Full text-- The process of sperm cryopreservation is widely used in the programs of assisted reproduction and genetic improvement of many species. The alpaca is a domestic species of economic importance in our country. There are many techniques for managing this species in order to carry out a genetic improvement program. For the cryopreservation of sperm, samples of sperm from semen and epididymis have been used, being more feasible for the present study the use of sperm from the epididymis. One feature present in the cryopreserved sperm in most species is a disturbance at the plasma membrane which leads to a premature acrosome reaction, as well as declining mobility, making the lifetime of the sperm very small. All these changes are the result of a special type of process called "Cryocapacitation" that so far, the possible cause, has not been defined. The aim of this study was to demonstrate the presence of a state of cryocapacitation on Alapaca’s cryopreserved spermatozoa, studying mainly mobility, viability and stability of the plasma membrane, the pattern of proteins phosphorylated in tyrosine residues, the state of Proacrosin-Acrosin system and the ability of binding to pellucida zone that have these cryopreserved sperm and compare these results with those from capacitated in vitro sperm. The results indicate that cryopreservation directly affects mobility, viability and integrity of acrosomal membrane, showing that both capacitated in vitro and cryopreserved sperm offered the same pattern of proteins phosphorylated in tyrosine residues and that cryopreserved sperm has an increment of active enzyme (Acrosin) in the acrosome region.

Full textSe evalúa la hipótesis que camélidos sudamericanos (CS) introducidos en la Región Metropolitana de Chile estén infectados con pestivirus. Para realizar el aislamiento viral se tomaron muestras de 79 CS (42 alpacas vivas, 30 llamas vivas, una llama muerta, un feto de llama abortado, cuatro guanacos vivos y un guanaco muerto) procedentes de cinco rebaños sospechosos de estar infectados con pestivirus. Las muestras se inocularon en cultivos primarios de células de pulmón fetal bovino libre de virus diarrea viral bovina (VDVB) y se hicieron cinco pasajes antes de ser analizados por las pruebas de inmunofluorescencia directa e inmunoperoxidasa indirecta para detectar la presencia de antígenos de pestivirus. Para la caracterización molecular un fragmento de la región no traducida 5’ (5’- UTR) del ARN de cada aislado fue amplificado por transcripción reversa de reacción en cadena de las polimerasas (RT-PCR) y tratado con las enzimas de restricción Pst I, Bgl I y Xho I para identificar la especie de los virus Los resultados muestran que 37 CS (17 alpacas, 16 llamas y cuatro guanacos de los cinco rebaños) estaban infectados con pestivirus. Todos los aislados fueron no citopatogénicos. El VDVB genotipo 1 (VDVB-1) fue aislado de 6 alpacas y VDVB genotipo 2 (VDVB-2) fue aislado de 11 alpacas, 16 llamas y 4 guanacos. Los aislados virales fueron obtenidos de 14 alpacas sanas, 3 alpacas que abortaron, 13 llamas sanas, dos llamas con aborto, una llama muerta sin antecedentes clínicos y tres guanacos con enfermedad respiratoria y uno muerto con enfermedad respiratoria. Se concluye que alpacas, llamas y guanacos de la Región Metropolitana de Chile están infectados con VDVB-1 y VDVB-2

Full text--- In areas of high-Andean Peru, where agriculture and livestock are not viable, the breeding of camels, such as alpaca is the only means of livelihood and main economic activity of farm households. Therefore, the study of the reproductive physiology of alpacas is essential to the establishment of projects in assisted reproduction and genetic improvement. The proteins involved in the interaction of the alpaca’s gametes are unknown; therefore the present determined the protein expression and characterization of a zona pellucida (ZP), which induce the spontaneous acrosome reaction (AR) in oocytes of alpacas. In most mammals, the zona pellucida (ZP) is composed by three glycoproteins ZP1, ZP2 and ZP3. In this research demonstrated that in Alpacas there are also 3 glycoproteins with molecular weights of 110 kDa, 75 kDa and 65 kDa corresponding to aZP1, aZP2 and aZP3, respectively. ZP3 is the natural agonist of the acrosome reaction (AR) in spermatozoa of the same species, however, our results obtained in this research showed that aZP3 can also induce RA in mouse sperm and in their own species. Therefore, this study helps to better understand the nature of the zona pellucida glycoproteins in alpacas.

