    Detección de anticuerpos contra serovares de Leptospira interrogans en cuyes de crianza intensiva en Lima, Perú [Detection of antibodies against serovares of Leptospira interrogans in Guinea pigs of intensive breeding in Lima, Peru]
    (Veterinary Organization, 2017) Vexelman, D.F.; Morales, S.C.
    The aim of the study was to identify the presence of antibodies in Guinea pigs (Cavia porcellu) against serovars of L. Icterohaemorrhagiae, L. Bratislava, L. Pomona, L. Hardjo, and L. Canicola. A total of 155 samples were obtained from Guinea pigs in five different locations in Lima. The samples were taken to the laboratory of microbiology and they were centrifuged at 2500 rpm during 5 minutes with the goal to obtain the blood serum necessary to perform the micro agglutination test (MAT). 31.61% (49/155) of seropositive animals were identified, antibody titres of 1: 100 and 1: 200 were detected; with a frequency of 20.65% (32/155) against serovar L. Ichterohaemorragiae, 7.09% (11/155) against L. Pomona, 5.16% (8/155) against L. Canicola and 1.29% (2/155) against L. Hardjo. A significant statistical association (p <0.05) was found between the variables of test positivity versus sex and sampling site, using the Chi square test (X2). © 2017 Veterinary Organization.

    Identificación de agentes bacterianos aislados de gazapos muertos de cuyes en una granja de crianza intensiva en Lima, Perú [Identification of bacterial isolated from dead baby Guinea pig in an intensive breeding farm in Lima, Peru]
    (Veterinary Organization, 2017) Chuquizuta, C.R.; Morales, S.C.
    The aim of the study is to identify the bacterial agents present in dead baby Guinea pigs from an intensive breeding farm in the district of Manchay, Lima. 191 dead baby Guinea pigs were collected, which were identified and transported at 4 ° C. The processing of the samples was carried out in the Laboratory of Veterinary Microbiology of the Universidad Científica del Sur. The necropsy was performed, taking samples from the liver, intestine, spleen and lung; which were processed in Mc conkey, xylose lysine deoxycholate and blood agar, and the corresponding biochemical tests. The bacterial agents identifyied were E. coli (40.84%), Salmonella spp. (39.27%), among other; at organ level, 32.36% were isolated bacteria in liver, 28.46% in intestine, 20.65% in spleen and 18.54% in lung; showing a significant association (p<0.05) between the bacteriological diagnosis of Salmonella spp. and E. coli, against the evaluated organs. © 2017 Veterinary Organization.

    Resistencia antibiótica de patógenos bacterianos aislados de mastitis clínica en bovinos de crianza intensiva [Antibiotic resistance of bacterial pathogens isolated from clinical mastitis in intensive bovine breeding]
    (Veterinary Organization, 2017) Villanueva, G.T.; Morales, S.C.
    The objetive of the present study is to determine antibiotics' resistance developed by bacterial agents that produce bovine mastitis in intensive of four farming in Lurin. In this context, 139 samples were collected in sterile vials, keeping them at 4°C while taking them to the Microbiology Laboratory. Then, the samples were sown on agars Mc Conkey and blood, incubitating them at 37°C for 4 hours to proceed to the identification of bacteria, resulting in the presence of Staphylococcus aureus (24.84 ± 6.76)%, Streptococcus agalactiae (15.92 ± 5.72)%, Enterobacter aerogenes (6.37 ± 3.82)%, Enterobacter cloacae (3.82 ± 3.00)%, Bacillus sp (3.18 ± 2.75)%, Bacillus subtilis (3.18 ± 2.75)%, Citrobacter freundii (3.18 ± 2.75)%, and others. Staphylococcus aures strains were resistant to Penicillin 65.63%, while Streptococcus agalactiae were resistant to Cefalexin 56%, Penicillin 56% and Cefalotin 52%. The test was taken (p<0.05), being these antibiotics related to stable 3 to be statistically significant. © 2017 Veterinary Organization. All rights reserved.
