Normal serum biochemical and hematological values of the Sulawesi macaques

Sulawesi macaque (SM) species are currently of interest to primatologists for genetic and behavioral studies world wide. However, there are no published reference hematological and serum biochemical profile values for several of the seven SM species. Twenty-five clinically healthy, outdoor housed, ketamine sedated Macaca tonkeana and Macaca maurus were serially sampled (two to four times) over a 16-month period (N = 68). Normal ranges were defined to include two standard deviations and 2.5–97.5 percentile. Significant differences in single sample date comparisons (P < 0.05) of species (serum Ca, MCHC), age (BUN, BUN/creatinine, alkaline phosphatase, phosphorus), gender (total protein, RBC, hemoglobin, HCT) and pregnancy (phosphorus and neutrophil count) groups were found. This normative data facilitates clinical evaluation of SM species and allows comparison to other macaque species.     

Hematological and plasma biochemical values for captive tufted capuchin monkeys (Cebus apella)

Hematological and blood biochemical parameters are of great importance in medical and veterinary practice. Unfortunately, normal reference range intervals for hematological and serum biochemical values in the tufted capuchin monkey (Cebus apella) have seldom been reported. The study reported here is based on data from blood samples collected from 44 monkeys over an 8-year period. Male and female data are displayed separately within two age categories: juveniles and adults, and effects for sex and age are examined. Significant differences between males and females are found for erythrocytes, hemoglobin, hematocrit, and α(1) globulin. Significant differences between juveniles and adults are found for neutrophils, calcium, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, inorganic phosphorus, glucose, total protein, serum iron, and some serum protein parameters and albumin/globulin ratio. These values are compared with values we previously reported, and their importance in care and well-being of captive tufted capuchin monkeys is discussed.     

Clinical Biochemistry and Hematology of the Elusive Sun‐Tailed Monkey (Cercopithecus solatus) in Gabon: Inaugural Data From the Only Semifree Ranging Colony in the World

Clinical blood biochemistry and hematology are valuable tools to evaluate health and welfare in many animal species. In order to document the general biology of one of the most poorly known nonhuman primate species, and contribute to its conservation, the clinical blood biochemistry and hematology of the sun‐tailed monkey (Cercopithecus solatus Harrisson) was investigated in its range of endemicity in Gabon. Data derived from 26 years of clinical monitoring of the only semicaptive colony of this species in the world, housed at CIRMF (Franceville, Gabon), were analyzed in order to establish reference values of age–sex classes. Consistent with previous reports in other primate species, age and sex significantly affected a number of biochemical and hematological parameters in C. solatus. Hematological analyses demonstrated significant differences in red blood cells, hemoglobin (HB), and hematocrit (HT), with males showing significantly greater values than females. In contrast, neutrophil counts were greater in females. An ontogenetic effect was detected for HB, HT, eosinophil, and monocyte counts, while lymphocytes significantly decreased with age. Biochemical analyses also showed significant differences, with females displaying greater cholesterol and alanine aminotransferase levels. Increase in levels of blood urea and aspartate aminotransferase coupled with decrease in albumin in old individuals suggested declining kidney, liver, and muscle functions with age. Interspecific comparisons were conducted and the effects of the unique semifree‐ranging setting on the validity and value of the results presented are discussed. The reference values established will be useful in further ecological, parasitological, and virological studies of the sun‐tailed monkey.

Reference values for biochemical parameters in blood serum of young and adult alpacas (Vicugna pacos)

The aim of this study was to establish reference interval for biochemical parameters in blood of alpacas on the basis of large population of clinically healthy animals, and to determine the influence of sex, age and season on nitrogen and lipid metabolites, enzymes, electrolytes, vitamins and minerals in blood of alpacas. Blood samples were collected from 311 alpacas (61 males and 201 females >6 months of age and 49 crias (21 males and 28 females) ⩽6 months of age). Selected farms were located in Central Europe (Czech Republic and Germany). We determined 24 biochemical parameters from blood serum. We performed the comparison of results by the sex of animals and for the older group also the comparison of the results with regard to the season, respectively, to the feeding period. We found no highly significant difference (P<0.01) between males and females with the exception of γ-glutamyl transferase (GGT), alkaline phosphatase (ALP) and cholesterol. We found 15 significantly different parameters between the group of crias 6 months of age and the older alpacas. Based on our findings we suggest for most parameters to use different reference intervals (especially ALP, cholesterol, total protein, globulin, non-esterified fatty acids (NEFA), GGT and phosphorus) for the two above-mentioned age groups. Another important finding is the differences between some parameters in older group of alpacas in summer/winter feeding period. Animals in the summer feeding period have higher values of parameters related to fat mobilization (β-hydroxybutyrate, NEFA) and liver metabolism (bilirubin, alanine aminotransferase). The winter period with increased feeding of supplements with higher amount of fat, vitamins and minerals is characteristic by increased values of cholesterol, triglycerides, vitamins A and E, and some minerals (K, Ca, Mg and Cl) in blood serum. Clinical laboratory diagnosis of metabolic disturbances may be improved with use of age-based reference values and with consideration of seasonal differences.     

