coli inoculum were 1010 cfu/3 mL oral dose daily for 3 days. Blood samples were collected before E. coli inoculation (d 0), and on d 2, 5, 8, and 11 post-inoculation (PI). Total and differential blood cell count were analyzed by CBC test. All data were analyzed by ANOVA using the PROC MIXED of SAS with pig as the experimental unit. Supplementation of oligosaccharide-based polymer linearly (P &lt; 0.05) reduced white blood cell counts, neutrophils, eosinophils, and basophils on d 2 PI, and neutrophils on d 5 PI, compared with the control. No differences were observed in total and differential white blood cell counts among AGP and two oligosaccharide-based polymer treatments except that pigs fed with AGP had greater (P &lt; 0.05) lymphocytes on d 2 PI compared with pigs fed with oligosaccharide-based polymer diets. Supplementation of low dose oligosaccharide-based polymer or AGP reduced (P &lt; 0.05) red blood cell count and packed cell volume on d 2 PI, whereas inclusion of high dose oligosaccharide-based polymer or AGP reduced (P &lt; 0.05) packed cell volume on d 5 PI, compared with the control. In conclusion, supplementation of oligosaccharide-based polymer may alleviate the systemic inflammation caused by F18 E. coli infection.

Abstract Our previous studies have shown that exposure to low-dose antibiotic growth promoter (AGP) may exacerbate the negative effects of Escherichia coli (E. coli) infection on weaned pigs. The objective of this experiment was to investigate the effects of low-dose AGP on serum metabolomic profiles of weaned pigs experimentally infected with F18 E. coli. Thirty-four pigs (6.88 ± 1.03 kg BW) were individually housed in disease containment rooms and randomly allotted to one of three treatments with 9–13 replicate pigs per treatment. The three dietary treatments were control diet (control) and 2 additional diets supplemented with 0.5 or 50 mg/kg of AGP (carbadox), respectively. The experiment lasted 18 d [7 d before and 11 d after first inoculation (d 0)]. The F18 E. coli inoculum was orally provided to all pigs with the dose of 1010 cfu/3 mL for 3 consecutive days. Blood samples were collected on d 0 before E. coli inoculation and on d 5 and 11 post-inoculation (PI). Serum metabolomics were analyzed for untargeted metabolomics by gas chromatography-time of flight-mass spectrometer (GC-TOF-MS). All processed data were statistically analyzed and evaluated by online MetaboAnalyst tool. No significant differences were observed in serum metabolites between control and low-dose AGP throughout the experiment. Supplementation of high-dose AGP changed the concentrations of several serum metabolites (P &lt; 0.05; arabitol, guanine, and xylitol) compared with control pigs on d 5 PI. Further metabolic pathway enrichment analysis showed that low-dose AGP modified (P &lt; 0.05) pentose phosphate pathway, DNA synthesis in T and B lymphocytes, bile acid metabolism, and amino acid metabolism in E. coli infected pigs, compared with high-dose AGP. In conclusion, the modification of serum metabolites and metabolic pathways by low-dose AGP may be involved in reduced growth performance, exacerbated diarrhea and systemic inflammation of weaned pigs induced by E. coli infection.

