Multi-drug resistant Klebsiella pneumoniae causing urinary tract infections in children in Pakistan
Multi-drug resistant (MDR) Klebsiella pneumoniae has been associated with different types of infections and the most important aspect is the emergence of MDR strains particularly in hospitalized children. They have the proficiency to cause bacteremia, septicemia and urinary tract infections (UTI). The objective of this study was to determine the susceptibility of MDR K. pneumoniae causing UTI in children. One thousand...

Activity of conessine at various temperatures and pH on inhibition of germination of Bacillus cereus and Bacillus stearothermophilus spores
This work reports the activity (at various conditions) of conessine isolated from methanolic extract of Holarrhena floribunda, on the inhibition of the germination of two Bacillus spores species. This activity was studied by treating spores of Bacillus cereus T and Bacillus stearothermophilus CNCH 5781 with effective concentrations of conessine at various temperature, pH and treatment times. The inhibition of...

Antimicrobial susceptibility patterns of community-acquired Gram-negative uropathogens
Drug resistance is now a public health crisis and global problem. This study was performed to identify the antibiotic susceptibility of urinary tract infections (UTI) in Sanqar City of Kermanshah, Iran. Urine specimens of 891 ambulatory patients over 18 years of age with clinically suspected UTI were referred from Physicians' Office (MD) to the Sanqar Hospital (Kermanshah, Iran) for urine culture from September 1,...

Affectivity of Spodoptera littoralis nucleopolyhedrovirus (SpliNPV) against first and second instar larvae of the cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae)
Preliminary bioassays were conducted to determine the virus activity against the 1st and 2nd instar larvae of the cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae). First instar larvae were more susceptible to the virus than the second instar larvae. Mortality response of the larvae was greater at the highest concentration of the virus than at lowest concentrations. The lethal concentration that...

In-vitro efficacy of polymyxin B with rifampin, colistin and doxycycline against extensively drug resistant Acinetobacter baumannii
Acinetobacter baumannii is an opportunistic Gram negative coccobacillus that can grow easily in moist as well as dry conditions. During the last decade, A. baumannii emerged as one of the most resistant opportunistic pathogens responsible for nosocomial infections including ventilator associated pneumonia. The bug remains an important and difficult to treat pathogen whose pan-drug resistant nature has created a serious...

Production, purification and characterization of cellulase from Streptomyces sp.
High cellulase producing Streptomyces strain C188 was isolated from a Saudi Arabia soil sample and identified as Streptomyces longispororuber by 16S rDNA sequencing. Enzyme productivity by this strain in carboxymethyl cellulase liquid medium reached 8540 U/L after 96 h of incubation at 30°C. Cellulase productivity in tested strain was improved (25084 U/L) by supplementation of the carboxymethyl cellulase liquid...

Prokaryotic biodiversity of halophilic microorganisms isolated from Sehline Sebkha Salt Lake (Tunisia)
North of Tunisia consists of numerous ecosystems including extreme hypersaline environments in which the microbial diversity has been poorly studied. The Sehline Sebkha is an important source of salt for food. Due to its economical importance with regards to its salt value, a microbial survey has been conducted. The purpose of this research was to examine the phenotypic features as well as the physiological and...

Relationship between fungal community and physico-chemical characteristics in the Hokersar Wetland, Kashmir Himalayas
Relative effect of some physico-chemical parameters of water on the occurrence of water borne fungi was studied in a high altitudinal wetland. The number of conidial fungal species was enumerated in water samples collected monthly during the period of March 2008-February 2009. There was marked seasonal fluctuation in the occurrence number of individuals in each species. The maximum number of individuals was found during...

Staphylococcus aureus nasal carriage in centers of Casablanca (Morocco)
The aim of this study was to determine the prevalence of nasal carriage of Staphylococcus aureus among patients and personnel of private centers at Casablanca, and to determine the resistance pattern of isolates. The carriage of virulence toxin genes by the methicillin resistant strains was also investigated. This study was conducted from November 2008 to February 2009. Nasal swabs were taken from 145 and 42 patients...

Comparison of the microbial quality of pork and poultry meat with or without grill marinade available in Polish retail markets
During April and September 2012, a study on pork and poultry meat was undertaken to assess the differences in microbial quality of pork and poultry between the marinated and unmarinated products available in local trade network. Examination of the meats revealed that the vast majority of samples (98.5%) were of satisfactory microbiological quality according to Commission Regulation (EC) No 2073/2005, as amended....

Investigation of Anaplasma phagocytophilum among agrarian residents and domestic animals in Anhui Province, China
A total of 596 blood samples from agrarian residents, and 132 from goats, 12 from dogs and six from cattle were collected from 3 rural Counties including Guangde, Mingguang and Huaiyuan in Anhui Province. The survey questions presumed exposure risk of Anaplasma phagocytophilum were recorded for each participant and statistically analyzed. The antibodies against A. phagocytophilum were determined using an...

Evaluation of the probiotic properties of Bacillus spp. strains isolated from Tunisian hypersaline environments
Bacillus species are ubiquitous and diverse both in the terrestrial and marine ecosystems. In this study, Bacillus species were isolated from Tunisian hypersaline environments and their probiotic properties were studied. In total, 13 strains were identified as a Bacillus spp. Antagonism assay revealed an inhibitory effect of these strains against pathogenic bacteria. Cell surface hydrophobicity values ranged between...
