“…No significant differences between two islands in the number or type of bacteria were noted. Most of the isolated Gram-negative, opportunistic microflora has already been described as a potential cause of diseases in animals and humans (DRAPER et al, 1981;HARRIS and ROGERS, 2001;CHEN et al, 2011). Considering an increasing popularity of reptiles in Croatia, this aspect of human infection should not be overlooked.…”

The aim of this study was to identify oral and cloacal aerobic flora of four-lined snakes (Elaphe quatuorlineata) from Croatian islands Cres and Olib to get better insight into bacteria and fungi potentially harmful to both the animals and the people getting in contact with those animals. Oral and cloacal swabs were taken from a total of 20 snakes and analyzed by standard microbiology and by Real-Time PCR method for Chlamydia spp. identification. Neither Salmonella spp. nor Chlamydia spp. were detected, but some potentially human pathogens, such as Aeromonas hydrophila, Escherichia coli, Serratia marcescens and Stenotrophomonas maltophilia, were isolated. Some of fungi detected, such as Candida albicans, Aspergillus flavus and Cladosporium sp., have already been described as secondary causative disease agents in reptile collections. To the author's knowledge this study is the first survey of aerobic microflora of four-lined snakes.

“…(PALLERONI;BRADBURY, 1993;OLIVEIRA-GARCIA et al, 2002), can be found in a variety of geographical regions, environments and decomposing organic materials (rivers, wells, reservoir lakes, soil, raw milk, frozen fish, eggs, animal carcasses, hospital equipment and environment, semen, frozen bovine embryos, human anatomical sites and urine) (KONEMMAN et al, 2001;ALMEIDA et al, 2005). It has also been reported in goats and crocodiles (HARRIS; ROGERS, 2001) and in fish like Seriola quinqueradiata (FURUSHITA et al, 2003) and Ictalunes punctatus (DU et al, 2011). Depending on the strain isolated, it may have pathogenic activity against both humans and animals (CHANSANG et al, 2010).…”

The microbiota present in Stomoxys calcitrans larvae may assist their survival in contaminated environments through production of inhibitory substances. Bacteriological identification methods, the polymerase chain reaction (PCR) and scanning electron microscopy (SEM) were used to detect a bacterium naturally present in mucus and macerated S. calcitrans larvae. The antifungal activity was determined based on the results from disk diffusion tests on an artificial solid medium. The bacterium was identified as Stenotrophomonas maltophilia and presented antifungal activity against Beauveria bassiana sensu lato isolates CG 138, CG 228 and ESALQ 986. This result suggests that the larval microbiota is a factor that can compromise the use of B. bassiana s.l. fungus for biological control of S. calcitrans larvae.Keywords: Stenotrophomonas maltophilia, Stomoxys calcitrans, antifungal activity. ResumoA microbiota presente em larvas de Stomoxys calcitrans pode auxiliar na sua sobrevivência em ambientes contaminados, devido à produção de substâncias inibidoras. Métodos bacteriológicos de identificação, reação em cadeia da polimerase (PCR) e microscopia eletrônica de varredura (MEV) foram utilizados para detectar uma bactéria naturalmente presente no muco e macerado de larvas de S. calcitrans. A atividade antifúngica foi baseada nos resultados obtidos no teste de difusão em meio sólido artificial. A bactéria foi identificada como Stenotrophomonas maltophilia e apresentou atividade antifúngica contra os isolados CG 138, CG 228 e ESALQ 986 de Beauveria bassiana sensu lato. Estes resultados sugerem que a microbiota larval é um fator que pode comprometer o uso de B. bassiana s.l. no controle biológico de larvas de S. calcitrans.

“…1 Despite doubts about its pathogenicity, the bacterium has also been implicated in chronic respiratory disease among horses, dogs, and cats 1 ; lymphadenitis in goats 8 ; and acute septicemia in a crocodile. 7 The clinical, laboratory, gross, and microscopic findings that are indicative of pyogranulomatous hepatitis caused by S. maltophilia in a buffalo are reported in the current study.…”

“…Systemic infections due to this bacterium are generally rare. A previous study 7 reported a case of septicemia that was associated with S. maltophilia in a West African dwarf crocodile. The bacterium was seen histologically in lesions of the valvular endocardium and in foci of necrosis in the myocardium, liver, spleen, pancreas, kidney, and intestinal tract of the dead animal.…”

Stenotrophomonas Maltophilia as a Causal Agent of Pyogranulomatous Hepatitis in a Buffalo (Bubalus Bubalis)

Abstract. A 7-year-old female buffalo (Bubalus bubalis) from a local herd in Serres, northern Greece, was presented to a private veterinary clinic with a chronic loss of appetite for 15 days. The clinical examination revealed high fever (41.5uC), lethargy, yellow discoloration of skin and mucous membranes, an abdomen that appeared to be empty, hyperactive rumen motility, and tachypnea. A biochemical profile revealed an elevated total bilirubin concentration and hepatic enzyme activities, whereas globulin, creatinine, and glucose concentrations were within the reference intervals. The animal received a 12-day course of treatment with intramuscular administration of ampicillin and corticosteroids. However, no significant clinical improvement was achieved, and the buffalo was euthanized. Gross necropsy lesions included serous atrophy of adipose tissue and hepatomegaly. Microscopic lesions included necrotizing pyogranulomatous hepatitis with thrombosis, hemorrhages, edema, and fibrosis. Small, nonpigmented, bacterial colonies were harvested in pure culture from the liver and were confirmed as Stenotrophomonas maltophilia by polymerase chain reaction. The bacterium was sensitive to ciprofloxacin, enrofloxacin, colistin, polymyxin, trimethoprim/sulfamethaxazole, and chloramphenicol. In contrast, resistance to ticarcillin, piperacillin, imipenem, ceftazidime, amikacin, gentamicin, tobramycin, and tetracycline was displayed. The bacterial strain carried the L1 metallo-b-lactamase (L1) and tet35 genes, which contribute to high-level resistance to b-lactams and tetracycline, respectively. Although S. maltophilia is widely believed to be a contaminant, the present report suggests that the isolation, identification, and susceptibility testing of this multidrug-resistant bacterium may be of clinical importance in diagnostic samples.
