In this work, three isolates of Plasmodium juxtanucleare have been analyzed based on morphological, morphometric and parasitic parameters. Each isolate was sampled from naturally infected adult chicken (Gallus gallus) from rural areas of three Brazilian municipalities: Seropédica (22 degrees 48' S; 43 degrees 41' W), in the state of Rio de Janeiro; Cruzeiro (22 degrees 33' S; 44 degrees 57' W),...

A set of forty-nine Lactobacillus isolates recovered from the faecal swabs of different dog breeds viz. Pomeranian (12), Labrador (15) and mongrel/indigenous dogs (22) were subjected to Lactobacillus group-specific multiplex PCR corresponding to the 16S-23S rRNA intergenic spacer region (ISR) and its flanking 23S rRNA gene. Twenty-three (46.9%) isolates were found to be positive for Group IV; s...

Twelve Korean infectious bronchitis viruses (IBVs) were isolated in the field from chickens suspected of being carriers of infectious bronchitis between 2001 and 2003. The S1 glycoprotein genes of these IBV isolates were amplified by reverse transcriptase-polymerase chain reaction (RTPCR) and analyzed by restriction fragment length polymorphism (RFLP) analysis. These Korean IBV isolates were cl...

The majority of the keratitis-causing Acanthamoeba isolates are genotype T4. In an attempt to determine whether predominance of T4 isolates in Acanthamoeba keratitis is due to greater virulence or greater prevalence of this genotype, Acanthamoeba genotypes were determined for 13 keratitis isolates and 12 environmental isolates from Iran. Among 13 clinical isolates, eight (61.5%) belonged to T4,...

Taiwanese isolates of Phytophthora infestans were examined for mating types and pathogenicity to tomato and potato. A total of 70 isolates, including 68 isolates from tomato and 2 isolates from potato, from six counties of Taiwan were all A1 mating type. Three tomato isolates of P. infestans caused only leaf blight of tomato, while two isolates obtained from potato were able to cause the diseas...

Yellow starthistle (Centaurea solstitialis L.) (YST) is an important invasive plant that infests millions of hectares in the western USA and Canada. Isolates of the exotic rust fungus Puccinia jaceae have been evaluated as a potential biological control for YST. The objectives of this study were to characterize isolates of P. jaceae by amplified fragment length polymorphic (AFLP) DNA analysis a...

Three feline virus isolates were shown to be members of the reovirus group by their growth characteristics in cell cultures, physicochemical properties, and appearance under an electron microscope. Their close serological relationship to, or identity with, human reovirus type III was revealed by hemagglutination, hemagglutination inhibition, serum neutralization, and gel diffusion tests. One fe...

Thermophilic campylobacters were isolated from three sewage plants in Rio de Janeiro, RJ, Brazil and identified. Laboratory analysis of 390 sewage samples showed the presence of 169 thermophilic strains. The results demonstrated that human and animal pathogenic biotypes could be isolated from activated sludge during the initial processing steps. The aeration tank could be considered a barrier t...

We report the draft genome sequences of three enteropathogenic Escherichia coli (EPEC) isolates that display the O157 serogroup but do not have the Shiga toxin genes (stx), which are characteristic of O157 enterohemorrhagic E. coli (EHEC). E. coli strain RN587/1 has the O157:H8 serotype and possesses the EAF plasmid characteristic of typical EPEC (J. B. Kaper, J. P. Nataro, and H. L. Mobley, Na...

Three glutamic-acid-producing coryneform strains were isolated from soil and vegetable samples. Chemotaxonomic investigations indicated that these strains belonged to the genus Corynebacterium. Phylogenetic studies, based on 16S rDNA analysis, demonstrated that the three strains formed a distinct cluster within the genus Corynebacterium and that their nearest relatives were Corynebacterium glut...
