Antibiotics susceptibility of bacterial pathogens associated with otitis media

One hundred twenty patients with chronic suppurative otitis media (CSOM) in Basrah, 65(54.2%) males and 55(45.8%) Females, with male: females ratio (1.2:1) and 60 individual without ontological problems as control group were included in this study, which was done during the period of March, 2009 to January, 2010. This Include collection of aural swab samples, culturing of samples, identification of causative agents species and antibiotic sensitivity. Gram ' s negative bacteria were the commonest microorganisms; it comprises (60%). Pseudomonas aeruginosa was common causative agent (19.04%), followed by Staphylococcus aureus (16.7%) and Klebsiella spp. (14.3%). Mixed infection was found in high percent (74%), in which P. aeruginosa and other microorganisms were more common. The antibiotic sensitivity pattern showed that P. aeruginosa was sensitive to Ciprofloxacin, amoxicillin +clavulanic acid and gentamicin, while other is appeared resistant, S. aureus was sensitive to ciprofloxacin, amoxicillin+clavulanic acid, erthomycin, cephalexine and it is resistant to pencillin and ampicillin, klebsiella species were sensitive to ciprofloxacin, amoxicillin +clavulanic acid ,gentamicin,while resistant to tetracycline

Some reproductive characters of the fantail goldfish Carassius auratus auratus females from rearing ponds in Basrah, Southern Iraq.

This study was carried out to determine some reproductive characteristics of the fantail goldfish Carassius auratus auratus females (standard length 69-224 mm. and total weight 21.1- 255.35 g.) from rearing ponds in Basrah province, Southern Iraq. Standard length, total weight, gonad weight, absolute fecundity, relative fecundity, gonadosomatic index (GSI) and egg diameter were determined from October 2010 to April 2011 in 77 fantail goldfish females. Results showed that the studied reproductive parameters increased gradually from October, to attain peak in March and decreased again thereafter. Absolute fecundity ranged between 2877- 357246 eggs, GSI 7.28-19.11 and egg diameter 298-1006 micron. Regression relationships between the various studied morphometric and reproductive parameters were calculated and the importance of these results to the culturists of this commercially important ornamental fish species was discussed
