observations on the occurrence of pasteurella testudinis in clinical specimens from animals.		1991	1892939
chronic upper respiratory tract disease of free-ranging desert tortoises (xerobates agassizii).	seventeen desert tortoises, xerobates agassizii, with upper respiratory tract disease were examined; thirteen were euthanatized for necropsy. four normal control desert tortoises from a clinically healthy population were similarly evaluated. hemoglobin and phosphorus values were significantly (p less than or equal to 0.05) lower and serum sodium, urea, sgot, and cholesterol values were significantly higher in ill tortoises compared to controls. no significant differences in concentrations of ser ...	1991	2067052
mycoplasma agassizii causes upper respiratory tract disease in the desert tortoise.	the desert tortoise is listed by the united states government as a threatened species in part of its range. a major contributing factor in the decline of this animal has been the presence of an upper respiratory tract disease (urtd) which is characterized by a chronic disease which eventually leads to severe occlusion of the nares with viscous exudate and destruction of the respiratory epithelium. electron microscopy of infected tissues demonstrated the presence of a mycoplasma-like organism att ...	1994	7927724
molecular characterization of pasteurella testudinis isolated from desert tortoises (gopherus agassizii) with and without upper respiratory tract disease.	isolates of pasteurella testudinis recovered from clinically healthy desert tortoises (gopherus agassizii) and tortoises with upper respiratory tract disease (urtd) were characterized in an attempt to identify strains associated with disease. eighty-nine isolates, 52 from ill and 37 from healthy tortoises collected from nevada (usa), june 1990 to september 1991, were genomically fingerprinted and grouped based on ribotype similarity. twelve isolates (six from ill and six from healthy tortoises) ...	1995	7563420
extracellular neuraminidase production by pasteurella species isolated from infected animals.	a total of 721 field isolates of various pasteurella species (haemolytica, multocida, and testudinis) from various regions of the united states were examined for extracellular neuraminidase production. all strains were grown and tested in the same way. included were 372 p. haemolytica serotype 1 isolates, 181 p. haemolytica serotype 2 isolates, 63 p. haemolytica serotype 6 isolates, 101 pasteurella multocida isolates, and 4 pasteurella testudinis isolates. all pasteurella species examined produc ...	1995	7580802
herpesvirus particles associated with oral and respiratory lesions in a california desert tortoise (gopherus agassizii).	a 60-year-old captive california desert tortoise (gopherus agassizii) which died in august 1990 at the university of california, davis, california (usa), during treatment for colonic impaction had marked caseous necrosis of the oral cavity, choana, trachea, and lungs. numerous intranuclear inclusion bodies and a large number of syncytial giant cells were seen in the oral cavity and respiratory tract along with bacterial granulomas. pasteurella testudinis, streptococcus veridans, and coagulase-ne ...	1996	8827680
nasal and cloacal bacteria in free-ranging desert tortoises from the western united states.	aerobic bacteria were collected from three free-ranging desert tortoise (gopherus agassizii) populations in the eastern mojave desert (arizona, utah; usa) from 1989 to 1993, and from two free-ranging populations in the central sonoran desert (arizona, usa) from 1990 to 1994. six species of nasal bacteria and 18 species of cloacal bacteria were identified. at least one potential pathogen was found in the nasal cavity (pasteurella testudinis), and at least two potential pathogens in the cloaca (ps ...	2001	11310875
pasteurella testudinis associated with respiratory disease and septicaemia in leopard (geochelone pardalis) and other tortoises in south africa.	the first recorded isolates of pasteurella testudinis from south african tortoises kept in captivity is presented. p. testudinis was found in association with respiratory disease in affected animals.	2003	15038428
comparative studies on [pasteurella] testudinis and [p.] testudinis-like bacteria and proposal of chelonobacter oris gen. nov., sp. nov. as a new member of the family pasteurellaceae.	a collection of 12 strains, isolated from diseased tortoises and tentatively identified as [pasteurella] testudinis-like based on phenotypic characters, was compared with three reference strains of [p.] testudinis. all strains could be separated from the reference strains with respect to 16s rrna gene sequences, partial sequences of the rpob housekeeping gene and by phenotypic characters. based upon differences in 16s rrna and rpob gene sequences, the new isolates are suggested to represent a no ...	2009	19578148
a quantitative pcr method for assessing the presence of pasteurella testudinis dna in nasal lavage samples from the desert tortoise (gopherus agassizii).	pasteurella testudinis has been associated with upper respiratory tract disease (urtd) in the threatened desert tortoise (gopherus agassizii). our goal was to develop a sensitive and specific qpcr method for detecting dna from p. testudinis in nasal lavage fluid collected from desert tortoises in the field. probes for 16s ribosomal rna and rna polymerase β-subunit (rpob) genes were designed. a standard curve generated with dna extracted from known numbers of bacterial cells determined by flow cy ...	2012	23000631
testudinibacter aquarius gen. nov., sp. nov., a member of the family pasteurellaceae isolated from the oral cavity of freshwater turtles.	a total of 13 pasteurellaceae isolates from healthy freshwater turtles were characterized by genotypic and phenotypic tests. phylogenetic analysis of partial 16s rrna and rpob gene sequences showed that the isolates investigated formed a monophyletic group. the closest related species based on 16s rrna gene sequencing was chelonobacter oris ccug 55632t with 94.4 % similarity and the closest related species based on rpob gene sequence comparison was [pasteurella] testudinis ccug 19802t with 91.5 ...	2016	26554864
