Packed-cell volume, sedimentation rate, hemoglobin, red blood cell count, white blood cell count, differential count, and red cell diameter have been determined on blood samples taken from 22 beavers. The various values obtained are in general comparable with those reported for the other rodents. Exceptions to this general agreement were noted in the much higher sedimentation rate and slightly larger red cell diameter of beaver blood.

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 < 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 < 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 < 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 < 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.

Sheep were used to compare the anemia effects of fresh marrow-stem kale (Brassica oleracea var. acephala D.C.) with low-temperature dehydrated marrow-stem kale (MSK). There was a drop in hemoglobin (P < 0.01), packed-cell volume (P < 0.05), and red blood cell count (P < 0.05) after the 4th, 5th, and 6th wk, respectively, of feeding fresh MSK. Similar drops in hemoglobin (P < 0.05), packed-cell volume (P < 0.05), and red cell count (P < 0.05) occurred after the 4th wk of feeding dried MSK. Formation of Heinz-Ehrlich bodies peaked at the corresponding lowest values of hemoglobin and packed-cell volume for both fresh and dried MSK. These criteria returned almost to normal in the 2nd and 3rd wk after stopping the feeding of kale and using ground hay as the entire ration instead. It was concluded that high levels of either fresh or dried MSK could not be fed to sheep even for a relatively short period of time.

Saccharomyces boulardii is a probiotic yeast used as a nutritional supplement. Co-trimoxazole, is a broad-spectrum antimicrobial agent used in the prophylaxis and treatment of infections.The goal of this study was to evaluate the individual and interactive effects of probiotic Saccharomyces boulardii and co-trimoxazole on some haematological parameters in albino rats. Thirty (30) albino Wistar rats weighing 150-200g were divided into five groups; Basal, A, B, C, and D, with six animals in each group. Group A (control) was given a normal rat pellet (standardized feed) and clean water (pH 6.5- 8.5). Group B was administered 5.5mg/kg body weight of the commercial probiotics (Saccharomyces boulardii). Group C was administered 4.4mg/kg body weight of co-trimoxazole. Group D was administered 5.5mg/kg body weight of the commercial probiotics and 4.4mg/kg body weight of co-trimoxazole. All administrations were done using a gavage tube for 15 days. Blood samples were collected for analysis on days 0, 5 and 15. The results showed that Saccharomyces boulardii caused a significant increase (P<0.05) in total white blood cell count and packed cell volume of the treated groups at day 5. On day 15, the total white blood cell count (10.67±0.66), packed cell volume (43.23±0.47), platelet count (932±38.89) and mean platelet volume (8.53±0.38) showed a significant increase (P<0.05) in the probiotic group. The co-trimoxazole group showed a significant reduction (P<0.05) in the packed cell volume and total white blood cell count. This study shows that Saccharomyces boulardii has a positive effect on the haematological profile of the test animals.

Reptiles, especially turtles, are becoming increasingly popular as pets. The haematological evaluation of turtles is an irreplaceable diagnostic tool in veterinary practice. However, the morphologic distinctiveness of turtle blood limits the use of electronic cell-counting devices, making time-consuming, manual counting techniques and evaluation of blood smears necessary. Many samples are dispatched to a laboratory over long distances, where a delay of 24 h or more may occur. At weekends, this interval may exceed 48 h. The objective of the present study was to determine the effect of storage duration at refrigerator temperature (4 °C) on the counts of red blood cells (RBC) and white blood cells (WBC), and on the mean corpuscular volume (MCV) and packed cell volume (PCV) in blood samples from healthy adult red-eared sliders. Blood samples were collected by venipuncture from the occipital venous sinus from six apparently healthy adult red-eared sliders, aged 2 to 4 years. Blood samples were analysed immediately after sampling to obtain the baseline value (BV) of the red blood cell count, white blood cell count and packed cell volume percentage. Blood was stored at 4 °C and the haematological analyses were performed after 24h, 48h and 72h. The results showed the same level of stability for RBC and WBC count, and MCV values during 72 hours of storage at 4 °C and for PCV during 48 hours. Handling of blood samples, and duration of storage of the blood samples can significantly influence the results/values of haematological tests. Consequently, the obtained values of the determined haematological parameters of improperly stored or handled blood samples can give a misleading interpretation of the results on the animal’s health status.

