This study aimed to guide professionals working in veterinary laboratories, outpatient clinics, medical centers, and hospitals regarding the biosafety measures that should be adopted during the novel coronavirus (SARS-CoV-2) pandemic. While the population is not yet fully immunized by vaccines, the adoption of biosafety measures is essential to control the spread of circulating strains of the new coronavirus. Thus, the importance of professionals and collaborators following biosafety guidelines in different veterinary work environments is highlighted. The main protocols on biosafety to be adopted include frequent handwashing with water and soap or using 70% alcohol-based hand sanitizers, using personal protective equipment (PPE) (including gloves, lab coat, face mask), avoiding the contact of the hands with mucous membranes (eyes, nose and mouth), not sharing personal objects, keeping environments clean and well ventilated, social distancing of 1.5 m between individuals, and maintaining objects and surfaces regularly clean throughout the work environment. The transformation of work processes, such as various biosafety practices, is necessary within the context of the COVID-19 pandemic and improves the safety of professionals in their work environment and other people and animals, decreasing contamination risks in order to reduce the spread of this viral agent.
The bacterium Streptococcus dysgalactiae is part of the group of streptococci, classified as Gram-positive cocci. Found mainly in the oral cavity, genitalia and in the skin of the mammary gland of animals and in its permanent environment, it is classified as an environmental pathogen, which is characterized as an opportunistic invader of the udder. Mastitis caused by this agent, usually presents in the clinical form of the disease, with infections of acute and severe character. The objective of this work was to identify the bacterial agent that causes bovine mastitis in the Northwest region of the State of Rio Grande do Sul, to isolate Streptococcus dysgalactiae and to determine its sensitivity profile against the main antimicrobials used in this region for the treatment of bovine mastitis. 917 mastitic milk samples were received for culture and antibiogram examination at the Veterinary Microbiology Laboratory of Unijuí, from January 2012 to May 2018. Streptococcus dysgalactiae, responsible for causing environmental mastitis, mainly of an acute nature, was isolated in 9 cases of mastitis, presenting a sensitivity profile, with high antimicrobial efficiency (100% sensitivity) for ciprofloxacin, cephalothin, enrofloxacin, gentamicin, norfloxacin and sulfazotrim. Thus, it is concluded that the prevalence of bovine mastitis caused by environmental agents, among them S. dysgalactiae in the Northwest region of the State of Rio Grande do Sul is high.
Anaplasmosis is a disease caused by the bacterium Anaplasma marginale, transmitted mainly by ticks in cattle herds around the world, in addition to transmission by hematophagous and iatrogenic insects. In this work, the objective was to describe an outbreak of anaplasmosis in six adult dairy cattle in the region of Ijuí-RS, showing success in the clinical resolution for patients treated with enrofloxacin-based antimicrobial therapy. According to the anamnesis, the animals that had died on the property, had shown clinical signs such as: loss of appetite, jaundiced mucous membranes and on the other day the clinical condition worsened, until death. The animal seen in a veterinary consultation, showed the same clinical signs and the clinical examination, apathy, dehydration, pallor, jaundiced ocular, oral, nasal and vulvar mucous membranes, dehydration and hypersalivation. The main complaint for the consultation was the reluctance to eat, weight loss and decreased milk production, considering that the animal had already been treated for bovine parasitic sadness 2 days ago, with diminazene diaceturate and oxytetracycline. However, the diagnosis was confirmed by blood smear and the necropsy findings performed on another animal that died on the same property, with jaundiced mucous and serous, with an excessive increase in the size of the liver, spleen and gallbladder, as well as the presence of blood with an aqueous aspect and by the blood smear which resulted in the presence of bacteria of the genus Anaplasma. Antimicrobial therapy based on enrofloxacin associated with lactated ringer fluid therapy, blood transfusion, vitamins and organic modifier was instituted for the treatment of bovine patients. Due to other cases already reported in the region, it is believed that there are some strains of the bacteria Anaplasma marginale, which are resistant to oxytetracycline, thus, enrofloxacin appears as a new treatment alternative for dairy cattle with anaplasmosis, refractory to the use of oxytetracycline.
