Biofilm Shows Independency from Hemolysin Genes Arsenal in Methicillin Resistant Staphylococcus aureus.
...Show More Authors

Normally, bacteria exposed to antibiotics at sub minimal inhibitory concentrations (MIC) inside the host. Therefore, the current study aimed to comprehend the association among hemolysins, biofilm, as well as gentamicin resistance in local MRSA isolates. Around 35 Staphylococcus aureus locally isolated from different clinical specimens were employed in this study. Methicillin resistance was detected via cefoxitin disk diffusion and mecA amplification methods. MIC of gentamicin was estimated by broth microdilution method. Hemolysin genes involving hla, hlb, hld, and hlg were determined using multiplex polymerase chain reaction (PCR) technique. Microtiter plate method was employed for biofilm assessment in the presence and absence of gentamicin at sub MIC. Moreover, atomic force microscopy technique was employed for confirming the effect of gentamicin on biofilm. The present findings revealed that methicillin resistant S. aureus (MRSA) constituted, nearly, 94.29% (33 isolates) of all S. aureus isolates. Around 12 (36.36%), four (12.12%), and 17 (51.51%) isolates were gentamicin-sensitive, intermediate, and resistant to gentamicin, respectively. hla and hld were located in 32 out 33 MRSA isolates. All MRSA isolates succeeded in forming biofilm; however, three (0.09%), 23 (69.69%), and seven (21.21%) isolates formed weak,moderate, andstrong biofilm, respectively. Gentamicin at sub MIC reduced the intensity of biofilm and the AFM confirmed this finding. In conclusion, very weak correlation linked the biofilm formation capacity and isolate MIC. On the other hand, possession of hemolysin genes seems has no correlation with biofilm formation. Nevertheless, gentamicin at sub MIC reduced the intensity of MRSA biofilm.

IDENTIFICATION OF HARD TICKS FROM BUFFALO BUBALUS BUBALIS (LINNAEUS, 1758) IN IRAQ
...Show More Authors

Ticks (Acari: Ixodidae) are ectoparasites that infest livestock in every geographic region of the world and are vectors of several viral, bacterial, and protozoan pathogens to both animals and humans. There is little information is available is about tick presence in Buffalo Bubalus bubalis (Linnaeus, 1758) (Artiodactyla, Bovidae) in Iraq. The current study determined the species of ticks parasitizing Buffalo in some central and southern regions included: Baghdad (Al Fathelia), Karbala (Al-Hussainia), Wasit (Kut and Al-Suwairah), Al-Qadisia (Al- Diwaniyah, Al- Saniya, Al-Mihnawea, and Afak), Thi Qar (Al-Nasiriyah and Al-chibayish), Missan (Amara and Qalaat Salih) and Basrah (Al-Haretha, Al-Madena and Al-Deer). A total of 150 Buffal

Smart Management for Secondary School Principals in Education Directorates from Their Viewpoint
...Show More Authors

The research aimed to identify smart management capabilities of secondary school principals in education directorates in Baghdad according to the administrative intelligent and leadership competencies. The study used incentives as a descriptive method, by analyzing five main areas of smart management: strategic planning, self-awareness, skills, organization and culture. A purposive sample consisting of 102 secondary school principals from education directorates (Rusafa1) and (Karkh2), was taken to fill questionnaire the latter representing a complete sample of the target population. validated has been built an advanced measurement tool composed of 56 items across the five domains of strategic planning (21%), self-awareness (21%), culture (2

Prevalence of Pathogenic Bacteria from Contaminated Yemeni Currency Notes in Taiz City
...Show More Authors

ABSTRACT: Pathogenic bacteria responsible for the causation of many common diseases have been identified on currency notes. The present investigation was carried out on one hundred currency notes of all the denominations (50, 100, 250, 500 and 1000RY), obtained from different occupational mainly bus drivers, hawker street, vegetable vendor, restaurants and butchers and fish seller groups in Taiz city,Yemen. Identification and characterization revealed active participation of the following species of organisms in the ascending order of percentage as E. coli(50.28 %),Staphylococci aureus(14.04 %), Klebsiellaspp(4.39 %),proteus(4.39 %), salmonella(1.25 %), shigella(0.72 %), Coagulase negative staphylococcus(0.60 %), pseudomonas(0.50 %),

Detection and isolation of flavonoids from Calendula officinalis (F.Asteraceae) cultivated in Iraq
...Show More Authors

Calendula officinalis L. (Asteraceae) known as marigold is known to have several pharmacological activities and used for the treatment of several diseases as measles, jaundice, constipation and several inflammations. Marigold flowers contain several chemical constituents mainly flavonoids, triterpenoids and essential oil. In this study marigold flowers cultivated in Iraq had been investigated for its flavonoids content. The study revealed the presence of quercetin and kaempferol glycosides and the absence of myricetin glycosides. The flowers were extracted with ethanol 70% fractionated with different solvent and the flavonoids were isolated by preparative HPLC. The isolated flavonoids were identified by measuring melting points, UV, IR,

From Friendship to Fracture: The Role of Place in Lynn Nottage’s Sweat
...Show More Authors

Human relationships are shaped and affected by the place they live in. This article analyzes Lynn Nottage’s Sweat from the perspective of spatial theory, particularly using the theories of Yi-Fu Tuan and Doreen Massey, to explore the complex connection between place and human relationships. The article examines how Nottage presents the reciprocal effect between people and their setting. By examining the city, the factory, and the local community around it, the study shows how place serves as a dynamic force that shapes the characters’ identities and relationships rather than just serving as a background. While Massey’s concept of place as a product of social relations offers a framework to explore the tensions and solidarity that aris
