“…This finding runs counter to those of other studies that have been conducted nationally and internationally. Studies that have targeted the prevalence rate of contagious mastitis in Jordan showed a higher prevalence rate (35-45%) (Lafi et al 1994;Hawari and Al-Dabbas 2008;Al-Tarazi et al 2011), whereas in other parts of the world a lower rate was reported (0.5-14%) (De Vliegher et al 2012). The reasons for this discrepancy may lie in the warmer weather in Jordan as well as the lack of implementation of hygiene control measures, fly control, optimal nutrition, inter-sucking among young stock in addition to the comfort measures, especially around calving.…”

“…In Jordan, several studies have been conducted in order to investigate bovine mastitis (Lafi et al 1994;Lafi and Hailat 1998a;Lafi and Hailat 1998b;Hawari and Al-Dabbas 2008), but only one study focused on mastitis in heifers (Al-Tarazi et al 2011). In Jordan, research aimed at improving control measures for infectious diseases, especially mastitis, is still in its infancy at best.…”

ABSTRACT:Mastitis is an important cause of early culling of dairy heifers. The aims of this study were to identify microorganisms that cause subclinical mastitis (SCM) in Holstein heifers in northern Jordan, to estimate the relative importance of various microorganisms, and to examine the correlation between the somatic cell count (SCC) and the isolated microorganisms. Composite milk samples were collected aseptically from 133 Holstein heifers between Days 5 and 14 postpartum for bacterial culture and somatic cell counts. The prevalence of subclinical mastitis in this study was 57.1%. Seventy six (76) of the 133 cows tested had SCC of > 250 000 cells/ml. Bacteria were isolated from 36 (27.1%) cows. About sixty six percent (66.7%) of these isolates were cultured from cows with subclinical mastitis. Coagulase-negative Staphylococci (CNS) were the most prevalent bacteria among isolates (50%), followed by Staphylococcus aureus (22.2%), Corynebacterium bovis and coliforms (E. coli and Klebsiella pneumoniae) (5.6% each), and Streptococcus uberis (2.8%). Interestingly, the majority of the negativeculture samples (53.6%) had elevated SCC. All isolates except for the CNS group exhibited strongly elevated SCC (> 1 × 10 6 cells/ml). However, the coagulase-negative Staphylococci did not have a distinct pattern with respect to SCCs. There was a strong correlation (P ≤ 0.05, correlation coefficient 0.213) between the results of bacterial culture (culture-positive vs. culture-negative) and SCC class but not between SCC class and the type of isolated bacteria. It is concluded that subclinical mastitis appears to be a significant health issue for dairy heifers in Jordan.

“…Nigella (Nigella sativa L.) is an annual herbaceous plant belonging to the Ranunculaceae family growing in countries bordering the Mediterranean Sea and is cultivated throughout India and other tropical regions of the world (Mehta et al, 2008;Saganuwan, 2009;Cheikh-Rouhou et al, 2007). A number of reports have been published on the action of N. sativa extracts or its oil on the different bacterial isolated (Al-Haj et al, 2010;Hawari and Al-Dabbas, 2008).…”

“…Staphylococcus aureus is one of the most common causes of contagious bovine mastitis and subclinical mastitis in dairy cattle worldwide and 50-100% of herds may be infected with this pathogen (Radostits et al, 2000;Morgan, 2008) The seed of Nigella sativa Linn. (Ranunculaceae), commonly known as black seed or black cumin, is used in herbal medicine all over the world for the treatment and prevention of a number of diseases and conditions that include asthma, diarrhoea and dyslipidaemia (Hawari and Al-Dabbas, 2008).

Problem statement: Little research has focused on treatment of cows with subclinical mastitis during lactation. The seed of Nigella sativa Linn. (Ranunculaceae), commonly known as black seed or black cumin, is used in folk (herbal) medicine. Approach: Objectives of this study were to evaluate the effect of Nigella sativa Extract (NSE) with two regimens for treatment of subclinical mastitis in lactating dairy cows and to determine which regimen enhanced efficacy of it. Results: From one hundred Holstein dairy research herd in Mashhad-Iran, 83 cows with a total of 157 subclinically Staphylococcus aureus infected quarters were included. Cows were enrolled in the study based on milk somatic cell counts >200,000 mL −1 and isolation of Staphylococcus aureus in 3 samples obtained 1 week apart. About 10 cc of NSE (in paraffin: 200 mg cc −1 ) was administered via intramammary infusion. First, Cows were divided into three treatment groups. Group 1 (37 cows) received intramammary infusion at each milking (3 times daily) for 3 days with 10 cc NSE. Group 2 (24 cows) received the same intramammary infusion but only once daily for 3 days. The third, 22 cows were included as an untreated negative control group. Results in bacteriologic cure of 69.4% of quarters and 59.5% of cows (Group 1) compared to 60% of quarters and 45.8% of cows (Group 2). Test for mastitis diagnosis Somatic cell counts of milk from quarters that were not cured were higher prior to initiation of treatment than those cured. A bacteriological cure was defined as a treated infected mammary quarter that was bacteriologically negative for the presence of S. aureus at 3-7 day after the last treatment. Conclusion: All two Nigella sativa treatment regimens were significantly better than the negative control and the nine dose Nigella sativa treatment regimen treatment group was not significantly better than the three dose treatment group (p = 0.332).

“…E on the 21 st and 12 th day before calving in D1 group had an impact on reducing acute clinical mastitis forms. Hawari and Al-Dabbas (2008) point to the various forms of mastitis and bacterial agents isolated from the udders for cows in 10 farms of Holstein Friesian cattle in Jordan. Up to 15.7% reported cases of clini-cal mastitis with macroscopic changes of the mammary gland and with excretions or secretions were reported.…”

This study focuses on the effect of parenteral administration of Selenium (Se) and vitamin E on concentration of Se in plasma and the activity of glutathione peroxidase (GPx) in the blood of dairy cows during peripartal period and their effect on the reduction of clinical mastitis. From a 220 individuals Holstein herd in a two-four lactation-gestation cycle the control group (C), 1 st (D1) and 2 nd (D2) experimental group were selected. Every group consisted of 15 cows in the last phase of the pregnancy. All cows were fed with the diet containing 0.1 mg of Se per kg/DM. The blood samples from vena jugularis were collected approximately 21 days before calving (control sampling), 3 days, 12 days and 21 days after calving. On the day of control sampling and 12 days before calving in D1 group, cows were injected subcutaneously in the sprescapular region with preparation Selevit inj. a.u.v. at the doses of 48.4 mg/head of Se, and 550 IU/head of α-Tocoferol (α-Toc). In D2 group, cows were injected by the same preparation only on 21 th day before calving with the same doses of Se and α-Toc.The increase in the concentration of Se in the plasma and activity GPx in blood in D1 group on the 3 rd day and 12 th day after calving were determined. Increase in plasmatic concentrations α-Toc on 3 rd day after calving and reduction of occurrence of clinical mastitis (13.3%) as compared with control group were found.
