RESUMO

This research aims to describe the cost-benefit analysis of selective therapy adoption for clinical mastitis based on the identification of pathogens using on-farm culture system. A survey of clinical mastitis cases was carried out in the database of a dairy herd with 500 lactating Holstein cows, during the period of September 2017 to October 2019. Variables such as frequency of cases, main pathogens identified, costs with antibiotic therapies and milk disposal were evaluated and compared between one year before (P1) and after (P2), the farm's selective therapy adoption. During the study period, 599 cases of clinical mastitis were identified, 361 in P1 and 238 in P2. The average cost of therapies was US74.33 and US91.82 for P1 and P2. Considering the two years of the study, the estimated cost of treating clinical mastitis was US45,444.31, of which US$27,559.97 were spent in P1 and US17,884.34 in P2. Based on the result of the identification of the pathogen types associated with clinical mastitis, selective therapy demonstrated cost reduction already in the first year of implementation.(AU)

RESUMO

The indiscriminate use of antibiotics in the treatment of caprine mastitis causes the appearance of resistant microorganisms, besides leaving residues in milk, putting at risk to human health. In this way, propolis is an alternative in the treatment of diseases because it has antimicrobial activity, mainly because of the presence of flavonoids in its composition. The aim of this study was to evaluate the antimicrobial potential of propolis to Staphylococcus spp. Isolated from cases of goat mastitis and qualify the crude ethanoic extract by high performance liquid chromatography (HPLC). In this study, the minimum bactericidal concentration values of propolis extracts in ethanol, ethyl acetate and hexane showed that the best concentrations capable of promoting the highest mortality of the isolates of Staphylococcus spp. from mastitis in goats, were 6250, 3125 and 1562.5µg/mL, respectively. By the microplate adherence test, it was found that 20.78% isolates were not able to form biofilm, 14.70% were classified as moderate and 64.70% were weak and none as a strong biofilm producer. Propolis in its different diluents was able to affect the formation of biofilm and showed a pronounced marked antimicrobial activity against Staphylococcus spp. strains and may be indicated for use in in vivo studies.(AU)

O uso indiscriminado de antibióticos no tratamento de mastite caprina leva ao desenvolvimento de micro-organismos resistentes que poderão estar presentes em alimentos, colocando em risco a saúde humana. Dessa forma, a própolis surge como uma alternativa para o tratamento de doenças por possuir uma ação antimicrobiana, principalmente pela presença de flavonoides em sua composição. O objetivo desse estudo foi avaliar o potencial antimicrobiano da própolis frente à Staphylococcus spp. isolados de casos de mastite caprina e qualificar o extrato etanoico bruto por cromatografia líquida de alta eficiência (CLAE-DAD). Neste estudo, os valores de concentração bactericida mínima (CBM) dos extratos de própolis em álcool etílico, acetato de etila e hexano nos isolados foram de 6250, 3125 e 1562,5µg/mL, respectivamente. Pelo teste de aderência à microplacas, observou-se que 20,78% dos microorganismos, não foram capazes de formar biofilme, 14,70% foram classificados como moderados, 64,70% em fracos e nenhum como forte produtor de biofilme. A própolis em seus diferentes diluentes foi capaz de afetar a formação de biofilme e apresentou significativa atividade antimicrobiana frente a cepas de Staphylococcus spp., podendo ser indicada para utilização em estudos "in vivo".(AU)

RESUMO

Background: Curcumin, a polyphenol derived from rhizome of Curcuma longa, has been successfully used in animals and humans due to its antibacterial and anti-inflammatory properties. Recently, a study demonstrated that curcumin ointment reduced pain, mammary tension and erythema in humans with mastitis 72 h after the treatment. Mastitis in sheep is an important problem due to restrictions associated to the use of antibiotics, affecting milk production and becoming a public health issue. Thus, the aim of this study was to verify whether the addition of curcumin in the diet of six female sheep with subclinical mastitis could have curative efficacy and benefits to animal health.Cases: Six Lacaune sheep with subclinical mastitis that persisted for more than thirty days after the parturition were used. The animals received feed containing the curcumin (60 mg/animal/day) during 10 days. On days 0 and 10 of the experiment, total blood was collected to perform the hemogram and serum biochemistry (triglycerides, cholesterol, glucose, total protein (TP), albumin, globulin, aspartate aminotransferase (AST) and urea), as well as individual milk samples for centesimal composition, somatic cell count (SCC) and total bacterial count (TBC). Total leukocytes and erythrocytes, as well as hemoglobin content, were obtained using the hematological counter CELM-CC-550. Blood smears were stained by the Romanowsky method and used for leukocytes differentiation. After ten days of treatment, five sheep were negative in the California Mastitis Test (CMT). Total erythrocytes increased, while total leukocytes decreased after the treatment. Seric levels of AST, triglycerides, cholesterol and globulins decreased, while seric levels of albumin and urea increased after ten days of treatment. No differences were observed regarding milk production and composition, as well as for SCC and TBC on days 0 and 10 post-treatment.[...]

