Nannizziopsis guarroi, a keratinophilic fungus, is an important cause of dermatomycosis in companion lizards. At this time effective disinfection protocols are unknown and additional information is needed to prevent contamination of surfaces and equipment used in the care of these animals. To this aim, the qualitative in vitro disinfecting capability of eight commonly used household and laboratory disinfectants (Novalsan®, 3% and 10% dilutions of commercial bleach, Virkon®-S, Lysol® household cleaner with hydrogen peroxide, 70% ethanol, 409® and household cleaning ammonia) were tested at two different contact times (two and ten minutes) with three different aqueous fungal concentrations of four molecularly confirmed N. guarroi isolates. A positive control after contact with saline was also grown. After contact with disinfectant or saline, the isolates were incubated, and photographic images were taken of plate growth on day 10. Images of each plate were scored using a semiquantitative scoring system. The only disinfectant that completely inhibited growth for all four isolates at both contact times and at all three isolate dilutions was 10% dilution of commercial bleach. All four isolates grew after contact with ammonia, regardless of contact time or isolate dilution and the other disinfectants showed variable inhibition of growth that was either isolate or concentration dependent or both. In conclusion, a minimum of two-minute exposure to 10% dilution of commercial bleach is recommended for disinfection of surfaces and instruments contaminated with N. guarroi.
To determine whether rectal temperature was associated with patient mortality in clientowned guinea pigs upon presentation to a veterinary hospital. Materials and MethOds:The medical record database at a veterinary teaching hospital was searched for records of guinea pigs from January 2016 through June 2019. Guinea pigs were included in the study if a rectal temperature was measured at presentation and there was data on survival status 7 days postpresentation. If survivor status was not documented in the medical record, follow-up information was obtained from the client via telephone or email. The data was ultimately collected from 201 clientowned guinea pigs who presented for 388 independent examinations. Univariable, multivariable and sensitivity analyses were performed.results: Guinea pigs with hypothermia (<37.9°C) at presentation had a relative risk of mortality within 7 days of presentation almost 3 times greater than guinea pigs without hypothermia (relative risk: 2.88; 95% confidence interval: 1.86 to 4.48). For each 0.55°C decrease in rectal temperature, the odds of death increased 1.6 times (odds ratio: 1.64; 95% confidence interval: 1.42 to 2.89).Sensitivity analyses confirmed the robustness of the finding. clinical significance: Rectal temperature was a predictor of death for guinea pigs presenting for care at a veterinary hospital. Obtaining a rectal temperature recording should be considered for patient guinea pigs.
OBJECTIVE To characterize the epidemiologic features of rabbits with retrobulbar abscesses, including the clinical signs, diagnosis, treatment, and outcome. ANIMALS 21 client-owned rabbits. METHODS The medical record database of a veterinary teaching hospital was searched from 2011 to 2022 for records of rabbits diagnosed with retrobulbar abscesses by CT. Data reviewed included age, breed, presenting complaint, association with an odontogenic infection, aerobic and anaerobic culture results, treatment, and outcome. RESULTS The primary presenting complaint was exophthalmos (19/21 [90%]). Most cases (15/21 [71%]) were associated with an odontogenic infection. Dental disease, not associated with a retrobulbar abscess (14/21 [67%]), was a common comorbidity on CT. The most common aerobic and anaerobic isolates were Streptococcus intermedius (5/12 [42%]) and Fusobacterium nucleatum (2/12 [17%]), respectively. Surgical treatment combined with long-term systemic antibiotic therapy was performed in 9 of 21 (43%) cases. It included intraoral tooth extraction (4/9 [44%]) versus extraoral peribulbar abscess lancing with either abscess packing with antibiotic-soaked gauze (3/9 [33%]) or surgical abscess debridement (2/9 [22%]). Resolution of the clinical signs with no recurrence for at least 6 months occurred in 7 of 9 (78%) surgically treated cases. Medical treatment with long-term systemic antibiotic therapy was performed in 4 of 21 (19%) cases, and 3 of 4 (75%) resolved. Due to poor prognosis or financial concerns, euthanasia was performed or recommended in 8 of 21 (38%) cases. CLINICAL RELEVANCE On the basis of the data from this study, retrobulbar abscesses in rabbits carry a guarded prognosis. When intraoral and extraoral surgical treatment options combined with systemic antibiotic therapy were used, it resolved clinical disease in most cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
