Mastitis is one of the most economically important diseases in dairy farms worldwide. It is particularly important in Ethiopia where no routine prevention and control practices are in place. This cross-sectional study was carried out between October 2017 and June 2018 to estimate the prevalence of mastitis, identify the associated risk factors and isolate bacterial causes in dairy farms located in southern Ethiopia using standard microbiological methods and questionnaire survey. A total of 686 lactating cows which were found in 122 selected dairy farms were investigated by physical examination and California mastitis test. The overall cow-level prevalence of mastitis was 54.2% (95% CI: 50.5 – 57.9%). Based on the study site, the prevalence was 55.7% in Hawassa, 54.3% in Arsi Negele, 52.6% each in Wondo Genet and Wolayta Soddo towns with no significant (p > 0.05) difference among the sites. The majority of mastitis cases were subclinical (48.1%) while the clinical mastitis was only 6.1%. Of the 122 herds tested, 109 (89.3%; 95% CI: 82.1 – 93.9%) had at least a cow positive for mastitis. The study showed that high parity number (OR = 1.6; p = 0.015), flat (OR = 4.5; p <0.001) and round (OR = 2; p <0.001) teat end shape, history of mastitis in preceding lactation (OR = 3.3; p <0.001), and slightly (OR = 3.5; p < 0.001), moderately (OR = 4.9; p < 0.001), and very dirty (OR = 9.2; p < 0.001) udder and legs were the major risk factors which are significantly associated with higher prevalence of mastitis. Based on the available media and reagents, the major bacteria isolated from subclinical mastitic milk samples were Staphylococcus spp. (57.3%), Streptococcus spp. (18.6%), E. coli (17.3%) and Bacillus spp. (7.5%) in order of their abundance. The present study revealed a high prevalence of mastitis, particularly the subclinical one, and the associated risk factors. Enhancing the awareness of dairy farmers, regular screening of cows for subclinical mastitis, proper treatment of the clinical cases, improving the hygienic condition of the cows, and culling of chronically infected cows are critically important to prevent and control bovine mastitis.

A cross-sectional study was conducted to determine the prevalence of bovine mastitis, associated potential risk factors and major etiological agents of clinical and sub clinical mastitis under different management condition of pastoral, agro-pastoral, ranch and farm by using California mastitis test and bacteriology. A total of 384 lactating Borana cows in Did-tuyura ranch, Yabello Pastoral and dryland agriculture research center (YPDARC) dairy farm and three districts namely Gomole, Moyale and Yabello of Borana zone were included in the study. The study revealed that overall prevalence of mastitis were 47.4 % (182/384); out of which 12 % (46/384) clinical and 35.4 % (136/384) sub-clinical mastitis whereas prevalence at quarter level was 21.48% (330/1536) of which 3% (46/1536) and 18.48% (284/1536) were clinical and sub-clinical form respectively. From the total examined quarter, 3.5% (53) of quarters had blind quarter. Prevalence in pastoral and agro-pastoral herding system (extensive management system) at cow level and quarter level were 18.9% and 10.9% respectively while prevalence in Did-tuyura ranch and YPDARC dairy farm herding system (semi-intensive) were 20% and 7% at cow level and quarter level respectively. The prevalence of mastitis significantly (P<0.05) differed with parity, stage of lactation and body condition of lactating animals. From 330 California Mastitis Test (CMT) and clinically positive milk samples there was growth of bacteria on culture media observed only in 155 (46.97%). Out of this Staphylococcus aureus accounted for 59 (38.06%) isolates followed by Streptococcus species 33 (21.29%) and Coagulase negative Staphylococcus 30 (19.35%). Due to lack of proper managements of different risk factors major pathogenic microorganisms are isolated. Proper preventive and control strategy, awareness creation on key factors of mastitis, Regular screening and culling of chronically infected cows should be practiced.

A cross-sectional study was carried out to determine the prevalence of subclinical mastitis (SCM) among medium to large scale household dairy farms in southwestern district, Jhenaidah, Bangladesh during July to December 2019. A total of 78 (n=100) lactating cows from household dairy farms (N=32) having three or more dairy cows were selected randomly as sampled populations. Milk samples were screened for SCM by using Surf Field Mastitis Test (SFMT). The prevalence of SCM varied among farm level [71.9% (95% CI: 53.3-86.3)], individual animal level [67.9% (95% CI: 56.4-86.3)] and quarter level [29.5% (95% CI: 24.5-34.9)]. Descriptive statistics represented the farmers and farm demography, characteristics of the sampled population, and overall management feature. Random Effect Logistic Regression identified, Body Condition Score (BCS) [OR=3.8 and 2.9, at cows level and quarter level respectively (BCS-2 vs. BCS-&ge;3)], and breed [OR=5.1 and 2.9, at cows level and quarter level respectively (HF&times; Sahiwal vs. HF &times; Local)] as potential risk factors. This study shows that SCM is highly prevalent in the study area, which is a major threat to the dairy industry's production performance. Regular screening by SFMT, proper hygiene, improve the management system, and farmer&rsquo;s awareness is required to control the disease.

