El presente estudio tuvo como objetivo determinar la seroprevalencia del virus herpes bovino tipo 1 (VHB-1), agente causal de la Rinotraqueítis Infecciosa Bovina (RIB); en bovinos de crianza extensiva sin historia de vacunación, en los distritos de San Pablo, Tumbaden y San Bernardino; de la provincia de San Pablo, Departamento de Cajamarca. Se determinó la presencia de anticuerpos a través de la prueba de neutralización viral en 480 muestras de suero sanguíneo bovino, recolectadas durante los meses de Octubre y Noviembre del 2004. Se encontró que el 0.62 ± 0.7% (3/480) de los bovinos muestreados presentaron anticuerpos neutralizantes, contra el VHB-1; dos bovinos con títulos de 1:64 y el otro con 1:32; todos ellos hembras, con edades mayores a los 6 años y que pertenecen a un solo lote de animales. Estos resultados contrastan con otros estudios realizados en otras partes del P...

The present study aimed to determine the antimicrobial susceptibility of Escherichia coli isolates in neonatal alpacas with and without diarrhea in peasant communities in Lachocc, Huancavelica, Peru. Rectal swabs from alpacas with diarrhoea (n=95) and from apparently normal alpacas (n=60) of 1 to 2 months of age were analysed. The results showed that 48.4% (46/95) and 60% (36/60) of samples from animals with and without diarrhea were positive to E. coli. The isolates were sensitive to most of the antibiotics, especially trimethoprim (98%), gentamicin (95%) and fosfomycin (88%). The exception was nitrofurantoin, whose strains showed low susceptibility (8.3%).

The fungus Histoplasma capsulatum is the causative agent of histoplasmosis, disease of public health importance. The aim of this study was to determine its presence in faeces of domestic pigeons (Columba livia) in the city of Lima, Peru. Faecal samples (n=245) were collected, processed and cultivated in Sabouraud agar at 37 and 28 °C for 2 to 4 weeks approximately. The colonies were identified by macroscopic and microscopic characteristics. Only 0.41% (1/245) of samples were positive to H. capsulatum, while the beta-pert (@Risk) stochastic simulation showed a minimum prevalence of 0.369% and a maximum prevalence of 0.451%.

The aim of this study was to determine the prevalence of antibodies against Chlamydophila abortus in cattle from the districts of Coracora, Chumpi and Pullo of the province of Parinacochas, department of Ayacucho, Peru. The animals were raised extensively and under natural breeding. In total, 184 blood samples were taken from cattle over 4 months of age regardless of sex. The detection of antibodies against C. abortus was done with a commercial indirect ELISA kit. A corrected prevalence of 40.34 ± 7.06% was obtained with a significant difference between districts (p<0.05), being lower in Coracora (40.29 ± 8.89%) and higher in Pullo (56.05 ± 7.15%), and without significant differences due to the effect of sex. breed, animal category and reproductive status. The high prevalence confirms the spread of the pathogen in the bovine population of the evaluated districts.

El 48.4% (46/95) y el 60% (36/60) de las muestras de animales con y sin diarrea fueron positivas al cultivo de E. coli.

La excepción fue la nitrofurantoína, cuyas cepas mostraron una baja susceptibilidad (8.3%).

The aim of this retrospective study was to describe the results of bacterial isolates and to determine the risk factors involved in the presentation of bacteriuria in cats with lower urinary tract disease (FLUTD). Clinical records of feline patients (n=102) who underwent urinalysis and urine culture were collected. The following variables were considered: age, sex, reproductive status, breed, bodyweight, season, colour of urine, urine odour, urine density, pH, glucose, proteins, blood, leukocytes, erythrocytes, crystals and type of crystals. In 60.8% (62/102) of the samples, bacteria were isolated in urine, including E. coli 40.3% (25/62), Klebsiella sp 12.9% (8/62), Staphylococcus sp 12.9% (8 / 62), Proteus sp 8.1% (5/62), Enterobacter sp 8.1% (5/62) and Staphylococcus epidermidis 6.4% (4/62). Age, urinary density and presence of blood were statistically significant. In addition, it was...