Biochemical and white blood cell profiles of baboon neonates consuming formulas with moderate and high dietary long-chain polyunsaturated fatty acids

BACKGROUND: Clinical chemistry and complete blood count (CBC) values were determined in 14 term baboons (Papio species) consuming formula with moderate or high levels of dietary long-chain polyunsaturated fatty acids (LCPUFA) from 2-12 weeks of age. METHOD: Neonates were randomized to three groups: C: Control, no LCPUFA; L: 0.33% docosahexaenoic acid (DHA)/0.67% arachidonic acid (ARA) (w/w); L3:1.00% DHA/0.67% ARA (w/w). Blood chemistries were assessed at 6 and 12 weeks and CBC parameters were measured at 2, 4, 8, 10, 12 weeks of age. RESULTS: Dietary LCPUFA had significant effects on serum triglyceride (C > L,L3) and calcium (L > C,L3). No other significant effects of diet were detected; pooled values are presented for all other parameters. CONCLUSION: These data provide longitudinal biochemical and white cell/platelet/immunological data on LCPUFA-fed baboons over the first 12 weeks of life. Data ranges are similar to reference data in cases for which values exist and hematological changes reflect trends observed during human neonatal development.     

Reference values of hematological, serum biochemical and hormonal examinations in female cynomolgus monkeys (Macaca fascicularis) of feral origin

Blood samples were collected from clinically healthy female cynomolgus monkeys imported from Indonesia, the Philippines and Malaysia. These animals were maintained under uniform environmental conditions for four to five years. The blood samples were examined for their hematological, serum biochemical and hormonal values. The ranges of the values as well as their arithmetic means and standard deviations have been tabulated with respect to each examination item.     

Blood groups of bonnet macaques (Macaca radiata), with a brief introduction to seroprimatology

The human-type A-B-O blood groups of 52 bonnet macaques (Macaca radiata) were determined. Application of method of population genetics indicated the gene frequences to be O = 0.173, A = 0.480 and B = 0.347. Cross testing of sera and red cells of the bonnet macaques revealed two blood-type-specific isoagglutinins, one of them strong enough for use as a blood typing reagent. No blood group polymorphism was revealed by testing bonnet macaque red cells with isoantisera produced in rhesus monkeys (M. mulatta) and in crab-eating macaques (M. fascicularis). The rhesus and crab-eating macaque isoantisera reacted either with all or with none of the bonnet macaque red cells tested.     

Haematology and blood chemistry of Cebus apella in relation to sex and age

An effective health care program entails the prevention, diagnosis and treatment of medical problems. A knowledge of baseline values in clinically normal individuals is essential for determining the limits between good health and disease and for understanding the changes produced by pathogenic agents. However, very little information is currently available concerning the blood chemistry and haematological values of different species of monkeys, particularly new-world primates. The values of some haematological and chemical parameters in Cebus apella were determined. The aim of the present work was to verify the effect of age and sex on normal blood values. Blood samples were collected once a year for two successive years from 36 monkeys living in large captive social groups. Significant differences between males and females were found for AST, GGT, urea nitrogen and creatinine, erythrocytes, haemoglobin and haematocrit. Significant differences between juveniles and adults were found for calcium, AST, alkaline phosphatase, inorganic phosphorus, glucose, neutrophils, lymphocytes and serum protein parameters.     

Haematological and biochemical reference intervals for farmed channel catfish

The reference intervals for biochemical variables and red blood cell indices of healthy intensively bred channel catfish Ictalurus punctatus were determined. The blood variables were determined using standardized clinical methods. The reference intervals (25th and 75th percentiles) were established using a non-parametric method. Reference intervals for plasma glucose, serum total protein, sodium, potassium, calcium, magnesium, chloride concentration, primary and secondary red blood cell indices were established. The haematological and biochemical reference intervals established may allow important clinical decisions about channel catfish.

