In June 2012, as a result of a marine phenomenon that resulted in the death of birds of several species of seabirds, endoparasites were studied in two pelicans (Pelecanus thagus) and two penguins (Spheniscus humboldti) found dead on the beach in the district of Chorrillos, Lima (Peru). The helminths were obtained from the digestive tract in both species using the Travassos protocols. The nematodes Contracaecum rudolphii and Syngamus trachea, the cestode Tetrabothrius sp, the trematode Galactosomum puffini and the acanthocephalan Corynosoma sp were identified in Pelecanus thagus. In Spheniscus humboldti, the trematode Cardiocephaloides physalis and the nematodes Contracaecum pelagicum and Cyathostoma phenisci were identified. Syngamus trachea, Galactosomum puffini, Corynosoma sp and Contracaecum pelagicum are considered new reports in Pelecanus thagus in Peru. In addition, Spheniscus humb...

The aim of this study was to identify and evaluate the antibiotic susceptibility of the main bacterial pathogens isolated from cases of cervical lymphadenitis in guinea pigs from two commercial-family breeding centres in the province of Canchis, Cusco. In total, 64 samples of cervical abscesses were processed between September 2018 and March 2019. The samples were cultured and the antibiogram on agar with discs of the main antibiotics used in family-commercial rearing systems was carried out. Beta-hemolytic Streptococcus sp (91.8%, 56/61), Staphylococcus sp (45.9%, 28/61) and Klebsiella sp (21.3%, 13/61) were identified. The highest frequency of isolates occurred in adult guinea pigs. The frequency of antimicrobial susceptibility was high for all the isolated genera, except for enrofloxacin and trimethoprim-sulfamethoxazole for beta-hemolytic Streptococcus sp. The results show a diversit...

The study aimed to describe the microbiota present in alpaca semen. Fifteen semen samples were collected using the artificial vagina, electroejaculation and post-copula techniques (five per technique). In addition, preputial (n=5) and vaginal (n=5) swabs were made. Microbiological cultures were made to determine the bacterial and fungal genera and an assessment of the bacterial load by determining the number of colony-forming units (CFU/ml). Six bacterial genera were identified in the vagina and seven in the prepuce, in addition to a fungal species (Aspergillus fumigatus). Bacteria of the genera Escherichia, Staphylococcus, Streptococcus and Bacillus were the most abundant and present in semen obtained by the three techniques, coinciding with those found in preputial and vaginal swabs. The amount of CFU/ml was similar for the three techniques, while there was no presence of fungi in the ...

The aim of this study was to determine some reproductive parameters (gestation rate, number of young, age distribution and reproductive age) of female vicuñas in two management systems: wild and captivity, in the Cusco Region, Peru. The capture of the animals ("Chaccus") were carried out between May and August 2017. The pregnancy was determined by transrectal ultrasound in 143 females, the presence of offspring by observing functional udder in the females, the age distribution and reproductive age by means of the records of capture and observation of the dentition. The percentage of gestation was of 74.6 and 79.4% for the wild and captivity systems, respectively. In the juvenile population were pregnant 29.9 and 4.4% in the wild and in captivity, respectively. The number of young animals in the wild was 36% and in captivity 53%. The proportion of young vicuñas was similar in both manag...

Two embryo production protocols were evaluated: superovulation and single ovulation, determining the collection rate and quality of the embryos, as well as fertility and natality during the reproductive and non-reproductive season, at 4200 meters above sea level and under field conditions. The collection rate of embryos in simple ovulation was 53% (44/83) embryos versus 242.3% (63/26) in superovulation. The quality of the embryos collected by single ovulation was: grade I (90.3 and 83.6%) and grade II (9.4 and 16.7%) and none of grade III; while in superovulation it was: grade I (76.6 and 87.5%), grade II (14.9 and 12.5%) and grade III (8.5 and 0%) for the reproductive and non-reproductive seasons, respectively. Fertility was similar between single ovulation (56.4%) and superovulation (56.0%). The birth rate was 41.1 and 30.0% for single ovulation and superovulation, respectively. It is ...

The vicuña is an emblematic species of fauna conservation in Peru. The vicuña population recovered after several years of timely measures for their conservation, moving to appendix II of CITES. Currently there are vicuñas that are kept free (silvestry) and populations kept enclosed in permanent fences (captivity). During 2018, 58 programmed captures (known as Chacus) were done in the Cusco Region, capturing 6777 animals, corresponding to 3229 and 3548 heads for silvestry and captivity, respectively. The age distribution in the case of juveniles was higher in silvestry (18.08%) with respect to the captivity system (7.2%), which would be evidence of the existence of higher mortality in this population. The 2012 national census indicated a higher proportion of female vicuñas in the general population of the Cusco Region; however, in this work similar populations were found by sex in bot...

This aim of this study was to describe the fibre diameter and fleece weight of vicuñas in the Cusco Region, Peru. The fibre diameter of 302 fibre samples of young, juveniles and adult vicuñas were evaluated using an OFDA 2000® equipment. The samples were collected in different programmed captures (called Chaccus) under two management systems: wildness and semi-captivity. In addition, 633 fleeces were weighed and differentiated by age, sex and type of management of the animals. The present study was authorized through the Resolution of General Direction N.° 180-2016-SERFOR/DGGSPFFS. The average fineness of the fibre of young (13.24 μm), juveniles (12.03 μm) and adults (12.72 μm) was determined. The fineness of fibre for males and females was 12.99 and 13.53 μm in young, 12.06 and 12.02 μm in juveniles and 12.88 and 12.58 μm in adults respectively. The smallest diameter of the fi...

Natural infection by Fasciola hepatica is recorded in a white-tailed deer (Odocoileus virginianus) and a taruca (Hippocamelus antisensis), both from the department of Cusco. Animals were remitted to the Veterinary Institute (IVITA-Maranganí, FMV, UNMSM) by the authorities of the National Service of Flora and Fauna (SERFOR, Cusco Headquarters). Six trematodes were collected from the bile ducts during the necropsy of the animals, and they were preserved in 70% ethanol. Morphological analysis indicated that they correspond to F. hepatica. This was confirmed by analyzing of the mitochondrial DNA of the parasites by partially amplifying the cytochrome c oxidase subunit 1 (cox1) and the NADH dehydrogenase subunit 1 (nad1) genes. Analysis of these genes had an identity greater than 99% compared to genes from GenBank. The present study demonstrates the occurrence of F. hepatica in these cervids...
