Study on bacterial isolation from dogs affected with malignant tumor

Abstract

To identify the bacterial isolation from dogs have cancer diseases, the samples were (throat swab and urine) have been taken from (64) dogs suffering from different cancer diseases includes (38) females and (26) males. The result of throat swab as were follows: E.coli (50%), Actenomyces pyogenes (40.6 %) , Beta Heamolytic Streptococcus group D (21.8 %) , Staphylococcus aureus (21.8 %), Klebsiella spp also Actenomyces viscosus (18.7%), S.epidermidis(12.5%), Beta Heamolytic Streptococcus groupG (9.3 %) , Proteus mirabilis (9.3 %) , Beta Heamolytic Streptococcus group B (6.2 %) , Bacillus subtilis (6.2 %), Micrococcus (6.2%) , Pseudomonas aerugenosa also Proteus vulgaris (3.1%). While the urine samples of infected doges showed the bacterial isolates of Escherichia coli (53.12 %) , Staphylococcus aureus (28.1) , Proteus mirabilis (23.4%) , Klebsiella spp (18.7 %) , Proteus vulgaris also Staphylococcus saprophyticus (7.8 %), Staphylococcus epidermidis (6.2 %) , Micrococcus , Actenomyces pyogens, Pseudomonas aerugenosa ( 3.1 %) . No significant differences were appeared at level P> 0.05 between females and males or Gram positive and Gram negative bacteria. The results of antibiotic sensitivity test to bacterial isolates from throat swabs were: E.coli have been showed a significant differences at level P <0.05 among different antibiotics, the highest was amikacin and lowest was tetracycline. Actenomyces pyogens has been significant differences at level P <0.05 among different antibiotics, the highest was amikacin, ampicillin,ciprofloxacin & the lowest was amoxicillin.Beta Heamolytic Streptococcus group D has been no significant differences at level P >0.05 among different antibiotics.The results of antibiotic sensitivity test to bacterial isolates from urine samples showed: E.coli have been significant differences at level P <0.05 among different antibiotics, the highest was amikacin and augmantin but the lowest was clarithromycin.S. aureus has been significant differences at level P <0.05 among different antibiotics, the highest were amikacin, cefotaxime & augmantin but the lowest was tetracycline.P.mirabilis has been significant differences at level P <0.05 among different antibiotics, the highest was amikacin, the lowest were ampicillin, clarithromycin, amoxicillin & tetracycline..The study showed that E.coli was the common bacteria isolated from dogs at the same time A.pyogenes was isolated too.Amikacin was the most effective antibiotic to bacteria isolated from throat swabs while cefotaxime was effective against isolated bacteria from urine.