Species differences in the interest shown in infants by juvenile female macaques (Macaca radiata andM. mulatta)

Using a focal animal technique, 16 juvenile female rhesus and bonnet macaques (2–3 years old) were observed with respect to the frequency and duration of their contacts with infants (0–1 year old). Each of these subjects was a member of one of four seminatural groups of macaques housed in 0.5-acre field cages at the California Primate Research Center. Rhesus juvenile females became very interested in infants when the latter were quite young, and maintained that interest throughout the study. When the infants were approximately 3–4 months old, the rhesus juveniles spent, on the average, 3.9 min/hr with those infants. By the time the infants were yearlings, the time spent with infants was approximately 6 min/hr. Relative to the rhesus, the bonnet juveniles showed less interest (about 2.2 min/hr) in young (3- to 4- month-old) infants, although by the time the infants were yearlings, the bonnets spent about 5.6 min/hr with them. Rhesus juveniles preferred sibling over nonsibling infants, but the presence of a sibling was not a necessary requirement for infant-directed behavior. The two bonnet juveniles who had infant siblings showed no preference for the latter. These data were interpreted within the framework of Quiatt’s [(1979) Am. Anthropol. 81: 310–319 conclusions about allomaternal behavior. Specifically, it was argued that, to the extent that there are species differences in maternal behavior, there should also be species differences in allomaternal behavior. The species differences in the maternal styles of rhesus and bonnet macaques provide a basis for an examination of this hypothesis.     

Population-based biochemistry, immunologic and hematological reference values for adolescents and young adults in a rural population in Western Kenya

Background

There is need for locally-derived age-specific clinical laboratory reference ranges of healthy Africans in sub-Saharan Africa. Reference values from North American and European populations are being used for African subjects despite previous studies showing significant differences. Our aim was to establish clinical laboratory reference values for African adolescents and young adults that can be used in clinical trials and for patient management.

Methods and Findings

A panel of 298, HIV-seronegative individuals aged 13–34 years was randomly selected from participants in two population-based cross-sectional surveys assessing HIV prevalence and other sexually transmitted infections in western Kenya. The adolescent (<18 years)-to-adults (≥18 years) ratio and the male-to-female ratio was 1∶1. Median and 95% reference ranges were calculated for immunohematological and biochemistry values. Compared with U.S-derived reference ranges, we detected lower hemoglobin (HB), hematocrit (HCT), red blood cells (RBC), mean corpuscular volume (MCV), neutrophil, glucose, and blood urea nitrogen values but elevated eosinophil and total bilirubin values. Significant gender variation was observed in hematological parameters in addition to T-bilirubin and creatinine indices in all age groups, AST in the younger and neutrophil, platelet and CD4 indices among the older age group. Age variation was also observed, mainly in hematological parameters among males. Applying U.S. NIH Division of AIDS (DAIDS) toxicity grading to our results, 40% of otherwise healthy study participants were classified as having an abnormal laboratory parameter (grade 1–4) which would exclude them from participating in clinical trials.

Conclusion

Hematological and biochemistry reference values from African population differ from those derived from a North American population, showing the need to develop region-specific reference values. Our data also show variations in hematological indices between adolescent and adult males which should be considered when developing reference ranges. This study provides the first locally-derived clinical laboratory reference ranges for adolescents and young adults in western Kenya.     

Outcast males and social structure among bonnet macaques (Macaca radiata)

Outcast males are a regular feature of rhesus (Macaca mulatta) and Japanese (M. fuscata) macaque societies but are rare among bonnet macaques (M. radiata). Apparently bonnets have other solutions than ostracism for their social problems. For example, in many troops the male-female ratio ranges from 0.7?1.0+; and, as the young adult males grow to full social and physical maturity, they remain in the troop and participate actively in social relationships. A few troops of bonnet macaques, however, have a network of social relationships which prevents the young males from being integrated into the social system; in some of these cases, male isolation occurs. A comparison of the social relations between males in bonnet macaque societies of both types suggests that societies with strong male-male bonds accommodate their growing males better than those with highly individual males.     

