However, comparative genomics revealed that proteins’ length may be affected by additional factors. In 2002 it was shown that in bacterium Escherichia coli and the archaeon Archaeoglobus fulgidus, protein sequences with no homologs are, on average, shorter than those with homologs [1]. Most experts now agree that the length distributions are distinctly different between protein sequences with and without homologs in bacterial and archaeal genomes. In this study, we examine this postulate by a comprehensive analysis of all annotated prokaryotic genomes and focusing on certain exceptions.

  • The Mysterious Orphans of Mycoplasmataceae Tatiana V
    Tatarinova et al. Biology Direct (2016) 11:2 DOI 10.1186/s13062-015-0104-3 RESEARCH Open Access The mysterious orphans of Mycoplasmataceae Tatiana V. Tatarinova1,2*, Inna Lysnyansky3, Yuri V. Nikolsky4,5,6 and Alexander Bolshoy7* Abstract Background: The length of a protein sequence is largely determined by its function. In certain species, it may be also affected by additional factors, such as growth temperature or acidity. In 2002, it was shown that in the bacterium Escherichia coli and in the archaeon Archaeoglobus fulgidus, protein sequences with no homologs were, on average, shorter than those with homologs (BMC Evol Biol 2:20, 2002). It is now generally accepted that in bacterial and archaeal genomes the distributions of protein length are different between sequences with and without homologs. In this study, we examine this postulate by conducting a comprehensive analysis of all annotated prokaryotic genomes and by focusing on certain exceptions. Results: We compared the distribution of lengths of “having homologs proteins” (HHPs) and “non-having homologs proteins” (orphans or ORFans) in all currently completely sequenced and COG-annotated prokaryotic genomes. As expected, the HHPs and ORFans have strikingly different length distributions in almost all genomes. As previously established, the HHPs, indeed are, on average, longer than the ORFans, and the length distributions for the ORFans have a relatively narrow peak, in contrast to the HHPs, whose lengths spread over a wider range of values. However, about thirty genomes do not obey these rules. Practically all genomes of Mycoplasma and Ureaplasma have atypical ORFans distributions, with the mean lengths of ORFan larger than the mean lengths of HHPs.

  • Identification of Anaplasma Phagocytophilum on the Basis of a Fragment of the 16S Rdna Gene*
    Folia biologica (Kraków), vol. 53 (2005), No 3-4 Identification of Anaplasma phagocytophilum on the Basis of a Fragment of the 16S rDNA Gene* Anna RYMASZEWSKA Accepted September 6, 2005 RYMASZEWSKA A. 2005. Identification of Anaplasma phagocytophilum on the basis of a fragment of the 16S rDNA gene. Folia biol. (Kraków) 53: 199-203. Anaplasma phagocytophilum is a bacterial parasite of human and animal granulocytes. Instances of granulocytic anaplasmosis (formerely HGE – human granulocytic ehrlichiosis) have been noted in Europe, including northeastern Poland. Here the results of studies on the occurrence of Anaplasma pathogens in ticks Ixodes ricinus in Western Pomerania are presented. 4,6% of the tick population was infected. Sequence analysis of the 16S rDNA gene, necessary for the classification of the bacteria, revealed that the pathogens were A. phagocytophilum, causing disease in people and domestic animals. The DNA sequences were identical to the sequence considered as a prototype for human granulocytic anaplasmosis (U02521, USA). A neighbor-joining tree was constructed using the A. phagocytophilum sequence (AY303572) from Western Pomerania and 10 sequences from the Ehrlichiae and Anaplasmataceae families downloaded from GenBank. The AY303572 sequence clusters with other pathogenic species found in Europe and the USA. Key words: Anaplasma phagocytophilum, Ixodes ricinus, phylogenetic relationships of Anaplasma phagocytophilum.

