			<p class="Abstract ParaOverride-1"><span class="CharOverride-4">Abstract</span> | The objective of this study was to determine the in-vitro and in- vivo activity of cranberry extracts against <span class="CharOverride-5">Escherichia coli</span> O157:H7. This strain of <span class="CharOverride-5">E. coli</span> was the most common etiologic agent of urinary tract infections isolated from patients. Filter sterilized aqueous and methanol extract of cranberry was prepared and used in the present study. The aqueous extract of cranberry produced inhibition zone ranging from (10.8 – 23.8) mm against the tested bacteria. While the methanol extract produces larger zones of inhibition (12.1 – 24.2) mm against the bacteria. The minimum inhibitory concentration (MIC) for the methanol and aqueous extract was 0.35 and 0.625 mg/ml, respectively. In vivo study involved inducing UTI in rats and then treated with (200 mg/kg B.W) aqueous and methanol extract and compared with Gentamicin treatment at a dose of (2 mg/kg B.W) subcutaneously for 14 days. Methanol extract succeeded in treated UTI caused by <span class="CharOverride-5">Escherichia coli</span> in the infected rats and prevented infection comparing with aqueous extract and Gentamicin. Food, water intake, body weight, pH and creatinine level returned to normal values after treatment with methanol extract of Cranberry fruit (200mg/Kg. B.W) comparing with aqueous extract of Cranberry fruit and 2mg/Kg. B.W. of Gentamicin. These parameters used in this current study as indicator for curing from infection. These findings indicated that cranberry extract was effective at all levels in inhibiting <span class="CharOverride-5">E. coli</span> O157:H7; thus it possesses antimicrobial activity and hold great promise as an antimicrobial agent.</p>

			<p class="Caps-on-First-Para ParaOverride-1"><span class="_idGenDropcap-1">I</span>nfection of the urinary tract (UTI) is the second most common type of infection in the body. There are estimated 150 million urinary tract infections per year worldwide (<a href="#Stamm-WE--2001"><span class="Hyperlink">Stamm, 2001</span></a>). Urinary tract infection is a bacterial infection that affects any part of urinary tract. In most cases bacteria travel to the urethra and multiply causing kidney infection if not treated (<a href="#Bethesda-MD--2005"><span class="Hyperlink">Bethesda, 2005</span></a>; <a href="#David-SH--Joseph-AS--Francisco-T--Richard-S--John-DH--Pamela-LD--2008"><span class="Hyperlink">David et al., 2008</span></a>).</p>

			<p class="Body-Text ParaOverride-1">Urinary tract bacterial infections are common in women because they have a shorter urethra than men (<a href="#Kolawole-AS--Kolawole-OM--Kandaki--Olukemi-YT--Babatunde-SK--Durowade-KA--Kolawole-CF--2009"><span class="Hyperlink">Kolawole et al., 2009</span></a>). The most common cause of UTI is Gram negative bacteria that belong to the family Enterobacteriaceae. Members of this family mostly include <span class="CharOverride-5">E. coli</span>, <span class="CharOverride-5">Klebsiella, Enterobacter</span> and <span class="CharOverride-5">Proteus</span>. <span class="CharOverride-5">Escherichia coli</span> is one of the most common bacteria capable of causing infection in humans and animals, particularly urinary tract infections (<a href="#Iroha-IR--Adikwu-MU--Esimone-CO--Aibinu-I--Amadi-ES--2009"><span class="Hyperlink">Iroha et al., 2009</span></a>). One of the most important strains of <span class="CharOverride-5">Escherichia coli</span> is O157:H7. At the first step of developing infections, bacteria must bind to the host cells and tissues, in most cases uroepithelial cells. For uropathogenic <span class="CharOverride-5">E. coli</span>, Type1 ﬁmbriae (<a href="#Bahrani-Mougeot-FK--Buckles-EL--Lockatell-CV--Hebel-JR--Johnson-DE--Tang-CM--Donnenberg-MS--2002"><span class="Hyperlink">Bahrani et al., 2002</span></a>) and P-ﬁmbriae are proteinaceous macromolecules that facilitate the adhesion of <span class="CharOverride-5">E. coli</span> to uroepithelial cells (<a href="#Gunther-NW--Lockatell-V--Johnson-DE--Mobley-HL--2001"><span class="Hyperlink">Gunther et al., 2001</span></a>; <a href="#Mulvey-MA--2002"><span class="Hyperlink">Mulvey, 2002</span></a>). Resistance to the antimicrobial agents is recognized as a major global public health problem, infectious diseases are for approximately one–half of all cases of death in different beings (<a href="#Iwu-MW--Duncan-AR--Okunji-CO--1999-"><span class="Hyperlink">Iwu et al., 1999</span></a>). As resistance becomes more common there becomes a greater need for alternative treatments (<a href="#Goossens-H--Ferech-M--Vander-SR--Elseviers-M--2005"><span class="Hyperlink">Goossens et al., 2005</span></a>). </p>

