Abstract Background and objectives Among placental mammals, females undergo immunological shifts during pregnancy to accommodate the fetus (i.e. fetal tolerance). Fetal tolerance has primarily been characterized within post-industrial populations experiencing evolutionarily novel conditions (e.g. reduced pathogen exposure), which may shape maternal response to fetal antigens. This study investigates how ecological conditions affect maternal immune status during pregnancy by comparing the direction and magnitude of immunological changes associated with each trimester among the Tsimane (a subsistence population subjected to high pathogen load) and women in the USA. Methodology Data from the Tsimane Health and Life History Project (N = 935) and the National Health and Nutrition Examination Survey (N = 1395) were used to estimate population-specific effects of trimester on differential leukocyte count and C-reactive protein (CRP), a marker of systemic inflammation. Results In both populations, pregnancy was associated with increased neutrophil prevalence, reduced lymphocyte and eosinophil count and elevated CRP. Compared to their US counterparts, pregnant Tsimane women exhibited elevated lymphocyte and eosinophil counts, fewer neutrophils and monocytes and lower CRP. Total leukocyte count remained high and unchanged among pregnant Tsimane women while pregnant US women exhibited substantially elevated counts, resulting in overlapping leukocyte prevalence among all third-trimester individuals. Conclusions and implications Our findings indicate that ecological conditions shape non-pregnant immune baselines and the magnitude of immunological shifts during pregnancy via developmental constraints and current trade-offs. Future research should investigate how such flexibility impacts maternal health and disease susceptibility, particularly the degree to which chronic pathogen exposure might dampen inflammatory response to fetal antigens. Lay Summary This study compares immunological changes associated with pregnancy between the Tsimane (an Amazonian subsistence population) and individuals in the USA. Results suggest that while pregnancy enhances non-specific defenses and dampens both antigen-specific immunity and parasite/allergy response, ecological conditions strongly influence immune baselines and the magnitude of shifts during gestation.

ABSTRACT Hematology has become important for making clinical diagnoses in snakes because maintenance techniques in captivity have been improving and increasing their life expectancy. The emergence of diseases in captivity requires the creation of parameters to understand the species in their healthy state. The possible association between the onset of neoplasia, immunosuppression, and viral infection are also important factors to consider. Thus, hematology is a fundamental tool for observing the responses of animals to diseases and treatments. The present study aims to study hematology between two species of snakes and compare the profiles observed with published results. Blood samples were collected from 16 male and female snakes: seven Corallus hortulanus from the family Boidae and nine Python bivittatus from the family Pythonidae belonging to the Biological Museum of the Butantan Institute, São Paulo, Brazil. Complete blood count results including blood smear, total erythrocyte count, leukocytes, and differential leukocyte count were evaluated. The data obtained in this study could help with the diagnosis, the treatment of snakes in captive conditions and in of nature conservation programs.

Evaluation of the effect of hydroalcoholic extracts of Cassia occidentalis leaves in neutrophil adhesion test in Rats. The effect of oral administration of hydroalcoholic extract of Cassia occidentalis leaves on neutrophil has been studied and is compared with control group on rats. The differential leukocyte count (DLC) was performed by fixing the blood smears and staining with leucofine and percent neutrophils in each sample was determined. After the initial counts, blood samples were incubated with 80 mg/ml of nylon fibers for 10 min at 37ºC. Supplementation with hydroalcoholic extract of Cassia occidentalis leaves significantly decreased neutrophil adhesion. The results indicate that the leaf of Cassia occidentalis is endowed with protected neutrophil adhesion. These effects could conclude that Cassia occidentalis has an antiasthmatic property.

Blood parameters are an important index to assess the body homeostasis in mammals. Here, the effect of pesticide (imidacloprid) contaminated feed exposure on the haematological parameters of adult rabbits (n=15) was studied. Pesticides (Imidacloprid, Bildor® 0.5ml (100mg)/L water spray on vegetables and green grass) exposed feed fed to rabbits with wash (washed feed rabbit) or without a wash (not washed feed rabbit) in the once-daily morning for every alternative day up to 15 days. Control rabbits have received a standard diet (fresh vegetables and green grass). The blood cell analysis showed that the total erythrocyte count, packed cell volume, and haemoglobin values were not changed significantly in pesticide exposed rabbit. For differential leukocyte count, the percentage of neutrophil and eosinophil was significantly decreased in the pesticide-exposed rabbit as compared to the control rabbit. The lymphocyte percentage was increased significantly in pesticide-exposed rabbits compared to control rabbits. Interestingly, the number of lymphocytes was significantly increased in not washed feed rabbits compared to wash feed rabbits. The results of the present study suggest that residue of agriculturally used pesticides may affect the body homeostasis of animals. Res. Agric., Livest. Fish.7(3): 439-444,  December 2020