Borreliosis And Human Granulocytic Anaplasmosis Coinfection With Positive Rheumatoid Factor And Monospot Test: Case-Report. The Internet Journal of Infectious Diseases. 2006 Volume 6 Number 1. Abstract We are reporting a case of co-infection with B.burgdorferi and A.phagocytophila with unusual clinical and lab results. A 36-year-old Caucasian man from Warner Robins, GA, an engineer, presented with a two-week history of febrile illness up to 103 F, severe headaches, fear of light, body aches, irritability, weakness and night sweats. This started two weeks after a 5- days trip to Panama City, Florida, where he had to work outdoors. Physical exam yielded no specific signs. Ultrasound showed hepatomegaly. Laboratory studies revealed elevated liver enzymes, B.burgdorferi IgM 3.7 index, A.phagocytophila IgM ≥1:1280, rheumatoid factor, atypical lymphocytes and positive monospot test. Patients who have been diagnosed with one tick-borne infection are at an increased risk and should be tested for other related infections. Rheumatoid factor and monospot test may be falsely positive in such cases.

Tufts,1, Max McClure, and Maria A. Diuk-Wasser Department of Ecology, Evolution, and Environmental Biology, Columbia University, 1200 Amsterdam Avenue, New York, NY 10027, and 1Corresponding author, e-mail: [email protected] Subject Editor: Sarah Hamer Received 12 November 2019; Editorial decision 3 October 2020 Abstract The blacklegged tick (Ixodes scapularis Say) is the primary vector of Borrelia burgdorferi sensu stricto (Spirochaetales: Spirochaetaceae), the Lyme disease agent in North America. The basic reproduction number (R0) for B. burgdorferi in I. scapularis in the Northeast is highly sensitive to the probability that engorged larvae survive the winter, molt into nymphs, and find a host. These processes are dependent on local environmental variables, including climate, host population size and movement, and tick behavior. A simple model is presented for estimating host-finding success from the ratio of tick abundance in two subsequent years, accounting for overwinter survival and possible differences in host associations between nymphs and larvae. This model was parameterized using data from two sites in mainland Connecticut and two on Block Island, RI. Host abundance and tick burdens were estimated via mark–recapture trapping of the primary host, Peromyscus leucopus Rafinesque. Overwintering survival was es- timated using engorged larvae placed in field enclosures at each site.

  • Canine Vector-Borne Diseases in India Is Limited
    Megat Abd Rani et al. Parasites & Vectors 2010, 3:28 http://www.parasitesandvectors.com/content/3/1/28 REVIEW Open Access CanineReview vector-borne diseases in India: a review of the literature and identification of existing knowledge gaps Puteri Azaziah Megat Abd Rani*1, Peter J Irwin2, Mukulesh Gatne3, Glen T Coleman1 and RebeccaJTraub1 Abstract Despite the combination of favourable climate for parasites and vectors, and large populations of stray dogs, information concerning the epidemiology, diagnosis and management of canine vector-borne diseases in India is limited. However, with the country's expanding economy and adaptation to western culture, higher expectations and demands are being placed on veterinary surgeons for improved knowledge of diseases and control. This review aims to provide an overview of the current state of knowledge of these diseases in India and identify existing knowledge gaps in the literature which need to be addressed. The available literature on this subject, although limited, suggests that a number of canine vector-borne diseases such as filariasis, babesiosis and ehrlichiosis are endemic throughout India, as diagnosed mostly by morphological methods. Detailed investigations of the epidemiology and zoonotic potential of these pathogens has been neglected. Further study is essential to develop a better understanding of the diversity of canine vector-borne diseases in India, and their significance for veterinary and public health. Review domesticated dog [3]. Despite this, information available India has a wide range of climatic zones, from montane to veterinarians concerning the prevalence, epidemiol- (cold, wet alpine) and semi-arid regions to the wet trop- ogy, diagnosis and management of canine vector-borne ics, which make it suitable for a diverse range of vectors diseases (CVBD) and those of zoonotic concern is scarce and pathogens of medical and veterinary importance, [4].
