“…This serotype, however, when inoculated in chicks, did not maintain this level of pathogenicity. Sousa et al (2013) obtained similar results after orally inoculating chicks with 1.2 x10 8 CFU/ mL of Salmonella isolated from pigs raised near aviaries. These researchers did not register any deaths in the 21-day experimental period.…”

“…Previous studies also showed a greater percentage of positive results in the intestine relative to the liver and spleen (SOUSA et al, 2013). These authors showed that, at 15 dpi, ST was present in all cecum samples (n=63), but only 25% of birds had ST in the liver and spleen.…”

“…Sousa et al (2013), using ST isolated from pigs orally inoculated in chicks, observed that 100% of cloacal swabs were positive at 1 and 8 dpi. These authors used a concentration of 1.2 x 10 8 CFU/ mL, which may explain the elevated number of positive samples.…”

Several cases of animal and human salmonellosis caused by the Salmonella serotype Typhimurium have been reported. In animals, subclinical infection favors pathogen dissemination through feces. In this context, the domestic pigeon (Columba livia) with an asymptomatic condition may play an important role in the transmission of salmonellosis, through the elimination of contaminated feces in commercial aviaries or in poultry feed facilities, causing economic losses to the poultry industry and presenting a risk to public health. This study aimed to evaluate the mortality, clinical signs and the presence of Salmonella Typhimurium in the feces and organs of chicks previously inoculated with bacteria isolated from a pigeon. One-day-old chicks were distributed in two experimental groups (G1 and G2) of 32 birds each, and a control group of six birds. Two inocula of 0.4 and 0.7 mL with 10 5 and 10 6 colony forming units were used in G1 and G2 birds, respectively. At 1, 4, 7 and 14 days post-inoculation (dpi) fecal samples were pooled from each cage and individual cloacal swabs were collected. At 14 dpi, all chicks were euthanized and samples were collected from the liver, spleen, lung, cecum and intestine for microbiological analysis. Mortality was only observed among G2 birds (6.25%). Most birds presented clinical signs of diarrhea at 4 dpi and no symptom as observed at 14 dpi. The results from cloacal swabs demonstrated bacterial elimination in 68.8% and 53.1% of G2 and G1 birds, respectively at 1 dpi. Additionally, fecal samples had elevated bacterial shedding in all four periods of observation , with a higher excretion at 4 dpi (62.5%) for both groups. Among G2 birds, 74.2% were positive for the pathogen in the intestine; G1 birds presented the lowest rate of lung infection (29%), and both groups had more than 50% positivity for liver and caeca. The results revealed that infected chicks with a Salmonella Typhimurium strains isolated from pigeons may host the pathogen in several organs, and simultaneously present diarrheic disorders with significant levels of bacterial excretion in feces. ResumoNa literatura são relatados diversos casos de salmonelose em animais e humanos em vários países ocasionados pelo sorotipo Typhimurium. Em animais, a infeção subclínica favorece a disseminação do patógeno através das fezes. Nesse contexto, o pombo (Columba livia) com quadro assintomático pode desempenhar um importante papel na transmissão de salmonelose, mediante a excreção de fezes contaminadas em aviários comerciais ou em instalações de ração animal causando perdas econômicas para a indústria avícola, e proporcionando risco para a saúde pública. Objetivou-se avaliar a taxa de mortalidade, sinal clínico e a presença de Salmonella Typhimurium nas fezes e nos órgãos de pintinhos previamente inoculados com bactérias oriundas de pombo. Foram utilizados 70 pintos de corte de um dia de idade, os quais foram distribuídos aleatoriamente em dois grupos (G1 e G2) de 32 aves cada. Utilizou-se um grupo controle, constituído por seis...

“…The epidemiology of salmonellosis is complex. The high density in the poultry houses along with the persistence of the microorganism in water, feed ingredients, litter, and fomites as well as in biological vectors on the farm environment facilitate its dissemination [ 57 ]. Transmission occurs through horizontal and vertical routes in the case of pullorum disease and avian paratyphoid [ 55 , 58 ], and only by horizontal route in fowl typhoid [ 59 ].…”

Birds, including canaries and other birds, have become increasingly popular as pets. Bird fairs, where breeders gather and show their production in a championship setting, present a setting for possible Salmonella spp. contamination and transmission. Therefore, this study estimated the rate of Salmonella spp. isolation from cage papers, located in the bottom of cages of exotic pet birds, including canaries. Collected Salmonella isolates were used to determine the antimicrobial resistance profile to 52 antibiotics and 17 commercial disinfectants, based on pure or a mixture of acids, alcohols, aldehydes, alkalis, halogens, peroxygen, and quaternary ammonium compounds. The samples consisted of 774 cage papers taken in the 2015 Argentinean canary breeder championship, pooling three cage papers into one sterile sampling bag. Only one pool of the cage papers was positive for Salmonella spp. (0.4%), which belonged to the sample from three frill canary cages. Two strains of Salmonella serotype Glostrup were isolated, which were only resistant to sulfonamides and erythromycin and sensitive to alkali-based product PL301 AS. Although the rate of Salmonella spp. isolation from cage papers in an Argentinean canary breeder championship is low, it should not be discounted because Salmonella ser. Glostrup can be a source of human Salmonella outbreaks and they show high resistance to disinfecting products.
