Background: Mastitis is one of the most economically important diseases of dairy animals causing heavy losses in terms of fall in milk production, decreased milk quality and additional costs for veterinary services. Mastitis is caused by a wide variety of microorganisms including bacteria, fungi, yeast and mycoplasma, of which bacteria are the most frequently isolated pathogens. Microbiological testing is necessary for identification of cause of mastitis and adaptation of control measures to prevent the disease. The aim of the presnt study was to isolate and identify major mastitis causing bacteria from clinical mastitic cases presented to Veterinary Clinical complex, FVSc. and AH, Shuhama Kashmir for treatment. Methods: A total of 200 bovine milk samples from CMT confirmed clinical mastitis cases were collected and cultured on Nutrient agar, Blood agar, Mac-Conkey agar, Eosine Methylene Blue (EMB) agar, Mannitol salt agar and Edwards media for bacterial isolation. The isolates were then subjected to biochemical tests for identification. Result: Upon microbiological testing and biochemical confirmation, the major mastitis causing bacteria isolated from clinical cases of Bovine mastitis were Staphylococcus Spp. showing highest prevalence of 46.4% followed by mixed infection with Staphylococcus and Streptococcus (20.8%), Streptococci Spp. (18.4%) and Escherichia coli (14.4%).

The present study was carried out on bovine mastitis with an objective to screen bovine milk samples around Junagadh for status of subclinical mastitis (SCM) by somatic cell count (SCC), to reveal the prevalence of staphylococcal mastitis by conventional and molecular methods and to evaluate the antimicrobial resistance pattern of the isolated Staphylococci. Total 390 bovine milk samples (180 from clinical mastitis and 210 from apparently healthy animals) were collected. Among 210 milk samples from healthy bovine, 72 samples showed SCC value andgt; 5 lakhs/mL revealing 34.29% prevalence of SCM. A primary culture isolation of 252 milk samples (72 SCM and 180 clinical mastitis) showed 38.72% prevalence of Staphylococcal mastitis. The isolated Staphylococci were further characterized by biochemical tests which showed prevalence of coagulase negative Staphylococci and S. aureus 23.08% and 15.64%, respectively. The high resistance of Staphylococci was observed against ceftriaxone and amoxicillin-salbactum which displays antibiotic usage pattern in the region. Likewise bacterial isolates studied were highly sensitive to levofloxacin which suggest judicious use of this antibiotic in treatment of bovine mastitis. All the conventionally isolated Staphylococci and S. aurues were confirmed by polymerase chain reaction targeting 16S rRNA and nuc gene respectively in shorter period of time which signifies the superiority of molecular diagnostic tools.

Bovine mastitis continues to be a leading cause of heavy economic losses in the dairy industry and a public health hazard globally. This cross-sectional study investigated the prevalence, etiologies of clinical and subclinical mastitis, and associated predisposing factors in Embu and Kajiado counties in Kenya. A semistructured questionnaire was administered to 154 smallholder dairy farmers to collect data on management practices, animal factors, and disease history. A total of 395 dairy cows were initially screened for subclinical mastitis using the California mastitis test (CMT), and milk samples were aseptically collected. Both CMT positive and CMT negative samples were analyzed using conventional bacteriological isolation and identification procedures. In the present study, the overall prevalence of mastitis based on CMT and clinical examination was 80% (316/395), out of which 6.8% (27/395) was clinical mastitis, while 73.1% (289/395) was subclinical mastitis. Based on culture, the overall prevalence of clinical and subclinical mastitis was 51.6% (815/1580), 74.4% (294/395), and 76.6% (118/154) at the quarter, cow, and farm level, respectively. From the 1574 milk samples analyzed by cultured, 1016 bacteria were yielded. The predominant bacteria were coagulase-negative Staphylococcus (CNS), 42.8% (435/1016), and in decreasing order, Streptococcus species, 22.2% (226/1016), Staphylococcus aureus, 15.7% (160/1016), and Pseudomonas aeruginosa, 5.1% (52/1016), and the least was Enterobacter species, 0.7% (7/1016), while 23.7% of the sample yielded no bacterial growth. Risk factor analysis revealed that milking mastitic cows last (p=0.002), using a clean udder drying towel for each cow (p=0.033) and previous history of mastitis (p=0.046) were significantly associated with presence of mastitis. The current study has shown a relatively high prevalence of subclinical mastitis with CNS as predominant bacteria. Therefore, control measures are urgently warranted. Management factors such as milking mastitic cows last, using a clean towel for udder drying for each cow, and culling mastitic cows should be considered and included in the Kenyan mastitis control programs.

SummaryBovine mastitis reduces the yield and quality of milk and increases the rate of culling and veterinary costs. This reduces the profitability of farm milk production but the calculation of the extent of this economic loss is complex because of the many factors involved and deficiencies in the evidence on the relationship between the disease and various production factors. This paper examines the available evidence for the UK and provides a consistent analytical framework within which the benefits arising from reduced mastitis in dairy herds constrained by quota can be considered. It is estimated that since 1970 the farms that have followed the recommended control procedures have reduced the average annual number of cases of clinical mastitis from 135 to 40 cases/100 cows each year, while the quarters remaining uninfected for a whole year has increased from 65 to 80% of the total quarters. The costs of the main control procedures (e.g. £8–60/cow for dry-cow therapy and teat dipping or spraying) are broadly covered by the reduction in clinical mastitis, leaving the benefits of reduced subclinical infection (e.g. £3810 for a 100 cow herd unconstrained by quota and achieving the average reduction in infection) as a substantial bonus. The imposition of quotas reduces the financial benefit of mastitis control but it still remains a worthwhile investment. The results of this analysis can be used to suggest maximum costs of additional new control measures produced by research. It also indicates that there is considerable value in production research which gives more precise knowledge of production Systems, thus allowing producers to respond optimally to quota cuts.

