The aim of the present study was to investigate the use of exogenous progesterone and equine chorionic gonadotrophin (eCG) in non-ovulated and ovulated, asynchronous dromedary camel recipients being prepared for an embryo transfer programme. The uteri of 12 mated donor camels were flushed non-surgically 7 days after ovulation and 42 embryos were recovered. In Experiment 1, 16 embryos were transferred non-surgically to recipients on Day 3 or 4 after ovulation (ov+3 and ov+4, respectively). Each recipient received a daily dose of 75 mg, i.m., progesterone-in-oil from 2 days before embryo transfer until 6 days after ovulation. Thereafter, the progesterone dose was reduced to 50 mg on Day 7 and finally to 25 mg day–1 on Days 8 and 9. Nine of 16 recipients (56%; ov+3, n = 4; ov+4, n = 5) became pregnant compared with none of eight non-progesterone treated controls, into which embryos were transferred on Day 4 after ovulation. In Experiment 2, 18 non-ovulated recipients received 75 mg, i.m., progesterone-in-oil daily from 3 days before until 12 days after non-surgical transfer of a Day 7 blastocyst, at which time pregnancy was diagnosed by ultrasonography. All pregnant recipients continued to receive 75 mg progesterone-in-oil daily for a further 6 days, when each camel received 2000 IU, i.m., eCG. Progesterone treatment was then reduced to 50 mg day–1 and, when a follicle(s) ≥1.3 cm in diameter were present in the ovaries, each animal received 20 μg buserelin to induce ovulation. Once the corpora lutea had developed, progesterone treatment was reduced to 25 mg day–1 for a final 3 days. Fourteen of 18 recipients (78%) became pregnant and seven of these (50%) remained pregnant after eCG treatment. Of the seven pregnancies that were lost, two were lost before eCG treatment, two did not respond to eCG treatment and three responded to eCG treatment and ovulated, but lost their pregnancies 6–8 days after the last progesterone injection.

Saguinus niger popularly known as Sauim, is a Brazilian North primate. Sympathetic chain investigation would support traumatic and/or cancer diagnosis which are little described in wild animals. The aim of this study was to describe the morphology and distribution of sympathetic chain in order to supply knowledge for neurocomparative research. Three female young animals that came death by natural causes were investigated. Animals were fixed in formaldehyde 10% and dissected along the sympathetic chain in neck, thorax and abdomen. Cranial cervical ganglion was located at the level of carotid bifurcation, related to carotid internal artery. In neck basis the vagosympathetic trunk divides into the sympathetic trunk and the parasympathetic vagal nerve. Sympathetic trunk ran in dorsal position and originated the stellate ganglia, formed by the fusion of caudal cervical and first thoracic ganglia. Vagal trunk laid ventrally to heart and formed the cardiac plexus. In abdomen, on the right side, were found the celiac ganglion and cranial mesenteric ganglion; in the left side these ganglia were fusioned into the celiac-mesenteric ganglion displaced closely to the celiac artery. In both sides, the caudal mesenteric ganglion was located near to the caudal mesenteric artery.

Equine dysautonomia (grass sickness) is characterized by autonomic neuronal degeneration and is often fatal. As outbreaks occur, rapid diagnosis is essential but confirmation currently requires histological examination. This study evaluated diagnostic accuracy of cytological examination of cranial cervical ganglion (CCG) scrapings for dysautonomia diagnosis. CCG smears from 20 controls and 16 dysautonomia cases were stained with May-Grünwald Giemsa (MGG), hematoxylin and eosin (HE), and cresyl fast violet (CFV), with HE-stained histological sections of CCG as gold standard for diagnosis. Examining all 3 stains together, the sensitivity and specificity were 100%. Occasional individual smears (4/107, 3.7%) were nondiagnostic due to low cellularity, and in a few individual smears the final diagnosis was correct but more tentative (CFV: 5/33 [15.1%], HE: 2/34 [5.9%], and MGG: 4/36 [11.1%]), due to low cellularity or suboptimal cell morphology. CCG cytology was considered reliable for rapid postmortem diagnosis of equine dysautonomia, particularly using MGG.
