Honey is one of the most products has been used as an antimicrobial agent since the ancient times. The potential antimicrobial activity of honey is arise from its physiochemical proprieties such as high osmotic pressure, low pH, in addition to other factors and enzymes that work as antimicrobial agents. All these components and characteristics of honey led to consider it as one of the most efficient, useful and natural antimicrobial agents. From this point of view, recent study aim to evaluate the antibacterial activity of bee honey on some common species of pathogenic bacteria. The study included some of both gram-positive (Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus spp.) and gram-negative bacteria
(Escherichia coli, Klebsiella pneunoniae, and Pseudomonas aeruginosa). The antibacterial action of honey in three different concentrations (100%, 70% and 50%) was assessed. The results found that honey has the similar antibacterial effect as antibiotics effect. Additionally, the concentration of 100% was the most effective
concentration in the inhibition of bacterial growth, and this concentration gave the best result of antibacterial effect. Furthermore, the results showed that as the concentration of honey decreased the effect of inhibition decrease as well. Finally, the study established that there is no significant different between the gram-positive
and the gram-negative bacteria in the term of inhibition activity.
The current study deals with estimating the protein concentration and the effect of fish weight on protein concentration values in red and white muscles in two different regions ( R1 : Anterior region lies 2 cm behind the head and R2: posterior region lies 2cm from caudal fin (in two types of bony fish, namely common carp (Cyprinus carpio) and Nile tilapia (Oreochromis niloticus). Samples were collected from Karmat Ali river- north of Basrah between October 2019 and February 2020. The protein was extracted using protein extraction buffer, the current study show that the average of protein concentration in red muscles of Nile tilapia ranged between 7.74-7.4 mg / ml and ( 6.8-8.85 mg / ml) in R1 and R2 region re

Keys for 22 species representing ten genera Thripidae collection carried out during 1999-2001 in different localities in the middle of Iraq. Of them four species are described as new to science, Frankliniella megacephala sp. nov; Retithrips bagdadensis sp. nov; Chirothrips imperatus sp. nov; Taeniothrips tigridis sp. nov; Another thirteen species are recorded for the first time in Iraq; Thrips meridionalis (Pri.); Microcephalothrips abdominils (Crawford); Scolothrips pallidus (Beach); Scritothrips mangiferae Pri.; Frankliniella tritici Bagnall; Frankliniella schultzie Trybom; Frankliniella unicolor Morgan; Retithrips aegypticus Mar

Valerio 1929 and H. tringae n. sp. A detailed description of the new taxon is presented along
with a comparison of the diagnostic measurements between the two species.
Thirty individuals of Bellamya bengalensis and Physella acuta were collected and identified from the Tigris River in Baghdad during the period between October to November 2017. The efficiency of bioaccumulation of the two species as bioindicators for aquatic heavy metal pollution with Cd, Ni, Pb and Cu was investigated. Both snail species had the ability to accumulate heavy metals. The mean of Ni concentration in soft tissues of both snails was 1.53 ppm while the mean concentration of other heavy metals was significantly lower; they reached 0.51 ppm, 0.36 ppm and 0.29 ppm, respectively. While no significant differences between B. bengalensis and P.acuta were noticed in th

For the first time in Iraq, the crustacean Ergasilus ogawai Kabata,
1992 was recorded from the gills of Silurus triostegus, Mastacembelus mastacembelus, Mystus pelusius and Acanthopagrus latus out of 12 fish species caught from Garmat Ali river north of Basrah city during the period from September 1999 till August 2000. The percentage incidence of infestations of these four fish species were 98.9%, 100%,
49.6% and 71.4% while the intensity of infestations were 417, 81.8,
3.4 and 2, respectively. No significant differences in infestations of
male and female hosts with this crustacean were detected.
Background: One of the most dominant bacterial infections is urinary tract infection (UTI), both in the community and in the hospital settings Since drug resistance become one of the predominant problems of health worldwide, it is necessary to use new methods to overcome drug-resistant bacteria. In this regard, medicinal plants (Medicago sativa ) are considered one of the richest sources to produce antibiotics.
Aim of the study: evaluate the antibacterial effect of the fraction of ethyl acetate of Medicago Sativa extract against Escherichia Coli isolated from urine samples of patients with urinary tract infections.

Pseudomonas aerogenosa lipopolysaccharidewas extracted by hot phenol method and purified by gel filtration method using the Sephadex G-200 gel and detected by the limulus amebocyt lysate (EU/ml 0.03)(Wako Chemicals USA, Inc.). The inhibitory effect of partially purified LPS on Candida glabrata yeast was studied in a microdilution method. This study found that LPS has an inhibitory effect on Candida glabrata with the lower concentrations. The inhibitory effect of LPS which treated with heating was studied under boiling and wet heat effect. The toxicity of LPS on Candida glabrata was not affected when treated with heating LPS and the results were similar to those found in untreated LPS

Ninety five samples were collected from different samples (urine, ear and wounds swaps), from hospitals in Baghdad city. The results of cultural, microscopic , biochemical tests indicated that in urine samples E.coli have high occurrence frequency 19 (47.5%) followed by Proteus mirabilis 18(45%) and Klebsiella species 1 (2.5%), while in wounds samples each of Pseudomonas spp. and Proteus mirabilis 10 (25%) , then followed by E.coli with 5 (12.5%) and Klebsiella species 3 (7.5%). Ear swaps samples revealed that Pseudomonas aeruginosa 7 (46%) was the major bacterium followed by Proteus mirabilis 4(26.6).Sensitivity test against eleven antimicrobial agents was done for all of the Proteus mirabilis isolates (32 isolates). The results display
