In genetic analysis of bovine Staphylococcus aureus isolates that are recognized as an important pathogenic bacterium in bovine mastitis, multilocus sequence typing (MLST) showed strong correlation to the results of pulsed-field gel electrophoresis, coa PCR-restriction fragment length polymorphism (RFLP), spa typing, and the coagulase serotyping method. According to MLST results, strains derive...
worship is submission and humitility with believe to divinity in fornt of god. in jewish religion ,worship is submission of the god inall the ordes and devosion tohim .worshio is not only so widely in islam and jew and does not include pray and fast and etc but also is every action that human does with divine intention and to content him. worship has huge and excellent rank in qoran and old te...
background : the aim of the present study was to evaluate the effects of metronidazole and albendazole against clinical isolates of giardia lamblia in vitro. methods : from all human samples of containing cysts, 10 isolates were successfully excysted in vitro . trophozites viability was assessed by eosine 0.1% and cultured axenically in tyi-s-33 modified medium supplemented with heat inactivate...
OBJECTIVES To identify the staphylococcal cassette chromosome mec (SCCmec) types of methicillin-resistant Staphylococcus aureus (MRSA) isolated from bovine milk, and examine the genetic relatedness between MRSA from bovine milk and MRSA from human isolates. METHODS Antimicrobial susceptibility tests were performed on MRSA isolated from bovine milk. PCR and sequencing analysis were performed t...
the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...
coagulase-negative staphylococci (cons) are often associated with bovine mastitis and may be resistant to antimicrobial therapy. the aim of the current study was to investigate the presence of blaz (responsible for penicillin resistance) and meca (responsible for methicillin resistance) genes among 108 cons belonging to 9 different species isolated from bovine mastitis in seven dairy herds (h1-...
The objectives of this study were to examine the diversity of Staphylococcus spp. recovered from bovine intramammary infections and humans working in close contact with the animals and to evaluate the susceptibility of the staphylococcal isolates to different antimicrobials. A total of 3,387 milk samples and 79 human nasal swabs were collected from 13 sampling sites in the KwaZulu-Natal provinc...
Background: Cryptosporidiosis is prevalent in animals and human beings, both immuno-competent and immuno-compromised persons, worldwide. Epidemiologically, it is important to differentiate between human and animal species. The aim of this study is to define the utility of a 1055 bp fragment of 18s rRNA for differentiation of Human and Cattle Cryptosporidiosis. Material and methods: 1020 human...
stx(2) genes from 138 Shiga toxin-producing Escherichia coli (STEC) isolates, of which 127 were of bovine origin (58 serotypes) and 11 of human origin (one serotype; O113:H21), were subtyped. The bovine STEC isolates from Australian cattle carried ehxA and/or eaeA and predominantly possessed stx(2-EDL933) (103 of 127; 81.1%) either in combination with stx(2vhb) (32 of 127; 25.2%) or on its own ...
Campylobacter jejuni isolates of different origins (bovine, broiler meat, human) were screened by polymerase chain reaction for the presence of 4 genes cdtB, cst-II, ggt, and virB11, previously linked to virulence such as adherence, invasion, colonization, molecular mimicry, and cytotoxin production. In addition, the isolates were screened for the presence of the global gene regulator csrA link...