Effects of serial anesthesia using ketamine or ketamine/medetomidine on hematology and serum biochemistry values in rhesus macaques (Macaca Mulatta)

Background  This study aimed at determining the cumulative effect of daily anesthesia, using two drug regimens, over hematological and biochemical parameters.
Methods  Blood samples were obtained from rhesus monkeys 20 minutes after intramuscular administration of ketamine or ketamine/medetomidine combination for three consecutive days and results were evaluated to determine their effect on hematological and serum biochemistry values. Statistical significance of drug, day, and interaction of these two variables were evaluated.
Results  Drug effect resulted in a dramatic increase of aspartate aminotransferase and creatine kinase values. Day effect resulted in decreases of RBC, HCT, Hgb, and alkaline phosphatase but an increase of other biochemical parameters evaluated. The drug/day interaction effect was found to be –significant for RBC, platelets, aspartate aminotransferase, alanine aminotransferase, and creatine kinase values.
Conclusion  The results of our study suggest a cumulative effect of serial anesthesia and should be an important consideration when interpreting hematology and serum biochemistry in rhesus macaques.     

Hematocrit and blood chemistry values in three genera of captive hornbills

This study reports hematocrit and blood chemistry values for captive adult individuals belonging to three genera of hornbills (Bucerotidae), Aceros, Anthracoceros, and Ceratogymna, and evaluates genera and gender specific differences in these values. Ceratogymna differs significantly from the other two genera in the concentration of total proteins, cholesterol, triglycerides, phosphorus, potassium, and sodium. Blood glucose concentrations in Aceros were lower than those in the other two genera. Plasma levels of enzymes differed between Aceros and Ceratogymna. With respect to gender differences, Aceros males had greater plasma levels of alanine aminotransferase (ALT), calcium and phosphorus than did the females, and the Ceratogymna males had higher concentrations of triglycerides. Body mass was correlated with hematocrit, cholesterol, total proteins, and urea in Aceros and with calcium concentration in Ceratogymna. These results are the first data available on reference ranges of blood values in individuals of this family of birds and may therefore be very useful as a complementary diagnostic tool in the veterinary care of individuals of these species in captivity.

Male–Male Relationships in Lion-tailed Macaques (<Emphasis Type="Italic">Macaca silenus</Emphasis>) and Bonnet Macaques (<Emphasis Type="Italic">Macaca radiata</Emphasis>)

Socioecology suggests that female distribution in space is determined by the distribution of food resources and the male distribution is influenced by female distribution. Though studies have traditionally focused on females, males have received increasing attention in recent years. We compared male–male relationships in lion-tailed macaques and bonnet macaques. Because bonnet macaques have a high adult male:female sex ratio and are seasonal breeders whereas lion-tailed macaques have a low adult male:female sex ratio and are largely aseasonal breeders, we predicted that bonnet macaque males would be spatially and socially more tolerant of each other and would have less linear dominance relationships than lion-tailed macaques. We recorded male–male and male–female relationships in 1 group of wild macaques of each species via scan sampling and 1–0 sampling. The results revealed that lion-tailed macaque males largely remained at a distance from each other whereas bonnet macaque males remained in close proximity to one another. Lion-tailed macaque males were more agonistic toward each other whereas bonnet macaque males showed more affiliative interactions. The dominance hierarchy among lion-tailed macaque males was more linear than among bonnet macaque males. Our data support the hypothesis that the study of spatial structuring, temporality of interactions, and linearity of social relationships may contribute to a better understanding of macaque social systems.     

Reference values for serum chemistry of wild Amazon river dolphins (Inia geoffrensis) from the central Amazon

Blood values of wild cetacean population are a valuable tool to drive proper management of threatened species. Reference intervals of 26 serum analytes were determined from 107 apparently healthy Amazon river dolphins (Inia geoffrensis) wild-caught in the Mamirauá Sustainable Development Reserve (3°3′S, 64°51′W), central Amazon, Brazil. No differences were detected between males and females or between pregnant and nonpregnant females. Calves had higher serum calcium than juveniles and adults, and alkaline phosphatase activity was higher in calves and juveniles than adults as a result of bone growth. Adults showed higher creatinine levels than juveniles due to higher body mass, and higher urea than calves. Positive correlation was found between body length and body weight with creatinine, urea, and alanine aminotransferase activity; whereas calcium and alkaline phosphatase and creatine kinase (CK) activities negatively correlated with these body parameters. Cardiac rate and respiratory frequency appear to have not correlated with any serum analyte, while stress level positively correlated with CK. Storage of frozen samples for 60 days at −80°C significantly altered 10 of the 19 analytes after one freeze–thaw cycle. Important differences were detected among age classes, stress level, and sample storage and should be taken into account before any clinical or physiological interpretations.