Abstract. In cattle, squamous cell carcinomas (SCC) are the most frequent malignant tumors. Where the animals most affected are those that have depigmentation in the mucocutaneous region. This study aimed to report the clinical case of suspected third eyelid squamous cell carcinoma in a Holstein cow. Clinical care was carried out on a female bovine, of the Dutch breed of approximately 5 years of age, in the anamnesis, the owner reported that six months ago there had been an increase in volume on the side of the animal's left eye. Upon general clinical examination, no changes in physiological parameters were detected. On specific eye examination, it was found in the left eye that the third eyelid had a bulky mass, with mucopurulent secretion. The treatment performed in this service was through surgery to remove this eye mass, suspected of squamous cell carcinoma. Where the tumor was removed with the maximum safety margin possible so that it would not return again. After topically applied to the affected eye, antibiotic and associated anti-inflammatory, Terra-Cortril® Spray (oxytetracycline hydrochloride and hydrocortisone), for 7 days / BID. In this case, the suspicion of SCC in the third eyelid is concluded through anamnesis and macroscopic lesions visualized on clinical examination. The treatment was surgical excision, but histopathological analysis was not performed, being of total importance for obtaining a conclusive diagnosis. Thus, it is concluded that the follow-up of the case after treatment is extremely important, due to the assessment of the clinical condition.
The goat milk industry has unquestionably grown in recent years due to the high demand for dairy products, which are considered nutritious and hypoallergenic. As a result, security measures are required in the production chain to provide consumers with safe products, although the concept of biosecurity is still incipient in Brazilian goat farming. Therefore, this study aimed to review the main biosecurity measures applied to dairy goat farms and suggest a program that contemplates these measures to promote animal health and welfare, given that biosecurity bolsters environmental sustainability and improves this agricultural sector. Biosecurity programs (BP) are composed of a set of measures and procedures aimed at herd health and applied in all stages of animal husbandry, interacting with different sectors that make up the production system and providing a set of policies and operational norms to protect herds against potentially pathogenic agents. Thus, BP require planning, execution, monitoring, audits, updates, understanding of the procedures, and awareness of those involved in the production chain. In addition, it includes continuing education programs and the development of contingency plans for specific emergencies. The information included in this study provides input to dairy goat farms to implement practices that improve the productivity of this agricultural sector.
As mastites são um dos principais problemas enfrentados na pecuária leiteira, está se caracteriza pela inflamação da glândula mamária, com etiologia de origem bacteriana, fúngica, viral dentre outros. No presente estudo objetivou-se relatar a ocorrência de um caso de mastite bovina causada por Aspergillus spp. e Nocardia sp, em co-infecção na região Noroeste do Rio Grande do Sul. A amostra de leite foi analisada no laboratório de Microbiologia Veterinária da Unijuí semeada em ágar sangue ovino 5% e ágar McConkey. Na análise visual do fungo, observou-se o crescimento de uma colônia branca, de aspecto aveludado, com aproximadamente 2 cm de diâmetro e com seu anverso de coloração esverdeada, ao exame microscópico, observou-se hifas ramificadas e septadas, vesícula, fiálides e conídios, compatíveis com características aspergilares, caracterizando o isolamento do Aspergillus spp. Na mesma amostra, observou-se visualmente a presença de colônias pequenas, de aspecto liso, coloração branco-opaco e firmemente aderidas ao ágar, com as seguintes características, colônias gram-positivas, filamentosas e ramificadas, com predominância de formatos bacilares, permitindo a identificação do gênero Nocardia sp. A partir deste caso nesta região, é possível enfatizar a grande importância de se realizar a identificação do agente causador da mastite, pois as mastites causadas por fungo, como o Aspergillus spp., concomitantemente com bactéria do gênero Nocardia sp., embora sejam de baixa ocorrência, causam diversos prejuízos econômicos, pela queda na quantidade e qualidade do leite produzido.
