“…(Burriel, 1997). The high prevalence of coliforms in association with caprine mastitis was consistent with the reports of Moshi et al (1998) and Ameh and Tari (2000) who reported 28.5% and 30% prevalence of coliforms from dairy goats respectively. The high prevalence of coliform infection in both the clinical and sub-clinical quarter infections recorded in this study could be associated with the unclean environment of goats maintained under rural conditions.…”

Goats are the major parts of subsidiary economy of the rural people in Bangladesh. Dairy animals including lactating goats are prone to the intramammary infection (IMI) and associated with a lot of economic impact on the farmers but the reports on caprine mastitis are very limited in inland literature. This study was undertaken to determine the udder-halve-wise comparative prevalence of clinical and sub-clinical caprine mastitis with their associated bacterial pathogens and antibiotic sensitivity patterns during the period from January to May 2010. The teat and udder of a lactating population of 1025 Black Bengal goats maintained under rural (village) condition in two different districts (Joypurhat and Mymensingh) of Bangladesh were physically examined, of which 54 (5.27%) goats had clinical mastitis which constituted as experimental animals for this study. Of the 54 selected goats, 59 (54.63%) udder-halves were affected with clinical mastitis whereas the remaining 49 (45.37%) udder-halves of the selected goats were found physically normal. Out of 59 udder-halves, 49 (90.74%) were unilaterally and 5 (9.26%) were bilaterally affected with clinical mastitis. The prevalence of clinical mastitis was found significantly (p < 0.01) higher in left udder-haves (H = 47; 79.66%) in comparison to the right (H = 12; 20.34%) udder-halves. Milk samples collected from all the 108 udder-halves were examined bacteriologically, of which 102 (94.44%) udder-halves had bacterial infection. No significant differences was observed on the status of bacterial pathogens between clinically (H = 55; 93.22%) and sub-clinically (H = 47; 95.92%) affected udder-halves, and between the single (CH = 45; 76.27% and SCH = 35; 71.43%) and mixed (CH = 10; 16.95% and SCH = 12; 24.49%) bacterial infections in both the clinical and sub-clinical mastitis udder-halves. The major bacterial pathogens isolated were Staphylococcus spp. which showed to be highest frequency (38.98%), followed by Escherichia coli (27.12%) and Bacillus spp. (10.17%) as a single clinical IMI whereas mixed IMI were also detected in both clinically and sub-clinically affected udder-halves. Antibiotic sensitivity results showed a relatively high level of resistance to ampicillin, amoxycillin and streptomycin, whereas gentamicin and ciprofloxacin were found to be the most effective drugs. These results indicate the high prevalence of sub-clinical mastitis in apparently normal quarters of lactating goats than those had clinical mastitis in other udder-halves, and therefore, there is a need for the prudent use of antibacterial in animal health and production through bacteriological and antibiogram studies in Bangladesh.

“…The majority of authors reported an association between mastitis and teat lesions ( [4,20,31,32,58], Onash et al 2 ), which are usually manifested as an outbreak [5,20,58]; furthermore, Watt [71] and Reid [59] mentioned that a possible secondary effect of orf was mastitis of the affected ewes. Nevertheless, authors did not report such an association [2,70].…”

Teat disorders predispose ewes to clinical mastitis after challenge with Mannheimia haemolytica

et al. 2006

-In order to study the effects of sheep teat disorders on the protection of the mammary gland, we used a Mannheimia haemolytica isolate, which did not cause clinical mastitis when deposited into intact teats. In the first experiment, this was deposited into the duct of teats with orf (Group A, n = 5) or papilloma (Group B, n = 3). In the second, teats were chapped and then, the organism was deposited into the duct (Group C, n = 7) or on the skin (Group D, n = 4). Ewes with healthy teats were controls (Group E, deposition into duct, n = 5; Group F, deposition on skin, n = 2). The ewes in Groups A, B or C developed clinical mastitis 5 h later, whilst the ewes in Group D developed it 2 d later; no control ewe developed clinical mastitis. In ewes with teat lesions, the organism was isolated from secretion samples and the California Mastitis Test became positive 5 h after challenge; neutrophils and lymphocytes were seen in Giemsa-stained secretion films from Group A or B ewes, whilst macrophages, neutrophils and lymphocytes in films from Group C or D ewes; neutrophils were predominating in films from Group E or F ewes. Inside the teats of Group A, B, C or D ewes, folds, hyperaemia and mucosal thickness were seen; histologically, subepithelial leucocytic infiltration was seen. In Group A or B ewes, no evidence of lymphoid tissue at the teat duct-cistern border was found. In Group C or D ewes, intense erosion and ulceration of the teat skin and conspicuous lymphoid tissue at the teat duct-cistern border, were evident; lesions characteristic of haemorrhagic mastitis were in the mammary parenchyma. In control ewes, subepithelial leucocytic infiltration in the teat duct and lymphoid tissue as above, were evident. We postulate that teat lesions can be predisposing factor to mastitis, by adversely affecting defences and speeding the process of infection and making it more severe. mastitis / sheep / teat / predisposing factor / orf

“…Nestes casos, têm-se quadros mais severos de mastite (Ameh & Tari 2000). Santos et al (2007) estudaram os aspectos clínicos e características do leite de ovelhas com mastite induzida experimentalmente com a inoculação de S. aureus, sendo observado um quadro de mastite com evolução aguda dos sintomas em todas as ovelhas, sendo o tratamento empregado (antimicrobiano intramamário e sistêmico, além de anti-inflamatório não esteroide) eficiente na recuperação dos animais.…”

“…Moroni et al (2005) realizaram um estudo sobre os fatores de risco para as infecções intramamárias em rebanhos de cabras leiteiras, sendo observado que a mastite foi mais frequente entre as fêmeas de terceira e quarta ordem de parto, e quanto ao estágio de lactação, observou-se maior positividade para animais que estavam há vários dias em lactação. Ameh & Tari (2000), também estudando os fatores predisponentes para mastite caprina, encontraram uma associação positiva entre a mastite e a presença de ferimentos na teta, porém não foram encontradas associações entre o diâmetro da teta, distância entre a teta e o solo e a prevalência de mastite.…”

Mastite em pequenos ruminantes no Brasil

Este artigo objetivou revisar as informações recentes sobre mastite em pequenos ruminantes, abrangendo etiologia, epidemiologia, aspectos de controle e profilaxia. Houve a preocupação em reunir resultados de estudos desenvolvidos no Brasil, uma vez que a mastite tem a interferência de uma série de fatores, como fatores ambientais e outros decorrentes dos sistemas de manejo empregados, condições essas determinantes para etiologia e epidemiologia da enfermidade. A prevalência da mastite em caprinos varia entre 22 e 75%, sendo que os casos de mastite subclínica são os mais frequentes. Existe uma carência de trabalhos voltados para os aspectos epidemiológicos da enfermidade no nosso país. Contudo, observa-se que a mastite vem assumindo importância cada vez maior nos rebanhos voltados para produção de carne, sendo encontrados resultados de pesquisa, principalmente na espécie ovina. A mastite estafilocócica corresponde à maior fração nas infecções intramamárias em pequenos ruminantes. O caráter zoonótico de alguns patógenos, a exemplo do Staphylococcus aureus ressalta a importância da implantação de programas de controle em propriedades leiteiras. Algumas das ferramentas de diagnóstico ainda necessitam de padronização, principalmente para espécie caprina que apresenta uma série de particularidades. Ainda são discutidas as principais estratégias de controle como o manejo de fêmeas e suas crias, os procedimentos de ordenha e a utilização de vacinas.
