Hippocamelus antisensis (d'Orbigny 1834), commonly called taruca, is a deer that lives in Peru, Bolivia and Chile between 3500 to 5000 m, and is considered a vulnerable species. The axial skeleton of the taruca is described based on four specimens (two males and two females), according to authorization RDG N° 158-2015-SERFOR-DGGSPFFS. The bone pieces were obtained according to the anatomical technique, the description is in accordance with the Veterinary Anatomical List and the measurements as described by Von den Driesch. In the skull, the occipital does not have a very prominent occipital protrusion, the frontal bone is characterized by its horn process and by presenting up to three supraorbital foramina, the lacrimal has a deep fossa and a fissure covered by cartilage, the incisor bone and maxilla are elongated, in the maxilla there is the presence of a dental socket for the canine, ...

Diarrhea in alpacas is a clinically significant condition and the primary cause of morbidity in neonatal Peruvian alpacas. This study aimed to correlate early diarrhea in crias of alpaca with changes in the microbiota community. A total of 19 alpacas (aged 1–2 months) were collected, including nine with a health condition and ten healthy ones. Fecal samples were obtained under sterile conditions and their DNA was extracted. Sequencing of the V3-V4 region of the 16S rRNA gene was conducted in the Illumina platform, followed by bioinformatics analysis. Reduced microbial diversity was evident in alpacas afflicted with diarrhea, delineating contrasting microbial compositions in comparison to their healthy counterparts. The study characterized the predominant bacterial classes and phyla within the gut microbiota, with Firmicutes, Verrucomicrobiota, and Bacteroidota collectively constituting...

The aim of this study was to describe the arterial supply of the uterine-fetoplacental complex in alpacas during gestation. In total, 26 female alpacas were used; of these, 5 non-pregnant females were used to describe the irrigation of the reproductive tract and the origins of its irrigation; and 21 pregnant females were distributed in subgroups of 7 and slaughtered when they reached the 1st, 2nd and 3rd third of gestation, respectively. The specimens were processed using the filling-corrosion technique. Observation of uterine irrigation in pregnant and non-gravid uteri shows that it originates from the abdominal aorta artery, from where the ovarian arteries emerge, which pass towards the ovaries and from where they continue through the cranial uterine arteries and enter the uterine horns where they anastomose with the lateral and ventral branches of the caudal uterine arteries that take...

Alpacas, important genetic resources in the Andean region of Peru, are vulnerable to diarrhea caused by pathogenic parasites such as Eimeria lamae and Giardia sp., which can be fatal, especially in neonates, due to their physiological immaturity and limited adaptability. The study investigated the diversity and abundance of intestinal fungi and protists in alpacas infected with Eimeria lamae and Giardia sp. compared to healthy alpacas. A total of 19 alpacas, aged between one and two months, were included. They were divided into two groups, one with pathological conditions (nine) and the other healthy (ten). Parasitological analyses for the detection of parasites and subsequent molecular analysis were performed on the collected fecal samples. The results revealed a greater diversity and abundance of protists in infected alpacas in comparison with healthy alpacas, while the fungal composit...