Abstract The objective of this study was to investigate the effects of dietary botanical supplementation on blood profiles and intestinal morphology of weaned piglets experimentally infected with a pathogenic F18 Escherichia coli (E. coli). Sixty weaned piglets (around 21 days old; 7.15 ± 0.97 kg) were individually housed and randomly allotted to one of five dietary treatments (n = 12): negative control (NC), positive control (PC), high dose of botanicals blend 1 (BB1, 100 mg/kg), and low or high dose of botanicals blend 2 (BB2, 50 mg/kg and 100 mg/kg). The experiment lasted 28 days: from day -7 to +21 relative to E. coli inoculation. All piglets except the NC group were orally inoculated with F18 E. coli (10 cfu per dose, 3 doses) for 3 consecutive days. Blood samples were collected on d 0, 5, 14, and 21 post-inoculation (PI) to perform complete blood count test. Intestinal segments were collected on d 5 and 21 PI for intestinal morphology analysis. Data were analyzed by ANOVA using PROC MIXED of SAS with a randomized complete block design. E. coli infection reduced (P &lt; 0.05) neutrophils and lymphocytes, but increased (P &lt; 0.05) monocytes on d 4 PI. Pigs supplemented with 100 mg/kg BB2 had less (P &lt; 0.05) lymphocytes than pigs in PC on d 4 PI. Pigs fed with 50 mg/kg BB2 had lower (P &lt; 0.05) lymphocytes and monocytes then pigs in PC on d 21 PI. Pigs supplemented with 100 mg/kg BB2 had the greatest (P &lt; 0.05) duodenal villi width, jejunum villi height and area, and colon crypt depth then pigs in PC on d 5 PI. In conclusion, dietary supplementation of botanicals tended to affect systemic immunity and enhance intestinal morphology of weaned pigs infected with E. coli.

Abstract Our previous studies have shown that supplementation of low-dose antibiotic growth promoter (AGP) exacerbated growth performance and systemic inflammation of weaned pigs infected with pathogenic Escherichia coli (E. coli). The objective of this experiment, which is extension of our previous report, was to investigate the effect of low-dose AGP on gene expression in ileal mucosa of weaned pigs experimentally infected with F18 E. coli. Thirty-four pigs (6.88 ± 1.03 kg BW) were individually housed in disease containment rooms and randomly allotted to one of three treatments (9 to 13 pigs/treatment). The three dietary treatments were control diet (control), and 2 additional diets supplemented with 0.5 or 50 mg/kg of AGP (carbadox), respectively. The experiment lasted 18 d [7 d before and 11 d after first inoculation (d 0)]. The F18 E. coli inoculum was orally provided to all pigs with the dose of 1010 cfu/3 mL for 3 consecutive days. Total RNA [4 to 6 pigs/treatment on d 5; 5 to 7 pigs/treatment on 11 post-inoculation (PI)] was extracted from ileal mucosa to analyze gene expression profiles by Batch-Tag-Seq. The modulated differential gene expression were defined by 1.5-fold difference and a cutoff of P &lt; 0.05 using limma-voom package. All processed data were statistically analyzed and evaluated by PANTHER classification system to determine the biological process function of genes in these lists. Compared to control, supplementation of recommended-dose AGP down-regulated genes related to inflammatory responses on d 5 and 11 PI; whereas, feeding low-dose AGP up-regulated genes associated with negative regulation of metabolic process on d 5, but down-regulated the genes related to immune responses on d 11 PI. The present observations support adverse effects of low-dose AGP in our previous study, indicated by exacerbated the detrimental effects of E. coli infection on pigs’ growth rate, diarrhea and systemic inflammation.

Abstract Developments of pulmonary diseases, often accompanied by infections of bacteria, severely affect the meat production and welfare of pigs. This study investigated 307 pigs at age of 240 d from an eight-breed cross reared under standardized housing conditions for associations among the extent of lung lesions, bacteria load inferred from 16S rRNA sequencing of bronchoalveolar lavage fluid, as well as 57 immune cells and 25 hematological traits. We showed that the pigs under study suffered substantial and varied lung lesions, and the Mycoplasma is the most associated bacteria genera. At a false discovery rate of 0.05 (FDR &lt; 0.05), the severity of lung lesions were significantly associated with greater CD8+ to CD3+ cell ratio, neutrophil-to-lymphocyte ratio (NLR), and standard deviation of red blood cell volume distribution width (RDW-SD), and lower CD4−CD8−/CD3+, CD3+CD4−CD8−/PBMCs (peripheral blood mononuclear cells) and CD14−CD16−/PBMCs cell ratios, mean corpuscular hemoglobin concentration, lymphocyte count, and lymphocyte count percentage, reflecting an status of inflammation, immune suppression, and hypoxia of the pigs accompanying the progression of the lung lesions. The Mycoplasma abundance showed positive correlations with neutrophil count, neutrophil count percentage, NLR, monocyte count, coefficient of variation in red blood cell volume distribution width , and RDW-SD, and negative correlations with mean corpuscular hemoglobin concentration, lymphocyte count, and lymphocyte count percentage; these correlations are largely consistent with those of lung lesions, supporting the comorbidity of lung lesions and Mycoplasma infection. We also observed nonlinear associations that sharp increases in neutrophil count and neutrophil count percentage occurred only when Mycoplasma abundance raised above the population-average level. The results provide helpful insights into the changes of host immune status in response to Mycoplasma relevant lung diseases in pigs.

