“…L., which is considered a commensal species, has also been detected in raw milk sampled from healthy bovine mammary glands (Lafarge et al 2004). In our trial, the mean proportions of L. in group M was higher than that of other groups, which is consistent with Patel et al (2019) who reported that milk samples from subclinical mastitis cow had higher abundance of L. compared to healthy cows. Some strains of L. exhibit high adherence to bovine mammary epithelial cells, which means L. can also enter mammary gland of mastitis cows through teat and contaminant with pathogenic bacterial (Hagi et al 2013).…”

This experiment was conducted to evaluate the impact of yeast and lactic acid bacteria (LAB) on mastitis and milk microbiota composition of dairy cows. Thirty lactating Holstein cows with similar parity, days in milk were randomly assigned to five treatments, including: (1) Health cows with milk SCC < 500,000 cells/mL, no clinical signs of mastitis were found, fed basal total mixed ration (TMR) without supplementation (H); (2) Mastitis cows with milk SCC > 500,000 cells/mL, fed basal TMR without supplementation (M); (3) Mastitis cows fed basal TMR supplemented with 8 g day −1 yeast (M + Y); (4) Mastitis cows fed basal TMR supplemented with 8 g day −1 LAB (M + L); (5) Mastitis cows (milk SCC > 500,000 cells/mL) fed basal TMR supplemented with 4 g day −1 yeast and 4 g day −1 LAB (M + Y + L). Blood and milk sample were collected at day 0, day 20 and day 40. The results showed efficacy of probiotic: On day 20 and day 40, milk SCC in H, M + Y, M + L, M + Y + L was significantly lower than that of M (P < 0.05). Milk concentration of TNF-α, IL-6 and IL-1β in M + Y + L were significantly reduced compared with that of M on day 40 (P < 0.05). Milk Myeloperoxidase (MPO) and N-Acetyl-β-d-Glucosaminidase (NAG) activity of M + Y, M + L, M + L + Y were lower than that of M on day 40 (P < 0.05). At genus level, Staphylococcus, Chryseobacterium and Lactococcus were dominant. Supplementation of LAB decreased abundance of Enterococcus and Streptococcus, identified as mastitis-causing pathogen. The results suggested the potential of LAB to prevent mastitis by relieving mammary gland inflammation and regulating milk microorganisms.

“…A significant impediment to milk production by water buffalo herds is mastitis, which affects the quantity, quality, and safety of milk, causes heavy economic loss, leads to increased use of antibiotics, and impairs animal welfare (Salvador et al ., 2012). Clinical mastitis (CM) can be diagnosed by visible changes in the milk, udder, and systemic condition of animals, but subclinical mastitis (SCM) remains undetectable in most cases due to lack of clinical signs (Patel et al ., 2019). In water buffalo, SCM is around three-fold more common than CM (Ali et al ., 2014) and is responsible for declining milk production, deteriorating milk quality and reduced milk processability.…”

“…The most important aetiological agents of SCM are reported to be non-aureus staphylococci (NAS), Staphylococcus aureus , Streptococcus spp. and Escherichia coli (Dhakal, 2006; Patel et al ., 2019). Among the staphylococci, NAS have been found to be dominant pathogens in IMI (Moroni et al ., 2006; Ali et al ., 2011; Guha and Guha, 2012; Locatelli et al ., 2013) as well as in SCM and mild forms of clinical mastitis (Frey et al ., 2013; Gindonis et al ., 2013; Xu et al ., 2015).…”

Subclinical mastitis (SCM) in water buffalo is a production disease associated with decreased milk yield and impaired milk quality and safety. Water buffalo is an important livestock species in Bangladesh, but information about the occurrence and aetiology of SCM in this species is scarce. A cross-sectional study was conducted as part of the Udder Health Bangladesh Programme to (i) determine the occurrence of SCM and bulk milk somatic cell count (SCC) in water buffalo in Bangladesh, (ii) identify pathogens causing SCM and (iii) evaluate penicillin resistance in isolated staphylococci strains. Sixteen buffalo farms in the Bagerhat and Noakhali regions of Bangladesh were selected for study and a bulk milk sample was collected from each farm. In addition, 299 udder quarter milk samples were collected from 76 animals. The bulk milk samples were assessed by direct SCC and the quarter milk samples by California mastitis test (CMT). The occurrence of SCM calculated at quarter and animal level was 42.5 and 81.6%, respectively. Milk samples from 108 CMT-positive quarters in 48 animals and 38 randomly selected CMT-negative quarters in 24 animals were investigated using bacteriological culture. Estimated mean bulk milk SCC was 195 000 cells/ml milk (range 47 000– 587 000 cells/ml milk). On culture, estimated quarter-level intramammary infection (IMI) was 40.4%. The identity of isolated bacteria was confirmed by MALDI-TOF mass spectrometry. Non-aureus staphylococci (NAS) were the most common pathogens (24.7%) and, among 36 NAS tested, 36.1% were resistant to penicillin. Thus there was high occurrence of SCM on the study farms, with relatively high penicillin resistance in NAS. Further studies are needed to identify underlying risk factors and develop an udder health control strategy for water buffalo in Bangladesh.

“…Mastitis is characterized by inflammation of the mammary gland caused by infection with bacterial pathogen group (Kudi, Bray, Niba, & Kalla, 2009). Staphylococcus, Enterococcus, Escherichia, and Streptococcus are the most common bacterial genera that cause mastitis (Patel, Kunjadia, Koringa, Joshi, & Kunjadiya, 2019). Kudi, Bray, Niba, & Kalla (2009) reported that mastitis can be differentiated into clinical and subclinical mastitis, and dairy cattle often acquire the subclinical condition.…”

This study investigated the effect of betel (Piper betle L.) leaf at two physiological ages (young, 3 rd leaf, and old, 8 th leaf) at three concentrations of crude boiled-water extracts (10%, 20%, and 30%) against Streptococcus agalactiae and Escherichia coli. A completely randomized design with nesting was adopted for the six treatments and six replicates. The inhibition zone on nutrient agar media was measured. Overall there were no significantly differences. However, the inhibition zone diameters with 10%, 20%, and 30% crude water extracts of young leaves with S. agalactiae were 5.18 ± 0.99, 5.96 ± 0.34, and 6.38 ± 1.52 mm, respectively, and for old leaves, they were 5.76 ± 0.62, 5.67 ± 0.43, and 4.68 ± 0.33 mm, respectively. For E. coli, the corresponding values for young leaves were 3.96 ± 1.45, 4.54 ± 0.72, and 3.51 ± 0.48 mm, respectively, and for old leaves, the values were 3.85 ± 1.20, 4.14 ±0.68, and 2.35 ± 0.83 mm, respectively. The strongest inhibition was shown by the 30% crude water extract of young leaves against S. agalactiae.
