Studies Of Distribution And Recurrence Of Helicobacter Spp. Gastric Mucosa Of Dogs After Triple Therapy [estudos Da Distribuição E Recorrência Do Helicobacter Spp. Na Mucosa Gástrica De Cães Após Terapia Tríplice]

Purpose: To analyze the triple antimicrobial therapy in positive Helicobacter spp. dogs and to investigate recurrence. Methods: A total of 20 dogs underwent endoscopy followed by gastric biopsy using the rapid urease test and histopathology stained with Giemsa. Ten animals were treated with triple therapy recommended for humans and divided into control and experimental group. The control group was kept in isolation while the experimental group was placed in contact with positive animals during 60 days. Results: The prevalence of infection in animals in this experiment was 100%, and more frequent in the fundus and the gastric body. Therapy for 7 days using clarithromycin, amoxicillin and lansoprazole was effective in 100% of the animals. Recurrence of the infection in 80% of dogs in the experimental group, while the control group remained eradicated after 60 days. Conclusion: Crowded environments associated with close contact with dogs infected with helicobacter are a determinant for transmission of Helicobacter spp. between canines.2628287Ladeira, M.S.P., Salvador, D.M.F., Rodrigues, M.A.M., Biopatologia do Helicobacter pylori (2003) J Bras Patol Med Lab, 39 (4), pp. 335-342Marshall, B.J., Warren, J.R., Unidentified curved bacilli in the stomach of patients with gastritis and peptic ulceration (1984) Lancet, 1, pp. 1311-1315Carvalho, G.D., Pinto, P.S.A., Vilória, M.I.V., Nero, L.A., Aspectos zoonóticos de Helicobacter spp (2008) Biosci J, 24 (4), pp. 121-130Escobar, M.L., Kawakami, E., Evidence of mother child transmission of Helicobacter pylori infection (2004) Arq Gastroenterol, 41 (4), pp. 239-244Parente, J.M.L., Silva, B.B., Palha-Dias, M.P.S., Zaterca, S., Nishimura, N.F., Zeitune, J.M.R., Helicobacter pylori infection in children of low and high socioeconomic status in northeastern Brazil (2006) Am Soc Trop Med Hyg, 75 (3), pp. 509-512Strauss-Ayali, D., Simpson, K.W., Gastric Helicobacter infeccion in dogs (1999) Vet Clin N Am Small Anim Pract, 29 (2), pp. 397-414Neiger, R., Simpson, K.W., Helicobacter infection in dogs and cats: Facts and fiction (2000) J Vet Intern Med, 14 (2), pp. 125-133Happonen, E.U., Saari, S., Castren, L., Tyni, O., Hänninen, M.L., Westermarck, E., Comparison of diagnostic methods for detecting gastric Helicobacter like organisms in dogs and cats (1996) J Comparat Pathol, 115 (2), pp. 117-127Mendall, M.A., Northfeld, T.C., Transmission of Helicobacter pylori infection (1995) Gut, 37, pp. 1-3Fox, J.G., Non-human reservoirs of Helicobacter pylori (1995) Aliment Pharmacol Ther, 9 (2), pp. 93-103Coelho, L.G.V., Mattos, A.A., Francisconi, C.F.M., Castro, L.P., Suraia, A.B., Effcacy of the dosing regimen of pantoprazole 40 mg, amoxicillin 1000 mg and clarithromycin 500 mg, twice daily of 7 days, in the eradication of Helicobacter pylori in patients with peptic ulcer (2004) Arq Gastroenterol, 41 (1), pp. 71-76Coelho, L.G.V., Zaterca, S., Second Brazilian Consensus Conference on Helicobacter pylori infection (2005) Arq Gastroenterol, 42 (2), pp. 128-132Chether, L., Rodrigues, L., Faria, C.M., Recorrência da infecção por H. pylori na Unifesp (2005) GED, 24 (3), pp. 121-130Mesquita, M.A., Lorena, S.L., Zeitune, J.M.R., Montes, C.G., Guerrazzi, F., Carvalho, A.F., Santos, J.O.M., Almeida, J.R.S., Recurrence of Helicobacter pylori infection after eradication therapy in brazilian patients with peptic ulcer (2005) J Clin Gastroenterol, 39 (5), p. 447Moutinho, F.Q., Thomassian, A., Watanabe, M.J., Suzano, S.M.C., Sequeira, J.L., Prevalence of helicobacters and alterations in gastric mucosa of healthy dogs (2007) Arq Bras Med Vet Zootec, 59 (4), pp. 1080-1083Eaton, K.A., Dewhirst, F.E., Paster, B.J., Tzellas, N., Coleman, B.E., Paola, J., Sherding, N., Prevalence and varieties of Helicobacter species in dogs from random sources and pet dogs: Animal and public health implications (1996) J Clin Microbiol, 34, pp. 3165-3170Hänninen, M.L., Happonen, I., Saari, S., Jalava, K., Culture and characteristic of Helicobacter bizzozeronii, a new gastric canine Helicobacter sp (1996) Int J Syst Bacteriol, 46 (1), pp. 160-166Lee, A., Hazell, S.L., O'Rourke, J.L., Kouprach, S., Isolation of a spiral shaped bacterium from the cat stomach (1988) Infect Immunol, 56 (11), pp. 2843-2850Paster, B.L., Lee, A., Fox, J.G., Dewhirst, F.E., Tordoff, L.A., Fraser, G.J., O'Rouke, J.L., Ferrero, R., Phylogeny of Helicobacter felis sp. nov., Helicobacter mustelae, and related bacteria (1991) Int J Syst Bacteriol, 41, pp. 31-38Javala, K., Kaartinen, M., Utriainen, M., Happonen, I., Hänninen, M.L., Helicobacter salomonis sp. nov., a canine gastric Helicobacter sp.