Peripheral blood cells (PBCs) collected by leukapheresis after progenitor mobilization with chemotherapy and growth factors have been used successfully to replace marrow autografts in protocols requiring stem-cell support. Moreover, such transplants are often associated with more rapid recovery of blood cell counts than is routinely achieved with bone marrow. While conditions that mobilize colony-forming cells (CFCs) into the circulation are becoming increasingly well characterized, little information is available as to how these or other mobilizing treatments may influence the release of more primitive cells into the peripheral blood. To quantitate the peripheral blood content of such cells, we used the long-term culture-initiating cell (LTC-IC) assay, which detects a cell type that is able to produce progeny CFCs after a minimum of 5 weeks in cultures containing marrow fibroblasts. In this report, we present the findings on 21 patients who were transplanted over a 7-year period at our institution with PBCs alone. PBCs were collected in steady-state (n = 6) or during the recovery phase after high-dose cyclophosphamide (Cy; n = 15, nine with and six without additional growth factor administration). PBCs collected from another 11 patients given granulocyte colony-stimulating factor (G-CSF) were transplanted together with autologous marrow. Time-course studies of nine patients after Cy +/- granulocyte-macrophage CSF (GM-CSF) showed that CD34+ cells, CFCs, and LTC-ICs fell from normal to undetectable levels after Cy, and increased at the time of white blood cell (WBC) recovery: LTC-ICs to a mean of sixfold and CFCs to a mean of 26-fold higher than normal. The mean number of CD34+ cells, CFCs, and LTC-ICs present in the PBC harvest was twofold to 10-fold higher after mobilization than in steady-state collections; however, more than 2-log interpatient variability was observed. After PBC transplantation, the median time to a WBC count more than 10(9)/L was 12 days; polymorphonuclear leukocyte (PMN) count more than 0.5 x 10(9)/L, 15 days; and platelet count more than 20 x 10(9)/L, 17 days, although patients who received fewer than 1.5 x 10(5) CFCs/kg had a more than 50% chance of delayed count recovery (> 28 days). Patients who received Cy + GM-CSF-stimulated PBCs had more rapid and consistent platelet recoveries as compared with other groups receiving Cy mobilized or steady-state PBCs alone, and a rapid WBC recovery after Cy predicted a rapid WBC recovery after transplantation.

ABSTRACT Objective: The objective was to determine the basic hematological parameters of remunerated blood donors in Benin City and to compare them with those of voluntary donors. Materials and Methods: This is a prospective study conducted in a tertiary health facility in Benin City. Pretransfusion samples were obtained from blood bags after gentle mixing and analyzed for hematological parameters. Samples were analyzed using the hematology autoanalyzer MODEL SYSMEX KN21. Result: A total of 215 samples were obtained comprising 160 remunerated (paid) and 55 voluntary donor samples. In the paid donors, the mean hemoglobin concentration (Hb) and hematocrit (HCT) 7.7±2.9 and 28.8±8.5 respectively. This was significantly lower than those of voluntary donors who had 13.9±1.2 and 42.2±3.3 with P < 0.001. The mean values of the red cell counts (RBC), white cell counts (WBC), mean cell volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were significantly lower in paid donors as P-values were <0.001. MCV was significantly low but not compared to the other parameters as P=0.04. There was no significant difference in the platelet count. Conclusion: Paid donors in Benin City have significantly lower hematological parameters than controls.
