Characterization of Salmonella isolated from pigs was conducted between January to November, 2008 in the district of Mymensingh. Out of 23 pigs examined, only 4 (17.39) pigs had Salmonella infection. Genome analysis using PCR revealed that ST gene of enterotoxin was absent in some strains of pigs Salmonella but it's not clear whether the serovars belongs to Salmonella (S.) choleraesuis, S. typhimurium or S. derby. The isolates were found to be highly sensitive to ciprofloxacin, kanamycin, nalidixic acid, co-trimoxazole and cephalexin but highly resistant to chloramphenicol.

“…The isolated Salmonella serovars produced opaque, translucent, colorless and smooth, round colonies on SS agar; pale colorless smooth, transparent, raised colonies on MC agar, pale pink color colonies in BG agar (Buxton and Fraser, 1977;Merchant andPacker, 1967 &Shaffer et al, 1964). In Gram staining, the isolated Salmonellae showed Gram negative, small rod shaped, single or paired in arrangement which was supported by other researchers (Gene, 2002, Jones et al, 1997and Freeman, 1985.…”

Isolation and Characterization of Salmonella Serovars from Buffaloes in Mymensingh, Bangladesh

et al. 2013

An investigation was carried out focusing the isolation and characterization of Salmonella serovars from buffaloes of some selected areas of Mymensingh district of Bangladesh. The objectives was to isolate and identify Salmonella serovars from diarrheic and apparently healthy buffaloes and to characterize the isolates by cultural and biochemical characteristics, serological tests and antibiotic sensitivity analysis. A total of 38 samples comprising rectal swabs and faeces were collected from 38 buffaloes originating from 3 selected areas of Mymensingh. Out of these 38 samples, 8 (20.63%) were found to be positive for Salmonella spp. All isolates fermented dextrose, maltose and mannitol with production of acid and gas but did not ferment sucrose and lactose. On the other hand, these isolates showed Indole and Voges- Proskaure test negative, Methyl-Red test positive. All these isolates subjected to rapid plate agglutination test with polyvalent “O” ( poly ‛O’) and polyvalent “H” ( poly ‛H’) antisera where positive agglutination were observed. All isolates were highly sensitive to ciprofloxacin, moderately sensitive to co-trimoxazole, gentamycin, tetracycline and less sensitive to erythromycin and resistant to furazolidone

“…In addition to these findings, an apparent gastritis was observed in the newly hatched chicks. Although C. jejuni is susceptible to killing by acid (Blaser et al, 1980), the gizzard mucosa of the newly hatched chick has a higherpH (5-1-6-2) before exposure to food and water than it does afterwards (3-3-4.5) (Shaffer et al, 1964). The chicks in our study were given C. jejuni before feeding.…”

“…Young birds lack a fully developed flora, which may play a protective role against enteric pathogens (Abrams and Bishop, 1966;Turnbull and Richmond, 1978;Berg and Garlington, 1979). Also, the immunological, anatomical and physiological immaturity of the intestinal tract and reticuloendothelial system of newly hatched chicks may contribute to increased susceptibility to infection (Shaffer et al, 1964;Abrams and Bishop, 1966;Fuller and Jayne-Williams, 1970;Lawrence et al, 1981).…”

Experimental Gastroenteritis in Newly-Hatched Chicks Infected with Campylobacter Jejuni

SUMMARY. The susceptibility of chicks to enteritis caused by Campylobacter jejuni was studied. Three-day-old chicks did not develop enteritis after oral infection but chicks infected within 12 h of hatching developed gastroenteritis. The incubation period correlated with the inoculum size. Initially, infected chicks developed blood-and mucuscontaining stools, although watery diarrhoea often occurred late in the course of the disease. Recurrences of the enteric manifestations were common but only two out of 170 infected chicks died. C. jejuni was recovered from sites throughout the intestine; the highest concentrations were present in the caecum and large intestine. Both the upper and lower gastrointestinal tract were affected and cellular infiltration of the gastric mucosa and the intestinal lamina propria was observed. Organisms resembling C. jejuni were seen within the intestinal epithelium and lamina propria by electronmicroscopy. The newly hatched chick provides a reproducible and sensitive model of campylobacter enteritis.