The haematology of a colony of wild allied rock-wallabies, Petrogale assimilis Ramsay, 1877, from north-western Queensland was studied for 20 months. Wallabies were repeatedly trapped at monthly intervals and 511 blood samples from 96 animals were examined, making this the most comprehensive study of the haematology of any macropod species. The morphology of the red blood cells and leucocytes was similar to those of other marsupials. Large and small lymphocytes were recognised. Binucleate lymphocytes were found in 7.2% of blood smears. Normal haematological values were within the published ranges for other marsupials. However, the average white blood cell count (mean +/- s.e.: 9.03 +/- 0.92 X 10(9) L-1) was close to the upper end of the range for macropods. The normal (mean +/- s.e.) red blood cell count (5.24 + 0.15 X 10(12) L-1), packed cell volume (0.4291 +/- 0.019 L L-1) and haemoglobin concentration (14.07 +/- 0.41 g dL-1) of male wallabies were higher than those of females (4.79 +/- 0.15 X 10(12) L-1, 0.3952 +/- 1.19 L L-1, and 12.95 +/- 0.41 g dL-1, respectively). No gender differences were detected in the white blood cell count (9.03 +/- 0.92 x 10(9) L-1), mean corpuscular volume (82.28 +/- 1.35 fL), mean corpuscular haemoglobin (26.98 +/- 0.57 pg) or mean corpuscular haemoglobin concentration (32.82 +/- 0.57 g L 1). The red blood cell count, packed cell volume, haemoglobin concentration, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration and the absolute neutrophil count in juveniles and subadults increased with age. The neutrophil to lymphocyte ratio was less than 1.0 in pouch young and approached 1.0 in adults. The red blood cell count, packed cell volume and haemoglobin concentration of lactating females did not vary with age of pounch young.

AbstractThis study evaluated inter- and intra-observer variabilities of band cell and atypical lymphocyte differentials and the influence of instrument flagging information on resulting microscopic differentials. Five stained slides with a range of band cell counts and five with variable numbers of atypical lymphocytes were sent for morphological review by 30 technicians. No supplementary full blood cell count information was provided. Two months later, the same slides were sent, together with their corresponding analyzer reports comprising the full blood cell count, automated differentials and flags, to the same technicians. The first and second appraisals of band cells and variant lymphocytes both showed poor levels of inter-observer consistency. Observed values for all slides were very wide and suggested a high inherent predisposition to erroneous reporting practices. Analysis of category trends showed that analyzer left shift or immature granulocytes flags had no influence on observer band cell assessments as downward vs. upward category revisions were evenly balanced. The findings for atypical lymphocytes were, however, somewhat different. Two slides with no flags both showed balanced category revisions, whereas two of the three slides with atypical lymphocyte flags showed clear evidence of upward category revision. The third slide with an atypical lymphocyte flag did not show any overall category trend, but six of the seven observers who in the first examination recorded atypical lymphocyte estimates of ≤30% revised their estimates upward when the slides were examined the second time. These results suggest that morphologist access to an analyzer report and flagging information is unlikely to affect the “randomness” of band cell determinations but it may induce observer bias in variant lymphocyte estimates.

Introduction. In general, chronic wounds are colonized by bacteria; however, when microorganisms start to multiply at higher levels, wounds can become infected, causing prolongation of the inflammatory phase and retardation of collagen synthesis and epithelialization. Objective. The objective of this study was to evaluate the presence of infection in venous ulcers after 12 weeks of treatment with autologous platelet-rich plasma (PRP) and determine global white blood cell counts. Materials and Methods. This case series study involved a sequential sample of 17 patients with venous ulcers treated with PRP for 12 weeks. Descriptive and inferential statistical analysis was performed using the McNemar test and χ² test. Results. At baseline, 10 patients (58.8%) had wound infection. During the sixth week of treatment with PRP, only 3 patients (17.6%) continued to exhibit wound infection. After 12 weeks of PRP treatment, only 1 patient (5.9%) continued to exhibit wound infection. McNemar and χ² tests used to assess the presence of infection in the intervention group produced a P value of .0039 for a comparison of baseline and week 6 and a P value of .0078 for a comparison of baseline and week 12. These results demonstrated significant differences from baseline at both 6 weeks and 12 weeks of treatment, with greater significance at 12 weeks. There was no relationship between global white blood cell count and the presence of infection. Conclusion. After intervention with PRP, 94% of patients experienced improvement concerning the infection of ulcers.
