Association between Fur Animal Necrotizing Pyoderma in breeding farm mink (Neovison vison) and reduced fertility.

BACKGROUND: The disease Fur Animal Necrotizing Pyoderma (FNP) has since 2000 been reported in many fur producing countries including Canada, Finland and Denmark. Development of FNP is characterised by rapidly forming treatment-resistant wounds on paws and in the head region. Economic losses related to FNP have been associated with mortality and decreased fur quality as well as increased veterinary costs. Also it has been suggested that FNP may be associated with reduced production results for breeding mink. The aim of this study was to evaluate if there is an association between FNP lesions in breeding animals and reduced production results based on a retrospective cohort study. RESULTS: 1465 breeding animals (244 males and 1221 females) were followed during the breeding season 2019 on five Danish mink farms. Two farms were removed from the analysis since no occurrence of FNP appeared in the observation group. After exclusion, 846 breeding animals (148 males and 698 females) remained in the analysis and were divided into two groups: exposed (EXP) or non-exposed (N-EXP) depending on the disease history of the males during mating. Females exposed to FNP positive males during breeding in average produce 14% fewer kits (P = 0.032) and these females were also more than double as likely to produce small litters (N ≥ 3) than N-EXP females. Female's from the EXP group were introduced more times to males than females in the N-EXP group (P = 0.0001, 2.5 more times in average). Females in the EXP group did not have a statistically higher risk of becoming barren (P = 0.138) though the relative risk of becoming barren was 77% higher after encountering a FNP male. CONCLUSIONS: This study shows that FNP has more economic losses for the farms than direct loss of animals. Females in contact with males with FNP lesion during breeding have a higher risk of becoming barren, and produce significantly fewer kits compared to females whom haven't been in contact with a FNP positive male.

Burden of paediatric pyoderma and scabies in North West Queensland.

AIM: The study aims to assess the health burden of children admitted with 'scabies' to Mt Isa Hospital, the referral centre for North West Queensland, from 2006 to 2010. METHODS: This is a retrospective chart audit of admissions of children with 'scabies' including age, sex, date, residence, Indigenous status, result of skin swabs and length of stay, and the number of admissions with acute rheumatic fever (ARF) and acute post-streptococcal glomerulo-nephritis (APSGN) in that period. Financial burden was estimated from daily bed costs and transportation. RESULTS: There were 113 admissions with mean age of 23/12: 11% were <2/12 and mean stay was 4.5 days. 19 were admitted twice, 5 thrice and 2 four times. 7 individuals accounted for 25% of admissions. 'Scabies' accounted for 10.1% of medical admissions <5 years of age. Admissions increased from 10 in 2005 to 39 in 2010. The minimum cost per admission was $9584.07. Seventy-one per cent of swabs grew Group A streptococcus, all sensitive to penicillin. Sixty-three per cent of these were accompanied by Staphylococcus aureus, which was the sole organism in 18%. Sixty-four per cent of S. aureus were methicillin resistant. There were 29 admissions for ARF and 23 with APSGN. All children with 'scabies' and ARF and all but three with APSGN were Indigenous. CONCLUSION: Pyoderma and scabies are major health burdens in North West Queensland, requiring organised community-based prevention. The number of repeat admissions emphasises the futility of individual treatment.

Piodermias en el medio trópico-rural: factores de riesgo y costos de atención / Pyodermas in tropical rural environment: risk factors and costs of attention

Se ralizó un estudio transversal para determinar la prevalencia de las enfermedades piógenicas de la piel en el medio rural, su asociación a factores de riesgo y costo por atención. Se encuestaron un total de 211 casas con una población de 1,387 personas; se encontró una prevalencia del 6 por ciento de piodermias; sobre los factores de riesgo estudiados, se encontró que una persona que convive con otros pacientes con esta dermatosis tiene más de seis vece el riesgo de tener la enfermedad comparada con otra que no refirió este antecente (RR 6.6, RD 0.12 Xmh 5.6); se utilizó un modelo de regresión logística donde se incluyeron varios factores de manera simultánea