			<p class="Body-Text ParaOverride-1">The most prevalent Gram-negative pathogens, such as <span class="CharOverride-5">Escherichia coli, Salmonella enterica, and Klebsiella pneumoniae,</span> cause a variety of disease in humans and animals, and a strong crrelation between antibiotic resistance developmenthas been observed over the past half-century (<a href="#Brotze-Oesterhelt-H--Brunner-NA--2008"><span class="Hyperlink">Brotze-Oesterhelt et al., 2008</span></a>; <a href="#Jacoby-GA--2009-"><span class="Hyperlink">Jacopy, 2009</span></a>). Cranberry (<span class="CharOverride-5">Vaccinium macrocarpon</span>) fruits and juice have been used to prevent urinary tract infection (UTI) and to protect humans against oxidative stress (<a href="#Klein-MA--2005-"><span class="Hyperlink">Klein, 2005</span></a>). Therapeutic value of Cranberries used in trade medicine derives from the presence of mainly vitamin C, dietary fiber, glucose and fructose, flavonoids (flavonols, anthocyanins, and proanthocyanidins), and gallic, benzoic, citric, and oxalic acids. The medicinal effectiveness and safety of cranberry juice/pills have been critically evaluated (<a href="#Jepson-RG--Craig-JC--2008"><span class="Hyperlink">Jepson and Craig, 2008</span></a>). Cranberries seem to be the most effective in preventing the adhesion of <span class="CharOverride-5">E. coli </span>to uroepithelial cells, which is responsible for 85% of UTI. </p>

This was obtained by using 10 g of dried fruit placed in 100 ml of methanol in a conical flask, and then kept on a rotary shaker at 190 - 220 rpm for 24 h. After 24 h, then filtered and centrifuged at 4500 rpm for 15 min. The supernatant was collected and the solvent was evaporated by using rotary evaporator to get rid of methanol and also AOAC standard method proposed to determine the present of methanol in the final extract after drying (<a href="#Horwitz-W.-AOAC-Official-Method-958.04--2000-."><span class="Hyperlink">Howitz, AOAC Standard, 2000</span></a>) and then stored at 4°C in airtight bottles for further studies.</p>

			<p class="Body-Text ParaOverride-1">For aqueous extraction, 10 g of dried powder was placed in 100 ml de-ionized water in beakers and heated for 10 min on a magnetic stirrer hotplate until the temperature reached 95°C. Subsequently, the mixtures were allowed to cool for 10 min to increase extraction of active compounds. Extracts were then filtered through filter paper (What man size 41) to remove smaller particles using a Buchner funnel. Each final extract was stored in a dark screw-cap sterile container (this is done because phenolics are photo-sensitive) and then stored at 4°C for 24 h before use (<a href="#Ajayi-AO--2013"><span class="Hyperlink">Ajayi, 2013</span></a>).</p>

Twenty-five ml of the inoculated Mueller Hinton agar was distributed into sterile Petri dishes of each. The agar was left to setile for 10 minutes to allow solidifition the agar, and in each of these plates 6 well, 6 mm in diameter were cut using a sterile Pasteur pipette and the agar discs were removed by a sterile forceps, the wells were filled with 0.1ml of each concentration of 10, 20, 40, 60, 80 and 100 mg/ml of Vaccinium macrocarpon extracts using microtiter-pipette, that allowed to diffuse at room temperature for two hours. The plates were then incubated in the upright position at 37 Co for 24 hours. Three replicates were carried out for each concentration extract and the activity of plant extract was determined by measuring the diameter of inhibition zone around each well by millimeter against the tested organism. The average of triplicates results and standard errors means values were tabulated. The same technique was used for determination of Gentamicin, and Ciprofloxacin by using the concentrations of 10, 20, 40, 60, 80 and 100 mcg/ml.

