A culture of the cellulolytic bacterial organism, Sporocytophaga myxococcoides (A.T.C.C. No. 10010), has been studied. In or on media containing cellulose, the primary effective cells are long and acuminate; in old cultures a large proportion of them become spherical or spheroid and are bound together in mucilage, in which new spheroid cells develop. In or on media containing cellobiose, glucose, or mannose as the source of carbon, the primary effective cells resemble those on cellulose media, but the resting cell is a spherical granule, its diameter not more than twice the width of the acuminate cell; the spheroid cells do not become aggregated in the mucilage, and do not physically resemble the so-called microcysts except in shape.

Much recent attention has been focused on vegetative survival forms of planktonic diatoms and other algae. There are several reports of extended vegetative survival of the freshwater diatom Melosira in lake sediments. In contrast to those diatoms which form a morphologically distinct resistant spore, Melosira is known to produce physiological resting cells that are indistinguishable in outward morphology from actively growing cells.We used both light and electron microscopy to document and elucidate the sequence of cytological changes during the transition from resting cells to actively growing cells in a population of Melosira granulata from Douglas Lake, Michigan sediments collected in mid-July of 1983.

The aim of the present study was to characterize the antibiotic resistance profile of enterobacteriaceae strains isolated in Infectious Diseases Hospital Galati, Romania, during 2016, in order to guide the local antibiotic stewardship strategy. There are 597 biological samples with positive cultures for enterobacteriaceae, related to invasive and non-invasive infections. The main bacterial genus were E. coli 62%, Klebsiella spp 15%, Proteus spp 11% and Salmonella spp 6%. Over a half of isolated strains have one or more antibiotic resistance. The resistance level depends on bacterial genus, with highest level found among the rare isolates: Enterobacter spp, Citrobacter spp, Morganella spp and Serratia spp. The rate of MDR was 17.,6% for E. coli, 40.9% for Klebsiella spp and 50.7% for Proteus spp. while the rate of strains producing Extended Spectrum of Beta Lactamase are 7.2% for E. coli, 28.4% for Klebsiella spp and 12.3% for Proteus spp. The carbapenem resistant strains were found in 1.1% cases.

Abstract Nigella A, also named Sieboldianoside A, has been extracted from many kinds of Traditional Chinese Medicine (TCM), such as Nigella glandulifera, Stauntonia chinensis DC., and the leaves of Acanthopanax sieboldianus. Nigella A exhibited potential analgesic, anti-inflammatory, anti-tumor, and antioxidant activities. However, whether Nigella A could treat ulcerative colitis (UC) is still unknown. As saponins always be regarded as the kinds of ingredients that could regulate immunity and intestinal flora. This research aimed to investigate the therapeutic effect of Nigella A on UC and explore its effect on intestinal flora. We noted that Nigella A and Sulfasalazine (SASP) could significantly improve the signs and symptoms, alleviate colonic pathological injury in DSS-induced mice. The changing of many specific bacterial genus such as Lactobacillus, Porphyromonadaceae, Bacteroides and Escherichia might closely related to the recovery of intestinal inflammatory response. This study initially confirmed the therapeutic effect of Nigella A and SASP on DSS-induced colitis by improving the diversity of intestinal microbial composition. Nigella A has the potential to be developed for the treatment of UC and other disorders related to the imbalance of intestinal flora.

ABSTRACT Biodesulfurization was monitored in a recombinant Pseudomonas putida CECT5279 strain. DszB desulfinase activity reached a sharp maximum at the early exponential phase, but it rapidly decreased at later growth phases. A model two-step resting-cell process combining sequentially P. putida cells from the late and early exponential growth phases was designed to significantly increase biodesulfurization.

Abstract Variations in the levels of acute phase proteins and lactoferrin in serum and milk for diagnosis of subclinical mastitis in dairy cows are described in this research paper. Milking animals from two organized dairy farms in Kerala, India, were screened by California Mastitis Test (CMT), Electrical Conductivity test (EC) and Somatic Cell Count (SCC) test to identify animals affected with sub clinical mastitis (SCM). The concentrations of acute phase proteins (APP) Haptoglobin (Hp), C- reactive protein (CRP), Albumin, Lactoferrin (Lf) and α- 1 acid glycoprotein (AGP) in milk and Hp, Albumin, Serum Amyloid A (SAA) and CRP in the serum of 40 normal cows and 40 cows affected with sub clinical mastitis were assessed. Solid phase ELISA was employed for assessment of all parameters except the albumin levels, for which spectrophotometry was used. The values of Hp in milk; and SAA, AGP and Lf in serum, were significantly elevated in the group with sub clinical mastitis. Such variations were found to be independent of the specific bacterial organism causing the disease. These results show that significant variations exist in the levels of acute phase proteins Hp, AGP and Lf in milk, and SAA in serum of animals affected with subclinical bovine mastitis that are not affected by specific bacterial etiology.

The most widespread ailments in dogs are urinary tract infections (UTIs) caused by bacterial species. It is necessary to recognize the prevailing bacterial pathogens and their susceptibility to antimicrobial agents to effectively treat UTIs. The present study aimed to classify the bacterial organism that causes UTIs in dogs and their patterns of antimicrobial resistance. A total of 141 urine samples were collected from diseased dogs in Veterinary Clinical Complex LUVAS in Hisar, India. Culture, biochemical and sensitivity testing were performed for each of the urine samples based on standard method. Of the total 141 urine samples from dogs, 21 (14.9%) isolates were identified as Klebsiella spp. The isolates were found to be highly resistant to ampicillin (100%), penicillin G (100%), oxytetracycline (100%), enrofloxacin (85.7%), chloramphenicol (80.6%), ceftriaxone (76.2%) and cloxacillin (71.4%), while susceptibility was observed against gentamicin (100%), amikacin (100%) and neomycin (90.5%). In the current study, 19 out of 21 identified isolates were found to be multidrug-resistant. This study indicates that dogs in the study area are found to harbor highly resistant Klebsiella spp. Therefore, when deciding on the antibiotic regimen for UTIs cases, Vets should consider resistance profile of chosen antibacterial agents before usage in order to discourage dissemination of resistant organisms in the study area.