Full textTen microsatellites for alpacas and llamas were used to evaluate paternity in 47 alpacas registered at IVITA Research Station Maranganí, Canchis Province (Cusco – Perú). Analysis was carried out using both methodologies: Automatic Sequencer (ABI 377 DNA sequencersâ) and silver staining techniques. Microsatellites were amplified in three multiplex reactions and ten single PCR reactions. They were polymorphic for all alpaca samples using both methodologies. The number of alleles varied between 4 and 20, the allelic frequencies and the exclusion probability were calculated using Cervus 2.0. All loci, except for two, were within the range published by Lang et al. (1996) and Penedo et al. (1998). The accumulated exclusion probability for the ten loci was 0.9999. For each multiplex reaction the accumulated exclusion probability was more than 0.90. Both methodologies yielded the same results. It was possible obtain the same results using both methodologies. The results confirmed paternity in 17 cases of parent-offspring pairs, however in a further 22% of cases alternative adults were identified as parents compared with the register.

Full text-- The Random Amplified Polymorphic DNA (RAPD) is applied on the molecular study of Lama pacos (Alpaca), this methodology is proposed because the microsatellites and DNA mitochondrial techniques, which are used commonly, don't have a practical utility when is necessary to analyze great quantity of samples. Genomic DNA obtained from total blood and primers of 10 nucleotides were used to standardize the RAPD technique following the standardized protocols, and concentration of MgCl2 was modified at 2.5 mM which allowed an increase at the intensity and a better visualization of the bands. After the standardization, the identification of informative primers was realized, beginning with 23 primers, selecting only 7 (OPF 05, OPI 04, OPB 03, OPI 18, OPB 11, OPA 18 and OPI 14), because the presence of several bands for the analyzed samples. These primers let obtain different profiles between hybrid and pure alapacas; in the sample were not found alpacas with a similar bands profiles to those presented by the pure animals, this would explain the hybridization grade that exists due to an inadequate care in the crossing, this results in, for example a low quality in the fiber production from the hybrid alpacas and llamas, diminishing the economic entrance for the rural families. In 8 alpacas the primers OPB-03 and OPA-18 showed polymorphic bands of 650 pb and 1000 pb respectively, this polymorphism could indicate some mutation or intraespecific variability, since these animals don't present evident phenotypic differences.

Full text--- Toxoplasma gondii, causative agent of toxoplasmosis, is an important parasite in animal health because it is one of the major parasitic infections that produce reproductive problems, and also it is an important zoonosis worldwide. The objective of this study was to determine the seroprevalence of antibodies against Toxoplasma gondii in alpacas from the Unit of Production of Cochas of the SAIS Tupac Amaru, located in the district of Canchayllo, Province of Jauja, Departament of Junin, Perú. To this end, sera from 200 alpacas among females and male were gathered in the month of December of 2000, for the detection of antibodies by using the method of Indirect Hemaglutination (IHA). 21 5.64 % (42/200) of the samples showed antibodies, with titles ranging from 1/16 up to 1/1024. The seroprevalence found in males was 26.47 (10.47% (18/64), and it was greater than in females, 18.18 6.57 % (24/132), and for age groups, from the birth until 1 year old, more than 1 up to 2 years old and more than 3 years old; the seroprevalence found was 33.33 16.08%, 15.38 9.8, 20 7.31 respectively. The analysis by using The Logistic regression found that the genus did not represent a risk factor. The age did represent a risk factor, being younger alpacas (8 to 12 months) more susceptible than other age groups. These results are coherent with other studies obtained in different parts of world, however, it is observed that there are differences with recent studies obtained in Peru; this, this could be due to environmental factors, frequency of the definitive host. Prevalence found in the present study was moderate, should be done further studies to determine the real importance of T. gondii in the occurrence of abortion in alpacas.