This result was different from that obtained by Mohammad and Kambiz (2010), who obtained a double concentration of MIC against <span class="CharOverride-5">E. coli</span> O157:H7.

Twenty four hour after induced infection in experiment animals were suffered from anorexia, dehydration, fever and their urine became dark yellow. Unusual frequency of urination increased gradually from the first day after infection, foul smelling and cloudy urine in infected groups. The animals of group D which received methanol extract showed faster recovery and clinical signs were improved after 7 days. The animals of groups C and E which received aqueous extract and Gentamicin respectively did not showed complete recovery at the end of 7 days of treatment and clinical signs were relatively mild until 14 days of  treatment, the signs began subside. Group B (untreated group) showed; frequent urination, dyspnoea, emaciation, rough body coat, and poor body weight gain and reduced elasticity of skin indicating dehydration. Morbidity (infection) rate was 100% in infected groups; the highest mortality rate was 75% in group B (+ve control) along the period of experiment, while 25% mortality rate was recorded in group C. Groups D and group E did not showed any mortality, and did not lose any animals during the period of experiment.</p>

			<p class="Body-Text ParaOverride-1">It can be concluded that anorexia during infection may serve to reduce the availability of nutrients essential to the growth of pathogenic organisms. The results of the present study were accepted by most investigators, for instance <a href="#Forrester-A--2002-"><span class="Hyperlink">Forrester (2002)</span></a> reported in rat that infection with <span class="CharOverride-5">E. coli </span>gave clinical signs develop in steps begin with fever, loss of appetite, unusual frequency of urination signs of dehydration is appear (sunken eyes, dry mucus membranes, rough hair), unable to rise body, loss of consciousness, dehydration is usually severe, the course of the disease is rapid from weakness, dehydration to death can be less than 24 hours. However <span class="CharOverride-5">E. coli</span> O157:H7<span class="CharOverride-5"> </span>endotoxin and interlukin-1 will increase the renal excretion of arginine vasopressine. It is possible that injection of bacterial endotoxin or IL-1 will induce changes in fluid intake that would be reflected as an increase intake of liquid and water there for the increase of water intake in infected groups may belong to the increase of body temperature and diarrhea which lead to loss fluids and dehydration (<a href="#Mccarthy-DO--Klugr-MJ--Vander-AJ--1985"><span class="Hyperlink">Mccarthy et al., 1985</span></a>).</p>
		  <p class="Body-Text ParaOverride-1">&nbsp;</p>
			<p class="Body-Text ParaOverride-1">Loss of appetite is a common manifestation of acute infectious illness and it is believed to contribute to the negative nitrogen balance and loss of body weight that is seen during infection. The frequency of anorexia occurs with infection suggests that it may be a part of the acute phase response. It seems that food intake should be voluntarily suppressed at time when metabolic rate can rise 10-13% for each degree centigrjade rise in body temperature. Infection induced anorexia is believed to be the major  factor in the negative nitrogen balance and body weight loss that so often occurs with infection. This hypothesis tested by injection of <span class="CharOverride-5">E. coli </span>O157:H7 endotoxin into rat which resulted both an elavation in body temperature  and depression in food intake (<a href="#Mccarthy-DO--Klugr-MJ--Vander-AJ--1985"><span class="Hyperlink">Mccarthy et al., 1985</span></a>). The decrement in food intake in some of the present study groups is in agreement with <a href="#Patton-JS--Peters-PM--McCabe-J--Crase-D--Hansen-S--Chen-AB--Liggitt-D--1987-"><span class="Hyperlink">Patton et al., (1987)</span></a> that referred that suppression of food intake and anorexia commonly occur during infection. Loss of appetite in infected rats plays a vital role in host defense as a part of a purposeful redistribution of nutrients that contributes to “nutritional immunity” during infection. There is evidence that suppression of food intake may be caused by endogenous cytokines, in fasted rats, both <span class="CharOverride-5">E. coli</span> endotoxin and interleukin-1 have been shown to suppress food intake. Loss of body weight after <span class="CharOverride-5">E. coli</span> infection studied in rats by <a href="#Voisin-L--Breuille-D--Combaret-L--Pouyet-C--Taillandier-D--Aurousseau-E--Obled-C--Attaix-D--1996"><span class="Hyperlink">Voisin et al. (1996)</span></a>, they found similar results to those in the present study when they recorded that the highest body weight loss happened in second period of infection with <span class="CharOverride-5">E. coli</span> which reached to 35 gm, the acute septic phase was characterized by a marked decrease in food intake reached to 25% of the pre-infected food consumption.  Protein breakdown was elevated during the acute and chronic septic phases when significant muscle wasting occurred. Among other metabolic disturbances, sepsis causes a severe and persistent loss of body protein, much of which originated from skeletal muscle.</p>
		  <p class="Body-Text ParaOverride-1">&nbsp;</p>
			<p class="Body-Text ParaOverride-1">These results gave an evidence that there was effect of cranberry extract on body weight of rat when it was used it in therapeutic doses, this result is supported by <a href="#Faustino-R--P-rez-L-P--Avier-JH--Peter-C--2009"><span class="Hyperlink">Faustino et al. (2009)</span></a> who studied the possible effect of oral administration of cranberry extract in rat body weight and food intake, which they were affected by the extract administration in doses reached to 200 mg/kg two months, therefore the body weight changes was increase in the experimental groups. Therefore cranberry extract had possible effect on body weight and food consumption in rats because cranberry is considered has an antibacterial effect and change of pH urine to acidity this mechanism leads to reduce bacterial number in urine and finally lead to increase food intake and subsequently lead to increase body weight.</p>

