Triatoma baratai Carcavallo & Jurberg, 2000, a species similar to Triatoma williami Galvão, Souza & Lima, 1967 andbelonging to the T. matogrossensis subcomplex, was described based on a male specimen collected in a sylvatic environ-ment, near a cave, in Bonito county, Bodoquena mountain range, state of Mato Grosso do Sul, Brazil. In the present workwe describe the female of T. baratai, captured in a chicken house, in Nioaque county, state of Mato Grosso do Sul, Brazil.Furthermore, we recorded the occurrence of T. baratai in domiciles and peridomestic environment in another four munic-ipalities (Bodoquena, Bela Vista, Corumbá, and Miranda), extending its geographical distribution. Finally, we present a key to the species of the Triatoma matogrossensis subcomplex.

Fattening Period

The quantification of emissions of greenhouse gases from human activities is of prime importance for determining the importance of their effect on the environment. The aim of this study was to test a hypothesis that the interior concentration and emission of carbon dioxide in chicken housing is impacted by the age of animals and season of fattening period. Carbon dioxide (CO<sub>2</sub>) concentrations and emissions were assessed over six fattening periods in total. The major part of CO<sub>2</sub> seemed to have its origin in bird respiration with assumed production of approx. 147 kg of CO2/h. CO<sub>2</sub> emission was most affected by chickens towards the end of the grow-out period (P &lt; 0.001) taking dominance over the process of natural gas burning by heaters. The mean CO<sub>2</sub> emission from the chicken house ranged between 120 and 247 kg/h in the first quarter of periods and between 325 and 459 kg/h in the last ones. The heaters could be theoretically a possible source of approx. 39 kg each hour if they worked continuously. CO<sub>2</sub> emissions were considerably more affected by ventilation rate (P &lt; 0.001) than by CO<sub>2</sub> concentration in the indoor air.

Chicken House

In view of the problem that some chicken farms are susceptible to various bacteria and viruses due to poor breeding environment, this paper designs a chicken house environmental intelligent monitoring system based on single-chip microcomputer application to improve the chicken house environment. The system adopts STC89C52 single-chip microcomputer as the main control chip. The sensor collects information on the light intensity, temperature and humidity, and carbon dioxide concentration, and controls the exhaust fan and the illumination lamp, and the environmental parameters can be displayed on the display in real time.

ABSTRACT Using PCR, we screened 105 isolates of poultry-associated Campylobacter jejuni for the presence of class 1 integrons. Of those isolates, 21% (22 of 105) possessed the integrase gene, but only 5 isolates produced an amplicon in a 5′-3′ conserved sequence PCR directed toward amplification of the resistance cassettes. DNA sequencing demonstrated that all five isolates possessed the aminoglycoside resistance gene, aacA4.