RESUMO

Mastitis is one of the main causes of avoidable cessation of breastfeeding which increases morbidity in childhood, however, there is no uniformity in diagnostic and therapeutic criteria. The diagnosis of acute mastitis is mainly clinical. Only in certain cases, a milk culture is indicated. Regarding treatment of mastitis, it is fundamental to empty the breast, so breastfeeding should continue. It is recommended to start antibiotic therapy if symptoms persist or if there is considerable clinical impact. There is insufficient evidence of the importance of other types of mastitis (subclinical and subacute). There is also a lack of evidence that these types of mastitis are responsible for breast pain or for low infant weight gain. Furthermore, there is not enough evidence regarding the effectiveness of probiotics in the treatment and prevention of mastitis.

La mastitis es una de las principales causas de abandono evitable de la lactancia materna, con el aumento de la morbimortalidad infantil que ello supone, pero no hay uniformidad en los criterios diagnósticos ni terapéuticos. El diagnóstico de la mastitis aguda es fundamentalmente clínico, y, solo en determinados casos, está indicado el cultivo de leche. El drenaje del pecho es fundamental en el tratamiento, por lo que debe mantenerse la lactancia. Si persisten los síntomas o si existe mucha repercusión clínica, se iniciará la antibioterapia. No hay pruebas suficientes de la etiopatogenia de otros tipos de mastitis (subclínica y subaguda) ni de que sean responsables del dolor mamario o el escaso aumento ponderal del lactante. Tampoco sobre la efectividad de los probióticos en el tratamiento y prevención de la mastitis. El objetivo es realizar una evaluación de la información disponible sobre la clínica, diagnóstico y tratamiento de las mastitis para ofrecer una visión actualizada del tema

RESUMO

Mastitis es un problema relevante en las creaciones de ovejas y puede causar la producción de leche baja, bajo peso al destete, prejuicios con la muerte de los animales y los costos de tratamiento veterinario. Con el crecimiento del sector de la producción orgánica es necesario desarrollar nuevas estrategias de tratamiento y control de la mastitis. La homeopatia es una alternativa importante ya que los medicamentos homeopáticos tienen bajo costo y toxicidad, facilidad de administración y no actúan directamente sobre el microorganismo, no contribuye a la aparición de resistencias microbianas. Se investigó el desarrollo microbiológico, recuento de células somáticas (CCS), células polimorfonucleares (PMN) y las células mononucleares (MN) en leche ovina con mastitis subclínica y tratados homeopáticamente. Cincuenta animales (n=50) diagnosticados con mastitis subclínica fueron separados en dos grupos al azar. Em el grupo de control (n=25) los animales recibieron tratamiento con placebo mientras que el grupo homeopatia (n=25) recibieron el medicamento homeopático Phytolaca decandra 6 CH. Se procedió a la recogida de muestras de leche para las pruebas microbiológicas, así como por la CCS y recuento de PMNs y MNs de lós animales de los grupos control y homeopatía, en promedio, 10 días antes del inicio de los tratamientos y con 15 y 30 días después del tratamiento. Los corderos (n=50) fueron destetados y pesados 60 días después del parto. No se observo ninguna diferencia estadísticamente significativa (P>0,05) entre el CCS y frecuencias de PMNs y MNs de los grupos de homeopatía y control, antes como después del tratamiento homeopático. Pero la eficiencia fue observada sobre cura microbiológica de la mastitis, así como el aumento de peso de los corderos cuyas madres fueron sometidas a tratamiento homeopático.(AU)