Abstract A cross-sectional study was conducted from February, 2020 to March, 2020 in selected dairy farms in Bishoftu Town to isolate and identify Staphylococcus aureus from milk samples, swab (teat swab, tank swab and bucket swab) samples. The samples were transported to microbiology laboratory and, isolation and identification of an organism was based on morphological, cultural and biochemical characteristics. Accordingly a total of 120 samples of them 58 milk sample, 58 polled teat swab sample, 2 polled tank swab sample and 2 polled bucket swab samples. Those milk samples and swab sample were collected and cultured parallel on both Blood agar and nutrient agar. Out of total samples 68/120 were well grown on both Medias and sub cultured on nutrient agar for farther identification using Primary and secondary biochemical tests. Accordingly, 68 milk samples were shown typical large, round, golden yellow colonies with hemolysis when grown on blood agar, round shaped grape like clusters are seen under microscope after stained with grams stain, and catalase positive Staphylococcus aureus with bubble formation is observed and typical yellow pigmentation on mannitol salt agar which is selective media for genus Staphylococcus. Finally, 68(56.67%) Staphylococcus aureus were identified with coagulase test with the clumping result observed. Hence, implementing hygiene conditions, creation of awareness on control and prevention of subclinical mastitis in dairy farms and conducting drug sensitivity test for Staphylococcus aureus is recommended.

The study was aimed at dairy cattle and buffaloes presented with the history of chronic diarrhea to isolate and detect Salmonella spp. Fecal samples were collected directly from the rectum of diarrheic cattle. Isolation and identification of the microorganisms was performed and confirmed on the basis of their morphology, staining, cultural, biochemical tests and sero-typing. Salmonella positive animals presented variable degree and frequency of diarrhea. Salmonellosis was confirmed in seven per cent of cattle and buffaloes suffering from chronic diarrhea. The serotype detected in the 7 Salmonella strains was Salmonella enterica subsp. enterica serovar Reading. Salmonella isolates recovered from dairy cattle had relatively variable resistance to various antimicrobial agents. The antimicrobial susceptibility pattern of the isolates showed isolates were resistant to amoxicillin, tetracycline, ampicillin, ceftriaxone. Whereas 87.5 percent, 75.0 per cent and 62.5 percent susceptible to ciprofloxacin, gentamicin and co-trimoxazole respectively. This study provides updated information on the bio-incidence and susceptibility patterns of Salmonella in dairy animals suffering chronic diarrhea. Isolation and serotyping of Salmonella enterica subsp. enterica serovar Reading is new to the study and contribute to our understanding that there is shift in increases in susceptibility of dairy herds to acquire new strains.

Isolation And Identification

Mastitis is a multietiological and complex disease causing inflammation of the parenchyma of mammary glands and is a problem in many dairy cows. The objective of this study was to isolate and identify the pathogenic bacteria that cause bovine clinical mastitis. A cross-sectional study was undertaken between November 2018 to April 2019 on a small scale and government dairy farms in Asella town. Cow’s udder and teats were physically examined to detect clinical mastitis. A total of 83 milk samples were collected from 46 cows that show clinical sign of mastitis from a total of 12 farms. Isolation and identification of major bacterial species were carried out by culturing different media and using primary and secondary biochemical tests. Out of the 83 samples collected and examined, all (100%) were positive for the cultural isolation of bacterial species. The bacteria were identified to genus and species level. Among the 83 isolates, 32 (38.6%), 24 (28.9%), and 6 (7.2%) were Staphylococcus aureus, Staphylococcus intermedius, and Staphylococcus hyicus, respectively. Other bacteria like Escherichia coli 12 (14.5%) and Streptococcus species 2 (2.4%) were also isolated. Bacillus species 2 (2.4%), Proteus species 2 (2.4%), and 3 (3.6%) of them were mixed bacterial infections. The present study revealed that both contagious and environmental bacterial pathogens were responsible for the occurrence of clinical mastitis. Proper milking practices and farm husbandry practices and future detailed studies up to the species level and on antibiotic profiles of the pathogens are needed.

The purpose of this paper was to study the etiology of mastitis, determine the antimicrobial susceptibility profile of Staphylococcus spp. and to identify the risk factors associated with infection in dairy cows in the states of Bahia and Pernambuco, Brazil. From the 2,064 milk samples analyzed, 2.6% were associated with cases of clinical mastitis and 28.2% with subclinical mastitis. In the microbiological culture, Staphylococcus spp. (49.1%) and Corynebacterium spp. (35.3%) were the main agents found, followed by Prototheca spp. (4.6%) and Gram negative bacilli (3.6%). In the antimicrobial susceptibility testing, all 218 Staphylococcus spp. were susceptible to rifampicin and the least effective drug was amoxicillin (32.6%). Multidrug resistance to three or more drugs was observed in 65.6% of Staphylococcus spp. The risk factors identified for mastitis were the extensive production system, not providing feed supplements, teat drying process, not disinfecting the teats before and after milking, and inadequate hygiene habits of the milking workers. The presence of multiresistant isolates in bovine milk demonstrates the importance of the choice and appropriate use of antimicrobial agents. Prophylactic and control measures, including teat antisepsis and best practices for achieving hygienic milking should be established in order to prevent new cases of the disease in herds.
