Abstract
Shigella spp. are water-borne pathogens responsible for mild to severe cases bacilli dysentery all around the world known as Shigellosis. The progressively increasing of antibiotic resistance among Shigella calls for developing and establishing novel alternative therapeutic methods. The present study aimed to evaluate a novel phage cocktail of lytic phages against extended spectrum beta lactamase isolates of Shigella species in an aquatic environment. The phage cocktail containing six novel Shigella specific phages showed a broad host spectrum. The cocktail was very stable in aquatic environment. The cocktail resulted in about 99% decrease in the bacterial counts in the contaminated water by several species and strains of Shigella such as Shigella sonnei, Shigella flexneri and Shigella dysenteriae. Achieving such a high efficiency in this in-vitro study demonstrates a high potential for in-vivo and in-situ application of this phage cocktail as a bio-controlling agent against Shigella spp. contamination and infections.

Abstract
A new actinobacterial strain was isolated from Ab-e-Siah spring (dark water) taken from the Ramsar city in Iran, and subjected to several stress conditions investigation. The isolate, named MG2 strain, was Gram-positive, aerobic, diplococci or tetrad shaped, non-spore forming and non-motile. Phylogenetic analysis of the isolate using 16S rDNA sequence indicated that the organism matched best with the genus Kocuria and the highest sequence similarities (98.55%) being found with Kocuria rosea. The 16S rDNA sequence determined in this study has been deposited in the NCBI database with the accession no. JX534199, K. rosea strain MG2. The isolated strain was an alkaliphilic-mesophilic bacterium because the optimal growth was observed at pH 9.2 and temperature of 28 °C under aerobic condition. MG2 was a halotolerant strain and tolerated maximally to 15% NaCl concentraion. Viability analysis by flow cytometry indicated that this strain had highly resistance to UV-C radiation and moderately resistance to desiccation after 28 days. The viability of K. rosea strains MG2 and Deinococcus radiodurans R1 were determined D87 and D98 according to D index, respectively, by a dose radiation 25 J/cm (Appukuttan et al., 2006). Thus the UV resistance of strain MG2 was comparable with representative radiation resistant Deinococcus. Also MG2 was grown at 1-4% of H2O2 as an oxidant agent. This research is the first study on multiple extreme resistance of Kocuria rosea new strain (MG2) isolated in Iran.

Abstract
Although the infection of different animals and non-human primates with other members of Anelloviridae have already been reported there is no report about infection of animals with Torque teno midi virus/Small anellovirs (TTMDV/SAV). The aim of this study was to detect the virus in domestic village chickens. Blood samples were collected from 79 domestic village chickens in Isfahan. Blood samples of five adult laying hens and one cockerel were collected in three consecutive weeks (days 1, 8 and 14) as experimental chickens. Ten eggs were randomly collected from the eggs laid during days 12 to 17 and thin and thick egg whites and yolk samples were collected aseptically. After DNA extraction Nested-PCR was performed using SMAs/SMAr primers. In PCR, 431 bp and 441 bp products were detected. The detected bands were extracted and sequenced. Totally 26 out of 79 (32.9%) of the blood samples were positive for the virus. The frequency of the infection of the different parts of the eggs tested was 76%. For the first time TTMDV/SAV was detected in domestic village chickens which also vertically transmitted to eggs.