INTRODUCTION: Mastitis is one among the top three threats faced by dairy farmers. The study was carried out to assess sub-clinical mastitis, management practices and associated risk factors for mastitis. MATERIALS AND METHODS: A cross sectional study was conducted in Chandreshwor and Archalbot VDCs of Lamjung district taking 63 dairy livestock randomly each from a herd along with questionnaire survey to respective owner. Tem ml of milk sample from each quarter was taken in a sterilized syringe for further laboratory investigation. California Mastitis Test (CMT) was performed at farmer’s shed. Organisms were identified based on colony characteristics, Gram's staining and various biochemical tests. RESULTS: On CMT, subclinical mastitis was 46.1% (n=29) and 30.15% (n=76) on animal and quarter basis respectively, however, culture showed, 28.6% and 24.2%. Streptococcal mastitis was the commonest (11.1%) followed by coliform (9.5%) and staphylococcal (7.9%). Mastitis was highest in left fore quarter (34.92%) followed by left hind (31.76%), right hind (28.57%) and right fore (25.39%). Coliform & Staphylococcal mastitis was highest in left fore and right hind quarter respectively. Most of dairy animals (86%) were on zero grazing, 30% (n=19) of the farmers had forage trees and only 29% (n=18) had known about subclinical mastitis. The average milk production was 3.5 ±1.47 liters. Subclinical mastitis was associated significantly (p<0.01) with livestock yielding more than 3 lt per lactation. CONCLUSIONS: There was high prevalence of subclinical mastitis in dairy livestock at Lamjung due to poor management, unhygienic shed, and little knowledge on subclinical mastitis.  DOI: http://dx.doi.org/10.3126/ijim.v2i2.8322 Int J Infect Microbiol 2013;2(2):49-54

A cross-sectional study was carried out from November 2015 to march 2016 on bovine fasciolosis, to assess the abattoir based prevalence, predominant species of bovine fasciolosis and associated risk factors of the disease in cattle slaughtered in Halaba municipal abattoir. A total of 384 cattle were examined using post mortem examination. Infection rates were (3.64%), 2.34%, 2.08%, and 1.82 % F. gigantic, F. hepatica, mixed and immature respectively with the overall prevalence of 9.88 % (38). F. gigantic was found to be the most prevalent species in cattle of the study area. Multivariable logistic regression analysis showed that the risk of fasciola infection was significantly higher in poor body condition animals than in medium and good body condition animals (p < 0.05). However, in terms of age, sex and breed, no statistically significant difference was found between infected animals (p > 0.05).The present study showed that bovine fasciolosis is one of the important pathogens in cattle in the study area and warrants appropriate disease prevention and control measures and further epidemiological investigations to determine the different agro ecological risk factors on the occurrence of the disease.

A cross-sectional study was conducted from October 2018 to December 2019 to estimate the prevalence of lameness in dairy cows, to  assess the causes and associated risk factors in southern Ethiopia. A total of 2009 dairy cows were visually and clinically examined, and the overall prevalence of lameness was found to be 14. 1% (95% CI=12.7-15.7). The prevalence of lameness was significantly (P< 0.05) higher in Arsi Negelle, Yirgalem, and Wolaita Sodo than in Wondo Genet and Hawassa. The prevalence of lameness was also associated with the stages of pregnancy and parity (P < 0.05). Generally, the prevalence of lameness in dairy cows was increasing with the increase in parity and stage of pregnancy. The main abnormalities observed in this study were hooves overgrowth (6%), lesions between hooves (4%), lesions on legs (2.2%), trauma (0.6%), arthritis (0.5%), and a sole ulcer (0.3%). Most of these abnormalities were mainly due to faulty  management. Hence, based on this finding it is recommended that hoof management and trimming are very essential components of lameness control. Furthermore, early detection and treatment of lame cows; training of the owners on hoof management; and  improvement of the housing are helpful to keep lameness at a lower level.

A cross sectional study was conducted to measure the prevalence; and identification of risk factors associated with clinical mastitis in dairy cows at Patiya upazila under Chittagong district of Bangladesh from 20th July to 31st December, 2013. A total of 160 farms and households were selected and 634 cows were clinically examined for determining the prevalence of mastitis and identification of risk factors. The overall prevalence of clinical mastitis was found 8.36%. Mastitis prevalence in crossbred cows was significantly (P<0.05) higher (10.09%) than indigenous cows (4.26%). The prevalence of mastitis was also significantly higher (P<0.05) with advancing age (12.5%) and in 3rd lactation period (13.62%). The cows were more prone to mastitis during 1st month of lactation (17.53%). There was a significant relationship (P<0.05) between prevalence of clinical mastitis and associated risk factors like general physical condition, herd size, frequency of dung removal, floor drainage quality and condition of floor. There was higher (P<0.01) prevalence (33.67%) of mastitis in cows having history of peri-parturient disease compared to those not having such history. Therefore, it can be concluded that minimization of risk factors of mastitis is very much necessary to control mastitis as well as to increase profitability of dairy farms.International Journal of Natural Sciences (2014), 4(1) 5-9
