First detection of Chlamydia avium in healthy Amazon parrots (Amazona aestiva) in Argentina.

In recent years, new Chlamydia species, other than Chlamydia psittaci, have been confirmed in birds. One of these new species, Chlamydia avium, was reported mainly in pigeons and parrots in Europe. Analyzing multimucosal swabs obtained from 7 Amazon parrots (Amazona aestiva) from illegal trade and admitted to the Reserva Experimental Horco Molle (Tucuman, Argentina) for their rehabilitation, we describe the finding of the genetic material of C.

Nocardiosis Associated with Primary Immunodeficiencies (Nocar-DIP): an International Retrospective Study and Literature Review.

Purpose: Nocardiosis is a life-threatening infectious disease. We aimed at describing nocardiosis in patients with primary immunodeficiency diseases (PID).

Methods: This international retrospective cohort included patients with PID and nocardiosis diagnosed and/or published from Jan 1, 2000, to Dec 31, 2016.

Detection and molecular characterization of Chlamydia psittaci and Chlamydia abortus in psittacine pet birds in Buenos Aires province, Argentina.

In order to determine the presence and genetic diversity of Chlamydia spp. in the north-eastern area of Buenos Aires province, Argentina, conjunctival, oropharyngeal, cloacal swab and tissues were collected from a total of 90 psittacine pet birds of different age and clinical manifestations. Through molecular methods, Chlamydiaceae was detected in 30% (27/90) of the samples, out of which 70.

Evaluation of a modified single-enzyme amplified-fragment length polymorphism technique for fingerprinting and differentiating of Mycobacterium kansasii type I isolates.

The usefulness of single-enzyme amplified-fragment length polymorphism (AFLP) analysis for the subtyping of Mycobacterium kansasii type I isolates was evaluated. This simplified technique classified 253 type I strains into 12 distinct clusters. The discriminating power of this technique was high, and the technique easily distinguished between the epidemiologically unrelated control strains and our clinical isolates.

Body growth and substrate partitioning for fat and protein gain in weaned BALB/c mice treated with growth hormone.

Previously we have found that recombinant human growth hormone (rhGH) (GH; 74 ng g body wt.(-1)) administration to weaned BALB/c male mice (fed 12% or 20% protein diet) induced a growth lag and subsequent repletion similar to the catch-up growth process. We studied the partitioning of feed and protein intakes between adipose and protein body stores through the linear relationships among them.

Feed intake and protein skeletal muscle in growing mice treated with growth hormone: time course effects.

The exogenous recombinant human growth hormone (rhGH) administration on gastrocnemius muscle growth performance and its contribution to body growth of male and female BALB/c mice fed a 12 % protein diet from 25 to 50 days of age, as well as the mechanism of utilization of feed intake to the lean muscle deposition were studied. Male and female weaning mice (21 days of age) were injected subcutaneously for 29 days with rhGH (74 ng x g(-1)) or saline vehicle (control). Feed intake and body weight (BW) were measured daily.

Diagnosis of candidosis by amplification of small subunit of 18S rRNA gene.

A PCR assay for the diagnosis of infection produced by Candida sp. was developed. The primers, designated 520 and 522, were selected from highly-conserved areas of the small subunit (ssu) 18S rRNA gene of Candida spp.

Recombinant human growth hormone modifies the inherent partition of nutrients in growing female and male BALB/c mice.

BALB/c mice weaned at 21 days were used to investigate the effects of exogenous recombinant human growth hormone (rhGH) administration on the growth performance and carcass composition in females and males allowed to consume feed ad libitum. Forty mice were assigned within each sex (female [F] and male [M] to treatment of either 20 microL g-1 saline (Fs and Ms groups) or 74 ng rhGH g-1 body weight (BW) in 20 microL saline (FGH and MGH groups). At 50 d of age the mice were weighed and then killed by cervical dislocation.

Serratia rubidaea as an invasive pathogen.

Serratia rubidaea biotype 1 was isolated from the bile and blood of a patient with a bile tract carcinoma obstructing the common bile duct and who underwent invasive procedures. The infection was cleared after adequate treatment with antibiotics.

Muscle cell growth in protein deficient rats following administration of sheep red blood cells.

In order to observe the effects of sheep red blood cells (SRBC) administration on the muscle cell growth in malnourished states, adult male Wistar rats (135 +/- 10 g 10 animals per group) subjected during 30 days to 1% and 10% protein diets, were injected (i.v.) either 15.

[Blood glucose, insulin, GH, and amino acids in rats receiving 3 levels of dietary proteins].

The effect of dietary protein content on the variations in plasma insulin, GH, glucose and both gluconeogenic and branched-chain amino acids (BCAA) levels, was studied in Wistar rats. For 21 days animals consumed ad libitum diets containing 4% (LP group) 10% (MP group) or 20% (HP group) protein. Body weight gain and plasma concentrations of the glucose, insulin and both the insulin/glucose (I/G) and insulin/GH (I/GH) ratios varied directly with the protein content of the diet.

[Cell growth of skeletal muscle as an indicator of protein requirements of the adult rat].

Skeletal muscle growth, muscle nucleic acids and muscle protein synthesis capacity, were measured to evaluate the protein requirement of adult rats. Wistar rats were fed on diets containing 4%, 10% or 20% casein + D,L-methionine. All diets were provided for 21 days beginning at 90 days of age.

[Influence of dietary protein levels on the electrophoretic pattern and plasma IgG and IgM levels in pregnant rats and their offspring].

In view of the influence that nutritional and physiological status exert on the immunological capacity of the subject, a study was carried out for the purpose of studying the changes induced by three protein levels in the diet: (4%, 10% (control), and 20%) on total plasma proteins (TPP) and their fractions, as well as Ig G and Ig M levels in non-pregnant (NP) and pregnant (P) rats and their offspring. Effect of the diet on adult rats--In non-pregnant rats submitted to the high protein diet, Ig G levels increased while TPP decreased in P rats fed on 4% and 20% protein diets. The higher the protein level in the diet, the higher were the TPP values.

[Changes in the metabolism of muscle RNA in rats given a high protein diet].

The effect of a high protein diet (20% casein + D,L-methionine) administered to adult Wistar rats on some aspects of muscle RNA metabolism has been studied. Body weight increased in spite of lower intake. However, gastrocnemius muscle remained unmodified, although protein content increased.