			<p class="Heading-2--History-in-MM-">Serum Creatinine</p>
			<p class="Body-Text ParaOverride-1">Different levels of serum Creatinine in all infected rats are listed in (<a href="#Table-4-"><span class="Hyperlink">Table 4</span></a>) There was a significant increase (p&lt;0.05) in all groups B, C, D and E in contrast to group A (-ve control). The serum Creatinine values return to normal after 7days of treatment with extract when compared  with control A (-ve). On the other hand, group B (infected none treated) and group E (treated with Gentamicin) did not succeed to return serum Creatinine levels to normal levels along period of experimental.  The results of the current study were in agreement with <a href="#Al-Murayati-HY--Al-Ani-IM--1997-"><span class="Hyperlink">Al-Murayati (1997)</span></a> who showed an increased level of serum Creatinine in infected rats with <span class="CharOverride-5">E. coli</span> O157:H7 and found suffering from severe destruction in many kidney parts. The present study showed that the administration of Gentamicin to rats once daily for 7 and 14 days reduces glomerular function, as reflected by increased serum creatinine concentrations. Aminoglycoside-induced nephro-toxicity is characterized by a decrease in the glomerular filtration rate and direct tubular injury. The interaction between the cationic aminoglycoside and membrane anionic phospholipids is considered to be the first cytotoxic step. Some studies like <a href="#Ekor-M--Farombi-EO--Emerole-GO--2006-."><span class="Hyperlink">Ekor et al. (2006)</span></a> suggest that aminoglycoside antibiotics can stimulate the formation of reactive oxygen species, which may be directly involved in Gentamicin-induced acute renal failure and membrane lipid peroxidation. Finally significantly higher levels of (proanthocyanins) that found in cranberry juice that limit of quantification and did not exceed approximately 0.7 mg/dl of serum Creatinine  in the body (<a href="#Tracy-TS--Kingston-RL--2007"><span class="Hyperlink">Tracy and Kingston, 2007</span></a>).</p>

			<p class="Heading-2--History-in-MM-">Urine pH </p>
			<p class="Body-Text ParaOverride-1">Normally pH values of rat urine are between 3.5 and 4.4 (<a href="#Stefan-C--2005"><span class="Hyperlink">Stefan, 2005</span></a>). Different levels of pH in all groups are listed in (<a href="#Table-4-"><span class="Hyperlink">Table 4</span></a>). There was significant increase (P&lt;0.05) in all infected groups comparison with groups A (-ve). After 7 days of treatment with methanol extract, the pH values returned to normal when compared with control group A (-ve) while group C (treated with aqueous extract) and group E (treated with Gentamicin) showed decreased in pH values after 14 days of treatment while group B (infected not treated) didn’t showed any changes in pH values throughout the experimental. These results agreed with those of <a href="#Stefan-C--2005"><span class="Hyperlink">Stefan (2005)</span></a> who stated that the <span class="CharOverride-5">E. coli </span>O157:H7<span class="CharOverride-5"> </span>was inhibited when pH of urine became more acidic and when rats treated with cranberry the urine became more acidic which led to inhibition of bacterial growth in the urine.
