“…In our study yeasts were isolated at a frequency of 1.0% from the milk samples. The isolation of these microorganisms from cattle affected with mastitis has also been reported in Brazil (7), Mexico (38) http:// www.elsevier.es/en-revista-revista-iberoamericanamicologia-290-articulo-yeasts-isolation-from-bovinemammary-S1130140611000271 -aff0005and Algeria (14).

This research paper addresses the hypothesis that the incidence of various bovine mastitis pathogens is subject to change over time and across regions. The aim of the research was to determine the pathogen species that are currently the etiological agents of mastitis in Polish dairy herds. This comprehensive study was conducted in the period 2009-2017 and included all the Polish provinces, distinguishing between those with high and low numbers of dairy cattle. Over eight years 38,852 quarter milk samples were obtained from 22,587 cows with clinical and subclinical mastitis from herds located in all 16 provinces in Poland. Milk samples were cultured using standard microbiological methods. Most of them were positive for microorganisms but there was also part of bacteriologically negative and contaminated samples. Gram-positive catalase-negative cocci and staphylococci were the most prevalent pathogens. The growth of other microorganisms such as Gram-negative and Gram-positive bacilli, yeasts and algae was observed at lower frequencies. There were differences in the prevalence of microorganisms depending on the region. In the eastern part of the country a higher number of Streptococcus agalactiae infections than in other regions was observed. This paper provides the latest data on microbial species, frequency of their occurrence and regional location within Poland. The knowledge of mastitis pathogens enables appropriate treatment and to make prevention recommendations for the herds.

“…Mastitic quarters in 12 cattle were not associated with a causative bacterium for which there are several possible explanations: some bacteria, e.g., E. coli , clear spontaneously (45) before testing and go undetected; mastitis can be caused by fungi and yeasts (46) or viruses, but 16S rRNA gene sequencing is limited only to the identification of bacteria. Additionally, if the genetic data are missing from the reference database for given bacteria they will be categorized as unclassified by 16S rRNA gene sequencing (47).…”

Mastitis is one of the most costly diseases affecting the dairy industry, and identification of the causative microorganism(s) is essential. Here, we report the use of next-generation sequencing of bacterial 16S rRNA genes for clinical mastitis diagnosis. We used 65 paired milk samples, collected from the mastitic and a contralateral healthy quarter of mastitic dairy cattle to evaluate the technique as a potential alternative to bacterial culture or targeted PCR. One large commercial dairy farm was used, with one trained veterinarian collecting the milk samples. The 16S rRNA genes were individually amplified and sequenced using the MiSeq platform. The MiSeq Reporter was used in order to analyze the obtained sequences. Cattle were categorized according to whether or not 1 of the 10 most abundant bacterial genera in the mastitic quarter exhibited an increase in relative abundance between the healthy and mastitic quarters equal to, or exceeding, twofold. We suggest that this increase in relative abundance is indicative of the genus being a causative mastitis pathogen. Well-known mastitis-causing pathogens such as Streptococcus uberis and Staphylococcus spp. were identified in most cattle. We were able to diagnose 53 out of the 65 studied cases and identify potential new mastitis pathogens such as Sneathia sanguinegens and Listeria innocua, which are difficult to identify by bacterial culture because of their fastidious nature.

ABSTRAK: Mastitis adalah penyakit yang disebabkan oleh berbagai macam mikroorganisme yang menyebabkan kerugian ekonomi yang besar dan kerusakan pada industri susu karena penurunan produksi susu, peningkatan biaya pengobatan dan pemusnahan hewan produktif. Terlepas dari prevalensi mastitis mikotik yang rendah jika dibandingkan dengan agen penyebab mastitis lain, akan tetapi kejadiannya telah meningkat secara signifikan selama dekade terakhir. Dalam beberapa tahun terakhir, cendawan telah sering dilaporkan di antara agen penyebab mastitis yang lain. Meskipun kapang dan khamir tersebar secara luas di alam, namun hanya khamir yang biasanya terlibat sebagai penyebab mastitis mikotik pada ruminansia. Infeksi intra mammae seperti mastitis yang disebabkan oleh cendawan biasanya dapat sembuh dengan sendirinya secara spontan, dan infeksi umumnya tidak bersifat sistemik. Mengingat arti penting mastitis mikotik tersebut, terutama dalam hal kerugian ekonomi, dalam artikel singkat ini kami mencoba membuat ulasan untuk membantu praktisi dan peternak dalam mengendalikan dan meminimalkan insiden mastitis mikotik Kata ABSTRACT: Mastitis is a disease caused by a wide variety of microorganisms that causes large economical loses and damages to the dairy industry by decreasing milk production and through increasing costs of antibiotic treatment and culling. In spite of the prevalence of mycotic mastitis is usually very low as compared to other agents of mastitis, but it has significantly increased during the last decade In recent years, fungal agents have been frequently reported among the causative agents for mastitis. Though moulds and yeasts are widely distributed in nature, only the yeasts are usually implicated as the cause of mycotic mastitis infections in ruminants. Given the importance of the disease, especially in terms of economic losses, in this short article we try to make a review to help practitioners and farmers in controlling and minimizing the incidence of mycotic mastitis.
