Interpretation of doxycycline+chloroquine dual therapy for A. phagocytophilum infection in dogs
ABSTRACTObjective. A. phagocytophilum, an obligate intracellular pathogen, is a well-known agent causing granulocytic infections in both animals and humans. The purpose of the present study was to describe clinical course and consequences of Canine Granulocyctic Anaplasmosis among dogs in Aydin province, Turkey with special reference to hematological alterations and possible interpretations of doxycycline+chloroquine dual therapy. Materials and methods. A controlled clinical trial was carried out on 14 dogs referred and diagnosed as Canine Granulocyctic Anaplasmosis within Snap 4dx test. Relevant haematological data were recorded before (day 0) and after treatment (day 30) in both groups. Group I (n=7) were adminestered doxycycline (10 mg/kg q 12 h via oral route for 14 days) and chloroquine (2.5 mg/kg q 12 h for 14 days) and group II (n=7) received only doxycycline (10 mg/kg q 12 h for 14 days via oral route) therapy. Results. Doxycycline treatment hasten resolution of clinical signs in all dogs in about 2 to 7 days. There was no statistically significant differences among hematological variances detected (p>0.05). Conclusions. It may suggest that in conjunction with doxycycline chloroquine may have helped to speed up relevant clinical signs of CGA.RESUMENObjetivo. A. phagocytophilum, un patógeno intracelular obligado, es un agente ampliamente conocido que causa infecciones granulocíticas tanto en animales como en humanos. El propósito del presente estudio fue describir la evolución clínica y las consecuencias de la Anaplasmosis Granulocítica Canina en perros de la provincia de Aydin, Turquía, con especial referencia a las alteraciones hematológicas y a las posibles interpretaciones de una terapia dual de doxicilina+cloroquina. Materiales y métodos. Se realizó un estudio clínico controlado en 14 perros remitidos y diagnosticados con Anaplasmosis Granulocítica Canina usando de una prueba Snap 4dx. Se registraron datos hematológicos pertinentes antes (día 0) y después del tratamiento (día 30) en ambos grupos. Al Grupo I (n=7) se le administró doxicilina (10 mg/kg q 12 h por vía oral durante 14 días) y cloroquina (2.5 mg/kg q 12 h durante 14 días), mientras que el Grupo II (n=7) recibió una terapia únicamente con doxicilina (10 mg/kg q 12 h por vía oral durante 14 días). Resultados. La doxicilina aceleró la resolución de los signos clínicos en todos los perros en un periodo de aproximadamente 2 a 7 días. No se detectaron diferencias estadísticas significativas entre las variaciones hematológicas (p>0.05). Conclusiones. Lo anterior puede sugerir que, conjuntamente con la doxicilina, la cloroquina puede haber ayudado a acelerar los signos clínicos pertinentes de la Anaplasmosis Granulocítica Canina (AGC).
Babesia and Human Babesiosis
Babesiosis, caused by tick-transmitted intraerythrocytic parasites (Babesia spp.), occurs worldwide. The disease mainly affects livestock, but records of infections in humans are increasing, and the disease is considered to be emerging worldwide. This book provides a comprehensive and holistic view of Babesia species that can infect humans. Numerous experts analyze, in detail, basic aspects of the biology of Babesia, the pathology of the babesiosis highlighting the pathogenesis of babesiosis in sickle cell, the eco-epidemiology of tick vectors and the impact of climate change on them, the current status, and future prospects for laboratory diagnosis and measures to prevent transfusion transmission. The book also focused on unidentified Babesia parasites that continue to emerge, most likely from wildlife, for which neither tick vector species nor vertebrate reservoir host species are currently known. Lastly, current and new therapies for infected patients, in vitro and in vivo culture systems for antibabesial evaluation and measures to prevent infections are also considered

Authors\u27 Description:
Microbiology for Allied Health Students is designed to cover the scope and sequence requirements for the single semester Microbiology course for non-majors and allied health students. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of Microbiology for Allied Health Students make the material interesting and accessible to students while maintaining the career-application focus and scientific rigor inherent in the subject matter.
The scope and sequence of Microbiology for Allied Health Students has been developed and vetted with input from numerous instructors at institutions across the U.S. It is designed to meet the needs of most microbiology courses allied health students.
With these objectives in mind, the content of this textbook has been arranged in a logical progression from fundamental to more advanced concepts. The opening chapters present an overview of the discipline, with individual chapters focusing on cellular biology as well as each of the different types of microorganisms and the various means by which we can control and combat microbial growth. The focus turns to microbial pathogenicity, emphasizing how interactions between microbes and the human immune system contribute to human health and disease. The last several chapters of the text provide a survey of medical microbiology, presenting the characteristics of microbial diseases organized by body system.

Ultrasensitive detection of toxocara canis excretory-secretory antigens by a nanobody electrochemical magnetosensor assay.
peer reviewedHuman Toxocariasis (HT) is a zoonotic disease caused by the migration
of the larval stage of the roundworm Toxocara canis in the human host.
Despite of being the most cosmopolitan helminthiasis worldwide, its
diagnosis is elusive. Currently, the detection of specific immunoglobulins
IgG against the Toxocara Excretory-Secretory Antigens (TES), combined
with clinical and epidemiological criteria is the only strategy to diagnose
HT. Cross-reactivity with other parasites and the inability to distinguish
between past and active infections are the main limitations of this
approach. Here, we present a sensitive and specific novel strategy to
detect and quantify TES, aiming to identify active cases of HT. High
specificity is achieved by making use of nanobodies (Nbs), recombinant
single variable domain antibodies obtained from camelids, that due to
their small molecular size (15kDa) can recognize hidden epitopes not
accessible to conventional antibodies. High sensitivity is attained by the
design of an electrochemical magnetosensor with an amperometric readout
with all components of the assay mixed in one single step. Through
this strategy, 10-fold higher sensitivity than a conventional sandwich
ELISA was achieved. The assay reached a limit of detection of 2 and15
pg/ml in PBST20 0.05% or serum, spiked with TES, respectively. These
limits of detection are sufficient to detect clinically relevant toxocaral
infections. Furthermore, our nanobodies showed no cross-reactivity
with antigens from Ascaris lumbricoides or Ascaris suum. This is to our
knowledge, the most sensitive method to detect and quantify TES so far,
and has great potential to significantly improve diagnosis of HT. Moreover,
the characteristics of our electrochemical assay are promising for the
development of point of care diagnostic systems using nanobodies as a
versatile and innovative alternative to antibodies. The next step will be the
validation of the assay in clinical and epidemiological contexts