Mastitis is a relevant problem in creations of sheep and can cause low milk production, low weight at weaning, losses with death of animals and veterinary treatment costs. With the growth of the sector of organic production, it is necessary to develop new strategies for treatment and control of mastitis. Homeopathy is an alternative important since homeopathic medicines have low cost and toxicity, ease of administration and not act directly on the microorganism, not contributing to the occurrence of microbial resistance. Microbiological culture, somatic cells count (CCS), polymorphonuclear cells (PMN) and mononuclear cells (MN) were evaluated in ovine milk with subclinical mastitis and treated homeopathically. Fifty (n=50) sheeps diagnosed with subclinical mastitis were separated into two groups randomly, being a control group (n=25) in which the animals received placebo treatment, whereas the other was called homeopathy group (n=25) whose animals received the homeopathic medicine Phytolaca decandra 6 CH. Were collected samples of milk for microbiological tests, as well as CCS and count of PMNs and MNs from control and homeopathy groups, on average, 10 days before the start of the treatments and with 15 and 30 days of the treatments. The lambs (n=50) were weaned and submitted to weighing 60 days after birth. No significant statistical difference (P>0,05) was verified between CCS and frequencies of PMNs and MNs of homeopathy and control groups, both before and after the homeopathic treatment. However, was noted the efficiency regarding microbiological cure of mastitis as well as the weight gain of the lambs whose ewe were subjected to homeopathic treatment.(AU)

A mastite é um problema relevante em criações de ovinos podendo ocasionar baixa produção láctea, baixo peso ao desmame, prejuízo com óbito de animais e custos com tratamento veterinário. Com o crescimento do setor de produção orgânica, faz-se necessário o desenvolvimento de novas estratégias de tratamento e controle de mastite. A homeopatia é  alternativa importante uma vez que os medicamentos homeopáticos apresentam baixos custo e toxicidade, facilidade de administração e não atuam diretamente sobre o micro-organismo, não contribuindo assim para a ocorrência de resistência microbiana. O objetivo do trabalho foi verificar a evolução microbiológica, contagem de células somáticas (CCS), de células polimorfonucleares (PMN) e células mononucleares (MN) em leite de ovinos acometidos por mastite subclínica e tratados homeopaticamente. Cinquenta (N=50)  animais diagnosticados com mastite subclínica  foram separados em dois grupos de forma aleatória, sendo um o grupo controle (N=25), no qual os animais receberam tratamento placebo enquanto que o outro foi denominado grupo homeopatia (N=25) cujos animais receberam o medicamento homeopático Phytolaca decandra 6 CH. Procedeu-se à coleta de amostras de leite para exames microbiológicos bem como CCS e contagem de PMNs e MNs dos animais dos grupos controle e homeopatia, em média, 10 dias antes do início dos tratamentos e com 15 e 30 dias pós-tratamento. Os cordeiros (n=50) foram desmamados e submetidos à pesagem 60 dias após o parto. Não foi observada diferença estatisticamente significante (P>0,05) entre as CCS e frequências de PMNs e MNs dos grupos homeopatia e controle, tanto antes quanto depois do tratamento homeopático. Porém observou-se a eficiência quanto à cura microbiológica da mastite, bem como maior ganho de peso dos cordeiros cujas mães foram submetidas ao tratamento homeopático.(AU)

RESUMO

El uso indiscriminado de antimicrobianos en animales de producción es la principal causa del aumento de la resistencia bacteriana, por lo que organizaciones intergubernamentales solicitan disminuir el uso excesivo de estos fármacos. La mastitis es causada principalmente por Escherichia coli en la zona central de Chile y, debido a que su tratamiento se concentra en el uso de antimicrobianos, se ha estudiado Aloe barbadensis Miller (Aloe vera) como una alternativa terapéutica por su efecto antimicrobiano. El objetivo de este trabajo fue evaluar el efecto inhibitorio "in vitro" de A. vera asociado a Ceftiofur en concentraciones menores a su Concentración Mínima Inhibitoria (CMI), frente a E. coli ATCC 25922 y en cepas aisladas de vacas con mastitis clínica. Se utilizó el Método de Macrodilución en Caldo. La CMI fue determinada mediante turbidez y confirmada por recuento de UFC/mL y por espectrofotometría UV-visible. Las cepas de campo fueron sometidas a un estudio de sensibilidad (Kirby Bauer) frente a un panel de antimicrobianos antes de analizar el efecto inhibitorio de A. vera. La CMI de A. vera se determinó en 60 mg/mL. La asociación de A. vera/Ceftiofur no inhibió el crecimiento de E. coli ATCC 25922. Todas las cepas de campo presentaron sensibilidad intermedia o resistencia a al menos un antimicrobiano, pero fueron inhibidas por A. vera. Esto sugiere que A. vera es más efectiva en la inhibición del crecimiento de E. coli en comparación a la asociación y podría presentarse como una alternativa terapéutica frente a mastitis clínicas causadas por E. coli.
