“…39,40 In addition, bearded capuchins (Sapajus libidinosus) also have been reported to have relatively low tear production (2.5 ± 2.94 mm/min), speculatively attributed to the use of detomidine in addition to ketamine in the anesthetic protocol. 41 Age was found to be unrelated to STT values in the only other prior NHP study that used age as a variable, 37 in contrast to our results which showed that JAGM had significantly lower tear production than AAGM or GAGM. However, the aforementioned study had a relatively small sample size of 15 primates from ages 6 to 20 years old, which excludes comparison to a juvenile group.…”

ObjectiveTo document ocular lesions and establish ophthalmic diagnostic test reference values in a colony of African green monkeys (Chlorocebus aethiops sabaeus).Animals StudiedFifty one geriatric (GAGM, 19–30 years old), 10 adult (AAGM, 5–9 years old) and 10 juvenile (JAGM, <2 years old) African green monkeys housed in a single Caribbean research colony.ProceduresOcular biomicroscopy, indirect fundoscopy, Schirmer tear test (STT), rebound tonometry (TonoVet®) and corneal fluorescein staining were performed. Mixed ANCOVA tests were performed to compare STT and IOP between groups.ResultsCommon ocular lesions in GAGM included vitreal degeneration (27/51, 51/102 eyes) and cataracts (21/51, 32/102 eyes). Vitreal degeneration was also common in AAGM (8/10, 16/20 eyes) and infrequent in JAGM (3/10, 6/20 eyes). Cataracts were not present in any JAGM or AAGM. All eyes in all three groups had perilimbal corneal pigmentation and faint lace‐like anterior corneal stromal opacification. Median (range) STT values were 16.0 (18) mm/min in GAGM. Mean (SD) STT values were 14.2 (4.6) mm/min in AAGM, and 8.9 (3.4) mm/min in JAGM. Median (range) IOP values were 16.5 (27) mmHg in GAGM. Mean (SD) IOP values were 18.0 (2.8) mmHg in AAGM, and 14.1 (2.2) mmHg in JAGM. JAGM had significantly lower STT and IOP values compared to AAGM (p = .0449, .0057, respectively) and GAGM (p = .0002, .0130, respectively).ConclusionsSpontaneous ocular lesions were common in geriatric monkeys in this research colony. IOP and STT values were lower in juvenile African green monkeys relative to adult or geriatric animals.

“…The IOP results from Guianan squirrel monkeys were lower than the IOP for the black-tufted marmosets and the night monkeys. Values for the two last species are more closely related to the IOP values reported for New World NHP including 18.4 ± 3.8 mmHg for Cebus apella 13 ; 19 ± 4 mmHg for Sapajus xanthosternos 16 ; 13 ± 3 mmHg for Sapajus libidinosus 2 , and 13 ± 1 mmHg for Aotus trivirgatus . 9,20 This relatively low value for Guianan squirrel monkeys requires more investigation to determine the reason for this difference.…”

“…The Cochet-Bonnet esthesiometer gauges the longest length of a nylon filament of 0.08 mm in diameter, causing nociception when in contact with the cornea. The CTT is inversely proportional to the magnitude of measurement in filament length (cm) and its pressure applied on the corneal surface (g/mm 2 ). On the day the data from Guianan squirrel monkeys and night monkeys were acquired at CENP, Ananindeua, Pará, Brazil, mean temperature was 32° and mean humidity 58%.…”

The goals of this study were to compare ocular morphology, determine the reference intervals of selected ophthalmic tests, ocular measurements, intraocular pressure, and tear production, and to establish possible relationships in the visual ecology of three different Neotropical nonhuman primates (NHP). Nineteen black-tufted marmosets (Callithrix penicillate), 24 Guianan squirrel monkeys (Saimiri sciureus), and 24 night monkeys (Aotus azarae infulatus) were included in the study. Schirmer tear test, ocular dimensions, ocular ultrasonography, intraocular pressure, central corneal thickness, and corneal touch threshold were determined. The ratio of the average corneal diameters and axial diameters (CD/AGL) were established. No significant difference was noted between males and females, nor left and right eyes, for all three species for all measurements (P > 0.05). CD/AGL ratio was significantly higher (P < 0.0001) in night monkeys (a nocturnal species) as compared to black-tufted marmoset and Guianan squirrel monkeys (two diurnal species). The reference intervals will aid veterinary ophthalmologists to more accurately diagnose pathological changes in the eyes of these species. In addition, ocular dimension comparison will allow other NHP species to be evaluated and examined in relationship to behavioral traits (nocturnal versus diurnal).

Background The aim of this work was to identify gram‐positive bacteria and their respective resistance profiles of free‐living capuchin monkeys. Methods For this, 15 Sapajus nigritus were captured in a municipal urban park in the northern region of the state of Paraná, Brazil, and under pharmacological restraint, samples were collected with sterile swabs from the oral, rectal, ocular, nasal, and auricular regions. After isolation of the 22 gram‐positive bacteria, each isolate was subjected to the catalase and coagulase tests for presumptive identification. Subsequently, phenotypic tests for bacterial resistance were performed using the agar diffusion disc method. The samples resistant to oxacillin were submitted to the PCR technique to search for the mecA gene. Results Of the 22 gram‐positive cocci of these two (9.09%) are Streptococcus spp. and twenty (90.91%) Staphylococcus spp. Among Staphylococcus spp. three (13.64%) were coagulate‐negative (CoNS) and seventeen (86.36%) coagulate‐positive (CoPS). Of the antimicrobials tested, enrofloxacin had the best performance, with only one (04.54%) isolate resistant to it, on the other hand, the antimicrobials with the lowest performance were cefotaxime and penicillin with 19 (82.36%) and 18 (81.81%) resistant isolates, respectively. Only five isolates had MAR less than 0.2, being one ocular, one oral, and three nasal, they had multiple resistance index varied between 0.07 and 0.92, with an average of 0.45 and a mode of 0.3. Among the samples with the highest resistance index, a positive coagulase Staphylococcus stood out, being intermediate to gentamicin and resistant to other antibiotics and an intermediate streptococcus to gentamicin, enrofloxacin, and resistant to other antibiotics. No sample was positive to mecA gene. Conclusions Future studies should be conducted to identify the Staphylococcus species, the high rate of antimicrobial resistance of the monkeys in this study suggests that Grooming's behavior may be contributing to the sharing of the resistant microorganism among the members of this group of primates.
