“…The diagnosis of mastitis is a tedious task and can be performed using the California mastitis test (CMT) and a somatic cell count (SCC). In addition, bacteriological isolation and polymerase chain reaction identification can also be performed to confirm diagnosis [8].…”

Aim: This study aimed to investigate mastitis in dairy goat farms through the California mastitis test (CMT) and bacteriological examinations. Materials and Methods: A total of 845 goats belonging to 18 farms from four regions (Tébessa, Guelma, Souk Ahras, and Skikda) were examined. Results: Clinical examination of the mammary glands showed that 30/845 (3.55%) goats had clinical mastitis and 32 goats had half-teat inflammation. CMT subclinical mastitis (SCM) was detected in 815 goats that were presumed to be healthy. CMT showed 46 (5.64%) CMT-positive goats as well as 47 (2.88%) positive half-udders with a score of ≥2. A total of 79 bacteria were isolated and identified from the 79 bacterial positive samples. Bacteriological analyses showed that Gram-positive staphylococci were largely responsible for clinical and SCM. Coagulase-negative staphylococci, with an isolation frequency of 56.96%, were the most prevalent bacteria from all isolated organisms. The second most prevalent organism was Staphylococcus aureus at 40.50% and streptococci (2.53%) had the smallest percentage of isolation. Conclusion: It is suggested that due to the prevalence of mastitis in this species, farmers should be aware of the problem to plan preventive and control measures to reduce dairy goat losses due to this disease.

“…However, the widespread use of antimicrobial agents in the treatment and control of mastitis can cause a problem of antibiotic residues in milk leading to the risk of developing resistance in humans who consume milk or milk products (Oliver and Murinda 2012) and also in calves fed with waste milk containing antimicrobial residues (Duse et al 2014). Moreover, the widespread use of antimicrobials can cause sensitization of the normal pathogens and lead to the development of strains of bacteria resistant to antibiotics (Paterna et al 2014).…”

“…So, it is very important to consider the problems that mastitis may cause and the importance of a timely diagnosis to gain knowledge about the prevalence of the disease in the region, as well as the pathogens involved in their etiology. This information can be used to comprehensively assess the resistance and/or sensitivity of these pathogens to the antibiotics used in the treatment of this disease, using the California Mastitis Test (CMT) for the diagnosis of subclinical mastitis (SCM) as it was shown to be a useful and quick diagnostic test for field applications (Paterna et al 2014). The objective of this study was to report the prevalence of SCM in several dairy farms of a tropical region of Mexico, and the causative pathogens, as well as the sensitivity of mastitis pathogens to several antibiotics.…”

A region-wide survey was conducted in the tropical area of Tierra Caliente, State of Guerrero, Mexico to estimate the prevalence of subclinical bovine mastitis (SCM), distribution of mastitis pathogens, and in vitro antimicrobial susceptibility of different mastitis pathogens in dairy farms. In total, 1036 quarter milk samples were obtained from 259 cows at 87 different dairy farms. Collected quarter milk samples were submitted for California Mastitis Test (CMT), bacteriological examination, and testing for antimicrobial susceptibility. Overall prevalence of SCM in the studied area was 20.5 %. Prevalence in the different regions was as follows: 28 % in Arcelia municipality, 21 % in Tlalchapa municipality, 19.4 % in Pungarabato municipality, and 14.3 % in Finch Cutzamala municipality. Of all positive isolates, 97.5 % were Gram-negative bacteria. Moreover, of all positive isolates, 37.5 % were Proteus vulgaris, 25 % Salmonella spp., 12.5 % Enterobacter aerogenes, and 10 % Escherichia coli. Klebsiella pneumonia and E. coli were sensitive for netilmicin antimicrobial. However, E. coli was sensitive for pefloxacin and gentamicin with a sensitivity for pefloxacin for E. aerogenes, while Staphylococci were sensitive for gentamicin and dicloxacillin. It could be concluded that practices such as the implementation of mastitis control programs, improved milking hygiene together with an intramammary treatment with netilmicin, pefloxacin, and gentamicin antimicrobials should be considered for mastitis prevention in the study area of Tierra Caliente, in the tropical area of Guerrero, Mexico.

“…Most mastitis is caused by the presence of the bacteria Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, Escherichia freundii, Escherichia freundii, Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis, and Aerobacter aerogenes [16], [17], [18]. Research by Suwito obtained 55.55% Staphylococcus aureus, 27.77% Pseudomonas Sp, 8.33% Streptococcus sp, and 8.33% Bacillus Sp in milk from mastitis goats [3].…”

Twelve Etawah Cross-breed goats were used to determine the effect of Nothopanax Scutellaium Merr on Mastitis and Milk Quality of Etawah Cross-breed Goat. A randomized block design was used in this study with 3 treatments and 4 groups. The treatments of the research were P0 = control diet, P1 = P0 +20 g Nothopanax Scutellaium Merr, P2 = P0 + 40 g Nothopanax Scutellaium Merr. Goats were reared for one month and milk samples for mastitis were taken once a week for analysis. The results showed that giving Nothopanax Scutellaium Merr in the ration could reduce the SCC and CMT of milk (P <0.05), but did not affect the number of bacteria, pH, fat, and milk protein. This study concludes that giving Nothopanax Scutellaium Merr in the ration can reduce mastitis in goats, namely reducing SCC and CMT, and does not affect milk protein and fat.
