Safety And Efficacy

AbstractDue to the limited utility of Bacillus Calmette–Guérin (BCG), the only approved vaccine available for tuberculosis, there is a need to develop a more effective and safe vaccine. We evaluated the safety and efficacy of a dry powder aerosol (DPA) formulation of BCG encapsulated alginate particle (BEAP) and the conventional intradermal BCG immunization in infant rhesus macaques (Macaca mulatta). The infant macaques were immunized intratracheally with DPA of BEAP into the lungs. Animals were monitored for their growth, behaviour, any adverse and allergic response. The protective efficacy of BEAP was estimated by the ex-vivo H37Rv infection method. Post-immunization with BEAP, granulocytes count, weight gain, chest radiography, levels of liver secreted enzymes, cytokines associated with inflammation like TNF and IL-6 established that BEAP is non-toxic and it does not elicit an allergic response. The T cells isolated from BEAP immunized animals’ blood, upon stimulation with M.tb antigen, secreted high levels of IFN-γ, TNF, IL-6 and IL-2. The activated T cells from BEAP group, when co-cultured with M.tb infected macrophages, eliminated largest number of infected macrophages compared to the BCG and control group. This study suggests the safety and efficacy of BEAP in Non-human primate model.

The Relationship

Throughout the primate order, individuals are highly motivated to handle infants that are not their own. Given the differing and often conflicting interests of the various participants in handling interactions (handler, infant, and mother), most functional hypotheses are specific to particular handling roles. Here we explore one hypothesis that may apply to all participants, but that has received relatively little attention: that handling may facilitate the formation and maintenance of social bonds. Using free-ranging rhesus macaques (Macaca mulatta) on Cayo Santiago, we examine the relationship between infant handling in the early weeks and the strength and diversity of infant social bonds months later, when infant relationships were more independent from those of their mothers. Our results largely confirm the influence of several social characteristics (kinship, rank, sex, and age) in governing handling interactions. They also provide the first evidence that early handling is associated with later social bonds that are stronger than expected based on these social characteristics. However, the enhancement of bonds is largely confined to related handlers; frequent unrelated handlers did not generally go on to form strong bonds with infants. This suggests that kinship may be a sort of prerequisite to the enhancement of social bonds via handling. Given the adaptive benefits of strong social bonds among adult primates, future research should investigate whether early infant handling may have longer term fitness effects.

Recorded Data

In this article, we attempt to characterize the widespread trade in pet macaques in Vietnam. Data on confiscations as well as surrenders, releases, and individuals housed at rescue centers across Vietnam for 2015–2019 were opportunistically recorded. Data comparisons between Education for Nature Vietnam and three government-run wildlife rescue centers show that at least 1254 cases of macaque keeping occurred during the study period, including a minimum of 32 Assamese macaques (Macaca assamensis), 158 long-tailed macaques (Macaca fascicularis), 291 Northern pig-tailed macaques (Macaca leonina), 65 rhesus macaques (Macaca mulatta), and 110 stump-tailed macaques (Macaca arctoides). A minimum of 423 individuals were confiscated, and at least 490 individual macaques were released. Three semi-structured interviews were conducted with two key Animals Asia (a non-governmental organization) colleagues and their insights are presented. Although we recognize that the data included are limited and can serve only as a baseline for the scale of the macaque pet trade in Vietnam, we believe that they support our concern that the problem is significant and must be addressed. We stress the need for organizations and authorities to work together to better understand the issue. The keeping of macaques as pets is the cause of serious welfare and conservation issues in Vietnam.