Full textThe zona pellucida is a extracellular matriz that surrounds vertebrate oocytes, and plays important roles in the recognition and interaction of gametes specie- specific, induction of Acrosome Reaction (AR) of the spermatozoa, block to polyspermy, keeps th integrity of the early embryo through its transicion by the oviduct; It is composed of three glycoproteins: ZP3 that induces RA; ZP1, structural, crosslink ZP3 and ZP2. ZP2 acts as a secondary sperm receptor that is necessary for the maintenance of sperm binding to the egg, its proteolytical modification after fertilization permits the block to polyspermy ZP2 participates also in the organization, development, maturation of the oocyte beacuse it keeps consistently the matrix and the interaction between peripherical cells with the germ cell. We isolated and analized in silico a partial coding secquence of the glycoprotein of type 2 (aZP2) in alpacas, we determined that this protein is express exclusively in the ovaries. Also this amalized partial secquence is conserved, constituting a monophyletic group between Cetarteodactyla. This thesis work provides basic knowledge on the glycoprotein a ZP2 in alpacas, a protein implicitly involved in fertilization, to know it benefits the improvement of existing reproductive biotechnology techniques such as the follicular-oocyte maturation, cryopreservation of gametes and embryos in vitro fertilization and injection of intracytoplasmic sperm, techniques that are trying to be implemented with many difficulties in camelids.

Full textEl virus de la diarrea viral bovina (VDVB) pertenece al género Pestivirus de la familia Flaviviridae. Se encuentra ampliamente distribuido en la naturaleza infectando a animales silvestres y domésticos del orden Artiodactyla. Es el agente causal del complejo diarrea viral bovina/enfermedad de las mucosas, ocasiona enfermedad digestiva y respiratoria, es inmunosupresor y genera importantes pérdidas económicas asociadas a problemas reproductivos como pérdida embrionaria, abortos, mortinatos, defectos congénitos y el nacimiento de animales persistentemente infectados (PI). Presenta una gran variabilidad genómica; dos genotipos (VDVB-1 y VDVB-2), y varios subgrupos genómicos dentro de cada genotipo, han sido identificados. Existen dos biotipos, citopático (CP) y no citopático (NCP), y aunque no presentan serotipos, existen varias variantes antigénicas del virus. En esta memoria se buscó establecer si se manifiestan diferencias significativas a nivel antigénico entre cepas de referencia (NADL, Singer y Oregon) del subgrupo 1a del VDVB-1 y aislados virales de diferentes genotipos y subgrupos del VDVB (VDVB-1b, VDVB-1e y VDVB-2a) recolectados de 3 bovinos, 6 alpacas y 5 llamas de la Zona Central de Chile, y que provenían de rebaños sanos y de rebaños con antecedentes de signos clínicos atribuibles a la enfermedad (abortos, mortinatos, y muerte en adultos). Los aislados de alpacas y llamas corresponden a virus de los subgrupos 1b y 1e del genotipo 1 del VDVB (VDVB-1b y VDVB-1e), y al subgrupo 2a del genotipo 2 (VDVB-2a); mientras que los aislados de bovinos pertenecen a los subgrupos VDVB-1b y VDVB-1e. Para determinar el grado de similitud antigénica entre los aislados y cepas de los distintos subgrupos se realizaron pruebas de neutralización cruzada, empleando antisueros policlonales (elaborados en conejos). Mediante el cálculo del coeficiente de similitud antigénica (R) se pudo detectar la presencia de diferencias antigénicas significativas entre aislados de subgrupos distintos, mientras que los ubicados dentro de un mismo subgrupo mostraron valores de R indicativos de similitud antigénica en casi todos los casos, excepto en la combinación de un virus de alpaca y uno de bovino, ambos del subgrupo 1b, que mostraron diferencias antigénicas significativas
