ABSTRACT
Helicobacter is a genus of Gram-negative bacteria that colonizes the stomach of humans and dogs, among other mammals. The most frequent species found in the gastric mucosa of man is H. pylori, however, there are other species of Helicobacter in the stomach of humans, such as H. suis, H. bizzozeronii, H. felis, H. salomonis and H. heilmannii sensu stricto, named non H. pylori Helicobacter (NHPH) some of which also colonize the dog's stomach. The detection of NHPH in the stomach mucosa of humans with gastric disease, and in a high percentage of dogs, suggests the possibility that these animals play an important role in the pathogenesis and transmission of infection to man, postulating the path of transmission oral-oral or fecal-oral. The aim of this study was to determine whether people with signs of chronic gastritis who have Helicobacter spp. and who own dogs as pets, share the same species with them. The presence of Helicobacter spp. in gastric samples of 30 people with clinical signs of chronic gastritis and histopathological diagnosis of gastric infection with Helicobacter spp. was analyzed by PCR. The presence of Helicobacter spp. was also studied in the dogs of these people. Then, the species of Helicobacter presented was determined in both. In human gastric samples, H. pylori was the only species found, while in dogs, samples were H. bizzozeronii, H. felis, H. salomonis and H. heilmannii. In this work the same species were not found in dogs and their owners.
Helicobacter es un género bacteriano gram negativo que coloniza el estómago de humanos y perros, entre otros mamíferos. En la mucosa gástrica del hombre la especie más frecuentemente hallada es H. pylori, sin embargo, puede albergar otras especies, como H. suis, H. bizzozeronii, H. felis, H. salomonis y H. heilmannii sensu stricto, denominadas Helicobacter no H. pylori (NHPH), algunas de las cuales colonizan también el estómago del perro. La detección de especies NHPH en la mucosa del estómago de seres humanos con enfermedad gástrica y en un alto porcentaje de perros como mascotas, sugiere la posibilidad de que estos animales jueguen un rol importante en la patogenia y transmisión de la infección al hombre, postulándose la vía de transmisión oral-oral o bien fecal-oral. El objetivo de este trabajo fue determinar si individuos con signos de gastritis crónica que tienen Helicobacter spp. y que poseen perros como mascotas, comparten con ellos las mismas especies. Para ello se estudió por PCR la presencia de Helicobacter spp. en muestras gástricas de 30 pacientes con signos clínicos de gastritis crónica y diagnóstico histopatológico de infección gástrica con Helicobacter spp. También se estudió la presencia de estas bacterias en sus perros para determinar si existe correspondencia en las especies presentes en ambos. La única especie encontrada en humanos fue H. pylori, mientras que en los perros se encontraron H. bizzozeronii, H. felis, H. salomonis y H. heilmannii. En este trabajo no se encontraron las mismas especies en los perros y en sus propietarios.

The Dogo Argentino (DA) is the first and only breed from Argentina recognized worldwide. Although its morphologic features have been well established, its normal reproductive parameters are not clearly known. The aim of this study was to determine the main DA bitch reproductive parameters. One hundred and forty-nine surveys were obtained from breeders from Córdoba province, Argentina: one for each intact DA bitch from 1 to 14 years old. The DA bitch reached puberty at an average of 8.93 months. The mean duration of vulval bleeding found in this study was 11.11 days. The clinical signs characteristic for proestrous-estrous were vulval edema (89.93%), bleeding during the time of mating (32.21%), holding the tail to the side (95.30%), and docility during mating (85.91%). DA bitches had a whelping rate of 84%. Out of 299 pregnancies, 89.30% exhibited a normal parturition, 6.69% presented dystocia, 2.68% needed Cesarean section, and 1.34% aborted. In conclusion, the reproductive parameters of the DA bitch are similar to those identified for other large breeds. DA often showed a prolonged vulval bleeding longer than proestrus. Its high whelping rate, its low incidence of dystocia, and its good maternal ability define the DA as a good reproductive breed with normal reproductive functions.
ABSTRACT
La colecistitis es una patología inflamatoria de la vesícula biliar (VB) y la obstrucción e infección biliarserían las causas principales de su presentación. El diagnóstico es difícil, porque tanto los signos clínicoscomo las anormalidades clínico-patológicas son poco específicas, por lo que la ecografía resulta unamodalidad diagnóstica importante, ya que la visualización ecográfica de espesamiento de la pared de laVB o de bilis hiperecogénica induce a la sospecha de colecistitis. El cultivo y antibiograma biliar permitendefinir el tratamiento antibiótico específico. Se describe un caso clínico donde se destaca la importancia dela ecografía en el diagnóstico de la colecistitis canina.
The cholecystitis is a gall-bladder inflamatory patology, the obstruction and biliar infection could be theprincipal causes of presentation. The diagnosis is dificult because the clinical signs as clinicopatologicalabnormalities are inespecifics, so the ultrasonography is a important method of diagnosis, because thevisualization of thickeny of the gall-bladders wall or hiperecogenic bile induce to suspect cholecystitis. Thebile culture and antibiograma permit to define the specific antibiotic treatment. A clinic case is described toemphasize the importance of ultrasonography in the canine cholecystitis diagnosis.
